Title: Tetsuo Ohinata: Innovator in Gasket Materials and Fuel Cell Technology
Introduction
Tetsuo Ohinata is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the fields of gasket materials and fuel cell technology. With a total of 3 patents to his name, Ohinata's work reflects a commitment to innovation and engineering excellence.
Latest Patents
One of his latest patents is a gasket material comprising a metal plate and a fluorine rubber layer having a specific Vickers hardness. This gasket material includes a metal plate and a fluorine rubber layer with a Vickers hardness of 15 to 30 N/mm. It is designed to maintain a sealing bead surface at high surface pressure without altering the engine block design and the gasket design. Additionally, it can absorb flange surface roughness, which is a primary purpose of the rubber layer.
Another significant patent is for a separator for fuel cells and the process for producing the same. This invention provides a separator that contains a flat plate member, a gas passage-side member, and a cooling water passage-side member. The gas passage-side member has passages for passing a reactant gas, while the cooling water passage-side member has passages for passing cooling water. The two members are formed from different conductive resin compositions, ensuring that the difference in thermal expansion coefficients is minimal.
