    摘要: An odontotherapeutic hand piece is formed of a head portion, a handle portion connected to the head portion and a coupling portion arranged in continuation with the handle portion. A rotary member provided with turbine blades is accommodated in the head portion. The odontotherapeutic hand piece has a working medium conduit, which is arranged in an internal space of the coupling portion and is detachably engaged with the coupling portion for supplying a working medium to the odontotherapeutic hand piece. The head portion, the handle portion and the coupling portion are made of a material which permits integral molding. The head portion, the handle portion and the coupling portion are integrally joined together.

    摘要: A dynamic bearing device allows production of a smaller housing at low cost and suppresses ion elution from the resin portion to thereby maintain cleanliness in the dynamic bearing device and exert a desired bearing performance. A dynamic bearing device 1 is equipped with a bearing sleeve 8 fixed to the inner periphery of the housing 7, and a rotary member rotatable relative to the bearing sleeve 8 and the housing 7, in which the rotary member is supported in the radial direction and the thrust direction in a non-contact manner by a dynamic pressure action of a lubricant fluid generated in a bearing clearance. The housing 7 is formed by injection molding of a resin composition containing polyphenylene sulfide (PPS) as the base resin and PAN type carbon fibers as a filler.

    摘要: An object is to reduce manufacturing cost of a housing, and enable to disuse an adhesive in fixation portions between a housing and a bearing sleeve and the like. A housing 7 is made of resin material, which comprises a liquid crystal polymer (LCP) as crystalline resin blended with carbon nanotubes in a blending ratio of 2 to 35 vol % as a conductive filler, by injection molding. A bearing sleeve 8, which is inserted into the inner peripheral surface 7c of the housing 7, is secured to the housing 7 by ultrasonic welding.
