  • Publication number: 20140311616
    Abstract: A structure includes a base material made of metal to be in a form of a tube and a surface coating layer provided on an inner face of the tube. The surface coating layer includes a first layer provided on the inner face and a second layer provided directly or indirectly on the first layer as an outermost layer of the surface coating layer. The first layer contains an amorphous inorganic material. The second layer contains a crystalline inorganic material having a softening point of about 950° C. or higher.

  • Publication number: 20140127086
    Abstract: An exhaust gas processing device includes a first cylindrical metallic member, an inorganic mat member, a second cylindrical metallic member, and an insulating layer. The inorganic mat member is wound around an outer periphery of the first cylindrical metallic member. The second cylindrical metallic member accommodates the first cylindrical metallic member around which the inorganic mat member is wound. The insulating layer have a thickness of about 20 ?m to about 400 ?m and is provided at at least one of a first part which is an inner surface of the first cylindrical metallic member, a second part between an outer surface of the first cylindrical metallic member and the inorganic mat member, and a third part between an inner surface of the second cylindrical metallic member and the inorganic mat member.

  • Publication number: 20120186239
    Abstract: A holding sealing material includes an inorganic fiber sheet having inorganic fibers interlaced with one another, and a water-proof insulation sheet containing a flaky inorganic material. An electrically heating exhaust gas purifying apparatus includes an exhaust gas-treating body made of a resistance heating body, a metal casing to house the exhaust gas-treating body and a holding sealing material. The exhaust gas purifying apparatus includes a first electrode and a second electrode. The first and second electrode each penetrate through the metal casing and the holding sealing material, and have a first end part bonded to the exhaust gas-treating body and a second end part exposed outside of the metal casing. The holding sealing material includes an inorganic fiber sheet which has inorganic fibers interlaced with one another, and a water-proof insulation sheet containing a flaky inorganic material.

  • Publication number: 20120177540
    Abstract: An exhaust gas processing device includes a honeycomb structure in a pillar shape including a honeycomb unit, a catalytic agent, an inorganic mat member, a cylindrical metallic member and an insulating layer. The honeycomb unit includes cell walls to define a plurality of cells which extend from a first end of the honeycomb unit to a second end of the honeycomb unit along a longitudinal direction. The catalytic agent is provided on the cell walls. The inorganic mat member is wound around an outer peripheral surface of the honeycomb structure. The cylindrical metallic member accommodates the honeycomb structure around which the inorganic mat member is wound. The insulating layer has a thickness of about 20 ?m to about 400 ?m and is densely formed. The insulating layer is provided between an inner surface of the cylindrical metallic member and the inorganic mat member.
