IPC: B30B1/32
Filed: 1984-02-29
Abstract: PURPOSE:To increase the speed of a liquid pressure double-action press by providing two-eccentric gears which have eccentric bodies and rotate synchronously and operating synchronously an inner ram and outer ram. CONSTITUTION:Eccentric gears 13A and 13B having eccentric bodies are synchronously rotated via a flywheel 18 and clutch by a driving mechanism 12. The eccentric bodies of the gears 13A and 13B have different phases and eccentricity and are so set that while one eccentric body is at the top dead point the other is advanced slightly in phase. The inner plunger 15A and outer plunger 15B synchronized with the gears 13A, 13B actuate an inner ram 2a and outer ram 2B to make stroke motion via respective operating pipings 6A, 6B. The speed of the liquid pressure type double action press is increased and considerable energy economization is attained by the above-mentioned mechanism.

IPC: H03K17/732
Filed: 1988-02-19
Abstract: PURPOSE:To measure the turn-off gain without varying other turn-off condition by providing a constant current power supply and a gate current supply source connected in parallel with a high voltage power supply to quicken the leading of a current and supplying a gate turn-off current to a GTO thyristor from the circuit comprising the series connection of them. CONSTITUTION:With a turn-on signal supplied to a transistor(TR) 4 from a gate signal source 5, the TR 4 is turned on, and a gate turn-off current is supplied to the gate of a GTO thyristor 1 through the TR 4, a resistor 9 and a reactor 13 from a capacitor 12 charged up to the voltage of a high voltage power supply 6. In this case, a diode 11 is turned off by receiving a reverse bias from the capacitor 12. Thus, the current supplied to the GTO thyristor 1 is suppressed to a constant current IG=IGQ by the effect of the reactor 13. Then the gate turn-off current IGQ is controlled without varying various parameters of the GTO thyristor at turn-off state and the turn-off gain of the GTO thyristor is easily measured.

Filed: 1989-02-20
Abstract: PURPOSE:To prevent the generation of a crack in the corner of a through hole by a method wherein a chamfering part is formed on the peripheral edge of the opening of the through hole, through which circuit layers are connected to each other. CONSTITUTION:Before a through hole 3 is bored in a printed-wiring board formed by adhering a copper foil 10 on both surfaces of an insulating layer 2, a spot facing work is performed on the surface and rear of a place, where the hole 3 is bored, using a drill, such as a drill of a diameter larger than the hole diameter of the hole 3. After that, the hole 3 is bored with a drill of a prescribed diameter and a chamfering part 8 with a prescribed gradient is provided on the peripheral edge of the opening (the edge of the corner part) of the hole 3. Accordingly, even if a thermal stress and a mechanical stress are applied to the board, the stresses are never concentrated on the edge of the corner part of the hole 3. Thereby, a crack is hardly generated in the corner of the hole 3.

Title: Method and device for radiating charged particle
Inventor: ASAI KATSUO
IPC: G21K5/04
Filed: 1989-02-17
Abstract: PURPOSE:To eliminate the need of executing a complicated control, and also, to surely prevent an insulating film from being electrified by irradiating an object having an insulator or an insulating film with a charged particle under the radiation of an electromagnetic wave. CONSTITUTION:A semiconductor wafer 12 is constituted so as to be irradiated with an ion beam 13 consisting of a positive charged particle, and the ion beam 13 is emitted from a radiating means being outside of the figure. In this case, the semiconductor wafer 12 is irradiated with the ion beam 13 in a state that ultraviolet rays are radiated from a lamp 14. As a result, a positive charge caused by radiating the ion beam 13 receives ultraviolet energy and escapes to a rotary disk 11, and it does not occur that its charge is accumulated on an insulating film of the semiconductor wafer 12. Also, since the ultraviolet rays themselves do not electrify the wafer 12 at all, the electrification of the insulating film is always prevented without executing a special control by only supplying sufficient ultraviolet energy.

Filed: 1981-03-18
Abstract: PURPOSE:To cut an end plate (ear chip) in the best condition and reduce generation of scrap to a minimum, by controlling the feed amount of a sheared work at shearing of the ear chip in a side shear. CONSTITUTION:If shearing work is started, a sheared work is transferred by the preset amount at a fixed pitch through a tape roller 14 and pinch rollers 12a, 12b for every one cut operation of a side shear. A tail end moving distance l, after detection of a tail by a tail end detector 15 to a position where the sheared work 13 is stopped for shearing operation, is calculated from a number of revolutions of the pinch roller 12b (or 12a). Residual length of the sheared work 13,  if assumed L for a distance from the end plate cut position by a shear knife to  the tail end detector 15, can be obtained from (L-l). Hence, considering actual  shearing length, condition of an incidental equipment, end plate binding, etc., a feed amount of the sheared work 13 is controlled by a control device 10 so that  said residual length can be equally divided, thus optimum dimensions of the end  plate can be obtained.
