Title: Masayoshi Asami: Inventor of a Wear-Resistant Hydrodynamic Bearing
Introduction
Masayoshi Asami is an inventor associated with Funabashi, Japan, and Canon Kabushiki Kaisha. His work includes an invention focused on improving the wear resistance and lubrication of hydrodynamic bearings.
Latest Patents
Asami is credited with 1 patent: “Hydrodynamic Bearing Structure, Hydrodynamic Bearing Apparatus, Method of Producing Hydrodynamic Bearing Apparatus, and Deflection Scanning Apparatus Using Hydrodynamic Bearing Apparatus.” The invention describes a shaft integrated with a rotary polygon mirror and fitted into a sleeve with dynamic-pressure-generating grooves. It improves the bearing surface by applying a chemical conversion film and an electrodeposition film containing lubricating filler, such as silicon-based resin or inorganic particles. The process offers a simpler alternative to plating and is designed to improve wear resistance and lubricity, including during low-speed rotation.
