Manufacturing HDD-use suspension parts with 3-92-1, Asanishi, Ogaki City Gifu Prefecture precision mold machining technology Established in 1968 TEL +81-584-89-5811 http://www.ogakiseiko.co.jp Katsuhiro Ueda President The suspension parts of hard disk drives (HDDs) are precision parts designed to retain the magnetic heads at intervals of 0.01 micrometers. These can be manufactured by only four manufacturers in the world. The clearance between the magnetic head and the magnetic disk of an HDD corresponds to the flight of a jumbo jet at a height of no more than 1 mm from ground level. HDDs used in personal computers, HDD recorders, and other equipment have a magnetic head for reading recorded data from the magnetic disk at the tip of the suspension part. The clearance between the magnetic disk and magnetic head is required to remain 0.01 micrometers (about a dozen nanometers). This is as precise as the flight of a jumbo jet at a height of no more than 1 mm from ground level. A group of creative manufacturers centering around ultra-precise molds HDD-use suspension parts are manufactured by using the technologies for mold machining, stamping, and production that the corporation has newly developed based on the technology for manufacturing molds for electronics parts that the corporation has been cultivating. Only a few corporations can manufacture these suspension parts: Two in Japan and four in the whole world. Dedication to creative manufacturing with a human touch Ogaki Seiko works to enhance its expertise with the teamwork of its employees in the workplace, centering on engineers, with the world's high technology in perspective. Ogaki Seiko has thus achieved original and advanced technological development. The developed technology is designed not only to make machines and robots producing products but also to dedicate the corporation's energy to creative manufacturing with a human touch, thus producing advanced unrivaled products.

The product enjoys a share of 85% in Japan and 30%worldwide. High performance required of automotive fuses used under severe conditions The electrical circuit systems of automobiles are becoming increasingly complex and diversified, resulting in ever-increasing demand for automotive fuses. The systems thus meet not only basic requirements for vibration resistance and durability but also for cost reduction and for various other demands such as those for down sizing, light weight, and multiple circuits. The company also develops multiple fuses compatible with multiple circuits, along with Slow Blow Fuses (which are automotive high-current fuses) and EV fuses for hybrid vehicles. The company's fuses are used in most of the vehicles produced in Japan and South Korea. Highly devoted to product quality, the company owns Japan's only certified laboratory. The company owns its own laboratory certified under ISO/IEC 17025, a international laboratory standard. It is the only laboratory in Japan that is designed for fuses and other over current protective equipment. The test results obtained there are designed to certify the conformity of products to international standards. The acquisition of a certification for this laboratory is indispensable to the company's future expansion of sales channels leading to Western automobile manufacturers. Displaying its unique development capability in precision metal pressing as well The company displays its unique development capability in precision metal forming, yet another pillar of the company's business. At a cost lower than precision processing of plastic resin, the company has developed a technology for precision metal forming. The company developed the technology for ultra-precision metal forming by deep drawing in an attempt to expand business in such areas such as cans for safe and precise rechargeable batteries for automotives. Automotive fuses and related products Cans for rechargeable batteries 177 Kato Manufacturing Manufacturing Co., Ltd. automotive-only gas 2-6, Himegaoka, Kani City sensor covers by using Gifu Prefecture metal pressing technology Established in 1949 without deburring TEL +81-574-60-0006 Kazuo Kato http://www.ksj-group.com/ President The company's development of pressing technology that obviates the need of deburring and other downstream operations in metal pressing allows the company to enjoy a world share of 50% for its automotive gas sensor covers. Manufacturing automotive gas sensor covers by metal pressing alone, without downstream operations Gas sensors on automotive engines have a hole in the side of the sensor cover to detect gas concentration. These sensor covers are made by drawing a flat metal plate into a tube and then drilling a round or square hole in the side. The company has developed a technology for performing these machining operations with a single press machine. What is more, the absence of scratches and burrs in the pressed product with equal wall thicknesses allows the company to enjoy a world share of 50% in manufacturing automotive sensor covers. "Art" inherited from skilled workers to youths, then from parents to their children The skills of skilled workers targeting a defect incidence of zero are an "art" learned through long years of experience. The company is also committed to conveying this "art." In the workplace, the importance of creative manufacturing is passed down from skilled workers to youths, and from employees to their children by building a workplace environment workers can be proud to pass on the next generation. Statistics are the compass of management The compass of management is "A History of Japanese Economy," which the company compiled by chronologically organizing housing startups, numbers of automobiles registered, and other statistics published each year. The company's decision to shift from parts of clocks and combustion equipment (which the company had previously produced) to automobile parts was motivated by the fact that those statistics had never shown the number of automobiles registered declining from the preceding year. Automotive gas sensor covers Pressed metal products 178 CCI The world's top-ranking Corporation brake fluids and engine coolants manufacture 12, Shinhazama, Seki City Gifu Prefecture ensures vehicle safety and reliability Established in 1949 TEL +81-575-24-4111 Shuji Okabe http://www.ccijp.co.jp President CCI produces the world's top-ranking quality engine coolants and brake fluids that allow vehicles to safety "go" and "stop." CCI products enjoy a 19% world market share and a 60% domestic market share .CCI Brake Fluids and Engine Coolants are engineered to achieve high specifications, quality, and performance results Brake fluids are required to exhibit high boiling points, low-temperature fluidity and other characteristics, including prevention of the deterioration of rubber parts to ensure safe, stable braking. On the other hand, engine coolants are required to provide excellent cooling and anti-freeze properties as well as other characteristics, including protecting the cooling system from rust and corrosion, which allow vehicle engines to achieve maximum performance. Commitment to driver safety has resulted in the world's top-ranking quality In the postwar years when all brake fluids available in Japan were of low quality, the company conducted accident surveys and driving tests in various parts of the country in an attempt to develop
