Title: Heat-resistant catalyst and catalytic combustion method using the same
Inventor: KAWAGOE HIROSHI
IPC: B01J23/56
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a catalyst prevented from the flocculation of noble metal particles even at high temp. and stable for a long time by dispersing a platinum group element on a heat-resistant catalyst carrier and further dispersing magnesium oxide on the platinum group element. CONSTITUTION:Oxide, carbide or nitride of a metal belonging to the Groups IIa, IIIa, IV of the Periodic Table such as alumina or silica is used as a heat- resistant inorg. carrier. A platinum group metal such as platinum, palladium or rhodium is supported on this carrier as a catalytically active component and magnesium oxide particles are further dispersed on the platinum element particles. By this method, since the flocculation of noble metal particles can be suppressed even at high temp., a combustion catalyst showing catalitic activity stable for a long time is obtained.

Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To easily clean pointed electrodes by arranging a corona discharge electrode projected from insulating members by separating tip parts of the pointed electrodes from each other and a cleaning member to clean the pointed electrodes. SOLUTION: When a screw 210 is rotated, a cleaning means 200 laterally moves in parallel in the lengthwise direction of pointed electrodes 10 according to the rotational direction of the screw 210 by a holder 201 screw fitted to this. In this case, pins (205a and b) arranged on two legs 202a and 202b are slidingly moved by using guide grooves 20a and 21a arranged in insulating members 20 and 21 as a guide, and a cleaning roller 203 moves in rotation while sticking in projecting parts of the pointed electrodes in parallel to the pointed electrodes 10. Therefore, the pointed electrodes are cleaned, and a stain such as toner and a discharge product material sticking to tip parts is removed. The cleaning means 200 needs not be necessarily moved by driving of a motor or the like, and the holder 201 may be manually moved.

Abstract: PURPOSE:To precisely inspect the surface of a viahole by determining a threshold value on the basis of the average value of parts excepting a viahole passing part and binarizing the height of a substrate at the viahole passing part on the basis of the threshold value. CONSTITUTION:The laser beam from a laser generating source 51 is reflected by a rotary mirror 55 through lens system 52, 53 and projected on a ceramic substrate 7 having a viahole 9 through a lens system 56 as shown by a scanning locus 8 while the reflected beam is detected by photomultiplier tubes 63A, 63B through a lens system 61 and a beam splitter 62 and operated by an operator 64 to become a height signal (b). The average value (h) of the height signal (b) of parts excepting a viahole passing part is calculated and a slice level imparting a tolerance value of + or -DELTAh above and below the average value (h) is set. When the height signal (b) is between h+ or -DELTAh, the viahole is judged to be normal and, when the height signal (b) is out of this range, the viahole is judged to be abnormal.

Filed: 1994-12-05
Abstract: PURPOSE: To provide a soldering iron by which chip parts in various sizes are removed with one soldering iron by forming a soldering iron tip in a frame shape, moreover, in an elastically deformable and spiral shape. CONSTITUTION: While heating the spiral shaped soldering iron tip 13 of a soldering iron 11 to 250 to 260 deg.C, the soldering iron 11 is lowered from the upside of a chip part. When the size of the chip part is smaller than the insidemost frame size of the spiral shaped soldering iron tip 13, since the chip part enters perfectly the inside of the soldering iron tip 13 and it is simultaneously heated from four sides to melt solder, the chip part can be removed from a substrate. When the chip part is larger than a frame size formed by the insidemost frame of the spiral shaped soldering iron tip 13, the insidemost frame of the soldering iron tip 13 is caught by the chip part.  However, since the soldering iron tip 13 is made of an elastically deformable material, a frame existing on the outside of the insidemost frame is extended and dropped around the chip part, the chip part is simultaneously heated from four sides, and solder is melted.

Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To effect the solid state polymerization of even polyester chips having a low melting point in good productivity by carrying out the polymerization under conditions in which the volume of chips packed into a polymerizer is specified times as large as that of the chips in a settled state. SOLUTION: A nitrogen gas is continuously fed into a vertical solid state polymerization tower 1 from an inlet 6, and starting polyester chips are metered and introduced into the tower 1 from an inlet 2, while an agitator shaft 4 having a plurality of agitating blades 5 is being rotated. The flow rate of the nitrogen gas fed is regulated so that the chips may be floated to such an extent that the volume of the chips packed is 1.03 to 1.18 times as large as that of the chips in a settled state. The temperature of the nitrogen gas is slowly raised so as to heat the polyester chips at a rate of 0.3 deg.C/min or below within the range of from Tg-5 deg.C to Tg+5 deg.C to prevent their fusing. After a specified temperature is reached, heating is continued until a specified degree of polymerization is reached. After the specified polymerization is reached, the above inert gas is changed into a cooling gas to cool the chips. The cooled chips are then withdrawn from the polymerizer.
