Title: Microencapsulated alkaline earth metal sulfide phosphor
Inventor: YOKOYAMA TAIICHI
IPC: C09K11/08
Filed: 1987-01-19
Abstract: PURPOSE:To prevent the reduction in luminance due to hydrolysis in a water- base binder, by covering the surface of a sulfide phosphor with ethylcellulose and then with a nonionic surface active agent. CONSTITUTION:The surface of a sulfide phosphor made of a matrix comprising, e.g., calcium sulfide, magnesium sulfide or strontium sulfide is covered with ethylcellulose preferably having an ethoxyl group content of 43% or higher and a viscosity of 10wt.% solution of 50cp or higher. This surface is further covered with a nonionic surface active agent (e.g., a polyoxyethylene alkyl ether) to give an objective microencapsulated alkaline earth metal sulfide phosphor. This technique can improve the hydrolysis resistance of a phosphor without deterioration of the dispersibility in a water-based binder. These two layers of covering films are completely decomposed and removed by evaporation in a baking process.

Title: Oxygen top blowing steel making method using converter non-combustion exhaust gas
Inventor: HIRAI MASAZUMI
IPC: C21C5/40

Abstract: PURPOSE:To prevent molten steel from absorbing N2 or the calorie of exhaust gas from decreasing by blowing gas by removing the dust and moisture from the non- combustion recovery exhaust gas of the oxygen top blowing converter and using said gas in stirring the molten steel by the gas blowing from the furnace bottom in said converter. CONSTITUTION:Oxygen is blown from the lance 3 in an oxygen top blowing converter 1 to oxidize and refine molten iron to molten steel. At this time, the exhaust gas generated from the converter is collected in a hood 4 and is once stored in an exhaust gas holder 7 through a cooling and dust collecting unit 5 and suction- blower. The exhaust gas is passed through a heat exchanger 8 and a dehumidifier 9 to be dried, after which it is heated in the heat exchanger 8, thence it is pressurized to about 5-10kg/cm<2> and is blown through the bottom blowing port 2 such as of porous nozzle into the molten steel to stir the molten mix. Since no Ar gas is used, it is economically low in cost and since N2 in the exhaust gas is less, the decrease in calorie owing to nitrogen adsorption of the molten steel or dilution in CO amount does not occur.

Title: Resin coating formation on container using projection coating
Inventor: NISHIDA HIROTAKA
IPC: B32B1/02
Filed: 1979-01-29
Abstract: PURPOSE: To provide well-defined boundary line in resin coating by a method wherein air is continuously projected through small gap between container outer surface and annular type masking member and synthetic resin is coated by projection on the surface of container facing the projection side.  
     CONSTITUTION: Air with proper pressure is projected through gap 8 between outer peripheral surface of tube 1 such as aluminum and annular covering member 4. At the same time, synthetic resin material is projected from jet nozzle 9 that is vertically moving onto the shoulder and upper surface of tube 1 so that coating is performed. The projecting air through the gap 8 prevents molten resin from sagging through the gap 8. This further minimizes resin deposition of resin on the part of the masking member 4 near the tube shoulder. When resin is deposited, the gap 8 helps to prevent resin from adhering to tube 1 at next coating operation. Thus, well- defined boundary line A can be formed on coated layer 3.
