Abstract: PURPOSE:To shorten a frame resynchronization time at the time of the phase shift of received data by providing two frame synchronism protecting circuits which differ in the number of times of step-out detection, and selecting and outputting frame pulses of one circuit which synchronizes earlier when a step-out state is entered. CONSTITUTION:The two frame synchronism protecting circuits I and II which differ in the number of times of step-out detection are provided behind a frame detecting circuit 3 and if a frame step-out occurs, frame pulses of one frame synchronism protecting circuit which synchronizes earlier are selected by a selector 6. Consequently, the frame pulses generated by the circuit which finishes resynchronization earlier at the time of the step-out are outputted as frame pulses for synchronous operation, then the frame resynchronization time from the occurrence of the step-out to the completion of resynchronization can be shortened.

Filed: 1986-06-20
Abstract: PURPOSE:To enable prevention of collision of a piston with a cylinder wall, by a method wherein a pressure in a space, where a piston moving in a cylinder is moved, is regulated. CONSTITUTION:By means of a position signal inputted from a position detector 35 to a control device 36, the average position of a piston 25 is detected. When the average position of the piston 25 is displaced upward based on a set average position, a valve 33 and further a valve 34 are closed to increase a pressure in a space 39. When the piston is lowered to the average position, the opening of the valve 34 is fixed. Reversely, when displaced downward, the valve 34 is closed to lower a pressure in the space 39, and further the valve 33 is opened. As noted above, the pressure in the space 39 is controlled through control of the openings of the valves 33 and 34, and the average position of the piston 25 is always adjusted to a set position. This constitution prevents the piston 25 from collision with a container 20 and a suction valve 29.
