Filed: 1993-06-16
Abstract: PURPOSE:To make the rotating motion of a recording medium stable by providing a limit means measuring a consecutive time of dropout and revising a signal from a dropout detector when the consecutive time reaches a predetermined time. CONSTITUTION:A dropout compensation circuit 5 is provided with a detection time limit circuit 54 limiting a consecutive time of an 'H' level switching signal from a dropout detector 53. When the detector 53 keeps an output of an H level switching signal, the circuit 54 measures a consecutive time of the switching signal based on a reference synchronizing signal from a reference synchronizing signal generator 62. When the measured time reaches a predetermined pulse of a reference horizontal synchronizing signal, the level of the H level is revised into an L level and the result is outputted to a changeover switch 51. Thus, when a dropout takes place, the level fluctuation of a normal video signal outputted from a 1H delay line 52 is set within a predetermined range and the instability of drive of a recording medium 1 due to level fluctuation is avoided.

Abstract: PURPOSE:To reduce the pressure loss by selectively feeding the pressure of a power steering circuit and the pressure of a discharge pipe to a capacity control valve as the pilot pressure with a selector valve, and pilot-operating the capacity control valve with the differential pressure between both pressures. CONSTITUTION:When there is no loading and no load is applied to a loading circuit 21, a selector valve 50 feeds the pressure P3 of a power steering circuit to a capacity control valve 80 as the feed pilot pressure P2. The position of the capacity control valve 80 is held by the differential pressure between P3 and the discharge pipe pressure P1, the pump oil quantity 35 is automatically adjusted, and the flow is maintained.

Title: Phase shifting circuit
Inventor: FUJIMOTO HIROZO
IPC: H02P6/06
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctioning caused by high-frequency signals and to enable surface phase shift operation, by shaping the output of a charge pump filter circuit by a Schmitt trigger circuit, and correcting the quantity of shifting which is lacking when it is performed only by the charge pump filter circuit, with a delay circuit after that. SOLUTION: Waveform shaping is performed by receiving with a charge pump filter circuit 12 a signal from a counter-electromotive force detecting circuit 1 for motors which detects the counter-electromotive force of a motor directly, smoothing noise generated in the output of the counter-electromotive force detecting circuit 1 for motors, and making the input hysteresis voltage width of a Schmitt trigger circuit 13 larger than an amplitude voltage generated by a chattering signal. Moreover, the quantity of shifting which is lacking when performed only by the charge pump filter circuit 12 is corrected by a delay circuit 14, and is outputted as a digital signal F. Accordingly, malfunctioning caused by high-frequency noise signals is prevented, and sure phase shifting becomes feasible.
