Title: Water level difference type ball tap
Inventor: MATSUURA NOBUYUKI
IPC: F16K31/26
Filed: 1990-02-26
Abstract: PURPOSE:To prevent occurrence of water hammer by making the pressure receiving area of a piston larger than that of a discharge valve, and by forming a diameter enlarged part in a cylinder section so that the piston and the cylinder section fall in a sealed condition when the valve is opened, and the sealed condition is released when the valve is opened by a predetermined degree. CONSTITUTION:A water discharge valve 15 receiving a water supply pressure in a valve opening direction, and a piston 21 for receiving the same in a valve closing direction are unified by means of a valve linkage 20 so as to obtain a valve mechanism which is linked to a float 33 which is operated in association with a variation in the water level. The pressure receiving area of the piston 21 is made to be larger than that of the water discharge valve 15, and when the valve is closed, the piston 21 and a cylinder section 13 fall into a sealed condition by means of a seal ring 23. A large diameter part 11 is formed in the cylinder section 13 so that the seal ring is released when the valve is opened by a predetermined degree. As a result, it is possible to prevent useless opening and closing operation of the valve port caused by wave motions at the water surface which cause the float to vertically move.

Title: Thyristor power supply controller
Inventor: SUZUKI SHIYOUJI
IPC: G05F1/565
Filed: 1982-03-26
Abstract: PURPOSE:To eliminate easily a ripple with software without a filter of hardware, by adding an average value output operating part to the shortest time response controlling part of a lower-level computer. CONSTITUTION:An average value number indicating the number of operation outputs to be averaged and outputted is set to an average value output operating part 12. The target value from an upper-level computer and the feedback quantity from a current detector 6 are taken into the shortest time response controlling part of the lower-level computer. The shortest time control operation is performed on a basis of taken-in data so that an optimum current is flowed to a magnetic field coil. If a plasma current exciting signal of a control interruption signal does not exist, the number of outputs which is set to the operating part 12 are averaged, and the operation result is stored in an operation result table and is outputted. If the plasma current exciting signal exists, the current operation result is outputted without executing the average value output operation.

Title: Muting circuit
Inventor: EBI JUNSUKE
IPC: G11B20/02
Filed: 1990-02-28
Abstract: PURPOSE:To reduce the number of terminals to be used for the formation of an IC and to contract a mounting area by charging a capacitor when a power supply switch is ON and discharging the capacitor at the OFF of the capacitor to make a switch element conductive. CONSTITUTION:When the power supply switch 2 is turned on, the capacitor 15 is charged with electricity, transistors(TRs) 21, 24 are turned on and the switching element 28 is turned to the conductive state. When the switch 2 is turned off, the charged electricity of the capacity 15 is discharged, TRs 12, 18 are turned on and the element 28 is made conductive. Thereby, a signal (noise) from an input terminal 26 is allowed to flow into the earth side and a noise tone from a speaker is not discharged, so that only the capacitor is used for the muting circuit 50, the number of terminals to be used for the formation of an IC are reduced and the mounting area is contracted.

Title: Brake actuator
Inventor: MATSUMOTO YUKIO
IPC: B60T8/26
Filed: 1992-02-03
Abstract: PURPOSE:To provide a brake actuator which is capable of improving a feeling of speed reduction by simple constitution. CONSTITUTION:A liquid pressure control valve 19 for connecting and 7 disconnecting an output oil chamber 8 connected to a rear wheel side brake cylinder to and from an input oil chamber 9 connected to a brake master cylinder, is provided, and a shaft 22 which is driven by a motor 24 to advance or retract a piston 5 is provided. By operating the liquid pressure control valve 19, the liquid pressure rise on the rear wheel side is restricted at a smaller rate than the liquid pressure rise on the front wheel side, and thus the braking performance offering a good balance of both the front and rear wheels can be obtained. The capacity of the output oil chamber 8 can be enlarged by advancing or retracting the piston 5 to prevent lock of the rear wheel. Since the function of the liquid pressure control valve and the anti-lock braking function can be fulfilled by simple constitution, and the actuator is provided with both the functions, the operating limit becomes high, and thus a feeling of speed reduction can be improved.

Title: Magnetic recording and reproducing system
Inventor: MAEDA MIYOZOU
IPC: G11B5/09
Filed: 1981-03-31
Abstract: PURPOSE:To record and reproduce with high density, by setting a readout frequency of a readout head higher than threshold frequency of detection width limited by pole width of the head. CONSTITUTION:Readout frequency of a readout head of a magnetic recording and reproducing device provided with a magnetic medium, a recording and readout head, and a reproducing means of a readout signal is set higher than threshold frequency of detection width limited by pole width or slit width of the head. In this state, when reproducing, only an object information is reproduced from in the readout signal in which adjacent information has been mixed, by the reproducing means. Accordingly, even when recording density recording in the medium exceeds width of the head, a recording data can be demodulated and reproduced, and recording and reproducing can be recognized with high density without reducing the pole width or the slit width.

Abstract: PROBLEM TO BE SOLVED: To make it possible to generate a relatively high differential voltage across a 1st and a 2nd signal lines and precisely amplify it, by providing a first stage input circuit with a pre-charge circuit for pre-charging both signal lines to an external power supply voltage. SOLUTION: A latch-enable signal generation circuit is provided, which generates latch-enable signal LEB to make H level to 3.3V equal to an external power voltage VCC and to make L level to 0V.

Abstract: PURPOSE:To reduce an orthogonal shaft-type slant face nutation gear mechanism in its size by disposing a slant conical roller shaft on an orthogonal plane of a shaft so as to convert the driving and oscillation of the nutation gear to the rotation of a slant conical roller shaft. CONSTITUTION:In an orthogonal shaft-type single gear, V-groove 7 is disposed on the outer peripheral portion of an orthogonal plane (Y-Y') of a shaft passing the center of oscillation of a nutation gear 2, and a cone 6 is fixed to a slant shaft 5 at the same angle as a slant angle SIGMA of a slant shaft in such a manner as to be rotatable at the position of the axis (Y-Y') tilted from the center O of oscillation. Accordingly, the slant shaft 3 is turned in a designated direction by rotation of orthogonal shafts S2, S2' to oscillate nutation gears N2, N32, so that regular rotary gears N11, N44 engaged with gears N2, N32 can be forced to make nutation. Thus, a small-sized and strong orthogonal shaft-type single gear can be attained.
