Title: No-contact ignition unit for internal combustion engine
Inventor: TERADA KANECHIYO
IPC: F02P5/14
Filed: 1981-06-12
Abstract: PURPOSE:To stabilize the engine revolution during no-load operation by short- circuiting an generating coil output in an ignition unit, by charging a condenser with the voltage induced by the short-circuit current interruption, and by giving intermittent ignition when the charged voltage becomes higher than the initially charged voltage. CONSTITUTION:When the positive voltage is generated in a generating coil 1, the base current flows in a transistor 3 through a circuit forming a sequence of coil 1  resistance 2  transistor 3  coil 1, and the output from the coil 1 is short- circuited. As the short-circuit current increases, a thyristor 6 is conducted, interrupting the short circuit current suddenly. At this time, a voltage is induced in the coil 1, and electric charges occurs through a circuit forming the sequence of coil 1  condenser 7  diode 8  coil 1. At the time of intermittent ignition, a switch 9 is opened, and a thyristor 13 is not conducted for ignition. When a rotor rotates to induce the positive voltage again in the coil 1, the voltage charges the condenser 7, giving it higher voltage than the first time voltage. And the gate voltage of the thyristor 13 is elevated for conduction, discharging suddenly the electric charge of the condenser 7. This results in intermittent ignition at a plug 15.

Title: Container for semiconductor device
Inventor: SUZUKI KATSUHIKO
IPC: H01L23/44
Filed: 1987-04-13
Abstract: PURPOSE:To make it possible to cool a semiconductor element in a highly efficient manner by a method wherein the area of heat radiation is increased by releasing the heat generated on the surface of the semiconductor element to the side of a metal cap from the surface of the semiconductor using the vaporization heat of an insulating solvent as a heat-conduction medium. CONSTITUTION:A seal frame 13 is adhered to the outer circumference of the upper surface of a ceramic frame body 4, and in the state wherein an insulating solvent 18 is sealed on a cavity II to the extent that the surface of a semiconductor element 6 is covered by the solvent, a metal cap 14 is placed on the seal frame 13, and the ceramic frame body 4 is sealed by fixing it using a resistancewelding method. The heat generated on the semiconductor element 6 is conducted on the ceramic frame body 4 from the rear of the semiconductor element 6, and it is released into the air. At the same time, the insulating solvent 18 airtightly sealed in the cavity 11 is conducted quickly in large quantities on the surface of the metal cap 14 and the side face of the cavity 11 by vaporization and convection, and it is released into the air. As a result, the area of contact with the outside air is increased, and the dissipation efficiency of heat can be improved.

Title: Stabilized power supply circuit
Inventor: NAKAJIMA KAZUHIRO
IPC: G05F3/22
Filed: 1981-06-12
Abstract: PURPOSE:To improve current stability and expand the range of operation voltage by compensating the variation of voltage between the emitter and base of a transistor (TR) which is caused by the change of temperature. CONSTITUTION:When power supply voltage is slightly changed in the direction of increment, the base current flowing into a load resistance 10 is increased. The current variation leads to the increment of the base and emitter current of a TR11. Accompanied with the increment of the emitter current of the TR11, the collector current of a TR14 is also increased. The increment of the collector current leads to the increment of the current flowing into a diode 13 and the reduction of the emitter current of the TR11. Since the diode 13 is inserted between the load resistance 10 and the collector of the TR14, the voltage operation of a TR16 is expanded and the variation of the voltage between the emitter and base of the TR14 due to temperature is compensated.

The distance L' from the calculation circuit 9, the surface temperature thetaS of an object to be measured from surface temperature meter 13, the temperature of a water from a water temperature meter 14 are supplied to a steam film thickness corrector 15. The corrector 15 calculates the thickness of the water vapor film based on these input data and data prememorized. In this manner, the distance L is determined and outputted allowed for the thickness of the water vapor film.

Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of peeling of a metal film at the corner of a sensor chip in dicing. SOLUTION: The method for manufacturing a semiconductor pressure sensor comprises the steps of forming a metal film 4 on one end face of a silicon pedestal 1 formed with a through hole 1a, connecting the other end face of the pedestal 1 to a semiconductor sensor wafer 3 formed with a diaphragm 31 for receiving the introducting pressure from the hole 1a, dicing the wafer 3 and pedestal 1 to separate a sensor chip, and then soldering the film 4 to a stem.

Accordingly, since the film 4 is not formed at the part to be diced, the film 4 is prevented from being peeled at the corner of the chip in dicing.
