    摘要： A bearing mechanism eliminates the need for lubricating oil, is capable of generating enough radial dynamic pressure even in lower-speed regions, and yet can be easily surface-machined for the generation of radial dynamic pressure and manufactured with low cost. In at least either one of an outer circumferential surface 2a of a first member 2 or an inner circumferential surface 3a of a second member 3 (hereinafter, referred to as roughened surface), the two circumferential surfaces being opposed to each other with a bearing gap G therebetween, dot-like minute dips and bumps are formed dispersedly, by which the surface is roughened so that its center-line mean roughness is controlled within a range of 0.1 &mgr;m-1.0 &mgr;m. With this arrangement, since enough radial dynamic pressure can be generated at a relatively low rotational speed, time duration of a dynamic-pressure insufficiency upon a start-up or halt of the rotating mechanism is shortened so that members in the bearing part can be made less liable to wear.

    摘要： Provided are: a separator material for a fuel cell, in which a uniform first Au-plated layer having a thickness of 0.5-4 nm is formed on one surface of a metal thin plate and a uniform second Au-plated layer having a larger thickness than that of the first Au-plated layer is formed on the other surface of the metal base material, wherein the covering rate of each of the cross-sections of the first Au-plated layer and the second Au-plated layer is 80% or more as observed on a transmission electron microscope, and which can have excellent corrosion resistance even when the thicknesses of the Au-plated layers formed on the surface of the base material are small, and can be produced at reduced cost; and a separator for a fuel cell and a fuel cell stack, each of which is produced using the separator material.
