IPC: F16J3/06
Filed: 1985-05-23
Abstract: PURPOSE:To prevent a diaphragm from coming off from a coupling section and to facilitate the manufacture thereof, by forming a plurality of circumferential grooves in the outer surface of an inner cylinder in the diaphragm coupling section thereof and by fastening the diaphragm with a fastening ring in an elastically compressed condition. CONSTITUTION:A plurality of circumferential grooves 21a are formed in the diaphragm coupling section 21 of an inner cylinder 2 within a diaphragm actuator. Each circumferential groove 21a has opposing inclined surfaces (x, y) having a press-fit opposing angle alpha and coming-off opposing angle beta with the relation such as, alpha<45 deg.<beta, and a diaphragm 1 is fastened to the grooves by a fastening ring 3 so that the diaphragm is elastically compressed by a predetermined amount.

Title: Displacement enlarging device
Inventor: KUNIMOTO ETSUO
IPC: F16K31/02
Filed: 1994-04-28
Abstract: PURPOSE:To improve responsiveness by suspending solid fine powder of sand, ceramics, etc., in a liquid, in a displacement enlarging device setting up large/ small diametric pistons opposed to each other in a cylinder, filling between both the pistons with liquid, and bringing a piezoelectric element or magnetostrictive element into contact with the large diametric piston. CONSTITUTION:A liquid, suspending solid fine powder 9 of sand, ceramics, etc., in oil and water, is placed in a cavity 5. When a solid is mixed in the liquid, in the case of pressurizing this liquid, by compressing almost not the solid but a liquid part, the mixed liquid displays apparently low compression ratio. In a viscosity object having ordinary fluidity, rigidity of two times or more the single liquid is obtained. When voltage is applied to a layer built piezoelectric element 2, a large diametric piston 3 in contact therewith compresses the liquid in the cavity 5, to drive a small diametric piston 4 by a pressure rise of the liquid. Since the liquid in the cavity 5 is not compressed like oil, an enlarging part of good responsiveness can be constituted of the large/small diametric pistons.

Title: Electronic watch
Inventor: UEDA JIYUN
IPC: G04C3/14
Filed: 1978-09-12
Abstract: PURPOSE:To reduce the price and size by constructing both a rotor rotation and irrotation detector and a magnetic field detector of the same construction. CONSTITUTION:P-type MOSFET gates 10 and 12 and N-type MOSFET gates 11 and 13 constitute a drive inverter. The output terminals 18 and 19 of the drive inverter are connected with a coil and further with a detecting resistor 16 through gates 14 and 15. On the other hand, the connection 20 of the resistor 16 is connected with the input terminal of a binary logic element 17 having a preset threshold value. At the timing when drive pulses are impressed upon the coil, only the gates 10 and 13 are conductive so that a current flows from a power source VDD by way of a passage indicated at arrow 21. If only the gates 13 and 14 are rendered conductive, a closed loop 22 containing the coil 3 and the resistor 16 is constituted. And the induced voltage of the coil 3 appears in the connection 20. Here, by setting the voltages of the detector 17 in two ways, i.e. at a low level for the magnetic detection and at a high level for the rotor detection, it is possible to detect the influences from the external magnetic field and the induced voltage due to the vibrations of the rotor in a high sensitiveness.
