    Abstract: A honeycomb body, which is composed in such a manner that a strip of corrugated foil made of heat-resistant stainless steel containing aluminum and a strip of flat foil made of stainless steel are alternately wound or laminated on each other, is incorporated into an outer cylinder made of metal and integrated into one body by means of diffusion bonding, so that a diffusion bonded metallic catalyst carrier can be formed. Surface roughness of the strip of foil after the completion of diffusion bonding is 0.001 to 2.0 µm when it is expressed by center line average height Ra, and no sintered bridges are formed at both end portions of the diffusion bonded section in the longitudinal direction. The catalyst carrier is manufactured in a condition so that λb, which is defined by λb = 6.8 × 10 -12 × δf -1 × F 1/2 × Ra -1/2 × T 1/4 × exp(15000/T) × b 1/2 , can be in a range from 8 to 20 where thickness of the strip of foil is δf (m), average roughness of the foil surface is Ra (m), back tension in the case of winding is F (kgf), contact width of the piece of flat foil with the piece of corrugated foil is b (m), heat treatment temperature is T (K), and degree of vacuum is Pout (Pa), under the condition that 7.52 x 10 9 × exp(-35000/T)≥ 8 × Pout.

    Abstract: The present invention relates to a catalyst comprising a honeycomb (1) and a surrounding jacket, the honeycomb comprising a structure formed of a stack of metal sheets, of which at least part are profiled, and the honeycomb structure including several through-flow channels for gas. The free ends of the said metal sheets are distributed over a part (S 1 ) of the honeycomb periphery unsymmetrically to the centre of the honeycomb so that part (F 1 ) of the honeycomb's periphery is free from the free ends of the metal sheets. The said honeycomb is attached either directly or through an intermediate layer to the said jacket over an area (L 1 ) comprising at least part of the said free ends.

    Abstract: A metal carrier and a production method thereof for carrying an exhaust gas cleaning catalyst for automobiles, autobicycles, and industrial equipment. The metal carrier includes a metal honeycomb core body pressed into a metal outer cylinder, and the joined portion of the a flat plate and a corrugated plate forming the metal honeycomb core body includes a solder material coated in spots or stripes at peaks of corrugation of the corrugated plate. The solder material in the joined portion of the flat plate and the corrugated plate has a thickness of less than 100µm, the positions of the joined portions are different between the surface and backside of the flat plate and corrugated plate, and the joined portions are present through an unjoined area having a length of more than 5% of the length of the metal honeycomb core body from an end face of the metal honeycomb core body at the exhaust gas inlet side. The joined portion of the outer periphery of the metal honeycomb core body and the inner surface of the metal outer cylinder is a plurality of stripes. The joined portions of the flat plate and the corrugated plate of the outermost periphery of the metal honeycomb core body and the metal outer cylinder are not in line with each other, and the metal honeycomb core body and the metal outer cylinder are joined intermittently in the axial and peripheral directions. In a production method of the metal carrier, the metal honeycomb core body is pressed into the metal outer cylinder while the slurry-formed solder material coated at peaks of the corrugated plate maintains a fluidity and the solder material coated on the inner wall surface of the metal outer cylinder has no fluidity.

    Abstract: A method for manufacturing vehicle structural bodies in which highly reliable vehicle structural bodies can be manufactured using laminated panels. The method comprises the steps of positioning a plurality of honeycomb panels relative to each other so as to hold them together for weld joining, and confirming joint conditions between materials constituting honeycomb panels by inspecting the weld joint portions and the vicinity of welding lines using non-destructive inspection methods such as radiation, ultrasonic, impact and hammering inspection methods.
