Title: Kazuya Sato: Innovator in Fluid Dynamic Bearings
Introduction
Kazuya Sato is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of fluid dynamic bearings, holding a total of 2 patents. His innovative work has advanced the technology used in various applications, particularly in spindle motors and disk driving apparatuses.
Latest Patents
One of Kazuya Sato's latest patents is a fluid dynamic bearing manufacturing method. This method involves reducing the pressure inside a chamber where a bearing is arranged. By lowering the pressure in both the oil tank and the chamber below atmospheric pressure, a minimal or no pressure difference condition is achieved. This allows lubricating oil to be supplied from the oil tank into the chamber using a liquid transfer pump. The design ensures that gas does not dissolve into the lubricating oil, which has been deaerated by the pressure reduction. Additionally, the driving force of the liquid transfer pump facilitates easy control over the amount of lubricating oil supplied.
Another significant patent is for the production method of fluid dynamic bearings, which includes a shaft aligned along a center axis and an annular portion that expands radially outward. The design features a sleeve that supports the shaft and annular portion in a rotatable manner, with a lubricating fluid interposed between them. This innovative bearing design also includes a solid lubricating film on the outer edge, enhancing its functionality.
