摘要： At least a race (1c) of a blank (B) for forming a bearing raceway member is hardened by heating. The race (1c) thus hardened by heating is finished to predetermined precisions. Subsequently, the race (1c) is roller burnished for hardening the race (1c). The blank (B) is formed from a steel for bearing manufacture or a carbon steel for machine structural use. The blank (B) formed from the steel for bearing manufacture is subjected to the roller burnishing, thereby achieving a hardness of HRC65 or more at a surface of the race (1c), and a center-line average roughness Ra of 0.1 μm or less at the surface of the race (1c). The blank (B) formed from the carbon steel for machine structural use is hardened by the roller burnishing, thereby achieving a hardness of Hv800 or more at depth of at least 0.2 mm from a surface of the race (1c). Where cutting by turning is adopted as the finishing process, the surface of the race (1c) is finished to a center-line average roughness Ra of 0.35 μm or more and then the race (1c) is subjected to the roller burnishing, thereby achieving a center-line average roughness Ra of 0.25 μm or less and a compressive residual stress of 1000 MPa or more at depth of at least 0.2 mm from the surface thereof. Where cutting by turning or grinding is adopted as the finishing process, the race (1c) is subjected to the roller burnishing, thereby achieving a center-line average roughness Ra of 0.15 μm or less at the surface thereof and a compressive residual stress of 1000 MPa or more at depth of at least 0.2 mm form the surface thereof.

摘要： In an ignition device for an internal combustion engine, comprising a spark plug made to carry out an electric discharge between an center electrode and an earth electrode and an ignition coil having a primary winding and a secondary winding for supplying a high voltage to the spark plug, notch portions are made in a ceramic spool on which one of the primary and secondary windings is wound and projecting portion are made in an insulating-resin-made holding member into which connector terminals are incorporated, with the projecting portions being engaged with the notch portions. The engagement of the projecting portions and the notch portions prevents the connector terminals from moving with respect to the ceramic spool in circumferential directions of the ceramic spool during terminal connection work. This solves the problems in that, in the case of the employment of a ceramic spool, because difficulty is encountered in insert-molding the connector terminals in the ceramic spool, the connector terminals can move with respect to the ceramic spool during terminal connection work for the connection of the winding to the connector terminals to cause poor terminal connection workability.

摘要： A spark plug for an internal combustion engine is provided which is equipped with a tip protrusion disposed on a top of a hollow cylindrical housing of the spark plug. The spark plug also includes a center electrode retained in a porcelain insulator disposed inside the housing and a ground electrode is joined to the housing so as to form a spark gap. The tip protrusion serves to direct a flow of gas to be ignited by a spark produced in the spark gap and is shaped to have a radial width extending in a radial direction of the housing and a circumferential width extending in a circumferential direction of the cylindrical housing. The radial width is greater than the circumferential width. This enhances the efficiency in guiding the flow of gas toward the spark gap.

摘要： A bearing is provided which can be sufficiently processed by a usual NC grinding machine, and attain a life period that is substantially equal to that of a bearing having a theoretical crowning shape which is derived from the elastic contact theory, even when the bearing is used in a portion to which a heavy load or a high torque load is applied. As means for realizing such a bearing, a generating line of a rolling surface of a roller or a raceway surface of an inner or outer race is divided into a plurality of zones, and the shape of the generating line is approximated to a special curve shape which is theoretically derived, by a plurality of circular arcs which are contacted with each other on the border line between the corresponding zones. Therefore, it is possible to obtain a roller bearing which can be practically used, and which can attain a life period that is substantially equal to that of a bearing having an ideal crowning shape.
