These are the secret tactics for the environment-friendly creation of products in Japan, which is adopted by the engine components of F1 racing cars and fuel-efficient world strategic cars. Creative technologies that even patent lawyers had difficulty to understand
A minute concave surface is formed on a metallic surface (a puddle of oil) through hammering metallic microparticles on the metallic surface at high speeds. This realized the ultra-low friction. In the fields of technologies of finish for surfaces, large particles were hammered and effects were enhanced at that time. This used to be the common sense around that time. The technologies created based on an extremely abnormal idea “to use microparticles” gave a difficult time for the patent lawyers to make descriptions of the same for patent application.
Whose technologies will result in a victory of the Formula One championship?
Engine is a heart of the vehicle. As for a car for the Formula One championship, endurance in extreme situations can be expected. Combined with the nature of ultra-low friction, the surface hardness become extremely improved through such technologies of finish for surfaces, as if a swordsmith worked a metal by a thick hammer for a Japanese sword. Worldwide racing teams adopt such technologies. It is said that they cannot win races unless they have such technologies.
Environment-friendly secret tactics in Japan
Reduction of burdens on the environment is one of the major directions that are expected to the development of vehicles. The technologies of the company have been adopted by compact strategic cars for a Japanese automobile maker whose selling point is fuel efficiency, which results in enhancement of international competitiveness of Japanese cars. It is said that when metallic particles are changed to titanium, a 20% increase concerning gas mileage for diesel-powered vehicles occurs based on a high effect of oxidation-reduction. Life of industrial tools and precision metal molds will be prolonged from an increase from several times in the length to dozens of times. This can also reduce resistance and noise of slide portions. The technologies of the company support the strength of creation of products in Japan as the secret tactics.

The company implemented its own improvements in regards to the production facilities, and built the know-how that does not allow major companies to reach the same level. The company engages in new materials and new methods of processing, and conducts product development that can respond to various needs of customers.

In regards to the forged gears of manual transmission for automobiles that are manufactured based on the micron-sized precision through ultra-precision forging technologies, caused by the skills of a goldsmith that forges a Japanese sword, the company obtains 70% of the world share. Forging technologies that innovates a method of manufacturing of gears
In regards to manufacturing of gears of manual transmission for automobiles, gear-cutting (hob) and finishing of gear tooth surfaces (shaving) were cut and processed. However, the company developed the technologies to manufacture a complex-shaped gear with high strength and high precision through raw materials (billet) based on only the general-purpose pressing machines and Dies.
Forging technologies that contribute to compactness and reduction in weight of automobiles
In regards to gears that are manufactured through high-precision and special Dies used for forging, a 30% strength of teeth applied compared with the teeth made by cutting tools. And the “shift feeling” for drivers has been remarkably improved due to smoothness of the gear surfaces. Additionally, 2 gears of clutch gear and main gear are integrated. And it is possible to recess one of the gears. These factors lead to remarkable compactness and reduction in weight of transmissions for automobiles.
Advance toward the technical development without fear of failure and achievement of 70% of the world share
With an aim of the world-class “only one technology,” the company started to develop forged gears 30 years ago. It believed that it had its own technologies which made the impossible come true. Based on such idea, the company promoted technical development. As a result, the company has performed direct transactions with domestic and international major automobile makers as a company that can offer a proposal. And the company obtains 70% of the world share in regards to the forged gears for manual transmission concerning foreign automobile makers.

Mass-production of a 140-1 Kita Komukai-cho Toyohashi City “1/1,000,000 g” gear Aichi Prefecture
through the precision Establishment: 1965 injection molding TEL +81-532-31-2061 Motoo Matsuura President http://www.juken.com
The main product of the company is called “Powder Gear” with 0.147 mm in diameter as an ultra-compact resin gear. Its weight is “1/1,000,000 g” which can allow such gear to be placed on a grain of rice due to its lightness. The high-precision injection molding technologies regarding hyperfine plastics are the world’s leading technologies. Aim of the world’s smallest components
The development of such hyperfine components that are not apparent to the naked eyes was started through the expectation of the present President because “ultraslim and light components” would become the future trend. Therefore, the President started the development of “micro-sized technologies” where he challenged the world’s smallest components. Miniaturization of such components has contributed to compact size, reduction in weight, and realization of super-thinness regarding videos and watches manufactured by major companies.
Steady management that does not depend upon drafts and recruitment of new employees “without exam on a first-come-first-served basis”
The company shifted its previous management to management that does not depend upon drafts, take an occasion to experience economic difficulty, and enhanced the financial characteristics. Simultaneously, the company invested in the cutting edge technical development in a positive manner. Additionally, the company adopts a unique method for recruitment of new employees “without exam on a first-come-first-served basis.” Thought this, young personnel can sufficiently exercise their own abilities. The company values such working environment, and enhances the motivations for technical development of the employees.
Anticipation of the future precision processing technologies at any time
The technologies that can manufacture a “1/1,000,000 g” gear are evaluated by domestic and international companies. And small precision components are used for a wide variety of domestic and international fields, such as automobiles, watches, and precision devices. Furthermore, the company aims at participation in optical device industry, and always groups for new technological fields regarding precision microfabrication. Immediate goal is to accept an order from NASA (National Aeronautics and Space Administration) in 10 years.

The company specializes in technical development and product development regarding ultrasound technology. The company progresses researches in the fields of environment, energy, and advanced medicine as the applied technology concerning ultrasound technology for the next generation. Development of the world’s first transistorized portable fish finder
In 1956, the world’s first transistorized portable fish finder was developed. Additionally, this is a sole company to develop the product as a fish finder maker that develops “piezoceramic” in-house as a core component so as to generate ultrasound.
Specializing in “ultrasound” and the development of the relevant technologies fish detector (TN-5700C) The company specializes in development of applied technologies regarding ultrasound since the development of a fish finder, and accumulates the development and know-how for elemental technology of 400 cases or more. And the company has exchanges with more than 40 research institutions such as universities, and cultivates new markets through the joint developments with companies in various industries.
All-round manufacturer of devices using applied technologies concerning ultrasound from a maker for fish finder
Ultrasound technologies have been applied to various fields. In the IT manufacturing industries such as semiconductors and flat panel displays, ultrasound cleaners and flowmeters apply. And devices for medical diagnostics should require safety, such as fetal diagnosis. Atomization devices that create healing spaces also apply. Thus, the ultrasound characteristics that are friendly to “human beings and environment” are utilized.
