When the light is green, you can also cross the road diagonally. Tokyo is one of the places where you can see this extremely effective idea in practice. Connections 7 The world of connections Connections 8 being together. Nobody knows how the lovelocks tradition began. One thing we do know is that they are very heavy! So heavy, in fact, that the first bridge railing in Paris collapsed under their weight in 2014. Connections 9 The world of connections Connections 10 coming together. Torii are traditional Japanese gates. They mark the transition from the earthly to the sacred world. Whenever you walk through one of these gates, you’re either entering or leaving sacred ground. forging together. A sharp connection: Damask knives are manufactured by hammering alternate layers of hard and brittle steel together then folding them over and repeating the process. The result is an extremely sharp, robust and flexible blade. communicating together. They may not be able to speak, but glow worms communicate with each other using light signals. The signals vary in length and rhythm, and different species of glow worm use different signals. folding together. Furoshiki are square shaped pieces of cloth that are traditionally used in Japan as eco-friendly gift-wrapping or bags. There are countless furoshiki techniques, offering all kinds of creative wrapping solutions. Follow our instructions on how to make your own furoshiki on page 29. mixing together. Chocolate and bacon anyone? Food pairing is an entirely new approach to creative cooking that mixes foods with complementary flavours in unusual combinations. Connections 11 The world of connections Connections 12 tying together. The obi – or sash – is tied into an artistic knot at the back and holds kimonos together. Connections 13 kimonos – “the thing to put on”. When it comes to traditional clothing, the Japanese kimono is equivalent to the Scottish kilt. Although kimonos are no longer seen on an everyday basis, they are still worn in the home, on special occasions and in traditional tea-houses. The word kimono is derived from “kiru” (which means “to put on”) and “mono” (which means “thing”), so it simply means: “the thing to put on”. The T-shaped, straight-cut robe has its origins in China, where it was worn as an undergarment. Its current design stems from the Heian period (8th to 12th century), although it has undergone several modifications between then and now. There are many kinds of kimonos that differ in their cut, pattern and colour scheme: for married women (tomesode, kurotomesode), single women (furisode, kofurisode and koburisode), married and single women (tsukesage, houmongi, iromuji, komon, edokomon), brides (uchikake and shiromuke), burials (mofuku), men and children (hitotsumi) and kimonos for recreational activities (yukata), geishas (susohiki) and their apprentices the maikos (hikizuri). The keikogi – the training outfit for Judo, Kendo, Karate and Aikido – is also based on the kimono. The most elegant and complex kimono, the junihitoe, which means “twelve-layered robe” can be seen in Japan’s imperial palace Despite the diverse range of kimonos, in the past they were only available in one size, as they were cut from a single, standard-size piece of fabric. They were adapted to the wearer’s body by tucking and folding. Today, they are available in different sizes. A brand new, high-quality kimono can easily cost more than EUR 10,000: hand-sewn, hand-woven and hand-embroidered silk fabrics are expensive, which is why many people buy second-hand kimonos. A complete kimono outfit, with all the accessories, can cost more than EUR 20,000, as the obi, the stiffened sash used to bind the kimono at the back, is very complex to make and therefore very costly. Like many traditions in Japan, putting on a kimono is an art unto itself. Only recreational and everyday kimonos can be put on without any assistance, otherwise you need the help of a friend or a professional dresser. The latter often work at hairdressing or cosmetic salons, although they also come to the wearer’s home. In addition to the kimono and the obi, the up to three-and-a-half-metre long sash, which is artistically bound into a taiko (drum knot) at the back, there are nine other accessories: the undergarment, two waist sashes, a scarf, two additional ties, the obijime (a cord), the obita (a piece of cardboard around which the obi knot is tied) and the obimakura, a bustle pad that supports and shapes the knot. Together, they create an impressive work of art, and, just like the tea ceremony or sushi, represent Japanese artistry and tradition. Special Olympics Connections 14 Connections Imagine a major sporting event where the best-of-the-best come together to compete against each other, for example a track event such as the 200-metre sprint involving the world’s top athletes. Now imagine one of the athletes tripping and falling half way down the track. The other participants notice and run back to help their comrade back on his feet. They ask him if he’s OK. When he says “yes”, they all set off again, running towards the finishing line together. You may think that doesn’t happen, and you’d be right… almost. The Special Olympics are held every two years alongside the World Championships and the Olympic Games, and here you do see it happen. These Olympics are slightly different to the other events: as the name suggests, more special. A visit to the Special Olympics. Very unique games. 