Publication number: 20020061447Abstract: An electrode for secondary battery made of carbon material is provided, which is light in weight while excellent in charge-discharge properties and in durability in repetitive use. A material for electrode is obtained by intermixing a synthetic resin with vapor-phase growth carbon fibers to make the vapor-phase growth carbon fibers uniformly dispersed in the synthetic resin to obtain a mixture, molding the mixture into a predetermined shape to obtain a molded product, and heating the molded product at high temperature to convert it into a carbon-carbon composite material. The electrode for battery is made of thus obtained carbon-carbon composite material.Type: ApplicationFiled: January 24, 2002Publication date: May 23, 2002Applicant: YAZAKI CORPORATIONInventors: Toshiaki Kanno, Makoto Katsumata, Hidenori Yamanashi, Hitoshi Ushijima

Patent number: 5468918Abstract: A conductor member for an electric circuit includes a conductive plastic mold in which carbon fibers or graphite fibers are dispersedly contained, and a metallic layer at least partially plated on the surface of said conductive plastic mold. The conductor member is provided on the surface of an insulating substrate to provide an electric circuit body. Thus, the conductor member for an electric circuit and the electric circuit body can be easily formed in a three-dimensional circuit because of its simple fabrication and excellent processing. Further, the film of metal plating can be made at a high speed and is hard to break because of the intimate contact of the plated metal.Type: GrantFiled: December 16, 1993Date of Patent: November 21, 1995Assignee: Yazaki CorporationInventors: Toshiaki Kanno, Makoto Katsumata, Hidenori Yamanashi, Hitoshi Ushijima

Patent number: 5458967Abstract: A composite sheet for electromagnetic wave shield is light and excellent in laying operability and in magnetic field shielding property. The composite sheet for electromagnetic wave shield comprises a metal foil and a conductive hot melt resin layer laminated on each other. It is specifically desired that the conductive hot melt resin layer is made of a material in which vapor phase growth carbon fibers of diameters of not more than 1.0 .mu.m and lengths of not more than 50 .mu.m are dispersed in a hot melt resin. The conductive hot melt resin layer may be preferably provided at least on a part of one side of the metal foil.Type: GrantFiled: December 13, 1993Date of Patent: October 17, 1995Assignee: Yazaki CorporationInventors: Toshiaki Kanno, Makoto Katsumata, Hidenori Yamanashi, Hitoshi Ushijima

Patent number: 5371324Abstract: A ribbon cable which is light weight, noncorrosive and exhibits excellent electrical conductivity properties. The cable includes a plurality of conductors, each composed of exfoliated graphite, which are arranged to extend parallel to each other and are sheathed with an electrical insulative material molded of a synthetic resin. In another embodiment, a conductor composed of exfoliated graphite and metallic conductors, each having an elongated rectangular cross-sectional shape, are arranged to extend parallel to each other. The conductors are sandwiched between opposing sheets of synthetic resin which are adhered to each other.Type: GrantFiled: November 24, 1992Date of Patent: December 6, 1994Assignee: Yazaki CorporationInventors: Toshiaki Kanno, Hidenori Yamanashi, Tsuneyuki Horiike

Patent number: 5342997Abstract: The insulating members, almost circular or oval in cross section with an outer diameter virtually equal to the thickness of the rectangular conductor, are arranged in such a manner as to be alternated with the rectangular conductors and are held between the two insulating tapes from both the upper and lower sides, with the adhesive layer filling the space between the two facing tapes. The insulating tapes with adhesive layers on the opposing inner sides are pressed against the conductors and the insulating members by the press-forming rollers to form a tape wire.Type: GrantFiled: January 6, 1993Date of Patent: August 30, 1994Assignee: Yazaki CorporationInventors: Toshiaki Kanno, Akira Ikegaya, Tsuneyuki Horiike

Patent number: 4938705Abstract: A high-voltage wiring connection structure having first and second insulating members fitted with one another and protecting an electrical connection portion disposed within at least one of the first and second insulating members. A layer of a soft elastic silicone resin is provided on a surface of at least the two insulating members in contact with a mating surface of the other of the insulating members. An improved sealing effect, with reduced arcing and improved reliability, is thereby attained.Type: GrantFiled: May 13, 1988Date of Patent: July 3, 1990Assignee: Yazaki CorporationInventors: Toshiaki Kanno, Seiichi Wakabayashi

Patent number: 4923637Abstract: To obtain stable and high conductivity carbon fiber, hydrocarbon is thermodecomposed in vapor phase into carbon fiber with such a crystal structure that carbon hexagonal net planes thereof are arranged substantially in parallel to fiber axis and in annular ring growth fashion around the fiber axis, and then the carbon fiber is pulverized into 10 .mu.m or less long carbon fiber. Since the carbon fiber is pulverized into relatively short length, when mixed with resin or rubber material without damaging the carbon crystal structure, it is possible to obtain stable and high conductivity resin or rubber material. Further, it is also possible to effectively infiltrate reactive substance to between the carbon hexagonal net planes to form further higher conductivity carbon intercalation compound.Type: GrantFiled: June 23, 1988Date of Patent: May 8, 1990Assignee: Yazaki CorporationInventors: Kiyoshi Yagi, Toshiaki Kanno, Toshio Inada
