Abstract: An oil control valve has a cup shaft and a plunger. The cup shaft and the plunger have a projection and a recess to provide a male-female joint. The male-female joint provides contact points which can reduce lateral offset and inclination. The projection and the recess provides two or more force transmitting points from the plunger to the cup shaft, when the projection and the recess are inclined with each other. The force transmitting points are located about the central axis of the spool in a distributed manner.

Abstract: A valve includes a valve housing and a linier solenoid. The linier solenoid includes a cylindrical yoke and is coupled with the valve. An open end of the yoke is crimped to a flanged crimping receiving part provided along an outer periphery of the valve housing, so that the linier solenoid and the valve are coupled together. The open end of the yoke includes a plurality of notches provided in a circumferential direction of the yoke, and the plurality of notches defines a plurality of crimping pieces. Each of the plurality of crimping pieces includes a large part and a small part. The large part is located on a base side of the each of the plurality of crimping pieces and has a larger circumferential width. The small part is located on an tip side of the each of the plurality of crimping pieces and has a smaller circumferential width.

Abstract: In a solenoid valve, a boss portion is formed integrally with an attracting portion of a stator core at an outer peripheral side of the attracting portion. The boss portion has a tapered outer peripheral surface and a tapered inner peripheral surface. A plunger has a communication passage, which extends through the plunger generally along a central axis of the plunger.

Abstract: A spiral cutter for use in an electric razor in which the lower end of a band-shaped blade made of elastic material is embedded in the peripheral surface of a body with the band-shaped blade torsionally deformed. The spiral cutter is manufactured by the steps of: mounting a band-shaped blade made of an elastic material in a body molding die with the band-shaped blade torsionally deformed; molding a base; and removing a molded product from the body molding die after the body is molded.

Abstract: A push-button switch locking device for use in an electric appliance including a casing, a push-button and a switch. The device includes a sliding knob which is mounted on the casing so as to be slid in a direction at right angles to a direction of depression of the push-button, and a locking piece which is provided so as to be operated upon displacement of the sliding knob such that the push-button is locked and unlocked, respectively.

Abstract: A washable electric shaver comprising a water-tight housing having a drive motor therein and a switch mounted thereon, and a shaving head. The shaving head has a stationary shear plate cooperable with a movable shear element which, when driven by the drive motor, oscillates in engagement with the stationary shear plate to cut hairs of a beard. The shaving head has a pair of end openings located on respective sides of the movable shear element and adapted to be selectively opened and closed by respective lateral lids which are normally biased so as to close the end openings. The shaver can be washed by allowing a flush of water to flow from one of the end openings to the other through the interior of the head when the lateral lids are in opened positions.

Abstract: An electric shaver of a vibration type which includes a shaver head portion or upper casing having a movable blade and a screen blade, and arranged to be tilted with respect to a main casing of the shaver, and a trimmer unit adapted to be projected from the main casing in a direction opposite to the tilting direction of the shaver head portion for facilitation of trimming of hair.
