Publication number: 20230313693Abstract: A rotor assembly component which is a component of a gas turbine engine is provided with a rotor assembly component body made from a metal, and a hard particle layer including a mass of hard particles and a matrix material, with the hard particles being made from a material harder than a material forming the rotor assembly component body. The matrix material is made solely from the material forming the rotor assembly component body. The hard particle layer is supported directly on a surface of the rotor assembly component body.Type: ApplicationFiled: May 18, 2023Publication date: October 5, 2023Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Yoshikatsu SATO, Ryo MORIHASHI, Toshiro TSUJI, Hiroshi TAKI, Kazushige FUJIMITSU

Patent number: 10549468Abstract: A spinning forming method includes a first forming step and a second forming step, in each of which a plate fixed to a main shaft is formed while being rotated. In the first forming step, a processing tool is brought into contact with a first main surface of the plate to form a first level-changing portion extending from the first main surface toward a second main surface. In the second forming step, the processing tool is brought into contact with the second main surface at an outer peripheral side of the first level-changing portion to form a second level-changing portion extending in an opposite direction to the first level-changing portion.Type: GrantFiled: August 30, 2013Date of Patent: February 4, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Hideyuki Ogishi, Hayato Iwasaki, Yoshihide Imamura, Yuto Sakane, Toshiro Tsuji, Hiroshi Kitano

Patent number: 10413999Abstract: First, an annular first layer including a plurality of beads and having a width that is not less than twice a width of the bead is formed by laser metal deposition on a peripheral surface of a base metal, the peripheral surface facing outward or inward in a radial direction. Next, a plurality of annular height raising layers each including a plurality of beads are stacked on the first layer by the laser metal deposition. According to this configuration, an axisymmetric body including a flange portion having a relatively wide width can be manufactured while making a heat affected zone in the base metal extremely small.Type: GrantFiled: June 3, 2015Date of Patent: September 17, 2019Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Toshiro Tsuji, Yoshiro Kabe, Yoshihide Imamura, Hayato Iwasaki, Hiroshi Kitano

Patent number: 10092941Abstract: A spinning forming apparatus shapes a plate while rotating the plate around a rotational axis. The spinning forming apparatus includes: a holding member to which the plate is attached and which rotates the plate around the rotational axis; a processing tool configured to contact a first main surface of the plate to process and shape the plate; and a heater configured to heat the plate. The heater is arranged at the opposite side of the processing tool across the plate. The heater locally heats a position of a second main surface of the plate opposite to the first main surface, the position being located on a circumference around the rotational axis, the circumference being defined by a position, with which the processing tool contacts, of the plate.Type: GrantFiled: July 17, 2013Date of Patent: October 9, 2018Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Hideyuki Ogishi, Hayato Iwasaki, Yoshihide Imamura, Yuto Sakane, Toshiro Tsuji, Hiroshi Kitano, Kazunori Hara

Publication number: 20170304885Abstract: A spinning forming method is a method of forming a formation target region of a plate into a tapered shape by using a processing tool while rotating the plate. The processing tool is moved from an inside edge of the formation target region to an outside edge of the formation target region while being pressed against the plate. The plate is rotated in a state where a position of the processing tool is fixed at the outside edge.Type: ApplicationFiled: October 13, 2015Publication date: October 26, 2017Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Kohei MIKAMI, Yoshihide IMAMURA, Toshiro TSUJI, Yoshiro KABE, Hayato IWASAKI, Hiroshi KITANO

Publication number: 20150328673Abstract: An object of the present invention is to reduce heat transferred from a plate through a receiving jig to a rotating shaft in a spinning forming device. A spinning forming device includes: a receiving jig supporting a central portion of a plate to be formed; a rotating shaft to which the receiving jig is attached; a heater configured to heat a transform target portion of the plate by induction heating; and a processing tool configured to press the transform target portion to transform the plate. The receiving jig is configured to suppress heat transfer from the plate to rotating shaft.Type: ApplicationFiled: November 27, 2013Publication date: November 19, 2015Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Yoshihide IMAMURA, Yuto SAKANE, Hayato IWASAKI, Toshiro TSUJI, Kohei MIKAMI, Hideyuki OGISHI

Patent number: 3931007Abstract: A method is provided for extracting metal impurities from waste water to which ferrous ions are added to provide at least two times the amount of ferrous ions on the mol basis to the amount of metal ions present, the resulting solution containing acid radicals, a base being added to the solution to raise the pH to form a suspension of metal hydroxides, following which an oxidizing gas is bubbled in solution to form crystals containing ferric ions and further containing the metal ions originally in solution, the precipitated crystals being thereafter separated to provide clean water.Type: GrantFiled: December 17, 1973Date of Patent: January 6, 1976Assignee: Nippon Electric Company LimitedInventors: Izuru Sugano, Toshiro Tsuji, Masaru Kanamori
