Patent JP-S6188615-A (JP)
Title: Switch circuit
Inventor: TOKUNAGA KIICHI
IPC: H03K17/10
Filed: 1984-10-05
Abstract: PURPOSE:To avoid an intermittent phenomenon of a GTO which is produced in case a load current does not reach a holding current, by providing a gate current supply circuit using an MOSFET between the anode and the gate of the GTO. CONSTITUTION:Both an MOSFET51 and a GTO11 are turned on when a positive gate signal is impressed. Then an MOSFET52 and a GTO2 are also turned on. Thus the ON actions 51-5n are kept ON while the positive gate signal that can prevent the reduction of the electric charge between the gate and the source of the FET51 is impressed. Thus the switch circuits are kept ON, although the load current is set less than the holding current of the GTO.

Title: Lead frame and manufacture thereof
Inventor: NISHINO TOMONORI
IPC: H01L23/50
Filed: 1991-07-24
Abstract: PURPOSE:To increase lead gaps and prevent bridge accidents, by shifting the lead thickness direction position of an overhang part tip, higher or lower than the lead thickness center. CONSTITUTION:Sectional shape of a part except the inner lead tip of each lead 2 is so made that the height of a tip 9 of an overhang part 8 generated by side etching is shifted higher or lower than the center position in the thickness direction. Thereby the protruding amount of the tip 9 of the overhang part 8 can be reduced, and the interval between the tips 9, 9 of adjacent leads can be reduced. Hence the generation ratio of an accident that the outer leads are mutually bridged can be reduced. In 3 first etching process, the part to be finally eliminated is subjected to light etching from the surface and the rear. Inner lead tip end-portions are subjected to light etching only from the surface. In a second etching process, the periphery of the inner lead tip is subjected to light etching from the surface and the rear, and the width and the pitch of the tip is made fine.

Filed: 1987-08-21
Abstract: PURPOSE: To prevent leak of pyrogenic fluid by pressing an outer annular member on the opposite metal outer pipes, engaging an inner annular member outward the opposite ceramic inner pipes and forming a space between the inner annular member and the end of the outer pipe. CONSTITUTION: A double-walled structure is formed by a ceramic inner pipe 22 and an outer pipe 23 relatively movably engaged with the inner pipe 22. Flanges 25, 25 are formed at the end portions of the outer pipes 23, 23, and pressed between the end surfaces thereof via an outer annular member 26. An inner annular member 30 is engaged outwardly with the end portions of the inner pipes 22, 22 in a tight way. The external diameter D1 thereof is smaller than the internal diameter D2 of the outer annular member 26, but larger than the internal diameter D3 of the outer pipe 23. A space δ is formed between the axial end of the inner annular member 30 and the opposite ends of the outer pipes 23, 23.  As a result, it is possible to prevent leak of pyrogenic fluid in double ways, to compensate the heat expansion difference between the outer pipe and the inner pipe and prevent damaging the pipe.

Abstract: PURPOSE:To remove a longitudinal stripe and the beats which reduces the picture quality by separating and providing a signal processing part and a synchronizing signal generating device from a solid-state image pickup element, a driving circuit, etc., and using a shift register as a frequency dividing circuit. CONSTITUTION:A solid-state image pickup element 1, a driving circuit 2, a driving pulse generating device 3, a voltage control transmitting device 6, a shift register part 4, etc., are separated as an A block and a signal processing part 8 and a synchronizing signal generating device 10 are separated as a B block.

Title: Controlling method for meandering
Inventor: MIURA HIROAKI
IPC: B21B37/00
Filed: 1986-09-05
Abstract: PURPOSE:To positively avoid generation of rapid swerves caused by improper shapes of the rear end part and failures by determining a finishing position of meandering control in accordance with shapes of the rear end part of a rolled stock and then holding a correction amount constant. CONSTITUTION:In the case that the center line CL of the rear end part of a rolled stock is improper shape, rapid swerves are generated by actions trying to align the CL with the mill center. A rear end part shape detector 20 such as a CCD camera is installed in the upstream of a rolling mill 1A performing meandering control, detects rear end part shapes, and predicts a length (y) of the improper rear end part on the inlet side of the mill 1A. A point at which the stock moves forward by a distance S=L1-(L2+y) is determined as a meandering control finishing point and then a draft correction amount is held constant until runout. As the result, troubles such as rapid swerves of the rear end and squeezing failures are positively avoided.

A fan 22 is driven by a motor 23 to suck air from the slit 21 and air at the circumference of the exposure part 10a as well, and discharges the air out of the machine through the opening part 25 of the main frame 24. A switch 26 four turning on and off the fan 22 is operated regardless of the operation of the power switch 28 of the electric and electronic circuit part 27 of the copying machine main frame 4. In this case, the air may be blown out instead of sucking the air.

Title: Automatic braking device for vehicle
Inventor: DOI AYUMI
IPC: B60T8/172
Filed: 1991-08-21
Abstract: PURPOSE:To execute automatic braking early enough to surely avoid contact in the case where a preceding vehicle is in an undesirable travelling state such as sudden deceleration and meandering, by detecting this state to change a threshold value for the possibility of contact into a larger one. CONSTITUTION:The automatic braking device computes a distance between an obstacle such as a preceding vehicle or the like and own car and relative speed based on the output of an ultrasonic radar unit 31 provided on the front part of a car body through a computing unit 32, and when it is judged from the computed result that own car has possibility to come into contact with the obstacle, an actuator 16 executes automatic braking to brake each wheel. In this case, the computing unit 32 judges whether the preceding car is in the undesirable state of sudden deceleration or not from the outputs of a car speed sensor 42 and of a distance-relative speed detecting means 36, and when the preceding vehicle is judged to be in the undesirable state, a threshold value for the start of the automatic braking is changed to be larger than that in the other cases. Thus the automatic braking is executed early enough to surely avoid the contact.

Title: High-speed solenoid valve, particularly, fuel injection pilot valve for diesel engine
Inventor: MARIO RIKO
IPC: H01F7/16
Filed: 1988-08-25
Abstract: PURPOSE: To obtain good action of an injection valve by arranging plural openings in notch shape in periphery of an armature itself of a solenoid metering valve. CONSTITUTION: An armature 13 has plural radical openings in notch shape 14, and the notches 14 are equally spaced arranged in the periphery to expand the openings of the armature itself 13 in the peripheral direction. Therefore, magnetic induction of the armature 13 is reduced, and eddy current is less generated, so the obturator 11 can rapidly move from open position to close position of the discharge hole A. Furthermore, weight of the armature 13 is reduced by the notch 14, so its inertia is reduced therewith. While the notches 14 are in empty status, the mechanical resistance of the fuel liquid against movement of the armature 13 itself is also reduced. However, while the notch 14 is stuffed, an effective attenuation that reduces the influence of the obturator 11 going to the close position is resultant.
