High-reliability wire wound resistors to be used for rockets and satellites

We have a history of more than 40 years as a wire wound resistor maker. Our high-reliability wire wound resistors are approved by JAXA, and are also used for rockets and satellites such as space satellites. The resistors are also used by Japanese and European car makers, and for power electronics, construction machines, railways, defense, etc. In our machining business, the resistors are used for the heating coils of high-frequency quenching devices used by car makers. Our philosophy is to manufacture by ourselves the production devices that we use, and thus we have developed technical capabilities by integrated production from parts designing to machining and assembly.

[Company strength]
We receive jobs from domestic and foreign leading major enterprises including major European makers and the three domestic major car makers at present. Our strategy is “three pillars (electronic parts, communications equipment and machining work) plus one”. We handle everything from product development to manufacture and sales by freely using our own techniques based on our philosophy of manufacturing by ourselves the production devices that we use. These comprehensive technical capabilities, combined with our business management strategy of safety, security and stability, are our strengths as an enterprise.

[Business description]
We started in 1973 as a factory specialized in wire wound resistors. Electronic parts have entered a new era due to the dramatic progress of electronic technology. Our high-reliability wire wound resistors are used in pioneering rockets and satellites of the Japan Aerospace Exploration Agency (JAXA), and are widely used in various other fields such as in-vehicle applications, power electronics, construction machines, railways, and defense. Our resistors are highly evaluated. In our machining business, our products are also used for the heating coils of high-frequency quenching devices used by car makers, etc.

Manufacture

[Strength of products/technologies]
Our high-reliability wire wound resistors, which are our core technology, are developed and designed in-house and offer such high reliability that they are used for rockets and space satellites with JAXA authorization. We have developed a new chip-type resistor mounted in a car, etc. to control electricity. This resistor is used to measure electricity necessary for driving the motors, power windows, etc. of a car or the like. We are improving our technical capabilities by integrated production including designing, machining and assembly of parts by ourselves on the basis of these core techniques.



[Representative's message]
Our management philosophy is that “As a member of the electronic machine and apparatus industry, we command a presence and contribute to society by freely using techniques to improve customers’ satisfaction”. With this policy, we will make progress toward the 22nd century by meeting emerging needs and conducting production development through industry-academia partnerships, and will enter the environmental energy field, in addition to our existing businesses. To achieve this, we will develop sales channels in various fields by actively participating in exhibitions, etc.

[Company structure for market development/overseas expansion]
We will participate in exhibitions, business negotiation meetings, etc. and grasp customers’ needs in various fields, in order to actively suggest new applications while leveraging our comprehensive technical capabilities and core technologies. We will develop an internal system to boost sales channels including major enterprises.

[Market share/Ranking]
Our products such as current sensor resistors for special uses and high-reliability resistors have large market shares.
