Title: Corona discharger
Inventor: TSUCHIYA HIROAKI
IPC: G03G15/02
Filed: 1983-01-25
Abstract: PURPOSE:To eliminate the need for a periodic cleaning operation and to maintain a stable discharge characteristic for a long period of time by fixing a corona discharge wire or grid wire to an ultrasonic oscillator. CONSTITUTION:An ultrasonic oscillator 12 is attached to the U-shaped side wall of an insulating support base 11 of a corona discharger. One end of a corona discharge wire 14 is fixed to the oscillator 12 and the other end is connected via a connector 13 to the other insulating support base 11. When a copy signal is inputted, a photosensitive body starts rotation and an oscillating circuit 18 is operated by the signal from a timing circuit 20 and the oscillator 12 is oscillated by the output thereof to oscillate a corona discharger wire 10 in an arrow direction, thereby dislodging the foreign matter sticking on the wire 14. A high voltage transformer 10 is then operated by the signal from the circuit 20 to impress a high voltage on the wire 14 and to generate corona discharge, by which the surface of the photosensitive body is uniformly charged. The need for a periodic cleaning operation is thus eliminated and the stable discharge characteristic is maintained.

Title: Ink jet head
Inventor: YASUHARA MASATOSHI
IPC: B41J2/175
Filed: 1986-01-21
Abstract: PURPOSE:To enhance power efficiency to the injection of ink, by arranging a valve opened when the pressure of an ink pressurizing chamber is negative to at least the ink supply passage connected to the ink pressurizing chamber. CONSTITUTION:When voltage is applied to a piezoelectric vibrator 1, said vibrator 1 is bent and deformed to the direction shown by an arrow and pressurizes an ink pressurizing chamber 9 to generate pressure waves. The pressure waves are respectively propagated toward a nozzle outlet 8 and the rear of the pressurizing chamber 9. The pressure wave propagated to the nozzle outlet 8 pushes a vale 12 to close the connection port 13 communicated with an ink supply passage 10. When the application of voltage to the piezoelectric vibrator 1 is stopped, the piezoelectric vibrator 1 returns to the reverse direction and the ink pressurizing chamber 9 is brought to negative pressure. Hereupon, the valve 12 moves upwardly and the ink pressurizing chamber 9 gets communicated with the ink supply passage 10 through the connection port 13 and the ink reduced in the nozzle due to the injection of the ink is replenished. Therefore, pressure loss at the pressure feed time of the ink can be eliminated and the pressure generated by the piezoelectric vibrator or a heat generating element can be efficiently worked on the injection of the ink.

Title: Ultrasonic switch
Inventor: OKAMOTO MINEO
IPC: G01S7/521
Filed: 1979-01-31
Abstract: PURPOSE:To facilitate angle adjustment of transmitter/receiver by stepwisely rotating transmitter/receiver of reflective type ultrasonic switch to stepwisely change the gain of sending/receiving wave in a specified direction. CONSTITUTION:Transmitter/receiver 1 is mounted to the supporter 2 so as to be freely rotated. The rotation angle is stepwisely (3 deg.-5 deg. for one step) changed by rotary member 3. One step rotation changes the gain of transmitter/receiver in a specific direction in a definite quantity X'. This also changes two steps of amplifier gain by use of changeover switch. When adjusting the mounting angle of transmitter/receiver, the gain changeover switch of the amplifier for receiver output is changed so that (y) is made a little larger than normal operation gain; the transmitter/receiver is rotated step by step so that it is sequentially shifted from the direction of unrequired reflected wave arrival. In this manner, the level of unrequired reflected wave, if it becomes maximum, is still smaller than the operating level of ultrasonic switch, and therefore no error occurs to the ultrasonic switch.

Title: Analog comparator
Inventor: SHIBATA ATSUSHI
IPC: H03K5/24
Filed: 1978-02-01
Abstract: PURPOSE:To give the sample holding function to the sense amplifier by providing the constant current switch to the constant current source of the sense amplifier, and also to ensure draw-out the steady comparison output in a high speed. CONSTITUTION:The sense amplifier comprises transistors TrQ1-Q4 plus resistance R1 and R2. TrQ5 and Q6 form a differential switch, and TrQ7 functions as the current source for TrQ3 and Q4. When sampling pulse SP is applied to TrQ5, TrQ5  is turned on with TrQ6 turned off respectively. Here bias voltage V2 and resistance  R3 of TrQ7 are decided so as to satisfy the reversing conditions of the memory,  and thus the output voltage becomes V<+>-R.Is (Is: current flowing to TrQ8). While  no sampling pulse is applied, TrQ5 is turnned off with TrQ6 turned on each, and  the output voltage features V<+>-R1.Is. As a result, the current flowing to resistance  R1 and R2 becomes constant regardless of the presence or absence of the sampling pulse, also ensuring the constant comparizon output.

Abstract: PURPOSE:To miniaturize a device, to lighten in weight and to save energy to be required by operating a quick drive system and a slow drive system when the error between a command signal and a position feedback signal exceeds a threshold and when it is below he threshold, respectively. CONSTITUTION:The error between a command angle signal supplied to an input terminal 1 and the position feedback signal of an antenna 13, which is obtained from an angle detector 14, is applied as an angle error signal to an absolute value comparator 15 from an angle error calculator 2, and compared with the prescribed angle error DELTAtheta1 in absolute terms. If the angle error signal is great, the power amplifier 4 of the slow drive system 23 and an electromagnetic clutch 8 are turned off, and a normal or reverse drive command is outputted to the quick drive system 24 in accordance with the polarity of the angle error signal, thereby rotating the antenna 13 at a high speed. When the angle error signal reaches around the instructed value and becomes less than the error DELTAtheta1, the drive command to the system 24 is cut off, whereas the drive command is issued to the system 23. Thus the system 23 can precisely position the antenna 13.
