Abstract: PURPOSE:To obtain a stable (Y, Ln)-(Ba, Sr)-Cu-O based superconducting material, having the high critical temperature and critical current density, by (calcining) firing a raw material at a specific temperature and adding a drying step after the (temporary) calcining. CONSTITUTION:Powders of raw material compounds (e.g. Y2O3, La2O3, BaCO3, SrO and CuO) for (Y, Ln)-(Ba, Sr)-Cu-O based superconductors are mixed at a suitable weight ratio according to the product composition and the obtained mixture is then calcined at 920-960 deg.C (e.g. for 2hr) in O2 atmosphere under 1-5atm., cooled at 100 deg.C/hr cooling rate and dried by heating at 100-150 deg.C. The resultant calcined substance is subsequently crushed into granules having 0.5-2.0mum particle diameter and pressed to provide a compact, which is then fired at 920-960 deg.C (e.g. for 6hr) in O2 atmosphere under 1-5atm. and cooled at 100 deg.C/hr cooling rate and subsequently dried by heating at 100-150 deg.C to afford the titled material.

Title: Mos integrated circuit with adjustable threshold value
Inventor: JIYASETSUKU KOBUARUSUKII
IPC: G11C11/56
Filed: 1990-07-20
Abstract: PURPOSE: To obtain an integrated circuit having a threshold value adjustable within a wide extent of a voltage by method, wherein the basic structure of an electrically erasable programming memory call is utilized. CONSTITUTION: High voltage is applied between a drain D and a gate G, whereby a charge passes through a silicon oxide layer in a tunnel window and is stored under a floating gate FG. Such a cell has a property executable for the storage of the charge, that is erase (a state '1' that a transistor is turned on with respect to a read voltage VL) of a call and removal (a state '0' that the transistor is turned off with respect to the read voltage VL) of the charge under the floating gate FG due to a programming of the cell. The storage of the charge is equivalent to an application of an initial voltage to the floating gate FG, and the characteristic curve IDS=F(VG) of the cell is moved. The charge, which is stored under the floating gate FG, is controlled. Thereby, the threshold voltage of a device can be accurately controlled.

Title: Air intake of centrifugal compressor
Inventor: TAKAMURA TOUSAKU
IPC: F04D29/42
Filed: 1981-12-02
Abstract: PURPOSE:To prevent surging in a compressor by furnishing two or more low guide vanes at the inside surface of the passage's outer walls just before the inlet to the impeller of a centrifugal compressor, by giving the stream at this inlet to impeller a mild swirling at its outer zones, and by preventing defoliation owing to distortion of the flow. CONSTITUTION:Two or more guide vanes 9, sufficiently low compared with the diameter of the passage, are installed on a circumference at the inner surface of a bell-mouth 3 forming a ring-shaped passage's exterior walls just before the inlet to impeller 1 projecting a little aslant with respect to the axis of a rotary shaft 2. Thereby the air stream taken in at the suction hole 5 is given by the guide vanes 9 a mild swirling only at the zone nearer the inside surface of bell-mouth 3 as exterior walls of ring-shaped passage A to lower the relative Mach number to the impeller inducer 8. Therefore defoliation owing to distortion of the flow is prevented to hinder the compressor from being put in the surging state. Thus the operating range of a centrifugal compressor can be widened.

Title: Bag filter
Inventor: INDO KENJI
IPC: B01D46/02
Filed: 1985-09-03
Abstract: PURPOSE:To improve work efficiency, by providing a suction draft fan equipped with a four-way changeover valve for exclusive use on the top of each dust collection chamber, allowing the delivery side of said fan to be opened to the atmosphere, and allowing back pressure to be applied at each dust collection chamber by the changeover of the valve. CONSTITUTION:In a suction draft, closed type bag filter 1, an induced draft fan 13 equipped with a four-way changeover valve is provided on the top of each dust collection chamber 2, with the delivery side of the fan opened to the atmosphere. During normal operation, the four-way changeover valve is changed over so as to draw in clean air in the dust collection chamber 2, whereas when the pressure drop increases as the dust accumulates on the inside surface of filter cloth, the inside of the dust collection chamber is made open to the atmosphere by changing over the changeover valve, whereby the air flows into said dust collection chamber, causing back pressure to act on the filter cloth, so that the dust falls down into the hopper. In such a manner as described above, back pressure is applied to each of the dust collection chamber independently; therefore, inspection, etc., can be conducted without stopping operation, resulting in an improved work efficiency.

Title: Method of drying
Inventor: II TOSHIHIRO
IPC: H01L21/304
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To dry a silicon wafer by removing humidity, remove water molecules from a silicon wafer surface having no oxide film, and simultaneously promote hydrogen termination of silicon atoms, by drying the semiconductor with inert gas that contains hydrogen radicals. SOLUTION: Hydrogen is added to inert gas to generate hydrogen radicals by using a heated metallic catalyzer to promote hydrogen termination after the drying. Usable catalyzer has a catalytic effect for the radical generation, for which nickel, platinum or the like are listed; however more preferable one in terms of the catalytic capability is platinum. In using the metallic catalyzer, its form preferably has as large surface area as possible, and a form of filter is preferable to increase effective contact area between the metallic catalyzer and hydrogen. The gas is required to be heated to approximately a temperature of blowing the wafer. The position of drying the wafer is preferably close to the point where the gas has just been released from the metallic catalyzer, because of short lifetime of the irradiating radicals.

Title: Sealant gun
Inventor: ANZAI TERUO
IPC: B65D35/28
Filed: 1993-08-04
Abstract: PURPOSE:To repeatedly use a cartridge of a sealant gun, where a sealant container bag filled with sealant is set in the cartridge and pushed by a plunger to squeeze the sealant out, much more times by restraining the sealant container bag from being caught in the gap between the cartridge and the plunger. CONSTITUTION:A sealant gun consists of a sealant container bag S where sealant is filled, a tubular cartridge in which the sealant container bag S is set, and a plunger P having eight notches K around the circumference at equal intervals. To force sealant out, the plunger P is pushed into the cartridge from the rear opening so that sealant flowing out of the sealant container bag S is squeezed out from a nozzle at the front end of the cartridge. When sealant is forced out, the sealant container bag S is smashed and becomes baggy, leaving some loose surplus. However, as the loose surplus escapes into the notches K, the sealant container bag S is not caught in the gap between the plunger P and the cartridge.
