Abstract: A piercing and rolling plug has a film composed of oxides such as Fe3O4 and FeO and Fe (metal) as being formed on the surface of the base metal by electric arc spraying using an iron wire whose main component is Fe and, owing to this film, a plug excellent in heat-shielding and seizure-preventing effects can be realized and the lifetime of the plug can be prolonged. Further, in regenerating this plug, a film can be re-formed via the steps of shot blasting of the as-used plug in piercing and rolling and electric arc spraying in that order; thus, it is possible to regenerate the plug at low cost and in a short period of time.

Abstract: A fuel cell and a reformer are disposed above and in the vicinity of a horizontal straight line connecting the center of a front axle and the center of a rear axle of a motor vehicle. A fuel tank is disposed in a position above the fuel cell and the reformer. In the case of a fuel cell powered motor vehicle, e.g. a buggy classified as an All Terrain Vehicle (ATV), the drive shaft for transmitting power to the front axle and/or the rear axle can arranged without interfering with components of the fuel cell system.

Abstract: In a catalyst element for purifying exhaust gases having a metallic carrier and a catalyst carrying layer, an undercoat layer is formed by coating the surface of the carrier with a heat resistant inorganic oxide which is superior in adhesion to a metal. The catalyst carrying layer is then formed by carrying platinum (Pt) and rhodium (Rh) on an alumina layer. The catalyst carrier layer can thus be adhered in a close and better contact with the carrier via the undercoat layer. Even when the carrier is subjected to thermal expansion and vibrations, the amount of peeling of the platinum and rhodium off (or away from) the carrier can be minimized. Consequently, the decrease in the purifying characteristics can be minimized.

The metal flat sheet is welded, at each turn, to the metal corrugated sheet at a plurality of axially arranged welding positions on each portion where the metal flat sheet contacts the metal corrugated sheet. Letting L be the axial length of the honeycomb structure and D be the diameter of the honeycomb structure, the maximum value L1 of distances between adjacent welding positions satisfies at least one of relationships given by L1≦/D/2 and L1≦/L/2, or the distance L2 between the outermost welding positions in the axial direction of the honeycomb structure and the outer end face of the honeycomb structure satisfies at least one of relationship given by L2≦/D/20 and L2≦/L/10.

Abstract: A process for treating a high temperature corrosion resistant composite surface is disclosed. The process includes the steps of forming a first alloy layer by coating a metallic base material with a NiCr alloy or a MCrAlY alloy (M being made of one or more selected from the group consisting of Fe, Ni and Co) with low pressure plasma spraying, forming a second alloy layer on the first alloy layer by coating the first layer with an alloy having identical composition with atmospheric plasma spraying and then subjecting these layers to thermal diffusion treatment in a vacuum furnace or an inert gas atmosphere furnace. Thus, high temperature corrosion resistance is provided for a metallic material used at high temperatures.
