Publication number: 20190301528Abstract: A problem is to provide a sliding member capable of easily improving friction characteristics, and a production method therefor. A solution is a sliding member 10, wherein a sliding portion 11 is formed of a metallic material, and the sliding member 10 has, on a surface of the sliding portion 11, a Cr-containing modified layer 12 formed by blasting a shot media containing Cr as a composition. The sliding member 10 slides under an environment of a lubricant containing Mo as an additive, in which active Cr exposed on the surface by sliding accelerates decomposition reaction of the additive contained in the lubricant to form a molybdenum disulfide-containing film having low friction on the surface of the sliding portion 11.Type: ApplicationFiled: March 27, 2019Publication date: October 3, 2019Applicants: TOYOTA MOTOR EAST JAPAN, INC., TOYOTA JIDOSHA KABUSHIKI KAISHA, Macoho co., Ltd.Inventors: Ryo KOIKE, Kazuyoshi MANABE, Sachito MATSUBARA, Masayoshi OGATA

Publication number: 20160184968Abstract: The purpose of the present invention is to provide a nozzle body for an innovative wet-blast processing apparatus that demonstrates unprecedented effects. The present invention is a nozzle body for a wet-blast processing apparatus in which a slurry (4) formed by mixing an abrasive (3) in a liquid (2) can be jetted together with pressurized air. The nozzle body removes burrs attached to a terminal (20b) of a semiconductor package (20) formed by providing a wiring substrate with an electronic component such as a semiconductor integrated circuit chip and covering the semiconductor package (20) with a synthetic resin. The nozzle body has a slurry-jetting opening (5) for jetting the slurry (4) to the tip of a cylindrical main body (6). The slurry-jetting opening (5) is formed having a polygonal shape in cross-section.Type: ApplicationFiled: November 19, 2015Publication date: June 30, 2016Applicant: MACOHO CO. LTD.Inventors: Sachito MATSUBARA, Masanori TSUCHIDA

Patent number: 6269669Abstract: Improvement in a method of surface-treating a back plate for friction material by blasting slurry containing particles made of plastic material through high pressure air to obtain desired surface roughness constantly for a long period of time. In the present method, no alumina grinding particle but particles made of stainless steel or titanium are fed into slurry, and the slurry is blasted through high pressure air to surface-treat the back plates. Stainless steel or the like strike works to make the surface thereof rough, which does not cause the stainless steel particles or titanium particles to be broken, unlike the grinding particles, so that the amount of sludge generated is reduced, resulting in longer life of the slurry.Type: GrantFiled: March 25, 1999Date of Patent: August 7, 2001Assignees: Nisshinbo Industries, Inc., Macoho Co., Ltd.Inventors: Tohru Matsubara, Kazuhiro Seki
