Title: Production of alumina-zirconia double oxides powder
Inventor: ISHIMARU HIROHISA
IPC: C04B35/48
Filed: 1988-10-04
Abstract: PURPOSE:To obtain the uniformly dispersed alumina-zirconia double oxides powder by adding a dispersant into the neutral slurry of alumina-zirconia, stirring the mixture with a ball mill, further finely dispersing the slurry and subjecting the slurry to spray drying. CONSTITUTION:Water and acidic dispersion such as acetic acid are added to zirconia powder and alumina powder and the mixture is stirred with the ball mill until the pH attains 2 to 4. The aq. ammonia or/and ammonium carbonate are mixed with the acidic slurry of the alumina-zirconia to produce the neutral slurry of the alumina-zirconia. Further, the dispersant such as ammonium polyacrylate salt is added to the neutral slurry of the alumina-zirconia and the slurry is stirred in the ball mill. Further, the slurry is finely dispersed by an attriter mill, etc., and is subjected to spray drying, by which the double oxides power is obtd. The reason for adding the alkaline dispersant to the slurry in the above-mentioned manner is to obtain the multiple body uniformly dispersed with the alumina and the zirconia as there is difference in delfocculating pH between the alumina and the zirconia in an alkaline region and the complete deflocculation of the slurry of the alumina-zirconia does not, consequently, take place.

Title: Exhaust gas purifying device for internal combustion engine
Inventor: JIYOZE SEUSO MARUGONATO RIBEIR
IPC: F01N13/02
Filed: 1992-09-21
Abstract: PURPOSE:To prevent lowering of exhaust gas purifying capacity owing to a moisture content in an adsorbent by locating an adsorbent in a bypass passage situated upper stream from a catalyst, limiting the opening of a flow passage switching valve when an exhaust gas temperature on the adsorbent outlet side is below a set value during the starting of the purge of the adsorbent, and promoting a purge through maximization of a flow rate on the bypass side when it exceeds the set value. CONSTITUTION:A pre-catalyst 4 and a main catalyst 5 are disposed in the exhaust gas passage 3 of an engine body 1, a bypass passage 7 is formed at a main passage 3A running therebetween and an adsorbent 6 is located in the bypass passage. The exhaust gas temperature on the inlet side of the catalyst 5 is inputted from a first temperature sensor 10 to a control unit 12. When it is decided that the exhaust gas temperature is an active temperature, the exhaust gas temperature on the outlet side of the adsorbent 6 is inputted by means of a second temperature sensor 11. When the inputted exhaust gas temperature exceeds a set value, it is decided that an adsorption moisture content is vaporized and flow passage switching valves 8 and 9 are brought into an opening through which purge operation is maximized. When it is below the set value, a flow rate to the bypass passage 7 is reduced through control of the flow passage switching valves 8 and 9 to reduce the influence of a moisture content. This constitution causes prevention of lowering of exhaust gas purifying capacity.

Abstract: PURPOSE:To oxidize and remove the phosphorus contained in a molten steel subjected to refining by decarburization by putting the molten steel into a ladle, if the content of P therein is above the specified value, then inserting an immersion pipe into the part from which molten slag is removed by blowing an inert gas, adding a dephosphorizing flux to the molten steel and subjecting the molten steel to oxygen blowing. CONSTITUTION:The molten steel 3 is put into the ladle 1 if the content of P in the molten steel after refining is above the specified value and is not accepted in terms of compsn. The inert gas is then blown through a bottom tuyere 2 of the ladle and the molten slag 3a on the surface of the molten steel in raised part is removed as the inert gas rises. The immersion pipe 4 made of refractories is immersed partly into the molten steel 3 in the part where the molten steel surface is exposed after the removal of the molten slag. Oxygen is blown to the molten steel from a lance 5 provided in the upper part of the immersion pipe and at the same time a basic flux such as quicklime or fluorite is added from a storage tank 7 to the molten steel surface by a chute 8. The basic dephosphorized slag contg. iron oxide of >=15% T, Fe is formed to oxidize the phosphorus in the molten steel and to fix the same into basic slag. The molten steel is thus dephosphorized and refined.

