Title: Hisashi Yasui: Innovator in Gasket Technology
Introduction
Hisashi Yasui is a prominent inventor based in Tokyo, Japan, known for his contributions to gasket technology. With a total of four patents to his name, Yasui has made significant advancements in the design and functionality of gaskets used in engine components.
Latest Patents
One of Yasui's latest patents is a metal laminate gasket with an engaging device having curved edges. This innovative gasket is formed from first and second metal plates that laminate together. The first plate features at least one hole designed to receive an engaging projection from an engine part, along with a series of engaging and non-engaging portions that define the hole. The engaging portions have curved inner edges that create an imaginary hole smaller than the engaging projection's diameter. The second plate corresponds with the first, ensuring a secure fit when placed on the engine part. This design prevents the gasket from disengaging from the engine part, enhancing reliability.
Another notable patent is a protecting member for a gasket, which is utilized between two engine parts. This member includes a spring situated around a bolt, providing predetermined pressure when the bolt is tightened. The spring absorbs excess outward force, reducing pressure changes on the gasket and preventing creep relaxation of the sealing means. This innovation significantly improves the durability and performance of gaskets in engine applications.
