Patent number: 10077826Abstract: Respective outer peripheral surfaces (33, 35) of opening-side end portions (30, 31) of a front cover (12) and a pump shell (7), which have been shaped by pressing, are formed by slimming such that the outside diameters of the slimmed outer peripheral surfaces are equal to each other. With the opening-side end portions abutting against each other, a high-energy beam such as a laser beam (R) is radiated toward the abutment surfaces (30, 31) from the radially outer side to weld the abutment surfaces to each other. Consequently, it is possible to perform welding accurately through easy processing in order to easily manufacture a fluid coupling with high precision that facilitates post-processing.Type: GrantFiled: November 26, 2014Date of Patent: September 18, 2018Assignees: AISIN AW CO.

Patent number: 9296016Abstract: A double-structure coated object includes an outer plate portion configured to produce a target color by stacking a coating film of a first paint and a coating film of a second paint, and an inner plate portion on which a coating film of the second paint is formed. When the coating film is formed on the inner plate portion, and then the first paint and the second paint are sequentially applied to the outer plate portion, paint dust on the inner plate portion is prevented from causing viewers to feel something different about color. To achieve this, the ratio (1BC)/(1BC+2BC) of the spectral reflectance (1BC) of the color of the coating film made of the first paint to the spectral reflectance (1BC+2BC) of the target color is configured to fall within a predetermined range.Type: GrantFiled: February 23, 2011Date of Patent: March 29, 2016Assignee: MAZDA MOTOR CORPORATIONInventors: Sakura Nakano, Takakazu Yamane, Hiroshi Kubota, Takako Ishibashi

HEAT-INSULATING STRUCTURE OF MEMBER FACING ENGINE COMBUSTION CHAMBER, AND PROCESS FOR PRODUCING SAME
Publication number: 20150204233Abstract: A heat-insulating layer exhibiting high resistance to cracks, peeling, deformation, and gasoline and high heat insulation is obtained on the wall surface of an engine member (19). First, a heat insulator layer including a silicone-based resin and hollow particles containing a Si-based oxide is formed on a wall surface of the engine member (19). Then, Si-based oxide is produced through oxidation of a silicone-based resin in at least part of the surface of the heat insulator layer by heating the surface of the heat insulator layer. Thereafter, a catalytic metal is added to the silicone-based resin in the surface of the heat insulator layer and/or Si-based oxide derived from the hollow particles. Using the catalytic metal as nuclei, electroless plating is performed. In this manner, a heat-insulating layer (21) in which the surface of the heat-insulating film (27) is covered with a plating film (29) is obtained.Type: ApplicationFiled: July 24, 2013Publication date: July 23, 2015Applicant: MAZDA MOTOR CORPORATIONInventors: Satoshi Nanba, Shinji Kadoshima, Daiji Katsura, Nobuo Sakate, Takakazu Yamane, Akihide Takami -
