IPC: H04N5/21
Filed: 1987-09-30
Abstract: PURPOSE:To attain waveform equalization without receiving effect of DC offset by cancelling the DC produced in an analog circuit system and then updating the tap gain. CONSTITUTION:A reference voltage from a reference voltage generator 111 is subtracted from a digital signal string by a subtractor 112 and the difference is equal to the DC offset caused by an A/D converter 2. UP/Down counters 106, 104 are counted up or down by a DC offset string comparated negatively or positively by a code discriminator 110, the count of the counter 14 is added to an input signal by an adder 103 to cancel the DC offset gradually. When the DC offset is sufficiently converged, a switch 115 is closed by an HIGH output of the counter 109 and the tap gain updating signal of a waveform distortion detection 6 is fed to a tap gain memory 5. Thus, the production of undesired tap gain due to the DC offset is prevented.

Abstract: PURPOSE:To reduce the variation of torque and improve durability by obtaining an optimum cylinder profile on the basis of the high/low pressure ratio and constituting the range of reduction of the springing-out of a vane from the increasing and reducing ranges for the drawing-back speed, thus specifying the joint point of the both ranges. CONSTITUTION:An optimum cylinder profile is obtained on the basis of the high/low pressure ratio, and the range (180 deg.<=theta<=360 deg.) where the vane springing- out amount reduces is constituted from the range A where the vane drawing- back speed increases and the range B where said speed reduces B. The turning angle thetab at the deflection point where he change form the A range to the B range occurs is set in the vicinity of the peak torque generation position, i.e., the turning-angle position thetaa where the pressure in the working chamber reaches a discharge pressure. Then, the vane springing-out amount is reduced, and the peak torque is reduced in the A range. Because of the presence of the above-described deflection point, the vane springing-out amount can be slowly reduced in the succeeding turning angle range, and the variation of torque can be reduced. With such constitution, the durability of the vane and cylinder can be improved.
