Title: Bidirectional manipulator
Inventor: KUWATANI TOSHINORI
IPC: G05G11/00
Filed: 1994-03-25
Abstract: PURPOSE:To normally operate an operating member, which is turned from a neutral position into two directions, with an electric motor to be turned forward and backward by a switch operation, but to manually operate the operating member when any fault is generated in an electric system. CONSTITUTION:By fitting a nut member 25 through a helical line 24 to a control rod 22 so as to freely slide the nut member and turning the control rod 22 forward and backward with the electric motor, the nut member 25 is shifted from the neutral position to one axial direction and the other axial direction, the forward and backward turn of the control rod 22 is transmitted through first and second clutches 30 and 31 to be closed by this shift in two directions to the operating member to be turned through an output rod, and a manipulating member to be manually manipulated is linked to the output rod.

Title: Heat exchanger for high temperature
Inventor: MAEHARA SEIJI
IPC: F28D7/16
Filed: 1985-03-20
Abstract: PURPOSE:To prevent a primary side liquid from flowing out to an external side and leave out a provision of a guard vessel by a method wherein an arrangement is made so that the primary side of liquid with a high temperature may always keep flowing within an internal shell, even in a case of flowing out the liquid, it may be physically surrounded by either a secondary side liquid or the internal shell. CONSTITUTION:A space between an external shell 11 and an internal shell 13 is filled exclusively with the secondary side sodium 19, further, a passage for the primary side sodium 35 is placed wholly inside of the internal shell 13. Also an arrangement is made so that an operating pressure of the secondary side of sodium 19 may keep greater than that of the primary side of sodium 35, accordingly, even in a rupture case of a piping equipment, the secondary side sodium 19 is flowed into the inside of the internal shell 13, not to the primary side sodium 35. Granting that the operating pressure of the secondary side sodium 19 is smaller than that of the primary side sodium 35, the running off sodium from the primary side, due to the piping rupture, is physically covered with the internal shell 13 from flowing out to the external side. Namely, since the internal shell 13 has its role as a guard vessel, it is possible to leave out a conventional type of guard vessel.

Abstract: PURPOSE:To produce a cathode-ray tube having excellent uniformity of luminance and chromaticity while preventing the secondary agglomeration of fine particles by adding a fluorescent material to a liquid composed mainly of water under stirring at a high speed, adding a binder composition to the mixture under stirring at a low speed and applying the obtained slurry of a fluorescent material. CONSTITUTION:A fluorescent material is added to a liquid composed mainly of water spending a prescribed period while stirring the liquid at a high speed with a homodisper (usually having a stirring blade of 5-10cm diameter and operated at a rotational speed of 3,000-15,000 rpm) at a circumferential speed of 6-25m/sec. The obtained mixture is stirred at a low speed (a circumferential speed of 0.1-1.0m/sec) together with a binder composition composed of a PVA solution containing e.g. ammonium bichromate, ammonia and a surfactant. The obtained fluorescent material slurry is applied to the inner surface of a cathode-ray tube panel to form a fluorescent face.

Title: Focus error detector
Inventor: HAMANAKA KENJIRO
IPC: G11B7/09
Filed: 1985-03-20
Abstract: PURPOSE:To detect the focus error in a high speed with a low cost by detecting the moving direction of interference fringes which is changed in accordance with the focusing state of light to a recording medium and counting the number of interference fringes in accordance with the moving direction by a counter to detect a focus error signal. CONSTITUTION:The light incident from a beam splitter 3 is slightly shifted to beams 33 and 34 by a phase diffraction grating 31, and interference fringes are formed in accordance with this shift and are projected onto a photoelectric detecting means 32. Two photoelectric detecting means A1 and A2 are provided at least as the photoelectric detecting means 32, and outputs are inputted to an up/down counter 35. When the focusing state of light to a recording medium 5 is changed, interference fringes are moved left or right on photoelectric detecting means A1 and A2, and the number of interference fringes is counted up or down by the counter 35. If the counter 35 is reset in the in-focus position, the output is zero in the in-focus position, and the sign and the absolute value of the counted value indicate the direction and the extent respectively when light is deviated from the in-focus position. Thus, the focus error is detected in a high speed with a low cost.

Abstract: PURPOSE:To prevent any aluminum hillock from being produced and hence make uniform sensitivity among pixels by sputter-evaporating an optical shielding and wiring Al-Si alloy film at silicon substrate temperature controlled to a specific temperature or lower. CONSTITUTION:A solid-state image sensing device includes an N type impurity layer 4 constituting an optical detector part of a photodiode, an impurity layer 5 comprising a buried channel type CCD N type well constituting a transfer line part for reaching a signal charge, and an optical shielding film 10 comprising an Al-Si alloy film having an opening part on the optical detector part of the photodiode and optically shielding the transfer line part. The optical shielding and wiring Al-Si alloy film is sputter-evaporated in the state where silicon substrate temperature is controlled to be 35 deg.C or lower. With the film formation process, any aluminum hillock is prevented from being produced owing to heat treatment and hence variations of the opening area of the photodiode part is reduced. Thus, a solid-state image sensing device with reduced sensitivity variations among pixels can be manufactured.

Title: Hetero-junction bipolar transistor
Inventor: NOZU TETSUO
IPC: H01L21/331
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain a hetero-junction bipolar transistor with a high fmax and a high current-amplification factor by forming a collector layer that is formed on a semiconductor substrate by lamination and is connected to a base layer, in such a manner that the cross section of the collector layer will be almost in T shape. SOLUTION: A first collector layer 4 whose area of is almost equal to that of an external base region is formed beneath the external base region, and a second collector layer 6 whose area is smaller than that of the first collector layer 4 is formed beneath the first collector layer 4. In ordinary operation of the transistor, the base-collector junction is reverse-biased; therefore, electrons in the external base region are accelerated by the collector layer 4 and reach the collector electrode without being recombined with one another. As a result, the current-amplification factor is not reduced even if the element is microminiaturized. Since the area of the second collector layer 6 is smaller than that of the external base region, it is possible to reduce the parasitic capacitance of the collector, which leads to a high fmax .  This makes it possible to obtain a high fmax and a sufficient current-amplification factor.

Filed: 1995-03-16
Abstract: PURPOSE: To perform the continuity inspection and waterproof inspection of a waterproof connector once, and improve the inspecting precision by notifying that both the continuity and waterproof inspections are passed when the connector satisfies the continuity and the absence of erroneous leak. CONSTITUTION: When a continuity inspection and a waterproof inspection are carried out, the air valve of a compressor 5 is opened to start the air supply to an inspecting machine 2. A waterproof connector C is held in the sealed state by the housing part 22 and inspecting part 23 of the inspecting machine 2, and the air is supplied to the inner part of the connector C. Whether an air leak is present in the connector C and whether the continuity between each terminal metal fitting of the connector C and each detecting element 233 of the inspecting part 23 is obtained are simultaneously inspected. When no air leak is present, and a pressure rise is detected by a pressure sensor 6, it is judged that the waterproof inspection is passed to light the OK lamp 11 of a judgment box 11, and a passing signal is outputted to a continuity machine 4.  When the continuity machine 4 detects the continued state, the OK lamp 41 of the continuity machine 4 is lighted, and passing signals of the both are outputted to an OK stamper 7.
