Publication number: 20020190428Abstract: A gas-permeable plug is adapted to be inserted in an insertion hole formed through a part of a casing in an inward-outward direction. The gas-permeable plug has a plug body and a permeable sheet including therein countless minute permeable pores. The plug body is injection molded from a material having rubber-like elasticity and the permeable sheet is integrally bonded to a sheet bonding portion by an anchor operation such that when the plug body is injection molded, at the sheet bonding portion, a part of a heat-melted liquid resin enters the minute permeable pores and/or the permeable gaps in irregular directions by the injection molding pressure and is solidified.Type: ApplicationFiled: June 7, 2002Publication date: December 19, 2002Inventors: Tatsuya Tamura, Kouichi Hara

Patent number: 6327137Abstract: An electric double layer capacitor with a control circuit component. When the electric double layer capacitor is provided in plural and these capacitors are serially connected for charging thereof through a source of DC power, the control circuit component balances charge Voltage of each electric double layer capacitor. The control circuit component is mounted to a control circuit board. The control circuit board has a diameter smaller than that of a sheath can of the electric double layer capacitor and is fixedly secured to a cover such that it does not project upwardly beyond an upper end of a pole projection, serving as a positive electrode, of the electric double layer capacitor.Type: GrantFiled: September 8, 2000Date of Patent: December 4, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Koichi Yamamoto, Kenji Matsumoto, Toshiyuki Matsuoka, Kentaro Shibuya

Patent number: 5959830Abstract: A stack type electric double layer capacitor includes a plurality of unit cells, each with a pair of polarizing electrodes facing each other across a porous separator, a pair of current collecting members, and a gasket surrounding the electrodes and current collecting members. The gasket has a heat radiation notch in the direction parallel to or perpendicular to the stacking direction. This prevents heat from accumulating in the capacitor at the time of rapid charge and discharge, and thereby enhances the reliability of the capacitor.Type: GrantFiled: July 30, 1997Date of Patent: September 28, 1999Assignee: NEC CorporationInventors: Masako Inagawa, Munekazu Aoki, Keitaro Katsu

The capacitor includes at least one basic cell. Each of the at least one basic cell has (a) an insulative, tubular gasket having a tubular inner space and opening ends, (b) a pair of polarizable electrodes made of a solid activated-carbon, (c) a sheet-like, porous, non electron-conductive separator sandwiched between the pair of electrodes; and (d) a pair of conductive, sheet-like collectors placed to close the opening ends of the gasket. The pair of collectors are electrically connected to a pair of external terminals. The pair of electrodes and the separator are placed in the inner space of the gasket. The gasket is made of a thermoplastic resin and is formed by injection molding. The separator and the pair of electrodes are unified with the gasket.Type: GrantFiled: March 28, 1997Date of Patent: January 12, 1999Assignee: NEC CorporationInventors: Munekazu Aoki, Keitaro Katsu