Title: Wire bonding method
Inventor: MIURA HIROSHI
IPC: H01L21/60
Filed: 1989-09-28
Abstract: PURPOSE:To enable discharge under the same condition before and after the exchange of a capillary, and stabilize the diameter of a ball to be formed, by determining the optimum position of the capillary at the time of discharge, on the basis of the contact position or the relative movement amount of the capillary and a setting member. CONSTITUTION:After a capillary 25 is mounted on an arm 23 positioned at the origin, a torch electrode 26 is moved on the moving locus of the capillary 25. The capillary 25 begins to descend toward the torch electrode 26 by the command from a controlling equipment 29. When the capillary 25 comes into contact with the torch electrode 26, it is detected by a contact detector 28. From this detection signal, the value (b) of the moving amount from the origin position to the point where the capillary 25 comes into contact with the torch electrode 26 can be detected. The controlling equipment 29 delivers the value (b) and the optimum distance (a) for discharge previously stored in a storing part 31 to an operating part 32, which calculates the difference (c). In a process that discharge is generated between a wire and the torch electrode 26, the position of the capillary 25 is set to be a position lower by the value (c) than the origin position. In this state the discharge is generated, thereby forming a ball at the wire tip.

Title: Deodorizing apparatus in food storage shed
Inventor: KAMEI YASUHIRO
IPC: F25D23/00
Filed: 1989-09-27
Abstract: PURPOSE:To make it possible to easily supply air including constituents of an offensive small into a deodorizing apparatus and to sufficiently deodrize the air by arranging an ozonizer, an ozone decomposing device and a fan in such an order downstreamly from an upstream portion of a vent passageway in the vent passageway and providing a trap in the vent passageway so as to cause the ozonizer to be positioned in the upper portion of the vent passageway of the ozone decomposing device. CONSTITUTION:An offensive smell of foods disposed on a shelf 14 of a foods storage shed 12 is generally heavier than air, thereby falling downwardly, and the offensive smell enters the deodorizing apparatus 17 through an inlet port 16-1 and is guided to a trap by a first vent passageway 17-1. Then a high voltage is applied to an ozonizer 19 by a high voltage source 18 to generate the ozone which causes the offensive smell to be oxidized and decomposed. Air from which the offensive smell is eliminated by the ozonizer 19 is discharged from the vent passageway through an outlet port 16-2 in the storage room of the foods storage shed 12 by a fan 21 by way of an ozone decomposing device 20 which decomposes surplus ozone into oxygen, and a second vent passageway in such an order.

Title: Exposure device
Inventor: IWAMOTO KAZUNORI
IPC: H01L21/027
Filed: 1988-10-05
Abstract: PURPOSE:To enhance a uniformity of an exposure line width and to enhance an overall overlapping accuracy by a method wherein a means which corrects a posture of an ligner with reference to an external standard in real time is installed at a vibration-removing mechanism of the exposure device. CONSTITUTION:During an exposure sequence, a distance between a displacement meter 13 and a target 14 is always measured; when the distance deviates from a preset range, it is fed back to a vibration-removing unit 7 and is servo-locked within the preset range. A feedback system sets a solenois valve 30 to a closed state and a solenoid valve 29 to an open state by using a controlling circuit 35, e.g., when a gap between the target 14 and the displacement meter 13 is widened; it instructs a drive circuit 36 about an opening area of an electropneumatic proportional valve 31; it actuates three vibration-removing units independently; it acts so as to set the distance between the displacement meter 13 and the target 14 at the preset range. A surge tank 32 prevents a hunting phenomenon of the vibration-removing units; speed controllers 33, 34 are used to set a servo gain of a delivery and evacuation system. Thereby, an overall overlapping accuracy and a uniformity of an exposure line width can be enhanced.
