Title: Fuel cell power generating system, and its nitrogen purge method and temperature raising method
Inventor: IWASA NOBUHIRO
IPC: H01M8/04
Filed: 1990-03-07
Abstract: PURPOSE:To carry out nitrogen purging in a short time by feeding the nitrogen from a nitrogen feeding pipe from the downstream side of a desulfurizer through a cutoff valve. CONSTITUTION:A nitrogen feeding pipe 23 linking to a nitrogen device 11 provided at the downstream side of a desulfurizer 3 through a cutoff valve 24 is provided, and when the system is stopped, the cutoff valves 10 and 25 on material fuel feeding pipes 8 and 9 are closed, and at the same time, a cutoff valve 27 on an atmosphere discharge pipe 26 is opened while cutoff valves 13 and 24 on nitrogen feeding pipes 12 and 23 are opened, so as to start the nitrogen purging in an inflammable gas system. That is, the desulfurizer 3 and the inflammable gas system at the rear stream side including a reformer 2 and a fuel cell main body 1 are separated from each other, and the nitrogen purging is carried out. As a result, the hydrocarbon fuel in the desulfurizer 3 is never fed to the reformer 2 after the nitrogen purging is started. Consequently, the nitrogen purging in the inflammable gas system at the rear stream side including the reformer 2 and the fuel cell main body 1 can be finished in a short time.

Title: Image processor
Inventor: SAWADA YORIO
IPC: G06T7/00
Filed: 1983-04-01
Abstract: PURPOSE:To determine height information efficiently for a stereo-pair image with a simple calculation by calculating a Fourier coefficient at one desired point of two images different in the view point to determine the height based on the deviation from the coefficient value. CONSTITUTION:A Fourier coefficient is calculated for the total sum of image data in a small area centered on the point (i,j) corresponding to two images A and B with a parallax in the direction (x) of two orthogonal directions (x) and (y). The deviation of the image is calculated corresponding to the parallax in the direction (x) from a corresponding relationship of the Fourier coefficient with one desired point (i,j) of the two images to determine the altitude difference due to the parallax varying depending on the distance of an object from the view point. Thus, height information can be determined efficiently for a stereo- pair image for a short time with a simple calculation.

Title: Garbage packing apparatus including container connected to garbage press
Inventor: ERUBIIN KARUDENBAHA
IPC: B30B9/30
Filed: 1984-03-27
Abstract: A refuse packaging assembly of the kind comprising a refuse press having a pressing plunger which is axially movable in a pressing box, and a container which is adapted to be connected to the outlet end of the pressing box in order to be filled with refuse by the plunger, the container having a closure plug which is uncoupled from the container and coupled to the plunger for movement therewith when the container is connected to the press. The container carries at least one spring loaded pin which is biased into a coupling aperture in the closure plug to couple the two together, and the plunger carries at least one weaker spring loaded pin which aligns with the coupling aperture when the container is moved into position for connection to the press and the plunger is moved to a coupling position. A coupling lever which is operated by a power actuator to securely hold the container connected to the press simultaneously acts to retract the container pin from the coupling aperture, thereby uncoupling the plug from the container and allowing the plunger pin to move into the aperture to couple the plug to the plunger. Releasing the coupling lever automatically leads to uncoupling of the closure plug from the plunger and recoupling to the container.

IPC: B05D5/00
Filed: 1995-03-16
Abstract: PURPOSE: To produce an organic pigment-colored coated steel sheet which has workability and high weather resistance and to provide its producing method. CONSTITUTION: This inorganic-organic fused material-coated steel sheet is the one which is covered with a film formed by mixing or dissolving an organic pigment in an inorganic-organic fused material obtained by replacing M in an inorganic polymer skeleton having M-O-M bond (M is a metal or metalloid element) with O-Si(R)2 -O group (R is an alkyl group). The steel sheet is produced by adding a dialkyl dialkoxy silane into an alkoxide or a hydrolized alkoxide followed by hydrolyzing, adding the organic pigment to the hydrolyzed solution, applying it on the steel sheet, drying and baking. Thereby colored coated steel sheet having a conventionally impossible color when using an in organic pigment can be produced only by using this inorganic-organic fused material coated steel sheet, since the change in color with the lapse of time is reduced even if using an organic pigment.

Abstract: PURPOSE:To use one coil for a correction coil and a degaussing coil in common by applying a voltage whose amplitude is being attenuated to one terminal of the magnetic field correction coil and applying a voltage in response to the detection of a magnetism azimuth sensor at the other end. CONSTITUTION:A voltage whose amplitude is being decreased is applied to one terminal of a magnetic field correction coil 13 and a voltage in response to a magnetic field detected by a magnetism azimuth sensor 24 is applied to the other terminal of the magnetic field correction coil 13. Since the AC degaussing current whose amplitude is decreased flows to the magnetic field correction coil 13 while being superimposed onto the DC earth magnetism correction current in response to the horizontal component of the earth magnetism to cancel the earth magnetism acting on a CRT thereby eliminating magnetization. Thus, the magnetic field correction device using the correction coil and the degaussing coil in common is used.

IPC: H03F3/347
Filed: 1984-03-28
Abstract: PURPOSE:To improve the offset control function by adding a circuit which compensate the offset to an offset compensating circuit consisting of an integration circuit and a switch. CONSTITUTION:An offset compensation circuit consists of an integration circuit containing an operational amplifier A14, a resistance R17 and a capacitor C11, a switch S13 and a resistance R18. This offset compensating circuit compensates the offset of an operational amplifier A13 but it is impossible to set said offset at a level lower than the offset voltage of the amplifier A14. Therefore an integration circuit consisting of an operational amplifier A20, a resistance R21 and a capacitor C20 is added together with an offset compensating circuit consisting of a switch S22 and a resistance R20 and a zero-voltage input circuit consisting of switches S20 and S21. This offset compensating circuit controls the offset voltage of the amplifier A14. Thus the offset control function is improved further.

Title: Pellicle
IPC: G03F1/62
Filed: 1992-03-17
Abstract: PURPOSE:To prevent the adhesion of foreign matter onto a mask pattern in spite of the intrusion of the foreign matter between a transparent film and a mask by forming a tacky adhesive material on one surface of the film existing on the inner side of a frame and to obtain a pellicle which does not transfer on the wafer. CONSTITUTION:The pellicle consisting of the transparent film 1 and the annular frame 2 is constructed by applying the material 3 which is transparent and is tackiness on the front surface of the transparent film 1 existing on the inner side of the frame 2. Since the tacky adhesive material 3 exists on the film 1, the foreign matter is eventually fixed onto the film 1 even if the foreign matter intrudes on the film 1. The foreign matter is thus prevented from entering the photomask. The surface of the transparent film existing on the inner side of the frame is formed tacky adhesive in such a manner, by which the foreign matter is prevented from sticking to the pattern surface of the photomask even if the foreign matter intrudes therein. Then, the transfer of the foreign matter onto the wafer is prevented and the degradation in the quality of a semiconductor device is obviated.