4,800 mentally handicapped athletes competed at the Special Olympics 2014 in Düsseldorf to celebrate their love of sport – an even bigger event than the Paralympics 2012 in London. For one whole week, Düsseldorf was the scene of exciting contests and emotional moments. It was the biggest event Special Olympics Germany had ever organised, with more than 14,000 competitors, 1,700 trainers, 1,500 family members and 2,000 volunteers. Photo: Special Olympics Deutschland e.V. winning together. On the morning before the first events, you could already sense the unique excitement of the Special Olympics in the air at Düsseldorf Central Station. Many of the athletes, dressed in their team uniforms, stood on the platform waiting for the underground train to Sportpark Arena. Their T-shirts displayed the logos of Caritas, AWO, Diakonie and other disabled workshops and organisations. They were clearly in an excellent mood and very excited to be there. The contingent from Helen Keller School in Ratingen certainly made its presence felt, chanting, “Higher! Further! HKS!” Their enthusiasm for their team was no different from “regular” sports fans – and why should it be? 15 Special Olympics Connections 16 The Special Olympics regatta is held at Unterbacher See, a large lake in southern Düsseldorf. Two-person Unified Kayaks line up at the start alongside regular boats. Meanwhile the Unified equestrian-vaulting event is taking place just a few kilometres away at Reitpark Eller. In Unified Sports, people with and without intellectual disability train and compete together. They learn from each other and break down everyday barriers. Unified Sports adopts three different approaches: The goal areas on the football pitches are tense. No player is giving an inch in the attempt to capture the ball. But there aren’t any fouls and the referees don’t have much to do – not least because there is no offside in the slightly simplified rules. The atmosphere at the other events is quieter, including on the tennis courts: “Quiet, please!” as the umpire says at Wimbledon. Performance In this competition-based approach, athletes and their partners prepare for the Special Olympics. Participants are usually similar in age and performance level. Sport is fun – and much more. Learning The development-based approach is intended to ensure that the weaker athletes benefit and learn from the stronger sportsmen and women. The Special Olympics The Special Olympics is the world’s largest sports organisation for people with intellectual and multiple disabilities. The aim is to help people with disabilities increase recognition, confidence and social participation for themselves through sport. The Special Olympics was founded by Eunice Kennedy-Shriver, John F. Kennedy’s sister, in 1968. Eunice wanted to give their sister Rosemary and other people with intellectual disabilities the opportunity to participate in sports. Almost 50 years In Gerresheim, in eastern Düsseldorf, 203 participants are competing in the singles, doubles, team and Unified events (more on Unified Sports below) inside the big bocce hall. Laughing Finally, in the leisure-based approach, the focus is simply on enjoying sport together. The Special Olympics version of bocce has eight balls (four balls each in the singles event) and the smaller pallino ball. The aim is to throw the larger balls as close to the pallino ball as possible. The game is over as soon as one of the players scores 16 points. Regular training is not only fun, it also boosts the athletes’ self-confidence and improves their powers of concentration and coordination, as well as their perseverance (a game can sometimes last up to three hours – although at the Special Olympics the athletes also play against time). You can see the concentration in the players’ faces as they step up to the line, kneel down, squat or position themselves in their wheelchairs, and take careful and considered aim at the pallino – before rolling the ball with precision to get as close to the pallino as possible. Bocce is special because it can be played by people of any age and with almost any disability. Unified Sports benefits both athletes and their non-handicapped partners, who are able to improve their social skills such as the teamwork and fair play. Playing sport together favours positive social interaction between team colleagues and they often develop close friendships. As awareness for Unified Sports increases, more people are getting involved. There are currently 840 athletes and 625 partners training together, a development that was reflected in the Düsseldorf games: 260 Unified Sports partners took part compared to 151 in 2010. The next Special Olympics will be in Hanover in 2016. The doubles, team and Unified Sports events also encourage social integration among people with and without disabilities. 