Filed: 1988-09-17
Abstract: PURPOSE:To contrive the improvement of safety in a line pressure control by providing a pressure relief part, switching the control to a feedforward control from a feedback control when a line pressure exceeds an upper limit value, in a pressure regulator valve. CONSTITUTION:A pressure regulator valve 17 supplies the amount of a line pressure PL from a variable displacement pump 10 exceeding a predetermined value to a feedback control mechanism (control cylinder) 24 as the feedback pressure from a port 17d, performing a feedback control of the line pressure. Here in response to a rapid change of modifier pressure PM, when the line pressure PL exceeds an upper limit value of the feedback control, the valve 17 lowers against a spring 20, connecting a pressure relief part 17f to partly communicate with a port 17b, closing the port 17d, switching the feedback control to a feedforward control and cutting an overshoot of the line pressure. Thus while ensuring responsibility of the control to vibration of the line pressure, the line pressure control of safety can be attained.

IPC: G03B9/08
Filed: 1983-12-08
Abstract: PURPOSE:To eliminate the influence of bound, and to execute exact exposure control by applying a sine wave voltage by which a peak level coincides with the operating end point of a light shielding curtain, to an electrostriction element. CONSTITUTION:The sine wave signal from an oscillator 11 goes to a positive potential sine wave signal through a non-inversion amplifier 13a and it is supplied to a gate 14. This gate 14 is controlled by an open pulse generating circuit 20 to which a sine wave from the oscillator 11 passing through a differentiating circuit 12a and a comparator 12b to a ground level is applied, and the sine wave by which a peak level coincides with the opening end of a light shielding curtain charges a capacitor 17 through the gate 14. Subsequently, the charging voltage of the capacitor 17 is applied to an electrostriction element 1 for opening the light shielding curtain, and an opening speed of opening end of the light shielding curtain is reduced to the minimum. With regard to closing of the light shielding curtain by a closing pulse generating circuit 30, gate 16, etc., too, the closing speed of the closing end is reduced to the minimum in the same way. Accordingly, the generation of bound by a resonance, etc. of the electrostriction element is prevented, and the exact exposure control can be executed.
