A sliding member (excluding that used for an image forming apparatus), which can maintain a satisfactory friction coefficient and reduce generation of a rubbing sound (noise) caused by a continuously sliding member, is provided. A component and a mechanical apparatus using the sliding member, and a method for reducing noise caused from a mechanical apparatus, are also provided. Additionally, a coating agent composition is provided for preparing the sliding member. The sliding member has a lubricating film contacting another member, wherein an arithmetic average roughness Ra based on JIS B0601 (2001) of a surface of the lubricating film is from 0.01-1.0 m, and the lubricating film comprises 100 parts by mass of a coat-formable resin binder (A) and 5 to 200 parts by mass of a solid lubricant (B).

A scroll compressor includes a first scroll member, a second scroll member, and an aerostatic thrust bearing. The aerostatic thrust bearing forms a layer of gas between the second scroll member and a fixed supporting member to support the second scroll member as the second scroll member rotates and/or orbits. Also disclosed is a method of supporting a rotating/orbiting scroll member in a scroll compressor. The method including supplying pressurized gas to an aerostatic thrust bearing such that a layer of gas is formed between the rotating/orbiting scroll member and a fixed supporting member.

The present invention relates to a low-friction member imitating shark skin and a manufacturing method therefor, the low-friction member implementing a structure similar to shark skin and having riblets by stacking, in layers, composite particles formed by attaching spherical particles on the surfaces of plate-shaped particles, and thus the low-friction member has excellent low-friction characteristics. The present invention comprises: a base plate; plate-shaped particles stacked in layers on the surface of the base plate in the form of scales; and a plurality of spherical metal lubricating particles having a size smaller than that of the plate-shaped particles, and coated on the surfaces of the plate-shaped particles, wherein the metal lubricating particles are arranged in the form of a bridge connecting the base plate and the plate-shaped particles, and the plate-shaped particles to each other.

A lubricant coating device preventing coating unevenness of lubricant powders is provided. The lubricant coating device includes a solid lubricant, a coating member and a film shaping member. The coating member in which first fibers composed of a material located on a positive polarity side and second fibers composed of a material located on a negative polarity side, on a triboelectric series with respect to the material of the solid lubricant are implanted, coats lubricant powders scraped off from the solid lubricant onto the image supporter. The film shaping member comes in contact with the image supporter and presses the lubricant powders onto the image supporter, to shape the lubricant powders into a form of a film. A scraping amount of the lubricant powders by the first fibers and a scraping amount of the lubricant powders by the second fibers are set to become substantially identical.

A method comprises inserting the fuel rod (4) through the spacer grids (14) aligned along an assembling axis (A) with passing the fuel rod (4) through a lubrication chamber (30) aligned with the spacer grids (14) such that the lubrication chamber (30) is passed through by the fuel rod (4) before the insertion of the fuel rod (4) through one of the spacer grids (14), and circulating a lubrication fluid containing a gas and a lubricant in gaseous phase and/or mist form in the lubrication chamber (30). The lubrication fluid is injected in the lubrication chamber (30) at a temperature strictly higher than ambient temperature, such that lubricant deposits or condensates in liquid phase with forming a lubricant film on an external surface of the fuel rod (4) that is being inserted through said one of the spacer grids (14).
