Solenoid valve parts made of composite magnetic material

■ Composite Magnetic Material (Japanese Pat. No. 4136936)

Sumitomo Electric invented the composite magnetic material jointly with Sumitomo Electric Sintered Alloy Ltd. and Denso Corp. This product is used as the core of the electromagnet to attract the movable valve of the injector solenoid valve installed in a next-generation diesel engine. This engine is drawing public attention as a fuel-saving, low CO2 emission technology.

Since automobile engine components are exposed to high temperatures, fuel injection valves require high heat resistance. Conventional composite magnetic materials, which are made by depositing a heat insulating film on magnetic iron powder, cannot ensure sufficient heat resistance though they have excellent magnetic characteristics. To overcome the disadvantage of conventional magnetic materials, we conducted various investigations and studies and finally solved the problem by adding an extremely small quantity of high-temperature resistant resin and using die-wall lubrication compacting method. The composite magnetic materials made by our new process simultaneously exhibit high-temperature strength, high density, and excellent magnetic characteristics.

This product was awarded the prize for its large contribution to the promotion of science and technology and the expansion of related industries through fuel efficiency improvement and exhaust emissions reduction.

Optical data link

■ Pluggable Data Link (Japanese Par. No. 4470851)

The pluggable data link, which was developed by Sumitomo Electric after extensive research, is a photoelectric conversion module suitable for use in an optical communication system. This product was awarded the prize for its excellent heat dissipation characteristic and magnetic shielding capability with a low-cost, mass-producible structural design that simplifies insertion into/removal from communication equipment.

■ Air Cushion for Railroad Vehicles (Japanese Pat. No. 4331423)

The air cushion for railroad vehicles, which was developed jointly by Sumitomo Electric and Sumitomo Metal Industries, Ltd., was awarded the prize for its extremely long service life. In particular, the inner structure of the inner cylinder rubber seat has been improved to minimize wear attributable to contact with the diaphragm.
