Patent JP-H0355174-A (JP)
Title: Impact motion device
Inventor: YAMANAKA TAKANOBU
IPC: B25D9/04
Filed: 1989-07-25
Abstract: PURPOSE:To prevent generation of cavitation by fitting a cylindrical member with possibility of rising and falling outside that part of a piston which faces its lower chamber, wherein the cylindrical member falls together with a falling piston and separates from the piston, when it makes repulsion, and then rises again together with the piston. CONSTITUTION:When a valve element 10 lies at its lower limit and a piston 4 at the sunk position, an oil supply hole 12 is communicating to a lower chamber 7, and a middle chamber 6 is communicating to an oil exhaust hole 11, so that the piston 4 rises to compress the gas in the upper chamber 5. If the valve element is elevated by the oil pressure on the way of piston rising to put the lower chamber in communication with the oil exhaust hole through a communication hole in the valve element, the gas pressure in the upper chamber sinks the piston abruptly, which thus strikes the tool. When the piston has risen with the repulsive force at this time, a cylindrical member 21 outside the piston moves downward with inertial to eliminate abrupt variation in the capacity of the lower chamber, so that there is no abrupt pressure drop due to piston repulsion, and therefore the gas temp. in the pressure oil in the lower chamber will not grow, and no cavitation will be generated.

Title: Lubricating oil leakage preventer for turbo supercharger
Inventor: HIRABAYASHI YUUJI
IPC: F01D25/18
Filed: 1981-11-30
Abstract: PURPOSE:To prevent the leakage of a lubricating oil effectively by providing a pressure damping chamber between a back face and a shaft seal section and supplying the supercharge pressure in order to damp the exhaust pulse to be fed through a gap in the back face of an exhaust turbine. CONSTITUTION:An engine exhaust pressure pulse is directly transmitted into an exhaust path 4 in an exhaust turbine 1, and also functions to a gap 33 between said turbine 1 and a circular heat shielding board 20 provided in the vicinity of said turbine 1. Said pressure pulse is fed through a throttle section 24 between an opening 23 in said board 20 and a rotary shaft 3 then expanded i a pressure damping chamber 25 and transmitted to the outside of a shaft seal section 12. Since the pressure pulse is damped at the throttle section 24 and by the damping function in the pressure damping chamber 25, the pressure at the outside of the shaft seal section 12 is maintained approximately constant thereby the leakage of the lubricating oil through a minute gap between the shaft seal section 12 and the rotary shaft 3 can be prevented reliably.

Title: Counterflow preventive device for oil rotary vacuum pump
Inventor: NAKANO HIROMITSU
IPC: F04C25/02
Filed: 1981-12-02
Abstract: PURPOSE:To prevent counterflow of the oil which has filled the rotor chamber and thereby facilitate restarting, by such an arrangement that a disc is put in pressure contact with the end face of a bearing part for the shaft of rotor, when the revolving rotor is going to stop, in order to block an opening provided in the oil supply duct. CONSTITUTION:When the revolving rotor 2 is going to stop, the function to lift a disc 7 above the end face 9' of a bearing part for the shaft of rotor will become more active, and the disc 7 is put in pressure contact with the end face 9' by a coil spring 8 to block an opening provided in the oil supply duct 11. Consequently, no more oil will be supplied to the rotor chamber, and the oil filling this chamber is also driven out until the rotor 2 stops, so that there is no risk of oil's filling the rotor chamber which might cause a counterflow. Accordingly there is no such inconvenience any more as making impossible to restart because of the rotor chamber's being filled with oil.

Title: Tv camera fitting mount for microscope
Inventor: SHIBA OSAMU
IPC: G02B21/36
Filed: 1986-08-20
Abstract: PURPOSE:To obtain a sharp image all the time by engaging an eccentric dowel provided atop of an eccentric stepped machine screw for position adjustment with a mount which supports a TV camera and moving the mount by the rotation of the eccentric stepped machine screw. CONSTITUTION:When the TV camera 1 is fitted, the mount 2 which is engaged threadably with the TV camera 1 is fitted in the upper lens barrel 5a of a main microscope body 5. Then the eccentric stepped machine screw 3 is moved into the upper lens barrel 5a to fit the eccentric dowel 3a in the circumferential groove 2a of the mount 2. The eccentric stepped machine screw 3 is rotated in this state to rotate the eccentric dowel 3a eccentrically, thereby moving up and down the mount 2. Thus, the mount 2 is set the best position by the rotation of the eccentric screw 3 and then a setscrew 4 is clamped to fix the mount 2 to the main microscope body 5. Even when the setscrew 4 is loosened, the upward/downward movement of the mount 2 is restrained because the eccentric dowel 3a of the eccentric stepped machine screw 3 is fitted in the circumferential groove 2a of the mount 2, so the mount 2 is therefore held at the specific position.
