Title: Pump displacement controlling circuit
Inventor: HORIUCHI TAKESHI
IPC: F04B49/06
Filed: 1978-03-17
Abstract: PURPOSE: To permit an actuator to be stopped with small loss of power by controlling the discharging pressure and displacement of pump to the necessary minimum value in the return motion stopping area of the actuator by the use of a special pilot valve.  
     CONSTITUTION: When an actuator 29 reaches the return motion end to increase the pressure in a return motion supply line 30, a spring offset type pilot valve 22 of 3-port hydraulic, direction controlling valve system built in a third diversion line 21 of main flow line 20 is switched by the pressure signal acting through a signal circuit 31. And the third diversion line 21 is connected to a second controlling cylinder 26 through a normally open path 25 of high pressure controlling valve 24. Thus the loss of power in actuator can be minimized by removing almost the displacement of a variable pump 32 in the relatively low pressure area to stop the actuator 29.

Title: Simulation method for pll
Inventor: BABA ATSUSHI
IPC: H03L7/06
Filed: 1994-02-03
Abstract: PURPOSE:To sharply shorten simulating operation time by converting the phase information of a real circuit into a voltage value and adding the voltage value to a simulation circuit. CONSTITUTION:A phase comparator and a frequency divider constituting a PLL are constituted of a voltage controlled voltage source and a voltage controlled oscillator constituting the PLL is constituted of a voltage controlled current source and a capacitor to obtain a simulation circuit for the PLL. Simulation is executed by impressing a voltage value converted from the phase information of a real circuit for tone PLL to the simulation circuit. Namely the phase information of the real circuit is treated as voltage in the simulation circuit, so that the time width of simulation analysis can be set up independent of the period of a reference signal and the simulation circuit is operated like a current, simplifying simulating operation. Thereby the simulating operation time can be sharply shortened.
