Patent number: 6737187Abstract: A closed battery which is capable of rapidly releasing the internal pressure there while simultaneously disconnecting the current to prevent the internal temperature of the battery from rising and causing the battery to explode. Thus, when the internal pressure of the closed battery is elevated due to a short circuit, overcharge, reverse charge, or the like, internal gas in the battery can be safely discharged and the battery prevented from bursting.Type: GrantFiled: August 1, 2001Date of Patent: May 18, 2004Assignees: Toyo Kohan Co., Ltd., Fukuda Metal Foil & Powder Co., Ltd.Inventors: Akiyoshi Takada, Kinji Saijo, Kazuo Yoshida, Nobuyuki Yoshimoto, Yoshihiko Isobe

Patent number: 6440599Abstract: The object of the present invention is to provide a closed battery capable of rapidly releasing the internal pressure thereof and at the same time disconnecting the current to effectively prevent a rise in temperature and explosion so that it may assure the safety and reliability of the battery, when, the internal pressure is elevated due to short circuit, overcharge, reverse charge, or the like in such a completely closed battery. A closed battery of the present invention is provided with a closing member serving as a valve chip, which is composed of a metal substrate 1 in which a valve element 5 is provided and defined by a break line 3, and a metal foil 2 adhered to the inner surface of the metal substrate 1.Type: GrantFiled: January 6, 2000Date of Patent: August 27, 2002Assignees: Toyo Kohan Co., Ltd., Fukuda Metal Foil & Powder Co., Ltd.Inventors: Akiyoshi Takada, Kinji Saijo, Kazuo Yoshida, Nobuyuki Yoshimoto, Yoshihiko Isobe

Patent number: 6423440Abstract: The object of the present invention is to provide a closed battery capable of rapidly releasing the internal pressure thereof and at the same time disconnecting the current to effectively prevent itself from temperature rising and exploding so that in such a completely closed battery it may assure the safety and reliability thereof, when the internal pressure is elevated due to short circuit, overcharge, reverse charge, or the like. A valve element 5 is provided with a slit 3 between the circumference thereof and a metal substrate 1. When the internal pressure of a battery is elevated, the valve element 5 is smoothly raised up together with a metal foil 2 from a bending fulcrum portion 4 to thereby cut a lead wire 6 or permit a braze portion 8 to detach from the lead wire 6, thus disconnecting the current reliably.Type: GrantFiled: November 9, 1999Date of Patent: July 23, 2002Assignees: Toyo Kohan Co., Ltd., Fukuda Metal Foil & Powder Co., Ltd.Inventors: Akiyoshi Takada, Kinji Saijo, Kazuo Yoshida, Nobuyuki Yoshimoto, Yoshihiko Isobe

Patent number: 6303246Abstract: The object of the present invention is to provide a closed battery capable of rapidly releasing the internal pressure thereof and at the same time disconnecting the current to effectively prevent itself from temperature rising and explosion so that it may assure the safety and reliability thereof, when the internal pressure is elevated due to short circuit, overcharge, reverse charge, or the like in such a completely closed battery. The formation of a valve element 5 whose center is eccentric to the center of a metal substrate 1 produces a slit 3 having a large width portion around the circumference of a valve element 5. When the internal pressure of a battery is elevated, the valve element 5 is smoothly raised up together with a metal foil 2 from the bending fulcrum portion 4 to thereby cut a lead wire 6 or permit a braze portion 8 to detach from the lead wire 6, thus reliably disconnecting the current.Type: GrantFiled: January 14, 2000Date of Patent: October 16, 2001Assignee: Toyo Kohan Co., Ltd.Inventors: Akiyoshi Takada, Kinji Saijo, Kazuo Yoshida, Nobuyuki Yoshimoto, Yoshihiko Isobe

Patent number: 6150037Abstract: Clad material comprises a metal substrate which is provided with a multiplicity of perforated openings therein and a metal foil which is laminated on the metal substrate to close the perforated openings. To produce such a clad material, at least one surface of the metal substrate and corresponding one surface of the metal foil are respectively subjected to a dry etching and the metal substrate and the metal foil are laminated in such a manner that the etched surfaces face each other. Alternately, only one surface of the metal substrate is subjected to a dry etching and the metal substrate and the metal foil are laminated in such a manner that the etched surface of the metal substrate defines a laminating surface. It may be possible to provide a nickel plating on the metal substrate or the metal foil. The clad material can be effectively used for producing safety valve chips which rupture accurately at low pressures which fall in a stable pressure range on a mass production basis.Type: GrantFiled: August 12, 1998Date of Patent: November 21, 2000Assignee: Toyo Kohan Co., LTDInventors: Kinji Saijo, Kazuo Yoshida, Nobuyuki Yoshimoto, Yoshihiko Isobe
