Inventor: UEDA HIROSHI
IPC: H05K3/36
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To avoid disconnection or the like caused by shrinkage of a circuit board after thermo-compression bonding, by restraining the circuit board from being connected to a connecting terminal portion of a film carrier as it is keeping a state where the circuit board expands with applied heat and extends longitudinally of the circuit board, when the connecting terminal portion of the film carrier and the circuit board which are to be interconnected are sandwiched between a stage and a tool and are thermally compression-bonded.

Title: Electronic switching circuit
Inventor: UEHARA HIROYASU
IPC: H03K17/16
Filed: 1983-06-24
Abstract: PURPOSE:To increase dv/dt endurance of a thyristor by connecting a resistance between a constant current source and a P gate of the thyristor and further connecting a diode between the constant current source and the base of an NPN transistor. CONSTITUTION:When a constant current source 7 is made inactive state, and an abrupt potential change is given to a cathode 3 in the direction lower than impressed voltage state up to that time, transient current flows from a power source terminal 4 through a capacity component of the constant current source 7 and through a resistance 9 to drive the P gate of a thyristor 1. However, if the transient current is large, potential drop of the resistance 9 becomes large and the current is shunted to a diode 10 side to drive the base of an NPN transistor 6. At the same time, transient current from a PNP transistor 5 is inputted to the base of the transistor 6. Transient current from the constant current source 7 and transient current that passes each junction from the P gate of the thyristor 1 is absorbed by the collector of the transistor 6 and clmaps voltage between the gate and cathode of the thyristor 1. Accordingly, malfunction of the thyristor 1 due to dv/dt can be prevented.

Title: Carriage transfer controller in optical disk device
Inventor: SUZUKI HARUYUKI
IPC: G11B7/09
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress the objective lens displacement low under stable control without using an expensive carriage drive system. SOLUTION: This carriage transfer controller basically transfers a whole carriage by a carriage transfer servo means 13 with a control voltage according to a minute displacement amount by a tracking servo, and at this time, when a rectangular wave voltage is added by an adder 17, a carriage starts to move with a voltage extremely lower than the start voltage, and moreover, it moves smoothly. It is through the reason is that a carriage drive motor is oscillated with a minute amount by adding the rectangular voltage, and an effect of static friction is eased to become nearly a dynamic friction state. Thus, the carriage is transferred with the drive voltage corresponding to a small lens displacement, and lens displacement during lens tracking becomes small.

Title: Structure for controlling liquid level in container with open bottom
Inventor: MIYATA OSAMU
IPC: E03D1/30
Filed: 1983-06-22
Abstract: PURPOSE:To suddenly bring up or down the liquid level inside a bottom-opened container when the liquid level outside the container reaches a prescribed position, by fitting a U-tube, through which the inside of the container communicates with the outside, to the container and providing a means which supplies a liquid-sealing liquid into the U-tube. CONSTITUTION:A pilot valve 419 is installed to one end of a U-tube 412 and the lever 418 of the valve 419 makes swinging motions when a float 411 makes upward and downward motions. The swinging motion of the lever 418 operates the valve 419 and opens and closes a passage 415, resulting in the pressure of a pressure control chamber 413 being increased or decreased. When the pressure of the control chamber 413 is low, a flexible tube 410 swells out and the liquid at an entrance 407 flows out through a discharge tube 416. Therefore, when the liquid level outside a container cylinder 402 becomes higher, the liquid inside the U- tube 412 is blown out and the air inside the container cylinder 402 flows out at a stretch and the liquid level suddenly goes up. When the liquid level outside the container cylinder 402 becomes lower, the liquid level inside the cylinder 402 suddenly goes down by means of a similar action.

Title: Gas-insulated electrical apparatus
Inventor: TANIMURA KENICHI
IPC: H01F27/20
Filed: 1985-05-27
Abstract: PURPOSE:To utilize effectively almost all gas for the purpose of cooling the electrical apparatus, to increase the cooling effect of the electrical apparatus, and to improve the conducting ability, by arraying a shielding plate between the inner face of the vessel and the heat generating apparatus, with a gap serving as a gap path spaced between the plate and the inner face of the vessel. CONSTITUTION:When current is conducted through the circuit breaker CB, heat is generated in the main circuit conductor in the insulating vessel 10 and is radiated through the wall of the insulating vessel 10. Owing to this heat, gas between the circuit breaker CB and the shielding plate 20 is heated. The gas heated by the circuit breaker CB rises between the circuit breaker CB and the shielding plate 20 to reach the top of the vessel 1, and then is diffused outwardly through the upper region C1 from the upper end 20a of the shielding plate 20. When the outwardly diffused gas is contacted to the cap plate 1c and the side wall 1a of the vessel 1, heat is exchanged between the gas and the outer atmosphere through the wall of the vessel 1, so that the temperature of the gas can be reduced and the gas descends in the gap D1 defined between the shielding plate 20 and the wall of the vessel 1. During the gas is descending in the gap, heat is exchanged between the gas and the outer atmosphere through the wall of the vessel so that the temperature of the gas can be reduced more and more.

Title: Amplifier

Filed: 1979-09-05
Abstract: PURPOSE:To obtain an amplifier of a simpler push-pull structure having a high efficiency and no switching distortion, by providing the emitter-earthed push-pull output circuit, the bias setting circuit and the bias current control circuit. CONSTITUTION:The output voltage of the DC current sources 18 and 20 plus the resistance volues of the variable resistances 2 and 3 are set properly. And thus the normal B-class or the AB-class operation is secured for the output transistors 10 and 15 in the period during which each of the transistors swings in the forward direction, and the cut-off is prevented during the swing is secured in the cut-off direction. Thus an operation is secured with a smooth curve decided by the characteristics of the exponent function of the diodes 6 and 13 for the transistors. As a result, the similar efficiency to the conventional amplifier can be obtained along with the switching distortion reduced extremely. In addition, the output can be swung up to the power supply voltage since each of the transistors 10 and 15 is used in the emitter-earthed state. And at the same time, the power supply voltage of the driving stage has not to be set higher than the power supply voltage of the output circuit 28, thus increasing the using effieicency of the power source.
