摘要:
A changeover valve unit for a power-assisted steering system includes input and output shafts arranged for relative rotation on aligned axes, a torsion bar interconnecting the shafts, a spool valve element surrounding the input shaft and arranged to be axially displaced in response to relative rotation of the shafts for controlling the supply of pressurized fluid to a hydraulic cylinder associated with the steering system, and a displacement mechanism for the spool valve element. The valve unit further includes an annular retainer member engaged with one end of the spool valve element to form an oil chamber, a compression spring assembled within the oil chamber to bias the spool valve element toward the displacement mechanism, and an annular orifice formed around the input shaft by means of the retainer member to permit the flow of fluid between the oil chamber and the interior of the spool valve element.
摘要:
A changeover valve unit for a power-assisted steering system includes input and output shafts arranged for relative rotation on aligned axes, a spool valve element concentrically assembled with the input shaft to be axially shifted in response to relative rotation of the shafts, and a sleeve-like valve casing surrounding the spool valve element to cooperate with the spool valve element for controlling the supply of fluid under pressure to a hydraulic cylinder associated with the steering system. A thrust plate is rotatably coupled at its inner periphery with the output shaft and secured at its outer periphery to the valve casing thereby to prevent rotation of the valve casing and to permit axial movement of the valve casing caused by displacement of the output shaft.

It is disclosed a dielectric element comprising a lower electrode, a dielectric layer, and an upper electrode which are provided on a substrate, in which at least one of the electrodes is a Pt layer, a Ru layer is used as a base layer for the Pt layer. In the fabrication of the dielectric element, the Pt layer is formed by electroplating, a photoresist pattern is used as a plating mask, and an Ru layer is formed as a seed layer. The present invention makes it possible to provide a dielectric element using Pt as an electrode material, that is capable of easily forming a Pt electrode having excellent electrical characteristics without generating voids or seams, that is capable of forming a fine pattern, and that does not occur contamination in a processing chamber, and a method for fabricating a dielectric element of having the characteristics mentioned above.

A novel anti-sunburn skin-care preparation, such as creams, foundations, milky lotions and the like, is proposed which contains, as the ultraviolet-absorbing and -shielding ingredient, a salt of ellagic acid with a polyvalent metal, e.g., calcium, barium and magnesium. The skin-care preparation is free from the problem of irritation and sensitization of human skin and exhibits excellent anti-sunburn effect with durability.
摘要:
A coating solution for use in the formation of a metal oxide film is described. It is composed of (a) a .beta.-diketone, (b) at least one element or compound selected from the group consisting of elements capable of forming complexes with said .beta.-diketone, salts of the elements and hydrolysates of alkoxides of the elements, and (c) an aprotic polar solvent. As an alternative, it is composed of a metal complex of a .beta.-diketone and an aprotic polar solvent.

A release system for a seat occupant restrained by a seat-belt in a vehicle can be operated either inboard or outboard. The system includes a mechanism for emergency-releasing a seat-belt retractor after the seat-belt retractor has been locked, and an emergency release control for the mechanism mounted on the vehicle body and having inboard and/or outboard operating terminals. According to this system, a rescuer can operate the system from outside the vehicle to release a stunned seat occupant, e.g. after a collision involving the vehicle and can quickly rescue the seat occupant.
摘要:
When a driver inserts a key into a cylindrical lock-type outside door switch and rotates it clockwise or counterclockwise, a slide door for an automotive vehicle is opened or closed automatically by motor power from the outside of the vehicle. Additionally, when the driver inserts the key into the outside door switch, and rotates it to an open position, the slide door is unlocked automatically before being opened; when the driver extracts the key from the outside door switch, the closed slide door is locked automatically. A motor is mounted on the slide door and a power supply is applied to the motor by means of a current collector. A pinion and rack are also mounted on the slide door to open or close the door. Such structure allows the slide door to be opened or closed manually or automatically.