17 Unified Sports – strong together. It’s business as usual at Sportpark Arena in northern Düsseldorf. The home ground of German second-division football club Fortuna Düsseldorf is alive with hustle and bustle. The Special Olympics has different venues for football, table tennis, powerlifting, tennis, cycling and beach volleyball. Despite the competitors’ outstanding sense of fair play, you can still feel their determination to win, reflecting the Special Olympics’ athlete oath: “Let me win! But if I cannot win, let me be brave in the attempt!” Photos: Special Olympics Deutschland e.V. Yellow card? Not today! Connections Why don’t you attend – as spectator, competitor or new Unified Partner! You won’t be disappointed. later, what was initially a good idea has evolved into a global movement with almost four million athletes in 170 countries. In Germany, Special Olympics Deutschland now represents more than 40,000 athletes who train at more than 1,100 member organisations. Mitsubishi Electric provided an XXL monitor for the Special Olympics 2014 as part of its support package for the event. In addition, 10 employees participated as corporate volunteers. Big in Japan Connections 20 welcome to infrastructure island. HONSHU 230,500 km² 01 Hokkaido → Honshu Seikan Tunnel. The tunnel connects Hokkaido and Honshu. At 53.85 km in length, it is one of the longest tunnels in the world. 23.3 km of the tunnel is at a depth of up to 240 m below sea level, which makes it the tunnel with the second- longest undersea section after the Eurotunnel. 02 Honshu → Shikoku Akashi Kaikyo Bridge. There are three bridges connecting Honshu and Shikoku. One of these is the Akashi-Kaikyo Bridge. With a 1,991 m central span, it the longest span bridge in the world. Onaruto Bridge. While most bridges connect, the Onaruto Bridge separates. The ferry service across the Onaruto Strait was stopped when the 1,629 m long bridge was opened. Since then, pedestrians, cyclists and small cars up to 3.4 m in length and 660 cm³ haven’t been able to reach the other side. Seto Ohashi. The Seto Ohashi Bridge is the collective name for three suspension bridges, two oblique suspension bridges and one truss bridge. There are also four viaducts. They have upper and lower levels with cars using the upper level and trains the lower level. With a total length of 13.1 km (9.3 km above water), it is the longest double-storey bridge in the world. the four main islands. SHIKOKU 18,000 km² The Japanese archipelago consists of four main islands that are only separate from each HOKKAIDO 83,456 km² Japan is an island state. The country is made up of around 6,850 islands and islets (giving a precise number is tricky, as new islands emerge every now and again as a result of volcanic eruptions). The “mainland” consists of four islands: Hokkaido in the north, the large central island of Honshu, as well as Shikoku and Kyushu in the south. They are only separate from each other on maps. In reality, they are connected – by bridges, tunnels or ferries. other geographically. Japan’s KYUSHU 35,640 km² more than 126 million citizens are connected via bridges, ferries, tunnels and airlines. 03 Honshu → Kyushu Hayatomo Strait. The narrowest point of the strait is only 600 metres wide and it would soon be connected by land if the 15 cm of sand that is deposited there every year wasn’t regularly dredged. The Kammon Bridge, plus several car bridges, railway bridges and a pedestrian tunnel provide safe and dry passage to the other side. Hokkaido 04 Shikoku → Kyushu Bungo-suido. No bridge and no tunnel, just water and three ferry services. The fastest of them takes around 70 minutes to travel from Misaki on Shikoku to Saganoseki on Kyushu. 