Patent number: 8071919Abstract: In a heating cooker, an object to be heated is placed on a top plate and is heated by a heating unit located below the top plate. The top plate is translucent and a fluorescent display tube is located below the top plate. The top plate is configured to have spectral transmission characteristics in a visible light range such that the spectral transmission at a wavelength of approximately 500 nm corresponding to blue or green is substantially one third of a spectral transmission at a wavelength of approximately 700 nm corresponding to red such that the spectral transmission is gradually rendered larger as the wavelength is increased from approximately 500 nm to approximately 700 nm.Type: GrantFiled: November 9, 2006Date of Patent: December 6, 2011Assignees: Kabushiki Kaisha Toshiba, Toshiba HA Products Co., Ltd., Toshiba Consumer Marketing CorporationInventors: Kazunari Imamoto, Takeshi Esaki, Masao Kondo, Katsuharu Matsuo

Patent number: 7990681Abstract: An aluminum electrolytic capacitor having an excellent short-circuit resistance, high capacitance, long life, and low equivalent series resistance (ESR) is provided. For this purpose, the aluminum electrolytic capacitor includes a capacitor element having a positive electrode foil, a first separator, a negative electrode foil, and a second separator, which are sequentially laminated one on another and wound together. After the capacitor element is impregnated with a driving electrolyte solution and housed in a metallic case, an open end of the metallic case is sealed with a sealing material. A ratio of B/A, i.e. a ratio of total thickness B of the first and second separators after winding with respect to total thickness A of the first and second separators before winding, is set in the range from 0.5 to 0.8.Type: GrantFiled: May 9, 2007Date of Patent: August 2, 2011Assignee: Panasonic CorporationInventors: Hisao Nagara, Kazunari Imamoto, Shigetaka Furusawa, Hiroyuki Matsuura
