摘要： A rubber composition made of a diene rubber having such excellent properties as heat resistance and mechanical strength and organopolysiloxane or fluoropolymer as a lubricating substance. The lubricating substance may contain isocyanate or cyanate groups, which will react with the hydroxy groups which exist on the surface of a filler usually applied to the diene rubber, thus securely keeping the lubricating substance in the molecular structure of the composition. A liquid diene polymer containing hydroxy groups and having a good compatibility with the diene rubber may be further added to the composition so that its hydroxy groups will react with the isocyanate or cyanate groups in the lubricating substance.The liquid diene polymer may contain epoxy groups instead of hydroxy groups, whereas the lubricating substance containing such functional groups as amino, carboxyl, hydroxy or mercapto groups so that the epoxy groups in the former and the functional groups in the latter will react with each other. The composition may further contain an isocyanate compound containing isocyanate groups, with the liquid diene polymer containing hydroxy groups. In this arrangement, the hydroxy groups in the liquid diene polymer will be replaced with the isocyanate groups, which in turn will react with the functional groups in the lubricating substance.

摘要： A weld line formed by injection molding of a sealing member is formed at a circumferential position out of deepest portions of axial grooves, which form thinned portions of the sealing member (optimally, in a region of a cylindrical surface between the axial grooves in a circumferential direction). Thus, the sealing member is prevented from being provided with parts having locally markedly low strength, and hence damage to be caused by press-fitting is prevented.

The fluid dynamic bearing device supports a shaft member (2) radially in a non-contact fashion by a dynamic pressure action generated in a radial bearing gap between an outer peripheral surface of the shaft member (2) and an inner peripheral surface (7a) of a bearing member (7), and is composed of the shaft member (2), the bearing member (7), a cover member (8), and a seal member (9). The shaft member (2) is inserted into an inner periphery of the bearing member (7), and an opening at a lower end thereof is sealed by the cover member (8). The seal member (9) is attached to an opening at an upper end of the bearing member (7), forming a seal space (S) between itself and the outer peripheral surface of the shaft member (2). Dynamic pressure grooves (G) of radial bearing portions (R1 and R2) are formed in an inner peripheral surface (7a) of the bearing member (7) by molding.

摘要： A fluid bearing device which enables cost reductions and prevents static electricity charging. A bearing sleeve is secured inside a housing, and a shaft member is inserted inside an inner peripheral surface of the bearing sleeve. A lubricating oil dynamic pressure effect is used to generate pressure within a bearing gap between the inner peripheral surface of the bearing sleeve and an outer peripheral surface of the shaft member, thereby supporting the shaft member in a non-contact manner in the radial direction. An axial end portion of the shaft member contacts a housing bottom portion, enabling conductivity between the two members, and the housing is made of a conductive resin composition containing added carbon nanofiber with a volume resistivity of 106 Ω·cm or less.

摘要： Improvements in a finger strip for copying machines are proposed. The finger strip made of a heat-resistant resin is coated with a fluorinated polyether polymer to improve lubricity and antistickiness. High adhesion strength between the coating and the substrate and very thin coating help to eliminate the problems of poor separation and jamming of paper.
