摘要： A process for manufacturing a spool valve whereby a plurality of quenching processed collars are fitted to a shaft material so that the collars are arranged at predetermined positions on the shaft material. The collars have respective substantially central holes through which the shaft material extends. The diameter of portions of the shaft material is contracted in a vicinity of both opposite ends of each of the collars by rolling dies so as to cause plastic flow of a metal constituting the shaft material. Pairs of circular convex portions are then formed on outer circumferential faces of the diameter contracted portions of the shaft material. The circular convex portions each have an outer diameter larger than an inner diameter of the substantially central holes of the collars, and the circular convex portions are formed such that side faces thereof are in close contact with respective associated circular concave portions formed at both ends of the collars in a vicinity of the substantially central holes of the collars, whereby the collars are fixed to the shaft material.

摘要： A spool valve includes a shaft having plural small diameter portions formed at intervals along the shaft on a circumferential surface of the shaft. The small diameter portions have linear outer surfaces extending substantially parallel to an axis of the shaft. A collar to be mounted to the shaft has a substantially central hole defining an inner diameter of the collar and through which the shaft is passable for mounting the collar to the shaft. The collar has a length shorter than a length of the small diameter portions of the shaft, and a linear inner surface extending substantially parallel to the axis of the shaft and the linear outer surfaces of the small diameter portions. A pair of circular convex portions are integrally formed on outer circumferential faces of a corresponding one of the small diameter portions. The pair of circular convex portions each have an outer diameter larger than the inner diameter of the collar which is to be mounted to the shaft, and are spaced apart from each other by a distance substantially corresponding to the length of the collar. The collar is arranged between the circular convex portions so that side faces of the circular convex portions are in close contact with opposite side surface portions of the collar in a vicinity of the substantially central hole of the collar.

摘要： The present invention proposes an intake heating device of an internal combustion engine. The intake heating device has a hollow heater vessel comprising an inner pipe and an outer pipe between which an enclosed area is defined. For heating the inner pipe, a plurality of PTC elements are disposed in said enclosed area. The protection of the PTC elements from water, oil and the like is accomplished by coupling the inner and outer pipes hermetically and by embedding the lead members for applying voltage to PTC elements integrally in the outer pipe wall when it is being cast. For maintaining the fundamental function of the PTC elements, at least one of the lead members embedded in the pipe wall is formed in a tubular shape along which a through hole can be provided for allowing a certain amount of air to flow into said enclosed area.

摘要： A method of manufacturing a shaft having modified surfaces. The method comprises forming thread grooves on surfaces of a cylindrical-shaped base material for a shaft, continuously winding a length of wire in and along the thread grooves, and compressing a peripheral surface of the base material for the shaft with the length of wire wound and received in the thread grooves, in a direction of diameter reduction to perform plastic deformation of crests of thread ridges between the adjacent thread grooves or the crests and the wire to have the length of wire being fixed to and united with the base material for the shaft. The method improves the hardness of surfaces of a base material for a shaft in a relatively simple manner, and transforms properties of surfaces of the base material for a shaft to make the base material for the shaft applicable to other uses.
