  • Publication number: 20230394186
    Abstract: 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.

  • Patent number: 8911269
    Abstract: A conductor connecting structure comprises a flat circuit body having an insulator and a conductor, and a conductive terminal metal fitting having a conductor connecting part including a first conductor holding part and a second conductor holding part. The first conductor holding part has a first plate-like part formed into a plate-like shape, and a projecting part which projects from a surface of the first plate-like part that is faced to the conductor. The second conductor holding part has a second plate-like part formed into a plate-like shape, and a through hole arranged so as to correspond to a position of the projecting part and penetrating the second plate-like part. When the conductor is sandwiched by the first conductor holding part and the second conductor holding part, the conductor is deformed so as to be pushed into the through hole.

  • Patent number: 8816204
    Abstract: A wire connecting method and a wiring harness that allows one to utilize a single terminal for multiple core wires having various diameters thereby reducing the number and different types of terminals. The wire connecting method allows the larger wire cores first to be ultrasonic pressed such that the diameter of the larger core wires are reduced to sizes that are small enough to utilize the single terminal used on smaller core wires.

  • Patent number: 8490854
    Abstract: 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.

  • Publication number: 20130025935
    Abstract: [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.

  • Patent number: 7978384
    Abstract: 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.
