Abstract: In a method for molding a laminated assembly comprising a resin core member, and a surface skin member either partly or entirely placed over the surface of the resin core member, the dimensional precision of a part of the surface skin member involving a high rate of extension is improved, and the cushioning property and the surface quality of this part are avoided from being impaired. An approximately molded portion is defined in a part of the surface skin member involving a relatively high rate of extension during the vacuum molding process using a vacuum molding die assembly, and the thus molded surface skin member is mounted on the upper die for mold press forming with a gap defined between the approximately molded portion or an unmolded portion and the associated die surface.

Abstract: In a method and die assembly device for molding a laminated assembly comprising a resin core member and a surface skin member covering a part of the surface of the resin core member, the shifting and creasing of the surface skin member is avoided, the molding precision is increased during the mold press forming process, and the external appearance of the assembly is improved.

Abstract: One of the internal key telephone sets coupled to a key telephone apparatus capable of automatic call distribution operates as a supervisor and other operate as agents. Under the automatic call distribution, the statuses of the agents and their number are stored in a memory. The stored statuses of the agents are informed to the supervisor. Each key telephone set has a display unit. When one of the key telephone sets operates as the supervisor, the informed statuses and their number are displayed on the display unit of the supervisor. With identification data of a specific agent, the status of the specific agent is displayed on the display unit of the supervisor. To operate one of the key telephone sets as the supervisor and other the agents, first, a password is entered from one of the key telephone sets. The input password is compared with a first reference password for the supervisor and with a second reference password for the agents.

Abstract: A solenoid valve for a antilock brake system comprises an electromagnetic coil part disposed on a housing, and a valve function part clearance-fitted in the electromagnetic coil part and hermetically received in a bore of the housing.

Abstract: A unit comprises a valve housing having a bottom portion; and a plurality of electromagnetic valves standing on the bottom of the valve housing. Each electromagnetic valve includes a coil which is housed in a housing structure. A cover member is put on head portions of the electromagnetic valves. A bolt extends from the cover member to the bottom portion of the valve housing to bias the cover member toward the bottom portion of the valve housing thereby to tightly fix the electromagnetic valves to the valve housing. A printed-circuit board is positioned above the cover member. Bracket portions for supporting the printed circuit board extend upward from the housing structure toward the printed-circuit board while keeping away from a lateral end of the cover member. Conductive lines are embedded in each bracket portion to provide an electric connection between each coil and the circuit of the printed-circuit board.

Abstract: In an arrangement having a plurality of solenoid valves disposed between a housing and a housing cover, the cover being attached to the housing by bolts, collar members are disposed around the bolts, and between the housing and the housing cover.

Abstract: A pressure control device for a hydraulic braking system of an automotive vehicle is provided with a master cylinder for pressurizing hydraulic fluid according to a braking action of a driver. A wheel cylinder for applying braking force to a wheel is communicated with the master cylinder through a main passage. An accumulator is connected to the main passage. A rotating condition of the wheel is detected by a detector and is outputted as a signal indicative of the rotating condition of the wheel. A hydraulic pressure controller is arranged to control the wheel cylinder hydraulic pressure when the detector detects one of a lock condition and a slippage condition. The hydraulic pressure controller is communicated with the main passage. A switching device is arranged to stop the communication between the master cylinder and the hydraulic pressure controller, and open the communication between the accumulator and the hydraulic pressure controller when the detector detects the slippage condition in acceleration.

Abstract: A hydraulic pump of the rotary vane type comprises a first throttle bore and a second throttle bore disposed in parallel between a pressure chamber of the pump and a delivery passage, and a variable flow throttle valve is provided which is responsive to a difference between a vane back-up pressure and a pressure within the delivery passage to vary an opening degree of the first throttle bore.

Abstract: A rotary-vane pump has a pump outlet, a pressure chamber of the pump, a flow control valve, and a throttle disposed between the pump outlet and the flow control valve. According to the present invention, the throttle is formed by an insert which is disposed in a pressure passage between the pump outlet and the flow control valve. Specifically, the pressure passage is disposed between the pump outlet and the pressure chamber, and the insert is hollow cylindrical and has an axial bore having one axial end portion disposed on the pressure passage. The insert is disposed in the pressure passage at an angle approximately 90.degree. in relation to the inflow direction of pressure medium in the passage.

Abstract: A vane pump is disclosed, which comprises a body structure defining a space which has mutually opposed surfaces; a cam ring tightly disposed in the space; a rotor having a plurality of radially extending vane mounting grooves and rotatably disposed in the cam ring having both sides thereof slidably contacting with the opposed surfaces of the body structure; and a plurality of vanes slidably disposed in the vane mounting grooves in such a manner that heads of the vanes slidably contact with an inner surface of the cam ring. In the invention, the rotor is formed at at least one side thereof with a throttle groove to which bottom portions of the vane mounting grooves are exposed.

Abstract: In a variable displacement vane-type rotary compressor, a rotational displacement of an adjust member relative to a front member fixedly closing a front end of a cam ring varies a compression starting point of a rotary vane in a working chamber formed in the cam ring. The front member is formed with an induction port and a bypass port, and the adjust member is formed with a bypass recess. The induction port and the bypass recess are in communication with each other in the working chamber irrespective of a position of the vane under all of the rotational displacement of the adjust plate to establish a communication between the induction port and the bypass port in the working chamber irrespective of the position of the vane when the bypass port overlaps with the bypass recess.

Abstract: A Langmuir-Blodgett ultrathin membrane is constituted of polyfumarate having a degree of polymerization of 20 to 10,000. The polyfumarate is obtained by polymerizing fumarate represented by the general formula of: ##STR1## wherein at least one of R.sub.1 and R.sub.2 represents a bulky hydrocarbon group such as a branched alkyl group, a cycloalkyl group or a substituent thereof, a fluorine-substituted hydrocarbon group, a hetero atom-containing hydrocarbon group or a silicon-containing group.