03 Honshu 01 02 05 Kyushu → Ryukyu Island Tokio Kawasaki Okinawa. To get to the south of Okinawa you either need a plane ticket or plenty of time. The weekly ferry from Tokyo takes 44 hours. There’s a quicker service from Kagoshima – it only takes 25 hours. Saganoseki Misaki Shikoku 06 The Bay of Tokyo The Tokyo-wan-Aqua-Line crosses above and below Tokyo Bay. Rather than crawling through 100 km of Tokyo city streets, drivers can now use the 10 km tunnel, the longest underwater car tunnel in the world, and a 4.4 km long bridge to get from Kawasaki to Kisarazu in just 15 minutes. Connections Kyushu Kagoshima 04 05 Ryuku Islands Okinawa Kisarazu 06 21 Power semiconductors Connections 22 Connections what are power semiconductors? Power semiconductors are electronic components from power electronics, a field of electrical engineering that, in the broadest sense, deals with the electronic conversion of electric power. If we take a small consumer electronics device such as an MP3 player or smart phone, a conventional Lithium-ion battery runs on 3.7 volts (V). While the device’s processor needs 3.3 V, the display might need 12 V and the I/O (input/ output) controller that controls writing and reading processes 5 V. Power semiconductors deliver the right amount of voltage to the right component. Alternatively, have a look at your mobile-phone charger. Does the label say 100–230 V? Then it has a power module built into it. If you still own an older type of charger, hold one charger in each hand. The older charger, which has a copper transformer, will feel much heavier. Power semiconductors are lighter, generally less expensive and, unlike transformers, they can cope with a wider range of voltages. In addition, the electronically controlled output voltage is always the same and the efficiency far higher at up to 95 %. High efficiency makes power semiconductors an interesting option for many different applications, as it reduces energy losses. Insulated gate bipolar transistors (IGBTs) are used in the power range from several kilowatts to several megawatts. Switching Power supply (on/off) transistors Transforming AC/DC, DC/AC, frequency Controlling Power supply (more/less) Variable-speed drives are a typical application area. In this case, power semiconductors ensure, for example, that the drive engines in modern suburban trains receive the power they need to accelerate quickly back to cruising speed after stopping at a station. This is the only way for the trains to make good progress if there are many station stops. On the other hand, when the brake is applied before a station, the kinetic energy of the entire train is fed back into the overhead line with very low losses. Power semiconductors are also used for renewable energy applications. Photovoltaic systems generate direct current (DC). This current has to be converted into alternating current (AC) by inverters so that the electrical energy can be fed into the grid. Another key application is power transmission across long distances. High voltage direct current transmission (HVDC) is regularly discussed in this respect, as it facilitates high transmission capacity with low line losses. Power semiconductors are used to convert power in these HVDC systems. Even in the event of a power cut, we need power semiconductors such as IGBTs: they play a key role in ensuring an uninterruptable power supply (UPS) at data centres and other critical installations, where again they demonstrate excellent energy efficiency and reliability. www.mitsubishichips.eu Mitsubishi Electric power semiconductors.

Linking real and virtual worlds – the Industry 4.0 manufacturing trend. Photo: Festo AG & Co. KG the fourth industrial revolution has begun. Industry 4.0 Connections 26 Perfect part has built-in sensors that continuously monitor its condition. It automatically reports an impending defect, or wear and tear, to the operator and manufacturer. At the manufacturer’s, a machine autonomously processes the data received from the vehicle part and promptly produces the replacement part. As the worn part has also communicated its location, delivery and on-site installation of the replacement part can be scheduled automatically. interaction. Industry 4.0 is based on information exchange. All components communicate with each other and share data. This means, for example, that a chipped vehicle component can report its impending breakdown and initiate the production and installation of a replacement. Industry 4.0 This mass customisation production concept is one of the key features of Industry 4.0. It offers the benefits of mass production (such as economies of scale, learning curve effects or simply automation), but can still cater to the growing trend of customised products. Opportunities for Germany. Even the strong German economy is feeling the impact of globalisation, as it is now faces competition from low wage countries. Demographic change brought about by an ageing society has also resulted in a shortage of qualified labour. Industry 4.0 could be the answer to these challenges. The integrative, highly efficient manufacturing concept is a solution for more flexible and less expensive production that is sustainable and satisfies global requirements. The high level of automation will therefore master both economic and social challenges. You can’t not communicate. The idea behind Industry 4.0 is the all-encompassing networking and integration of production equipment, databases and