Patent JP-S62142356-A (JP)
Title: Transistor
Inventor: TERAJIMA TAKAMI
IPC: H01L29/73
Filed: 1985-12-17
Abstract: PURPOSE:To obtain an excellent high-speed switching characteristic, large reverse-bias secondary breakdown withstanding quantity, large design freedom and excellent high- current characteristics, by providing a low resistance region, whose conductivity is the same as that of a base region, at the central lower part of an emitter region, and providing an emitter connecting hole at the central upper part of the emitter region. CONSTITUTION:A second conductivity type (e.g., p<+> type) low resistance region 11 is provided beneath the central part of a first-conductivity type (e.g., n<+> type) emitter region 4. Therefore, the central part of the emitter region 4 becomes a transistor part, where emitter injecting efficiency is low and a current amplification factor is low at the central part of the emitter region. Even if the conducting region is moved from the peripheral part to the central part in the emitter region 4 when the transistor is turned OFF from ON, minority carrier injection at the central part is cut off at the earlier stage. Namely a fall time tf becomes relatively short and an excellent high-speed switching characteristic is obtained. Even if current is concentrated at the central part of the emitter region 4 when the ON state is switched to the OFF state, the degree of concentration (current density and time) is decreased, and a reverse- bias secondary breakdown withstanding quantity becomes large.

Inventor: SAHO NORIHIDE
IPC: F25B9/00
Filed: 1990-10-24
Abstract: PURPOSE:To prevent an amount of liquefaction in a liquefaction machine and an amount of freezing from being reduced by a method wherein an impurity gas adsorption means is disposed in a low pressure circuit in the liquefaction machine. CONSTITUTION:Impurity gas released form a liquid helium tank 14 and an ultra-conductive magnet 15, for example, remaining water in the liquid helium tank, hydrogen gas from within wall, organic gas from adhesive agent used or CO2 gas from within the magnet flow within a low pressure pipe and are heated by the fifth, third and first heat exchangers 12, 9 and 6, gasified and further adsorbed at the adsorption agent, for example, an active carbon in the adsorption devices 17, 18 and 18a disposed at each of the outlets, resulting in that these impurity gases are not condensed or adhered to a high pressure pipe and a heat exchanger and a Jule-Thomson valve. Accordingly, it is possible to prevent a reduction of an amount of liquefaction and a freezing volume of the liquefaction machine without contaminating the heat exchanger and the Jule-Thomson valve.

Title: Finder system
Inventor: MURATA YASUNORI
IPC: G03B13/02
Filed: 1994-10-24
Abstract: PURPOSE: To effectively stop harmful ghost light or flare light and to ensure observation of a good finder image by suitably determining the shape of an aperture of a diaphragm, which is installed in an objective lens. CONSTITUTION: An object image, which is formed on a primary image forming plane by means of an object lens L0, is reversed into a normal, erecting image by means of an image reversing optical member LP. Then, observation of an object image (finder image) of the normal, erecting image is carried out via an ocular lens LE at a pupil position (Q). Now, let the direction of an optical axis be a Z-axis, so that X-, Y-axes are set in a plane perpendicular to the Z-axis. Roof-edge line (D) of a roof-reflecting surface P2C is situated within the X-Z plane. The shape of an opening part of a diaphragm (S) consists of repeated, continuous (or discontinuous) waveform, comb-form, or a saw-tooth form, which lies in the X-Y plane and is symmetrical with respect to the X-axis.  With this contrivance, harmful stray light can be stopped, and, even if the pupil position for the observation is moved in the vertical direction, the roof- edge line is not observed, thereby enabling the observation of a good finder image.

Title: Boat with floating body
Inventor: ISHIGAKI EIICHI
IPC: B63B35/73
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To prevent rolling and allow a stable high-speed cruise by fitting a floating body to the outside face section of the hull of a boat capable of cuising by ejecting the water sucked by a propelling pump provided at a bottom section for the cruise. SOLUTION: When a jet pump 3 is driven by a drive motor 2, the water sucked from a suction port 4 is ejected from a discharge port 5, and a boat can cruise. If a mixed flow pump having a spiral centrifugal vane is used for the jet pump 3, a high-pressure water jet can be ejected, no cavitation occurs, and the boat can stably cruise at a high speed. A floating body 6 provided along the broadside floats a hull, mitigates the resistance of waves, widens the boat width, prevents a rolling action, and allows a stable cruise.

Abstract: PURPOSE:To restart a load from its initial state by stopping feeding electricity to the load once automatically after a saving process at the time of the power failure of the load, and then starting feeding electricity again. CONSTITUTION:A nonvolatile memory (i) on the side of a load device is stored with the load feeding stop delay time (T1) required for the in-power-failure saving process and the delay time (T2) from the stop of load feeding to the restart of feeding. If a power failure occurs and then recovers within the time T1, the operation of an inverter (e) is stopped and an AC switch (c) is turned ON to continue to supply the commercial electric power directly to the load. A switch (d) is turned off the time T1 later to stop the electric feeding to the load, the time T2 is clocked, and the switch (d) is turned on the time T2 later to refeed the commercial electric power to the load. If the power failure recovers after the time T1 is elapsed, the operation of the inverter (e) is carried on until the end of the clocking and then stopped with a stop signal I. The switch (d) is turned on only during the clocking of the time T2, so the switch is turned on when commercial power supply recovery to restart the load.

Title: Thin film transistor array
Inventor: OKA HIROSHI
IPC: H01L29/786
Filed: 1989-10-31
Abstract: PURPOSE:To constitute the thin film transistor array so that a gate bus wiring of a low resistance is provided, and even in an etching process, disconnection, peeling, etc., are not generated by providing a middle layer between the lower gate wiring and the upper gate wiring, and providing a through-hole on the middle layer. CONSTITUTION:On the whole surface on the lower gate wiring 12 and the lower gate electrode 4, a middle layer 18 is accumulated and on the middle layer 18 on the lower gate wiring 12, a through-hole 17 is formed. In this case, the lower gate wiring 12 is not exposed to an etchant used at the time of forming a pattern of the upper gate wiring 3, since it is covered with the middle layer 18. Also, since the lower gate wiring 12 and the upper gate wiring 3 are connected electrically through the through-hole 17, a specific resistance of the whole gate bus wiring 16 becomes small. In such a way, a resistance of the gate bus wiring is reduced, and generation of disconnection, peeling, etc., of the gate bus wiring is also reduced.

IPC: B65H23/198
Filed: 1989-10-31
Abstract: PURPOSE:To reduce the width difference of a taken-up sheet by taking up the sheet in roll form on a taking-up core by a taper tension in which tension is reduced in straight line form from the start of taking-up to the end and specifying the taper rate theta. CONSTITUTION:When a sheet is taken up in roll form, taking up is carried out with a taper tension in which tension reduces in rectilinear form from the start of taking-up to the end, and the tension is set as follows; 400<=(2.88-0.0104theta)deltas<=1000 with a taper rate theta of 5-80%, where deltas is the tension at the start of taking-up, and if the tension at the end is deltae, theta is represented by (deltas-deltae)/deltasX100. Accordingly, the difference in the width direction of the taken-up sheet is suppressed within 2% or less of the specification, and the generation of slip-off of a core is suppressed by carrying out taking-up by controlling the taper tension from the start of taking-up to the end by programs, so that the above-described equation is satisfied.
