Patent number: 11986892Abstract: A machining tool is rotated around an axis and includes a machining blade portion having a first machining blade in the distal end direction with respect to a rake face and a second machining blade located in the radially outward direction with respect to the rake face, and a protrusion formed on the rake face and having a tip for cutting chips coming from the first machining blade. The protrusion includes an inner forming portion that is located in the radially inward direction from the reference line and an outer forming portion that is located in the radially outward direction from the reference line, and the width of the inner forming portion is wider than the width of the outer forming portion.Type: GrantFiled: February 28, 2022Date of Patent: May 21, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Junya Onose, Ryuji Daikyoku, Akihiro Osawa, Yusaku Kotaki, Tomoya Kuroda, Takayuki Konno, Mayumi Saruyama, Kyoko Tabata, Kazuya Sakaibara

Patent number: 9181897Abstract: A sliding member for which adhesiveness between the surface of a base member and metal coating is enhanced. An undercoat layer having a resin material at the surface thereof is provided, and a solid lubricating portion is formed on the undercoat layer so as to provide a sliding face from at least one kind of material of silver, silver alloy, copper and copper alloy. An intermixture layer in which both the undercoat layer and the solid lubricating portion are intermixed with each other is interposed between the undercoat layer and the solid lubricating portion.Type: GrantFiled: February 29, 2012Date of Patent: November 10, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Ryotaro Takada, Yoshitaka Tsujii, Takahisa Tashiro, Mayumi Saruyama, Yuki Furukawa

Patent number: 9175401Abstract: There are provided a sliding member that is enhanced in adhesiveness between the surface of a base member formed of aluminum or aluminum alloy and silver coating with a simple construction, and a method of manufacturing the sliding member. In a piston 1 having a sliding face 22 which slides in a cylinder bore 3, a silver coating layer 21 constituting the sliding face 22 is provided on the outer peripheral surface 11 of a main body 10 formed of aluminum alloy, and the silver coating layer 21 is formed by coating slurry having silver particles 23 dispersed in terpineol on the outer peripheral surface 11 of the main body 10 and heating the coated slurry and the main body 10 to remove terpineol in the slurry and fuse the silver particles 23 with one another.Type: GrantFiled: July 26, 2011Date of Patent: November 3, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Ryotaro Takada, Yoshitaka Tsujii, Mayumi Saruyama

Patent number: 8919319Abstract: Provided is an aluminum alloy piston for an internal combustion engine. In the internal combustion engine, the piston moves back and forth in a sleeve made of grey cast iron or an aluminum alloy. Further, the piston, which is made from silver, silver alloy, copper, or copper alloy, is provided with a film that covers the scoring that is formed on the piston skirt and there are undulations in the surface of the film, formed from protrusions and depressions. There is a difference of 8-15 ?m between the lowest point of the depressions and the highest point of the protrusions. The pitch of adjacent protrusions corresponds to the pitch of projections in the scoring. In addition, the arithmetic average roughness (Ra) of the protrusion peaks does not exceed 60 nm.Type: GrantFiled: March 16, 2011Date of Patent: December 30, 2014Assignee: Honda Motor Co., Ltd.Inventors: Ryotaro Takada, Mayumi Saruyama, Yositaka Tsujii