products. Networking is possible as a result of the progressive miniaturisation and optimisation of computer chips. Today, even the smallest computers can share information via the Internet or Cloud. Intermediate products provide machines with instructions via barcode or RFID chip. They are adaptive and ensure that machines operate correctly. The communication of all objects with each other as well as autonomous decision-making processes create an Internet of Things where the real and virtual worlds merge into cyber-physical systems. Intelligent networking is altering the entire production logic – not only in relation to machines, products and warehousing, but also logistics, after-sales service and marketing, as illustrated in the following example: a chipped vehicle 01 First industrial revolution: rapid mechanisation of factory operations after the invention of the steam engine One concept, many advantages. The high level of adaptability and quick change of product will make it possible to achieve an extremely high individualisation of production. These factors will enable highly flexible mass production in which even custom-built individual products are possible without significant effort. Industry 4.0 is the current catchword for automation technology. After the steam engine, mass manufacturing and digitisation, we now appear to be on the threshold of the fourth industrial revolution. This affects us all, as it comes not only with introduction of new technology, but also a permanent restructuring of economic, employment and social frameworks. Connections Mitsubishi Electric is actively promoting 4.0. The significance of Industry 4.0 for the German economy and Germany as a business location is evident in the fact that three sector associations – BITKOM (the German Association for Information Technology, Telecommunications and New Media), VDMA (the German Mechanical and Plant Engineering Association) and ZVEI (the German Electrical and Electronic Manufacturers’ Association) – have joined forces to define standards and take the project forward. Mitsubishi Electric is also convinced by the idea and, as the largest automation supplier to the Asian market, has adopted the “German approach” to Industry 4.0 in Asia. Mitsubishi Electric is a long-serving member of the industrial associations VDMA and ZVEI and intends to play an even more active role in the definition of Industry 4.0 standards. 02 Second industrial revolution: mass manufacturing is possible as a result of conveyor belts and electrical power 03 Third industrial revolution: The “digital revolution” resulted from digitisation and the widespread use of electronics and IT 04 www.plattform-i40.de Fourth industrial revolution: Industry 4.0 – networking the real and virtual worlds via cyber-physical systems 27 Sudoku Good to know Electric people Connections 28 sudoku. 4 Enter the numbers 1 to 9 in the grid so that each number appears only once in each column, row and block. 1 3 5 8 1 Happy puzzling! 6 4 6 7 2 Japan has a history of sophisticated wrapping solutions.

It can absorb heating energy from the air in an ecological, low-cost process (even when the outdoor temperature is as low as –20 °C) thanks to Zubadan technology. The storm flattened more than 34,500 trees in Düsseldorf, many of them large and old. Many sports fields, openair swimming pools, kindergartens and youth centres were also destroyed. In the wake of all the chaos, we are sowing the seeds of hope – so that Düsseldorf will be as green as it was before the storm in a few year’s time – by donating a five-figure amount to the “New Trees for Düsseldorf” initiative. The R&D 100 jury selected two of our automation products for the 2014 awards. Known widely as the “Innovation Oscars”, the R&D 100 Awards are presented to the most pioneering technological developments over the past year.

The edges of the skis, the bindings and the boot absorb the forces generated and guide the skier’s steering impulse. Mitsubishi Electric brings innovation to the piste. Salomon, based in Annecy in the French Alps, is one of the leading companies in the winter sports sector. This is mainly due to the safety binding invented by the company’s founder, Georges Salomon, many years ago. It ensures that the binding automatically opens if the skier falls, thereby preventing injury. Even now, Salomon is still developing many impressive and pioneering innovations for ski boots and bindings. In the development process, the designers and engineers use a Mitsubishi Electric MV2400S wire EDM. It ensures that prototypes are not only made with flawless quality, but also exceptionally quickly. It’s very wise, as the company that launches its ski product first usually wins the race. www.salomon.com tighten a screw. 3 Our MSZ-FH25VE air-conditioning system was rated the number one product in the Stiftung Warentest magazine (issue 7/2014).
