6 To Make Something Makes You Happy Masahiro Mori, a professor emeritus of Tokyo Institute of Technology, (Dr. of Engineering) President, MUKTA Research Institute Born in 1927, Masahiro Mori is a professor emeritus of Tokyo Institute of Technology, and known as the founder of Japan's robot game contests. He is the president of the Central Committee for the International Robot Games Festival (RoboFesta). He says, " When you try to make something, for example, a robot, it takes you to bring out your inner creativity. You have a chance to experience the thrill of competition and to have a sense of accomplishment. In making things, you are the owner of the whole process from scratch to the final stage. It will energize you, giving you a chance to think it over, and to experience how it is enjoyable to work together with your collaborators." This article is about why he advocates a joy of "making things" based on his long and versatile experiences in promoting robot game contests, the first of which dates back to In this article he also mentions briefly the products of NAiS, in particular, relays. Relays are one of the key components to assemble the hardware of the information age, including robotics products. They are used as switches, sequence controllers, isolators, and/or delay circuit components. Today, two types are available. One is a semiconductor relay featuring compact size, high-speed signal processing and long-life, and the other is a conventional mechanical relay that withstands excess overloading or surge voltages. He never fails to mention that he likes the latter because they sometimes emit sound or even light. They are in a sense communicable with people, while the former is virtually encapsulated in a black box. 6

9 From Mechanical Relays to Solid-state Relays Matsushita Electric Works established technologies and research track record continue to deliver customer satisfaction. In December 2002, Matsushita Electric Works merged its mechanical and solid-state relay divisions into a newly created Switching Devices Division, in order to strengthen its relay operations as a whole. Integrating operations to take advantage of relay strengths Matsushita Electric Works biggest aim in merging the two divisions was to offer its customers the best choice for their needs. The company will offer each customer the optimum relay for its applications, without being confined to the frameworks of mechanical/semiconductor relays. PhotoMOS relays have grown exponentially along with the IT sector Matsushita Electric Works Signal relays and PhotoMOS relays deliver the compact size, high speed, and energy efficiency demanded in such IT fields as info-communications devices and measuring instruments. Offering total relay solutions The company will also actively enhance its capabilities in non-it growth fields and fields with a dearth of products. The true advantages of the SSR are now beginning to be discovered for such fields as automotive components, industrial devices, and consumer electronics. Actively introducing relays for each of these fields will allow Matsushita Electric Works to offer the total relays solutions capabilities that its rivals will be unable to imitate. High functionality is the key for industrial devices Matsushita Electric Works has developed a new circuit that automatically shuts off relay output in the event of a short circuit loads. In 2001, it launched sales of the GU SOP with short circuit protection equipped relay, the world s first PhotoMOS relay with a short circuit protection function. This product retains the functionality and compact SOP package of conventional GU SOPs. Additionally, the elimination of the need to add an external protector circuit allows for a more compact system, and also reduces the cost of the system as a whole. SSRs, the ideal choice for AC-power control Most industrial devices and consumer electronics are ACpower controlled. Matsushita Electric Works has launched sales of a number of new products in 2002 that have greatly exceeded expectations. These include three SSRs the AQ-K and AQ-R for industrial devices, and the AQ-H for consumer electronics and the APT phototriac coupler. The Phototriac Coupler (APT) is the core chip of the SSR, and the company has developed a new product that allows it to manufacture more compact, more feature-rich, and cheaper SSRs. The company is committed to leveraging the advantages of its SSRs to develop unique products that its rivals cannot duplicate. The goal: Offer the optimum solution for any field Matsushita Electric Works is committed to offering its customers the best and easiest-to-use products for any field, from industrial devices, to info-communications devices, to consumer electronics and automotive components. The ultimate aim of this integration is to offer the optimum solution not available anywhere else, no matter what the relay application. 9
