Publication number: 20230394186Abstract: A design support system (20) includes a controlling unit connected to an input unit. The controlling unit (21) obtains, from the input unit, information representing a flow channel network that simulates a flow channel shape. The controlling unit (21) then uses a flow channel width and a flow channel depth of the flow channel network, thereby generating design data of a three-dimensional flow channel that is obtained by three-dimensionalizing the flow channel network.Type: ApplicationFiled: July 21, 2021Publication date: December 7, 2023Inventors: Takayuki TSUKAMOTO, Tsutomu TAKAYAMA

Patent number: 8490854Abstract: A wire end processing method includes tree steps. In a core wire portion exposing step, a sheath of a wire is stripped so as to expose a core wire portion composed of a plurality of element wires. In a core wire portion unifying step, ultrasonic vibration is applied to the exposed core wire portion while applying a pressure thereto, thereby causing the plurality of the element wires to rub against one another so as to unify the core wire portion. In a terminal connecting step, the unified core wire portion is press-contacted or press-fitted to the terminal.Type: GrantFiled: January 18, 2011Date of Patent: July 23, 2013Assignee: Yazaki CorporationInventor: Tsutomu Takayama

Publication number: 20130025935Abstract: [Technical Problem]An object of the present invention is to provide a wire connecting method and a wiring harness allowed to reduce the number of types of terminals for reducing cost by increasing the number of core wire sizes able to be crimped or press-connected with respect to one terminal. [Solution to Problem]Regarding covered wires 13, 14 of which core wire diameter is larger than the core wire diameter allowed to be crimped with a wire barrel 18, an ultrasonic processing in which while pressure is applied to a core wire 16, ultrasonic energy is applied to the core wire 16 is performed. Thereby, the core wire diameter is reduced to be allowed to be crimped to the wire barrel 18, and the core wire 16 of the covered wire 13, 14 is crimped or press-connected between a pair of crimping pieces 18B of the terminal 15.Type: ApplicationFiled: April 8, 2011Publication date: January 31, 2013Applicant: YAZAKI CORPORATIONInventors: Tsutomu Takayama, Hiroshi Kobayashi, Saori Muramatsu, Shinya Kai, Takahito Nakajima

Patent number: 7978384Abstract: A construction is achieved at low cost which reduces the loss of gradation in a dark portion of an image that has been subjected to gamma correction in accordance with characteristics of a display. In an image reading apparatus, to make it possible to more finely reproduce the gradation in the dark portion, the number of gradations expressed by an signal obtained by a CCD is reduced by performing non-linear gamma correction using a gamma coefficient below one, and the resulting signal is transferred to a computer serving as a host computer. In the computer, the transferred signal is subjected to gamma correction using a gamma coefficient that is an inverse of the gamma coefficient used in the image reading apparatus, thereby canceling out the influence of the gamma correction performed in the image reading apparatus.Type: GrantFiled: July 14, 2005Date of Patent: July 12, 2011Assignee: Canon Kabushiki KaishaInventors: Kengo Kinumura, Tsutomu Takayama
