Title: Driving power supply equipment for piezoelectric actuator
Inventor: NONAMI MITSUHARU
IPC: H01L41/09
Filed: 1991-07-05
Abstract: PURPOSE:To restrain fine vibration and voltage creep phenomena of a piezoelectric actuator, by installing a control means which turns off a chopper circuit when the charging voltage of a piezoelectric element reaches a specified voltage, and keeps the chopper circuit in the OFF state until a voltage applying command turns off. CONSTITUTION:Generated voltages of resistors R5, R6 on the earth side led out from signal terminals 12, 13 of a reversible chopper circuit 4 are inputted in a comparator 9 of a chopper driving circuit, and compared with a set voltage. A flip-flop 16 is arranged on the output side of the comparator 9. A charging current flowing in a piezoelectric element rises stepwise and then attenuates. On the contrary, the terminal voltage increases. Since a signal led out from the signal terminal 13 is a voltage proportional to a charging current, said voltage is compared with a voltage set value by a comparator 9. When the signal value is lower than or equal to the voltage set value, the flip-flop 16 turns off a switching transistor Tr1, and a pizoelectric actuator is cut off from a power supply.

Filed: 1982-09-24
Abstract: PURPOSE:To detect the position and speed of a body to be detected as a digital quantity at high resolution, by operating a PLL, which follows the operation of a rotor of a synchro by sine wave function operation continuously. CONSTITUTION:The output voltage of a control amplifier 50 is inputted to a V/F converter 60 and converted into a pulse signal of a frequency, which is proportional to the magnitude of the voltage. The pulse signal is counted by a frequency divider 70, and the result is inputted to an exciting circuit 80 as a digital signal, which gives the phase theta0 of an exciting signal. Then two phase exciting signals of Sintheta0 and Costheta0 are outputted and stator windings 11 and 12 of a synchronous machine 10 are excited. Thus a closed loop, wherein the signal is circulated, is constituted. By the circulating signal, the phase theta0-theta of the induced voltage of a rotor winding 13 of the synchro 10 is controlled so that the phase becomes equal to a position theta* of a reference signal of a reference generator 30. In the Figure, 20 is a phase shifting circuit, 40 is a phase comparator circuit, 90 is a position detecting circuit, and 100 is microcomputer.

Abstract: PURPOSE:To prevent a stock solution from penetrating into a solid discharge pipe, by opening the intake port of a discharge pipe for discharging a solid substance formed to the inner periphery of a basket toward the rotary direction of a basket. CONSTITUTION:A basket 7 is rotated to a b-direction at a high speed and a stock solution is supplied into the basket 7 from a solution supply pipe 15.

Filed: 1978-12-27
Abstract: PURPOSE: To provide a MOSFET which causes no parasitic capacity due to a p +  n + -junction without increasing the number of steps of masking and photo-etching.  
     CONSTITUTION: When forming an E/DMOS inverter, the polycrystalline silicon gate electrode 32 of an FETT 1  is annularly formed on an insulating film 40 around a source 22 -2  wherein the inside is a source and the outside is a drain 22 -1 . The drain 22 -1  makes contact with a p + -type channel stopper 23, while the source 22 -2  does not make direct contact with the stopper 23. Since the area of the source can be sufficiently reduced with respect to the lenght of the channel, parasitic capacity can be sufficiently reduced. The FETT 2  incorporates a gate 32 wherein the inside is a drain and the outside is a source. An electrode 39 is connected to the source, and an electrode 38 is connected to the drain. The parasitic capacity of the drain is similarly sufficiently reduced. Since the FETT 1  is annularly formed, certain displacement of a mask can be allowed actually if it is displaced to the degree that a punch through phenomenon may not occur. Thus, the load capacity can be remarkably reduced as compared with the conventional process to thereby enable high  speed operation of this semiconductor device.
