Filed: 1982-11-17
Abstract: PURPOSE:To increase grasping of piston rod and to shorten the sleeve by fitting a resilient sleeve to a piston rod while moving a wedge chip provided at the outside of resilient sleeve. CONSTITUTION:When there is no pressure in an operating position holder 4, a hydraulic cylinder 1 is standstill through fastening between a resilient sleeve 16 and the outercircumference of piston rod 3. Upon expansion/shrinkage of hydraulic cylinder 1, pressure oil is fed to oil paths 19-21 where a wedge tube 13 and wedge chip 12 are disengaged by the pressure oil in the oil path 21 while a sleeve 16 is expanded by the pressure oil in the oil paths 19, 20. In order to hold the operating position of hydraulic cylinder 1, pressure oil is fed through oil path 22 into a plunger tube 10 to move the wedge tube 13 toward the wedge chip 12 to press strongly against the sleeve 16 while at the same time oil feeding to the oil paths 19-21 is stopped to release expansion due to resiliency of sleeve 16.

Abstract: PURPOSE:To reduce noise due to multi-path disturbance by detecting the multi- path disturbance by another control circuit at a time other than the processing time of a control circuit, and switching a receiving antenna, allowing to prolong the observing period and to eliminate the deterioration in the S/N of the clock frequency. CONSTITUTION:A control circuit 30 provided separately consists of a detecting circuit 31 detecting the multi-path disturbance, driving signal generating circuit 32 forming an input of the driving circuit of an antenna switching circuit 3, and a processing time deciding circuit 33 deciding a processing time width T1. An output of the circuit 32 generates a positive pulse by setting an output of the circuit 33 to zero level in the processing time T1 and to 1 level at a time other than the processing time, every detection of the multi-path disturbance only at a time other than the processing time. This signal becomes one input to a signal coupling circuit 34, and since the input from a signal coupling circuit 13 is at zero level in this case, the output of a 1st driving circuit 14 is inverted at a time other than the processing time by a trigger signal by the output of the circuit 32. Thus, the switching of the receiving antenna is attained to the detection of multi-path disturbance in and outside of the processing time in such a way.
