Patent number: 10403418Abstract: Cost reduction in a multicore cable is realized by reduction in the frequency of damaging a coaxial cable upon removal of a covering layer. A multicore cable 10 includes multiple coaxial cables 11 arranged in parallel, and ground members 15, 16 conductively connected with the coaxial cables 11. Each coaxial cable includes an internal conductor 11a, an internal insulating layer 11b covering an outer peripheral surface of the internal conductor 11a, an external conductor 11c covering an outer peripheral surface of the internal insulating layer 11b, a covering layer 11d covering an outer peripheral surface of the external conductor 11c, a removed portion 11e formed in such a manner that part of the covering layer 11d in a circumferential direction is removed such that the external conductor 11c is exposed, and a conductive member 21 filling the removed portion 11e. The ground member 15 is conductively connected with the conductive member 21 filling the removed portion 11e.Type: GrantFiled: February 21, 2017Date of Patent: September 3, 2019Assignee: TATSUTA ELECTRIC WIRE & CABLE CO., LTD.Inventors: Yoshihiko Aoyagi, Yoshinori Kawakami, Kiyotaka Urashita

Patent number: 10206289Abstract: Soldering is performed with a high yield ratio even when extremely-thin wires are joined at an extremely-narrow pitch. Moreover, a bridge between conductive joint portions is reduced. A core wire 41 is placed on a preliminarily-soldered conductive joint portion 2. Then, the conductive joint portions 2 and the core wires 41 are covered with an optically-transparent sheet 30. Thus, the state in which the core wire 41 is placed on the conductive joint portion 2 is held. In this state, the optically-transparent sheet 30 is irradiated with light. A preliminary solder 3 is heated and melted to join the core wire 41 and the conductive joint portion 2 together.Type: GrantFiled: October 29, 2015Date of Patent: February 12, 2019Assignee: TATSUTA ELECTRIC WIRE & CABLE CO., LTD.Inventors: Yoshihiko Aoyagi, Yoshinori Kawakami, Yoshio Hirano, Kiyotaka Urashita, Ryota Fujikawa, Nobuhiro Fujio

Patent number: 5588103Abstract: A document editor for editing and displaying elements of a graphic with a logic structure which have an inclusive, side-by-side, or connective relationship mutually. The document editor comprises an editing unit for editing any element of said logic structure and reflecting the result of editing on other elements, an output unit for externally displaying the result of reflective editing, if necessary, and a control unit for designating display or non-display of the result of reflective editing for each element of said logic structure, and controlling the output unit in terms of display or non-display of the result of reflective editing according to the designation. By the constitution, during document editing and display, stepwise display of details can be controlled according to a logic structure, and any element can be edited in a selected display stage. Eventually, the constitution contributes to a reduction in the quantity of display information and a display time interval.Type: GrantFiled: July 14, 1994Date of Patent: December 24, 1996Assignee: Fujitsu LimitedInventor: Yoshihiko Aoyagi
