Abstract: In a method for working the end portion of a roof molding for use in an automobile, at desired position on the molding surface 32 of a pressing mold 31 that faces a cut-away portion 21 formed on the back surface of the end portion 12 of the roof molding, there is formed a pressing projecting portion 33 which extends along the width direction of the end portion 12. In a pressing operation after the end portion 12 is heated and softened, the cut-away portion 21 of the back surface of the end portion 12 is pressed and deformed by the pressing projecting portion 33 of the pressing mold 31 to thereby form a mounting and fixing projection portion 22 which projects toward at least one side in the width direction of the end portion 12.

Abstract: A catalyst for methanol synthesis and reforming which is constituted of copper, zinc, and aluminum oxides and has a structure comprising copper or copper oxide particles covered with a film of aluminum oxide and zinc oxide. The copper or copper oxide particles preferably have a particle size of 1 to 100 nm. The film of aluminum oxide and zinc oxide preferably has a thickness of 0.1 to 100 nm. The proportions of the copper, zinc, and aluminum elements are 68.0 to 86.0% by weight, 4.5 to 21.0% by weight, and 2.0 to 20.0% by weight, respectively. The foregoing highly active catalyst comprising copper, zinc, and aluminum oxides can be obtained not by a costly special technique but by the coprecipitation method, which is the most common process for catalyst production, without using any additive element.

Abstract: A catalyst for methanol reforming which consists of an alloy represented by the general formula TM, wherein T is at least one element selected from the group consisting of Ti, Zr, Hf, Y, Nb and Zn; and M is at least one element selected from the group consisting of elements (Cu, Ag and Au) belonging to group IB of the periodic table and elements (Fe, Co, Ni, Ru, Rh, Pd, Os, Ir and Pt) belonging to group VIII of the periodic table, said alloy having a surface comprising an oxide including the element T and, dispersed therein, fine metal particles composed of the element M. The catalyst is produced by preparing an alloy having an amorphous phase and/or a microcrystalline phase from a molten composition of TM, and subsequently heating the alloy at 50.degree. to 700.degree. C. in an oxidizing atmosphere or an atmosphere like that in which methanol reforming is performed. Using the catalyst, methanol reforming can be efficiently performed at relatively low temperatures.

Abstract: A fast and brightly colored oxide film of aluminum which excels in durability and allows no separation of pigment is produced by using an aqueous dispersion of an organic pigment or carbon black finely divided to a size in the range between 3 and 150 nm, forming on a surface of an aluminum member an anodic oxide film containing pores larger in diameter than the ordinary pores, and causing the organic pigment or carbon black to migrate and deposit in the pores of the oxide film by means of electrophoresis. The formation of the anodic oxide film containing the pores larger in diameter than the ordinary pores is accomplished in the first method by subjecting the aluminum member to anodic oxidation at a high voltage in an aqueous solution of acid.

Abstract: Durable and clear blue color of freely controlled density can be expeditiously and efficiently impated to an anodic oxide film of aluminum by a method which comprises forming the anodic oxide film on the aluminum or aluminum alloy, then subjecting the aluminum or aluminum alloy to AC electrolysis in a bath containing an inorganic ferrous salt as a main component thereof thereby inducing deposition of iron in the pores of the oxide film, and subsequently placing the aluminum or aluminum alloy as an anode in a bath containing hexacyano iron (II) acid salt as a main component thereof and subjecting the same to DC electrolysis therein. In the alternative method, the pore-widening treatment is added next to said step of anodic oxidation. The pore-widening treatment is effected by immersing the aluminum or aluminum alloy in sulfuric acid or phosphoric acid or electrolyzing the same in phosphoric acid or a mixed solution of phosphoric acid and sulfuric acid.

Abstract: An aluminum or aluminum alloy material is subjected to anodic oxidation, then to a treatment of electrophoresis in a bath containing a hexacyanoferrate (II) or hexacyanoferrate (III), and subsequently to a treatment of immersion in a bath containing at least one metal salt selected from the group consisting of salts of Fe, Ni, Co, Cu, Zn, Cd, Ba, Tl, and Mg and at least one electrolyte selected from the group consisting of sodium sulfate, potassium sulfate, sodium chloride, and potassium chloride. Consequently, a coloring compound formed by the reaction of the aforementioned hexacyanoferrate (II) or hexacyanoferrate (III) with the aforementioned metal salt is deposited in the receding parts of micropores of an anodic oxide coating, with the result that the aluminum or aluminum alloy material is endowed with a durable color.

Abstract: The present invention provides a process for producing a perovskite-type oxide catalyst. The process comprises the steps of reacting an aqueous solution containing plural metal salts, such as chloride, sulfate, nitrate, etc., and an aqueous solution of a neutralizer such as alkali carbonate, alkali hydroxide, ammonia, etc., so as to cause coprecipitation of neutral salts and firing the coprecipitated salts to provide a perovskite-type oxide. At least one organic substance selected from the group consisting of cellulose, polyvinyl acetate, polyethylene, polystyrene, polypropylene, polyvinyl alcohol, starch, gelatin and saccharide is added prior to the firing step. The addition of the organic substance makes possible the attainment of a highly active perovskite-type oxide catalyst composed of very fine particles (primary particles).
