Latest Patents

Kokubu holds a patent for a "Method for manufacturing hydro dynamic bearing device." This method enhances the circumferential speed during the grinding of an axial member, which is a crucial structural component of the hydro dynamic bearing device. The technique effectively prevents centrifugal whirling, thereby improving both grinding efficiency and product quality. The axial member is supported at both ends by a pair of plate members, allowing for effective rotation around its axial center. The grinding process is optimized by supporting the outer peripheral surface of the axial part with a supporting member. Additionally, the plate member in contact with the flange part of the axial member features a roll-off part, and the contact area is elastically supported by an elastic member.
