Title: Resin made piston cup
Inventor: HIROBE YOSHIAKI
IPC: F16J1/02
Filed: 1985-10-18
Abstract: PURPOSE:To improve the response characteristic of an oil hydraulic pump and its reliability, by providing a fall-stop protrusion, brought into contact with a cylinder internal peripheral surface, in the periphery of a base part in a resin made piston cup so as to prevent it from falling. CONSTITUTION:The point end of a seal lip part 4 in a resin made piston cup 2 is formed into a little larger contour, taking an effect of sealing action with a cylinder 1. While the peripheral surface of a base part 3 in the resin made piston 2 is opposed to the internal peripheral surface of the cylinder 1 slightly providing a clearance, while a peripheral protrusion 6 is formed in one part of said peripheral surface of the base part 3. In this way, the resin made piston cup 2 is prevented from falling by the peripheral protrusion 6, and an oil hydraulic pump, using said piston cup, can improve a response characteristic and reliability.

Title: Braking liquid pressure sealing device for vehicle
Inventor: MAEHARA TOSHIFUMI
IPC: F16K31/06
Filed: 1985-10-18
Abstract: PURPOSE:To enable designing of an electromagnet device substantially independently of the intensity of a sealed liquid pressure, by a method wherein abutment with the valve seat of a moving valve body moved in one way by means of an electromagnetic force causes sealing of a brake liquid pressure on the brake device side. CONSTITUTION:A valve is formed with a valve body 10a of a balance piston 10 and a valve seat 9. A balance piston 10, which functions to seal a brake liquid pressure and release it and is moved, is governed by effectiveness and ineffectiveness of the spring force of a set spring 11 and a magnetic attraction force, produced through excitation of a solenoid 7, irrespective of a liquid pressure state on the upper stream side and the downstream side of a valve part. Thus, in order to maintain the stop of a vehicle, even when a high liquid pressure is sealed in consideration of, for example, a stop on an upward slope, a surplus burden is prevented from being applied on an electromagnet. This enables the use of an electromagnet device which is small on the whole and has a small capacity.

Title: Proximity switch
Inventor: NIIMI CHIKA
IPC: G01S7/48
Filed: 1992-08-06
Abstract: PURPOSE:To improve the sensitivity for magnetic flux on a detecting surface, expand the detecting surface, and extend the detecting area of an object by connecting the winding ends of a plurality of detecting coils in series to each other. CONSTITUTION:An oscillating circuit is formed by mutually connecting the winding ends of coils 4, 5 arranged in parallel to each other, mutually conforming the magnetic flux directions on a detecting surface to promote the magnetic flux so that the sensitivity is improved. The oscillating frequency or reduction in amplitude is detected by a signal processing circuit to detect an object. Thus, the change of magnetic flux caused by the access of the object is enlarged to improve the sensitivity, and the detecting area can be extended. Since the magnetic fluxes are canceled to each other on the reverse side of the detecting surface, external effects can be minimized.
