  • Publication number: 20240139716
    Abstract: Provided is an exhaust gas purification catalyst providing a catalyst performance and an OSC performance at the same time even at low temperature. The present disclosure relates to an exhaust gas purification catalyst including a substrate and a catalyst coating layer coated on the substrate. The catalyst coating layer includes a first catalyst coating layer containing Pd and/or Pt and a second catalyst coating layer containing Rh. The first catalyst coating layer is formed from an end portion in an upstream side with respect to an exhaust gas flow direction in the exhaust gas purification catalyst. The second catalyst coating layer includes an upstream coating layer and a downstream coating layer. Rh in the upstream coating layer and the downstream coating layer are supported on specific carrier particles. Further, a particle diameter of Rh is controlled.

  • Publication number: 20240123880
    Abstract: A seat back panel includes a panel main body and a separate panel. The panel main body is disposed at a posterior portion of a seat back of a vehicle seat. The panel main body structures a portion of a main body portion of a seat back frame. An aperture is formed at a location of the panel main body that opposes a dorsal region of a seat occupant. The separate panel is attached to the main body portion and closes up the aperture. At a time of rear-end collision of the vehicle, the separate panel receives a load from the dorsal region of the seat occupant and relatively displaces toward the rear side of the seat back with respect to the panel main body.

  • Patent number: 4780434
    Abstract: A refractory composition which is suitable for forming a sliding gate to be used at the bottom of a ladle or tundish is provided. The refractory composition comprises 10 to 30 parts by weight of an alumina-magnesia spinel material containing 40 to 70% by weight of Al.sub.2 O.sub.3, 25 to 60% by weight of MgO and 10% or less of impurities, and 70 to 90 parts by weight of a magnesia material containing at least 90% by weight of MgO, wherein the composition contains 10 to 25% by weight of Al.sub.2 O.sub.3 and 75 to 90% by weight of MgO. 1 to 10 parts by weight of Al.sub.2 O.sub.3 material may be further added together with the alumina-magnesia spinel material and the magnesia material, to form the refractory composition.

  • Patent number: 4667858
    Abstract: A filler material for filling an outlet aperture of a casting ladle or similar container, comprising a particulate core principally composed of quartz and a coating layer which covers a surface of the core, the coating layer having a multiplicity of fine particles principally made of at least one material selected from materials of feldspar group can be surely taken off from the outlet aperture of a casting ladle or other similar container to allow substantially complete opening of the aperture when the slide gate is opened.

  • Patent number: 4632283
    Abstract: A molten metal discharging device comprising:a stationary plate adapted to be mounted at a bottom portion of a container accomodating molten metal, the stationary plate having a molten metal passage bore for permitting the molten metal from the container to be discharged therethrough, anda slide plate slidable along a lower face of the stationary plate and adapted to open or close the passage bore by being slidably displaced relative to the stationary plate, in whicha circumferential wall of the passage bore in the stationary plate is made of dense refractory material and the circumferential wall made of the dense refractory material has a plurality of gas supply holes therein for permitting a gas to be supplied into the passage borehas less fear that the passage bore thereof may be blocked by the solidification of the molten metal and/or deposition of metal oxides and has an improved resistance against corrosion by the molten metal.
