Filed: 1982-09-27
Abstract: PURPOSE:To improve the equalizing performance of a waveform equalizer using a transversal filter, by using a section different in shaped waveform at each incoming of a digital waveform as a reference waveform. CONSTITUTION:An output of the transversal filter comprising an operating circuit 17 and a tap gain memory 18 is inputted to a level discriminating circuit 20, where the level is discriminated and the waveform is shaped.

Abstract: PURPOSE:To simplify change of forward speed of a piston rod by constituting that at the beginning of operation, pressure oil is received by an auxiliary action plane with a small area and then, resistance is imposed on a piston rod and pressure oil is received by a main action plane with a large area when a high-pressure valve device is opened. CONSTITUTION:In operation, first, pressure oil from a hydraulic pump is supplied to an auxiliary hydraulic chamber 5 formed in a piston rod 3 through an oil supply passage 6 and the piston rod 3 is moved to the right. At this time, as the pressure receiving area of an auxiliary action plane 5a is small, the piston rod 3 is advanced at high speed. After that, when the piston rod 3 collides with the work or the like and oil pressure in the chamber 5 rises, this raised oil pressure is transmitted to a high-pressure valve device 7 and pushes down a steel ball 7a against a spring 7b, so that the valve device 7 is opened. Accordingly, pressure oil flows to a main hydraulic chamber 4 through the valve device 7, and the piston rod 3 is advance with large output and at low speed by receiving oil pressure on its large pressure receiving plane.

The oil hydroulic cooling tube discharges a function of curbing a  revolving flow of oil within a thrust collar 1, in addition to its original function  of cooling oil. Since the oil hydraulic cooling tube is not placed on the outer  periphery of the thrust collar 1 in this way, the outside diameter of an oil tank  8 can be made smaller. Also, it becomes possible to provide a window 10 facing  all static boards 3. A spring support 4 need not be rotated and piping to thrust  up the spring support 4 will become unnecessary. Also, the distance between the  static board 3 and the outer periphery of the oil tank 8 becomes shorter to  facilitate pull out of the static board 3.
