Title: Denitration of exhaust gas
Inventor: HOSONO YUKIO
IPC: B01D53/34
Filed: 1978-03-22
Abstract: PURPOSE: To enhance denitration ratio of NO x -containing exhausted high temperature gas without causing second pollution such as NH 3 , a small quantity of urea solution is injected into the exhaust gas, mixed, cooled, and maintained at cooled condition for a period of specified time.  
     CONSTITUTION: Exhaust gas is heated to 700 to 1100°C at zones of the prebank 2 or the fire furnace 12 surrounded by walls of water cooling, boilder evaporator pipes 1. Into such high temperature gas zone, aqueous urea solution 13 in a quantity of 0.3 to 3 times mole of NO x  is sprayed from pipe 7 by compressed air to be distributed uniformly in the cooler bank zone 3. Next, the gas passes through the gas cooling zone having sufficient number of heat conductive pipes to cool the gas to 300 to 430°C at the outlet of the cooling bank 3. Next, the gas is admitted into the cooling chamber 4, where the gas is maintained at such cooling temperature for a period of more than 0.1 second. Then the gas passes through the afterbank 5 and exhausted from the flue 6.

Title: Manufacture of barium titanate semiconductor ceramic
Inventor: GOTO TAIJI
IPC: H01C7/02
Filed: 1992-02-19
Abstract: PURPOSE:To obtain a sufficient withstand voltage and PTC characteristic by weighing materials in the same composition as a desired composite, heat-treating the materials at a temperature below the regular calcining temperature, grinding the material mixture, adding a specific quantity of it to materials of the desired composite mixing them, grinding, granulating, molding and calcining the resultant mixture. CONSTITUTION:Materials of barium titanate semiconductor ceramic are weighed. The same materials are weighed in the same composition as the composite, and heat-treated at a temperature of approx. 1000-1300 deg.C, a temperature below the regular calcining temperature. Then the materials are ground to obtain tentatively calcining powder. Approx. 5-40wt.% of the tentatively calcining powder is added to the materials previously weighed, and mixed. The resultant mixture is ground again, granulated, molded and regularly sintered. This remarkably improved the withstand voltage, realizing light-weight thin semiconductor ceramic and enabling high voltage applications.

Title: Metal mold for casting, excellent in erosion resistance
Inventor: SERA TOMOAKI
IPC: B22D18/04
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To improve erosion resistance while maintaining high temperature strength, ductility, and toughness by forming an oxide layer of Fe-Cr of specific thickness on the surface of a steel having a specific composition consisting of C, Si, Mn, Cr, Al, and the balance Fe with inevitable impurities. SOLUTION: The metal mold is obtained by forming an oxide layer of Fe-Cr of 1-30 μm thick on the surface of a steel having a composition consisting of, by weight, 0.1-0.4% C, 0.1-0.7% Si, 0.1-1.5% Mn, 8.0-13.0% Cr, 0.01-3.0% Al, and the balance Fe with inevitable impurities. It is preferable that the contents (wt.%) of Cr and C in the steel satisfy the relation of Cr=16%±1-30×C+30 deg.C2. When oxidation treatment is performed after metal mold manufacture, the resultant oxide film becomes a spinel-type oxide of Fe-Cr if a large amount of Cr is contained in the steel, and a reaction with molten Al alloy can be suppressed by this film, by which erosion can be reduced.
