Title: Protection system for switching element driving circuit
Inventor: SHIMOKAWABE TOSHIAKI
IPC: H02M3/00
Filed: 1989-06-05
Abstract: PURPOSE:To evade the effect of stray capacitance of a voltage dependency resistive element being a load of a switching section by adding 2 diodes to the driving circuit. CONSTITUTION:A short-circuit current of a FET 64 flows to a high voltage power supply 4 via a fuse 51, a diode 32 and a varister 41 without being supplied to a +Vcc terminal 101 because of the presence of a diode 33, the fuse 51 is blown out after a prescribed time to protect a switching section 100. On the other hand, the stray capacitance of the varister 41 is charged up to +Vcc via a diode 33 at the time of normally operating and when a driving signal voltage of +V is supplied to a gate of the FET 64, the stray capacitor of the varister 41 is not charged through the diode 32. Furthermore, when driving signal voltage of -V is applied to the gate of the FET 64, the charge in the stray capacitor of the varister 41 is not discharged because of the presence of the diode 32. Then, the effect of the stray capacitor of the voltage dependency resistive element is prevented.

Filed: 1981-09-10
Abstract: PURPOSE:To totally reduce the time of data transmission, by starting the transmission of data blocks, without waiting for a response signal to the data block in succession to the end of the transmission of one data block. CONSTITUTION:Before a data block 4 which is a confirming signal or a retransmissiont request signal to a data block 3 reaches a transmission side 1, the transmission of the next data block 5 is started prior to the end of the transmission of the data block 3, and the transmission of a data block 7 in sucession to the end of the transmission of the data block 5 is strated. If the data block 4 is a retransmission request to the data block 3, the data block 3 is retransmitted from the data block 7. The end of transmission is performed at the transmission side 1 after the confirming signal to all the data blocks are waited. If there is any data block not receiving either the confirming signal or the retransmission request signal for a prescribed time or over, the retransmission of the data is performed.

Title: Non-touch switch apparatus
Inventor: YANAGI YASUHIRO
IPC: H01H13/00
Filed: 1991-06-15
Abstract: PURPOSE:To prevent erroneous input due to unconscious input. CONSTITUTION:Hollow places 23 are formed in the surface of sites corresponding to respective non-touch switches 1 of an insulator 20. The sensitivity of the non-touch switches and the distance between the insulator 20 and a touch face 21 are so set as to react the non-touch switches 1 by touching the hollow places 23 by a finger tip. The input by a finger with a will touches the lower part of a hollow place 23 and thus a non-touch switch 1 reacts. The input with a large surface area by the shoulder, back, etc., of a human body 22 without will does not touch the lower part of a hollow place 23, so that a non-touch switch 1 does not react. Consequently, error input by unconscious input is prevented.

Title: Optical axis adjuster of head lamp

IPC: G05B11/36
Filed: 1983-08-06
Abstract: PURPOSE:To make a retractable head lamp cease at accurate positions by driving a motor turn it up or down until the optical axis thereof reaches the high or low position and redriving the motor to raise the lamp to the low position from any overrun. CONSTITUTION:When an inclination angle indicating switch 40 is turned to right by one step so as to turn down an optical axis, a selector 43 comes into contact with the points 43N and 431 and another selector 44 comes into contact with the points 443 and 444 so that a transistor TR3 is turned off and transistors TR4 and TR1 are off. A motor 10 is then driven reversely until the selector SG of a feedback switch unit 12 makes contact with a contact point S2, causing a head lamp to stop. If the selector SG overruns to a contact point S3, the transistors TR3 and TR4 are on and off, respectively so that a transistor TR2 becomes on. The motor 10 is therefore turned clockwise until the selector SG makes contact with the contact point S2. At the time of the contact, the lamp is stopped. If the optical axis of the head lamp overruns its low position, it is redriven up to a stop of an accurate position.

Abstract: PURPOSE:To equalize the glow discharge in a discharge tube for stabilizing the laser beams by a method wherein a cap and a cathode are connected by an insulator in taper shape so as to make the diameters of the cap and the cathode continuous to each other. CONSTITUTION:A cylindrical cap 22 having slits 21 is formed on the end of a blast pipe 9. Next, an insulator 23 in tapered diameter is fixed to the cap 22 so as to provide a ring type cathode 2 halfway on the insulator 23. At this time, the insulator 23 is composed so that the inner diameter of the cap 22 and that of the cathode 2 may be continuously fluctuated. Then, a laser output can be stabilized by specifying the taper length L and the taper angle theta to be within specific range. Through these procedures, the stable glow discharge can be obtained to stabilize the laser output without setting up the eddy current between the blast pipe 9 and the cathode part connecting to a discharge tube 1.
