Abstract: Disclosed is a connecting rod bearing for crankshafts having a pair of semi-cylindrical bearings. Circumferential grooves (CG) on the bearing inner surface extend from each circumferential end toward the circumferential center within a maximum circumferential angle of 45 degrees and divide reduced wall thickness region into two sections. Axial grooves communicating with the CG are provided along abutted ends of the bearings. Circumferential length of the CG is larger than that of the reduced region. Depth of the CG becomes gradually smaller from the end toward the center. Width of the CG is not smaller than one-quarter of a diameter of lubricant-oil outlet of internal lubricant-oil passage in a crankpin and less than the diameter. Cross-sectional area of the CG is larger than that of the axial grooves at a connection portion thereof.

Abstract: In a slide member in which an overlay is provided on a slide receiving surface of a base member, the overlay is formed by attaching a mixed solid lubricant on the slide receiving surface of the base member. The mixed solid lubricant is made by mixing a large amount of hydrogen containing solid lubricant which contains a large amount of hydrogen, and a small amount of hydrogen containing solid lubricant which contains a smaller hydrogen amount than the large amount of hydrogen containing lubricant. Thereby, a lubricant absence region where the solid lubricant is absent in a thickness direction is formed on the slide receiving surface of the base member after sliding, and an oxidized portion where the base member is oxidized is formed in the lubricant absence region.

Abstract: In a tool holder, when oil supplied via an oil supply passage and an oil introducing passage reaches an atomizing space, the oil is atomized by an air flow of carrier gas consisting of compressed air, and then water supplied from a water supply passage and a water introducing passage is formed into a water drop in the atomizing space by an air flow of oil containing compressed air to generate the water drop with oil film in which the oil film is formed on a surface of the water drop. Since the water drop with oil film is supplied to a work piece through a top nozzle and an in-tool passage, the water drop with oil film is generated at an extremely close location to a tool, and therefore, responsiveness when supplying the water drop with oil film to the work piece can be enhanced.

Abstract: In an electrode for an electric double layer capacitor of the present invention, the peak value of particle size distribution of graphite particles added to a conductive adhesive is in a range of 2.6 to 3.2 μm, not less than 100,000 dimples having a largest outer diameter in a range of 4 to 10 μm and a depth in a range of 4 to 15 μm are formed on the surface of the collector sheet per 1 cm2, and the occupied area of the dimples to the entire surface area of the collector sheet is not more than 50%. By determining the saponification value of polyvinylalcohol which is used as a binder component of the conductive adhesive in a range of 90.0 to 98.5, adhesiveness of the collector sheet and the electrode forming sheet is improved. Furthermore, by substituting H atoms contained in the polyvinylalcohol with Si atoms, adhesiveness of the collector sheet and the electrode forming sheet can be further improved.
