Title: Hydraulic servo device
Inventor: FUJITA YASUHIKO
IPC: F16H61/04
Filed: 1979-07-26
Abstract: PURPOSE:To decrease the rapid increase of a servo-hydraulic pressure and provide a smooth control over a speed transmission in the hydraulic servo device for use in an automatic transmission of an automobile by a method wherein an air ventilation hole not causing oil to be flowed therethrough is made at an end wall of a hydraulic chamber and an air reservoir is formed in the hydraulic chamber. CONSTITUTION:When the hydraulic oil is flowed into a release hydraulic chamger  B, at first the oil is apt to flow out from the clearance S as the surface of the hydraulic oil is raised. The oil is hardly flowed out due to high viscosity of the oil if  the clearance shows a space having a value of 15mu to 25mu. Further, when the surface of the hydraulic oil is raised, the ball 17 is moved up to close the air ventilation hole 16a. Lastly, when the air ventilation hole 16a of the upper plug 16 is  closed, the upper portion in the hydraulic chamber B becomes a closed space, so  that the air in the space of the upper portion may act as an accumulator to decrease  an increasing speed of the hydraulic pressure.

Title: Control method for air-conditioner
Inventor: YAMAMOTO MASATO
IPC: F25B13/00
Filed: 1991-04-02
Abstract: PURPOSE:To enable restarting of a compressor after OFF of running of a compressor, to prevent the damage of the compressor, and to reduce the generation of noise, offensive to the ear, of a refrigerant during OFF of running of the compressor. CONSTITUTION:A four-way valve is left in an ON-state during a given time (Ta, for example, three minutes) starting from an OFF time of running of the compressor of an air-conditioner and until a given time (Tb, for example, two minutes) starting from an OFF time of running elapses. Thereafter, the four-way valve is repeatedly brought into an ON and an OFF state for a given time (Tc, for example, 50 seconds). Only during an ON-state, a refrigerant flows from the high pressure side to the lower pressure side, a differential pressure between the pressure of a heat exchanger on the inner side and the pressure of a heat exchanger on the outdoor side is gradually balanced, and the four-way valve is returned to an ON-state after a lapse of the given time Tc. As noted above, by balancing a pressure difference, a compressor is brought into a state to be capable of restarting, the damage of the compressor is prevented from occurring, and the generation of noise offensive to the ear during OFF of running of the compressor is suppressed.

Title: Tracking control circuit for rotary head type tape recorder
Inventor: TAKI TETSUYA
IPC: G11B15/467
Filed: 1987-04-20
Abstract: PURPOSE:To realize the stable tracking control by applying limitation to the tracking error signal higher than a prescribed level when the tracking control is carried out with the offset secured by the prescribed value. CONSTITUTION:When the tracking control is carried out with the offset given by the prescribed value to a track to be traced, a limiter circuit 12 is used so that the tracking error signal higher than a prescribed level is suppressed down to a fixed level. In other words, the output of an operational amplifier 11 is limited by the circuit 12 consisting of an operational amplifier 13, a variable register 14 and a diode 15 so that the lower limit error voltage value has the S-curve characteristics. Then this limited output of the amplifier 11 is supplied to a capstan motor control part for execution of the tracking control, that is, the tape drive control is carried out so that the limit error signal voltage is equal to zero. Thus it is possible to prevent an excessive tracking error signal produced when a rotary head is offset by the prescribed value and to perform the stable tracking control in an offset state.
