Title: Press working method
Inventor: SHIMIZU MITSUHARU
IPC: H01L23/50
Filed: 1988-12-16
Abstract: PURPOSE:To reduce generating flashes and to prevent generating cracks by forming a groove on the rear side of the blank material spanning a punching line on the whole punching line or on a part, then, by punching from the front side of the blank material along the prescribed punching line. CONSTITUTION:In case of manufacturing a lead frame 10, at first, on the rear side of a metallic band, the V-groove 28 is notched so as to include the whole inner lead part 12 or the side edge to be the side edge of the inner lead 12 near the boundary part between the outer lead part formed at the time of forming the lead frame, and along the side edge. Then, the metallic band is punched from the front into the lead frame pattern by using a press die to perform chambering by remaining a part of inclined wall of the V-groove 28 on the side edge. Therefore, because the punching thickness by the press is reduced, the flashes by the press work is reduced as far as possible, the generation of cracks on a enclosing resin and low melting point glass are prevented.

Abstract: PURPOSE:To keep off any seizure or binding of a bearing by supporting an upper end of a shaft connecting a machine part to a motor installed on top of it with this bearing being situated on top of the motor, and installing an oil duct interconnecting a vane back space at the vane outer diametral side to this bearing. CONSTITUTION:A machine part 18 and a motor 2 installed on top of it are connected to each other through a shaft 8. Bearing 3, 4 supporting a cylinder 5 and a piston 6 in this machine part 18 up and down are lubricated by lubricating oil 20 via an oiling port 11. In comparison with this, an upper end of the shaft 8 is supported by a shaft upper and bearing 9 at an upper position of the motor 2. Accordingly, this bearing 9 is interconnected to a vane back space 21 at the vane outer diametral side by an oil duct 22. Therefore, the lubricating oil 20 collected in the lower part of a closed casing 1 is fed to the shaft upper bearing 9 by way of the oil duct 22 by vane pumping action being produced by reciprocating motion of a vane 7 at the vane back space 21, thereby lubricating the bearing 9, thus seizure or binding is preventable.

Title: Bath tub hot water supply device
Inventor: KATO SHOZO
IPC: F24H1/00
Filed: 1987-12-16
Abstract: PURPOSE:To know easily the time to end hot water fill-up work, by installing an arithmetic operation means to calculate a differential water level between a bath tub water level and a preset water level, an arithmetic operation means to calculate water level change speed, an arithmetic operation means to calculate hot water fill-up remaining time, and an indicator to display hot water fill-up remaining time. CONSTITUTION:A differential water level is calculated based on a water level detection signal and a water level setting signal in a differential water level arithmetic operation circuit 26. When the differential signal is output from the differential water level arithmetic operation circuit 26 to a water level change speed arithmetic operation circuit 27, a water level change speed is calculated based on the differential water level signal in the water level change speed arithmetic operation circuit 27. Then, a hot water fill-up remaining time arithmetic operation circuit 28 receives a water level signal and a water level change speed signal, divides the differential water level with the water level change speed based on their respective signals, and calculates hot water fill-up remaining time. As a result, a time signal is output to an indicator 23 from the hot water fill-up remaining time arithmetic operation circuit 28, and the indicator 23 displays hot water fill-up remaining time. Therefore, a user can easily know the length of time required to end hot water fill-up work.

Title: Internal combustion engine
Inventor: MASHIYUU JIEI SHIYUNEIDAA
IPC: F02D35/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a gas blowby sensor by which the flow of the blowby gas of a crank case can be periodically or, desirably, continuously observed. SOLUTION: In the ventilation device of a closed crank case, the gas of the crank case can flows through a venturi 10 having high pressure and low pressure taps. The high pressure and the low pressure taps 24, 28 are connected to a differential pressure transducer which produces an output proportional to the flow rate of the gas passing the venturi 10. By using the venturi 10 in connection with the differential pressure sensor, a low pressure path for the crank case gas is provided, and blowby can be continuously observed without exceeding the working pressure limiting of various oil seals. Such sensor is particularly suitable for the ventilation device of the closed crank case (CCV). Because, no gas is required to be discharged, and the sensor works well even in an opened crank case ventilation device.

Rotary shafts 9 are thus rotated integrally, and support parts 10 fixed at their upper ends are rotated in opposite directions to each other, that is in an opening direction. A screw tightening tools 11 at the forward end of the support shafts are also rotated in the opening direction corresponding to their rotation, till a pitch between their driver bits reaches a predetermined distance. Each drive but thus coincides with desired screw tightening positions respectively, thereby positioning of two screw tightening tools 11 is completed.

IPC: H03G3/20
Filed: 1989-12-08
Abstract: PURPOSE: To improve the linearity of an amplifier at the time of changing a power, to improve precision, and to reduce distortion by generating an error signal indicating a difference between the output of an amplifier and a level control voltage, and dynamically controlling an operating bias point. CONSTITUTION: A variable reference voltage VREF( V) is supplied to three RF amplifiers 22, 24, and 26 by an output from a dynamic bias control amplifier 42, and the operating bias points of those three amplifiers are continuously changed according to a desired synthetic output level. A control voltage to an automatic level control(ALC) loop is a signal changing in proportion to a desired RF power, and this signal is also used for controlling the rate of a collector voltage Vc to collector currents Ic to be impressed to one or more RF amplifiers. When an intermediate output with a few higher harmonics is necessary, the value of the collector voltage Vc is made large, and the value of the collector currents Ic is made small. When the large RF power is necessary without normalizing the higher harmonics, the collector currents Ic with a large value are used.  The collector voltage Vc is decreased according to the increase of the collector currents Ic so that loss can be reduced.
