Title: Kouji Tarumoto: Innovator in Engine Technology
Introduction
Kouji Tarumoto is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of engine technology, holding a total of 6 patents. His innovative designs focus on improving the performance and durability of engine components.
Latest Patents
One of Tarumoto's latest patents is for a slide contacting member and its production method. This invention involves a slide contacting member that is subjected to slide contact with a counter member. The member is created by applying a hard layer, such as chromium, onto a parent material. A high energy density laser beam is then used to irradiate the hard layer, forming concavities that retain oil during contact with the other member. The hard layer is finished with grinding after irradiation.
Another significant patent is for a rotor housing designed for a rotary piston engine. This rotor housing features improved gas sealing properties between the inner surface and apex seals mounted on a rotor. The inner surface is applied with a hard layer, such as chrome plating, while the areas surrounding the openings of plug holes are formed with softened areas that have lower hardness than the apex seals. This design ensures that if the softened areas deform, they will wear before the apex seals, preventing uneven wear and maintaining gas sealing integrity.
