Title: Method of construction of concrete columnar body utilizing buoyancy
Inventor: TAKANO JIYOU
IPC: E02D23/08
Filed: 1980-01-24
Abstract: PURPOSE: To reduce hanging load and ensure safe execution by a method wherein buoyancy is worked and a concrete columnar body is sunk when the columnar body is built in a deep shaft.  
     CONSTITUTION: A shaft A is excavated up to fixed depth filling bentonite muddy water. A turret 1 in steel is assembled, flasks 2 are mounted, a jack 4 is installed to a beam 3 of the turret 1 in steel, and a hanging rod 5 is suspended from the jack 4 in a rise-and-fall-free shape. A lower end of the hanging rod 5 is fastened and fixed to a concrete floor block 6, and the concrete of a side wall 7 of a concrete columnar body B is placed on the concrete floor block 6 by utilizing the flasks 2. The concrete columnar body B is sunk into mixed water, working the buoyancy of bentonite muddy water to the columnar body with the placing of concrete and supporting the columnar body by means of the hanging rod 5. When the columnar body B is completely built, the muddy water is hardened or mortar is injected into a void between the shaft and the columnar body B.

Title: Fluid cylinder control circuit
Inventor: SUGIMOTO SHIYUN
IPC: F15B11/04
Filed: 1978-01-27
Abstract: PURPOSE: To eliminate the working delay of a piston in the case when a cylinder works in a reciprocative shape, by using the pilot pressure of a pilot check valve mounted in parallel with a throttle valve as pressure working to the other inside of the both side chambers of the piston.  
     CONSTITUTION: When initial working, the excess motion of a piston rod 24 can be prevented because pressure air flows into a chamber 21 through a throttle valve 17. When the piston rod 24 works in a reciprocative shape, there exists pressure air in a duct 13 and a pilot duct 22 when a change-over valve 12 is changed over, thus opening a check valve 18. Consequently, pressure air flows into the chamber 21 through the check valve 18 when the change-over valve 12 is changed over, thus eliminating working delay in the control of the cylinder.

Filed: 1993-01-20
Abstract: PURPOSE:To improve a stereoscopic sense and a sense of resolution of a reproduced picture by utilizing effectively a range of a luminance stage able to be expressed. CONSTITUTION:A gamma characteristic in an adjustment means 12 is changed by an operation means 14 as to the range of a lightness dominant on a screen by observing the entire screen of a picture display means 13 receiving three primary colors video signals generated by a reproduction means 11.

Title: Potential transformer apparatus
Inventor: HIGAKI SHIGEO
IPC: H02H7/05
Filed: 1983-01-20
Abstract: PURPOSE:To suppress the occurrence of ferro-resonance, by closing a switch by means of a signal from a detection control circuit which detects ferro-resonance thereby to connect a suppressed impedance component to a secondary circuit of a potential transformer only when ferro-resonance occurs. CONSTITUTION:When an electric shock is generated by opening of a breaker, an abnormal current with a peaked waveform flows as the primary current of a potential transformer 1. The peak value is about ten times as high as that in a stationary state. Therefore, the detected voltage also increases to a value larger than a preset value. A switch 7 is closed by a signal from a detection control circuit 8, so that a damping resistor R as a suppressed impedance component 6 is connected to a secondary circuit of the potential transformer 1. By the damping resistor R, the fractional harmonic vibration due to ferro-resonance is suppressed, therefore, no abnormal voltage is generated in the circuit of the potential transformer 1.
