  • Publication number: 20220314250
    Abstract: A method for manufacturing a pillar-shaped honeycomb structure filter including; attaching ceramic particles to a surface of the first cells by ejecting an aerosol including the ceramic particles toward the inlet side end surface from a direction perpendicular to the inlet side end surface while applying a suction force to the outlet side end surface to suck the ejected aerosol from the inlet side end surface, wherein the ejection of the aerosol is carried out using an aerosol generator including a drive gas flow path for flowing a pressurized drive gas, a supply port provided on the way of the drive gas flow path and capable of sucking the ceramic particles from an outer peripheral side of the drive gas flow path toward an inside of the drive gas flow path, and a nozzle attached to a tip of the drive gas flow path and capable of ejecting the aerosol.

  • Publication number: 20220314154
    Abstract: A pillar-shaped honeycomb structure including a plurality of first cells extending from an inlet side end surface to an outlet side end surface, and a plurality of second cells extending from the inlet side end surface to the outlet side end surface, with a porous partition wall interposed therebetween, wherein a porous film having a porosity higher than that of the partition walls is provided on a surface of each of the first cells, and at a cross-section orthogonal to the direction in which the first cells of the pillar-shaped honeycomb structure filter extend, the average thickness of the porous film in the central portion is larger than the average thickness of the porous film in the outer peripheral portion.

  • Patent number: 10981601
    Abstract: In an impact-absorbing member which extends in a vehicle length direction of an automobile and whose both end portions in the vehicle length direction have a collision-side end portion and a non-collision-side end portion whose positions become mutually different when seen from the vehicle length direction, an outer member and an inner member of the impact-absorbing member are formed so that a position of a gravity center at the collision-side end portion and a position of a gravity center at the non-collision-side end portion become mutually different according to a positional relationship between the collision-side end portion and the non-collision-side end portion in order to suppress a tensile stress generated at the collision-side end portion and suppress a compressive stress generated at the non-collision-side end portion in a collision.

  • Patent number: 10427633
    Abstract: [Object] To improve load resistance performance in response to collision. [Solution] An end structure of a vehicle according to the present invention includes: a beam 2 that extends in a vehicle width direction; and a connecting structure 3 that connects the beam 2 to a vehicle body frame. In a cross-sectional view perpendicular to the vehicle width direction, the beam 2 includes a first top surface part 2a and a first bottom surface part 2b which face each other, a first side surface part 2c that connects one ends of the first top surface part 2a and the first bottom surface part 2b, and first flange parts 2d that are formed to protrude vertically outwardly at the other ends of the first top surface part 2a and the first bottom surface part 2b.

  • Publication number: 20170333972
    Abstract: A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material, and a press working step of performing press working on the starting material by using a punch, and a pad and a die that are paired with the punch. The press working step includes a first step of forming, by the punch and the pad, the entire region of a top panel part, the entire region of each of a ridge line parts including the shape-changing part, and a region up to a predetermined height from the border between a vertical wall part and the ridge line part of a region of each of the vertical wall parts, and a second step of forming, subsequent to the first step, by the punch and the die, the remaining regions with the starting material sandwiched between the punch and the pad.
