Title: Fumio Yoshida: Innovator in Dynamic Pressure Technology
Introduction
Fumio Yoshida is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of engineering, particularly in the development of innovative technologies that enhance mechanical performance. With a total of 7 patents to his name, Yoshida's work reflects a commitment to precision and functionality.
Latest Patents
Yoshida's latest patents include a shaft with grooves for dynamic pressure generation. This invention involves a resist printed on the areas where the dynamic pressure generating grooves are to be formed on the curved surface of a shaft core member. After hardening the resist through baking, hard electroless plating is conducted to create a plated layer equal to the depth of the grooves. The removal of the resist results in a shaft with highly precise dynamic pressure generating grooves, ensuring that the dynamic pressure during rotation remains stable and free from fluctuations. Another notable patent is the crosspiece supporting pad in structural construction. This pad features a resilient member with concavely curved surfaces and a pair of rigid members with convexly curved surfaces that mate with the resilient member. This design provides sufficient strength to support a crosspiece in expansion joints while effectively absorbing displacement due to live loads.
