摘要： PURPOSE:To absorb thermal stress caused by temperature difference in a honeycomb part and to obtain a catalyst which is not broken by thermal fatigue by shaping a wavy foil to be a wavy shape having bending parts. CONSTITUTION:A bending part B is formed between joining points A and C of platy foils 1, 3 and a wavy foil 2. A bending part D bent in the opposite direction of the part B is formed between the joining point C and neighboring joining point E and thus a nonsymmetrical trapezoidal shape is formed by repeating formation of bending parts in this way. The length A-B-C of the wavy foil is made sufficiently long against the distance between the joining points A, C. With this structure, a catalyst having enough durability to high temperature and high speed exhaust gas flow and high resistance to thermal fatigue even when temperature difference is caused between a honeycomb part and an outer cylinder is obtained.

摘要： PURPOSE:To obtain a metallic carrier having high bonding strength of honeycombs by producing a one sided Al clad steel foil by cold rolling an Al plate on one side of a steel sheet, corrugating the Al clad steel foil, then forming a honeycomb body by winding together with a flat plate foil superposed thereon, and inserting the honeycomb body into an external cylinder. CONSTITUTION:A steel sheet coil 1 and an Al coil 2 are uncoilded on a reel 6, and an Al plate is bonded to one side of the steel sheet with a rolling mill 4 for cold rolling to form thus a one sided Al clad steel sheet 5, and wound around a coiler 7. The product is then rolled to 30-100mum thickness, and corrugated between a corrugating roll 10, then worked to form a honeycomb body on a honeycomb working machine together with a clad foil 12 which is a flat sheet superposed on the corrugated clad foil 7 as it is. In this stage, an Al surface of the one sided clad foil is arranged to come to an external peripheral side of the honeycomb body. Then, the honeycomb body is inserted into a heat- resisting steel pipe 15, and heat-treated at 1100-1300 deg.C for >=3min under nonoxidizing condition. Thus, a carrier causing no expansion of clearance is obtd.

摘要： PURPOSE: To economically avoid an edge rupture by making a coefficient of friction between the surface of a rolling roll coming into contact with the side edge of a metallic plate and the metallic plate lower than that of the center part. CONSTITUTION: A metallic plate S is rolled by work rolls 1. For instance, the surface roughness Ra of a range A is set to 0.90μm, the surface roughness Ra of a range B to 0.45μm, and the width (e) of the side edge of a steel strip to 100mm. The enlargement of a crack does not occur on the steel strip cold- rolled in this way. That is, a rolling is performed after making a coefficient of friction between the side edge of a width of 5 to 300mm including the edge of the metallic plate S and the surface of a rolling roll 1 coming into contact with this side edge lower than a coefficient of friction in the center part except the side edge. Rolling mill lubricant more than that of the center part is supplied on the side edge. Also, the rolling mill lubricant with a concentration higher than that of the center part is supplied to the side edge. Consequently, the productivity of the rolling can be improved.

摘要： PURPOSE:To orientate discontinuous fibers to one direction and contrive to ensure mechanical strength, which is high in the direction of orientation, by a method wherein the shape of each one of drain ports, which are arranged below mesh belt is specified when the mixed layer of discontinuous fibers and thermoplastic resin is produced on the mesh belt in paper making manner by draining the liquid in foaming liquid dispersion through the mesh belt and the drain ports. CONSTITUTION:Discontinuous fibers, thermoplastic resin and the like are dispersion-mixed with foaming liquid such as water added with surface-active agent or the like in a dispersion tank 1. The foaming liquid dispersion is passed through a head box 2 and caught on the mesh belt 3 in paper making manner. The liquid in the foaming liquid dispersion is drained through the mesh belt 3 and drain ports 4, which are installed below the mesh belt 3, by vacuum. The drain port 4 is opened parallel to the traveling direction of the mesh belt 3. The width 5 of each opening is less than the length of the discontinuous fiber. The number of slits is provided so as to correspond to the width of the mesh belt 3. After the liquid in the foaming liquid dispersion is drained, the mixed layer of the discontinuous fibers and the thermoplastic resin is dried with a dryer 6 and, when necessary, pressed with a hot press 7, resulting in forming in dense sheet.
