Patent number: 11370053Abstract: An aspect of the present disclosure provides a welding torch that includes a torch head and a torch body removably connected to the torch head. The torch head includes first and second torch-head flow paths for flowing cooling water, first and second inlets/outlets communicating with the first and second torch-head flow paths, respectively, and a movable part movable in an axial direction of the torch head. The torch body includes a torch-body flow path for flowing cooling water, and first and second connection ports communicating with opposite ends of the torch-body flow path, respectively. The first and second inlets/outlets communicate with the first and second connection ports, respectively, when the torch head and the torch body are connected to each other. The first and second inlets/outlets are closed with the movable part when the torch head and the torch body are separated.Type: GrantFiled: May 10, 2018Date of Patent: June 28, 2022Assignee: DAIHEN CorporationInventors: Tetsushi Minamoto, Yukiya Morita, Yoshiaki Fukunaga

Patent number: 11370052Abstract: An arc welding system of a consumable electrode type comprises: a wire feeding device that feeds welding wire from a wire feeding source to a welding torch; and a power supply device that supplies electric power between the welding wire fed to the welding torch and a base material, the system being configured to weld the base material by arc generated by the supplied electric power. The wire feeding device is provided with: an intermediate wire feeding source that is disposed between the wire feeding source and the welding torch and is configured to temporarily accommodate the welding wire fed from the wire feeding source and to feed the accommodated welding wire to the welding torch; a pull-out feeding part that feeds the welding wire at the wire feeding source to the intermediate wire feeding source; and a push-out feeding part that feeds the welding wire accommodated in the intermediate wire feeding source to the welding torch.Type: GrantFiled: March 9, 2017Date of Patent: June 28, 2022Assignee: DAIHEN CorporationInventors: Masahiro Inoue, Yukiya Morita, Hisao Miyahara, Hirokazu Kawai, Songjie Hou, Hayato Baba, Hideo Shiozaki, Tetsuo Era, Tomoyuki Ueyama

Patent number: 7390039Abstract: A bumper absorber for protecting pedestrians is formed into a W-shaped cross-sectional configuration, as taken along a direction which is orthogonal to a longitudinal direction of the bumper absorber. The W-shaped cross sectional configuration has portions in which a front notch portion, an upper rear notch portion, and a lower rear notch portion overlap with one another in a vertical direction of a vehicle. Ribs are formed respectively at the upper rear notch portion and the lower rear notch portion, and a triangular notch is formed from a vehicle rear side at each of the rib. Further, the ribs 30 are formed at the upper rear notch portion and the lower rear notch portion so as to be separated from each other at predetermined intervals in a longitudinal direction of the bumper absorber, namely, in a transverse direction of the vehicle. With this structure, a rise in impact load acting on a pedestrian who is hit by a bumper can be controlled.Type: GrantFiled: April 23, 2007Date of Patent: June 24, 2008Assignees: Sekisui Kaseihin Kogyo Kabushiki Kaisha, Kabushiki Kaisha ChugaiInventors: Junji Adachi, Naruaki Abe, Fumihiko Sato, Taku Fukuyama, Kouji Mori, Yoshikatsu Miwa, Yukiya Morita
