  • Patent number: 10159934
    Abstract: Provided is an exhaust gas purification catalyst that combines reduction of pressure loss and enhancement of purification performance. This invention provides an exhaust gas purification catalyst comprising a wall-flow-type substrate and first and second catalytic layers. The first catalytic layer is provided to the interior of a partition wall, in contact with an entrance cell, from an exhaust inlet-side end in the running direction, having a length L1 less than Lw. The second catalytic layer is provided to the interior of a partition wall, in contact with an exit cell, from an exhaust outlet-side end in the running direction, having a length L2 less than Lw. An internal portion of partition wall in contact with entrance cell has a substrate-exposing segment near the exhaust outlet-side end.

  • Patent number: 10125649
    Abstract: An exhaust gas purification catalyst that has an excellent exhaust gas purification performance while suppressing pressure loss increases. The exhaust gas purification catalyst is provided with a substrate having a wall-flow structure and having a partition; a first catalyst layer formed, in a region of an interior part of the partition that is in contact with an entrance cell, along the extending direction of the partition from an exhaust gas inflow-side end for less than the total length Lw of the partition; and a second catalyst layer formed, in a region of an interior part of the partition that is in contact with an exit cell, along the extending direction of the partition from the exhaust gas outflow-side end for less than the total length Lw of the partition. The first catalyst layer and the second catalyst layer are configured to partially overlap with each other in the extending direction.

  • Publication number: 20180133451
    Abstract: Levers (30) are connected to a base end portion (13) of a male luer via a base (15). Each lever includes a locking portion (31) and an operating portion (35). A locking claw (32) protrudes from each locking portion toward the male luer. A lock ring (8) is provided opposing inner surfaces of the operating portions. The lock ring is movable between a first position at which the lock ring is located close to the base and a second position at which the lock ring is located away from the base. When the lock ring is at the first position, the levers are pivotable such that the locking claws move away from the male luer. When the lock ring is at the second position, the lock ring restricts the levers from pivoting such that the locking claws move away from the male luer.

  • Publication number: 20180064923
    Abstract: A male luer (10) is surrounded by a hood (20). A lever (30) is connected to a base end portion (13) of the male luer via a base (15). The lever includes a locking portion (31) and an operating portion (35). A locking claw (32) protrudes from the locking portion toward the male luer. The locking portion is disposed in a cut-out (23) that is formed in the hood. The lever is elastically pivotable so that when an outer surface of the operating portion is pressed, the locking claw moves away from the male luer. When viewed along a central axis (3a), a connector main body (3) has a major axis (15a) in the direction in which the male luer opposes the lever.

  • Publication number: 20150265499
    Abstract: A puncture needle (10) protrudes from the center of an approximately cross-shaped top plate (20) from which four arms (21) are protruded. From the tip of each of the arms, two elastic pieces (22) divided by a slit (23) extend toward the same side as the puncture needle. The tips of the two elastic pieces extending respectively from two adjacent arms are joined via a bridging portion (24) so as to form an approximately U-shaped holding piece (25). An engaging claw (30) protrudes toward the puncture needle from the bridging portion of the holding piece. The engaging claw can be displaced in a direction away from the puncture needle by elastic deformation of the elastic pieces.

  • Patent number: 8551908
    Abstract: An exhaust gas purification catalyst includes: a lower catalyst layer that contains a ceria-zirconia mixed oxide having 50 to 70 mass % of CeO2 and 5 mass % or more of Pr2O3 and carries at least one of Pt and Pd; and an upper catalyst layer that contains at least zirconia and carries at least Rh, wherein the total amount of CeO2 per liter of the carrier base is 15 to 30 g. Because the amount of CeO2 is small, formation of H2S is suppressed and a high capability of adsorbing and releasing oxygen is brought out in spite of the small amount of CeO2.
