Title: Naruhiko Inayoshi: Innovator in Advanced Materials
Introduction
Naruhiko Inayoshi is a notable inventor based in Aichi, Japan, recognized for his contributions to advanced materials and engineering. With a total of two patents to his name, Inayoshi has made significant strides in the development of innovative solutions for various applications.
Latest Patents
Inayoshi's latest patents include a Pb-free bearing used for fuel-injection pumps and an insulated wire. The Pb-free bearing is crafted from a Cu—Bi based sintered alloy, which incorporates hard particles like FeP. This invention aims to suppress the flow of the Bi phase to a minimal level, ensuring that the contact between the Bi phase and hard particles remains low. The bearing contains 1 to 30 mass % of Bi and 0.1 to 10 mass % of hard particles, with the balance being Cu and unavoidable impurities. This design allows for sliding properties comparable to those of Pb-containing Cu-based sintered alloys. The insulated wire features a multi-layer insulating coating that includes a polyamine-imide-series resin underlayer, a polyimide-series resin intermediate layer, and a self-lubricating-type polyamide-imide-series resin overlayer. This construction prevents damage to the insulating coating during coil working under severe conditions, even when the coating is thin.
