  • Patent number: 7406763
    Abstract: A method of producing a multiconductor cable is provided herein. A plurality of wires are arranged in a flat array with a specific pitch at both ends of them having an intermediate portion that are bundled together and a transforming portion. The plurality of wires have lengths different from one another, where the lengths vary successively from the minimum length, Ls, to the maximum length, Lm. At both end portions, the transforming portion of the wires are arranged using an arranging tool and attached so that the wires are held in grooves. The wires are moved from the arranging tool and a terminal structure is formed for electrical connection at both ends of the multiconductor cable.

  • Publication number: 20060266541
    Abstract: A multiconductor cable is reduced in the possibility of break even for use at a place where the cable undergoes twisting, and a method can produce the multiconductor cable easily at a low cost. The multiconductor cable in corporates a plurality of wires that are arranged in a flat array with a specific pitch at both ends of them, that have an intermediate portion at which they are bundled together; and that have lengths different from one another, the lengths varying successively from the minimum length, Ls, to the maximum length, Lm. The multiconductor cable satisfies the formulae “D/E>?,” and “(Lm?Ls)>{(D2+E2)1/2?E},” where D is the width of the cable at both ends, E is the distance between the ends of the cable, Lm is the maximum length, and Ls is the minimum length.

  • Patent number: 4141292
    Abstract: A mimeograph device which comprises a rectangular framework having a center window, a closure plate slidably received in the framework and having a knob, a perforated plate convexed downwardly and attached to the undersurface of the framework to define an ink holding chamber in cooperation with the closure plate, an air-liquid permeable sponge sheet convexed downwardly and applied to the undersurface of the perforated plate and a screen convexed downwardly and applied to the undersurface of the sponge sheet for releasably receiving a stencil paper thereon.
