Latest Patents

Shimizu holds a patent for a dynamic bearing device. This device allows for the production of a smaller housing at a low cost. It also suppresses ion elution from the resin portion, thereby maintaining cleanliness and ensuring desired bearing performance. The dynamic bearing device features a bearing sleeve fixed to the inner periphery of the housing. A rotary member is rotatable relative to the bearing sleeve and the housing. This rotary member is supported in both the radial and thrust directions in a non-contact manner by the dynamic pressure action of a lubricant fluid generated in the bearing clearance. The housing is formed by injection molding of a resin composition that contains polyphenylene sulfide (PPS) as the base resin and PAN type carbon fibers as a filler.
