Latest Patents

Hayashi holds a patent for a fluid dynamic pressure bearing, motor, and recording medium driving device. This invention features an annular dynamic pressure generating face with a dynamic pressure generating groove. The design draws a working fluid toward a midway position in the radial direction from both the inside and outside of a thrust bearing plate when a shaft and housing rotate relative to each other. The dynamic pressure generating groove is strategically placed on the thickness direction end faces of the thrust bearing plate or on the inner surface of the housing. An inner groove section is located on the inner peripheral side of the dynamic pressure generating face and is recessed more than the dynamic pressure generating face in the thickness direction. Additionally, a through-hole extends through the thrust bearing plate, connecting to the dynamic pressure generating face, while a communicating cavity links the opening portion of the through-hole and the inner groove section. Hayashi's patent is a testament to his innovative approach to engineering challenges, with 1 patent to his name.
