    摘要： A piston for an internal combustion engine of an automotive vehicle. The piston has a piston ring and a piston skirt section each of which has a sliding section in slidable contact with a cylinder bore section of a cylinder block in presence of a lubricating oil. The cylinder bore section is formed of eutectic or hyper-eutectic aluminum alloy. Additionally, a hard carbon thin film is coated on the sliding section of the piston and contains hydrogen atom in an amount of not more than 1 atomic %. Here, the lubricating oil contains at least one selected from the group consisting of ashless fatty acid ester friction modifier, ashless aliphatic amine friction modifier, polybutenyl succinimide, derivative of polybutenyl succinimide, zinc dithiophosphate, and derivative of zinc dithiophosphate.

    摘要： An engine piston-pin sliding structure includes a piston pin slidably engaged into a pin boss of an engine piston and having a base and a hard carbon coating formed on the base so as to define a sliding surface slidable over a bearing surface of the pin boss and a lubricant interposed between the sliding surface of the piston pin and the bearing surface of the pin boss. The hard carbon coating contains 25 atomic % or less of hydrogen, and the lubricant contains at least one of an ashless fatty-ester friction modifier and an ashless aliphatic-amine friction modifier.

    摘要： A self-drilling and self-extruding fastener having a constant cross section stem and a tapering end portion terminating in a sharp point. The stem is provided with a pair of screw threads of like configuration. The tapering portion is provided with a third thread which begins at the pointed forward end in a very steep lead angle which functions as a drilling portion and thereafter the lead angle decreases so that the third thread may function to extrude the metal surrounding a guide opening formed by the drilling portion. Depending upon the screw thread configurations, one or both of the screw threads cooperate with the third thread to further extrude sheetmetal surrounding the guide opening into a cylindrical bore, after which the screw threads self-tap into the wall of the cylindrical bore of the projection and thereby firmly grip the sheetmetal.

    摘要： A self-extruding fastener having a head provided with a cross groove, a stem having two screw threads and a tapering portion terminating at a sharp pointed forward end adapted to form a guide opening in a thin sheet of metal. A third screw thread generates in a position midway between said two screw threads and in a portion where the stem ends and the tapering portion begins, and extends to the pointed forward end, while the two screw threads disappear in the tapering portion. Therefore, the self-extruding fastener according to the invention comprises three sections, that is, two screw thread section, three screw thread section and one screw thread section.
