Title: Norikazu Muneda: Innovator in Sliding Bearings and Magnetic Core Technology
Introduction
Norikazu Muneda is a prominent inventor based in Mie, Japan. He has made significant contributions to the field of engineering, particularly in the development of sliding bearings and magnetic core technology. With a total of 4 patents to his name, Muneda continues to push the boundaries of innovation.
Latest Patents
Muneda's latest patents include advancements in sliding bearings, bearing apparatus, and image forming apparatus. His work aims to provide a non-oil-impregnated sliding bearing that exhibits superior low friction, effectively suppressing the increase of shaft temperature during continuous use. The sliding bearings are designed to support rotation shafts on the inner surface of cylinders in a rotatable manner. Each sliding bearing is formed from a molded member of a non-oil-impregnated resin composition that does not contain oil. This innovative resin composition includes an injection-moldable ultrahigh molecular weight polyethylene resin as the base resin, a polytetrafluoroethylene resin as an additive, and an acicular inorganic filler with a Mohs hardness of 3 or less. The composition consists of 65 vol % or more of the ultrahigh molecular weight polyethylene resin, 5-25 vol % of the polytetrafluoroethylene resin, and 1-20 vol % of the acicular inorganic filler.
Another notable patent involves a powder for a magnetic core, which includes a soft magnetic metal powder and an insulating coating film that covers the surface of the soft magnetic metal powder. The insulating coating film is formed from an aggregate of crystals obtained by cleaving a layered oxide, specifically a swellable smectite-group mineral.
