Publication number: 20100104907Abstract: In an electronic device, state detection elements are arranged at various locations of a fuel cell system supplies an electric power to a phone unit, the state detection elements detect states of the fuel cell system at the locations. A cell state detection unit detects an operating state of the fuel cell from an output signal of each of the state detection elements. A determination unit determines an operating mode to prompt action to be taken for the operating state of the fuel cell detected by the cell state detection unit. A content of the operating mode is displayed with an image of a character or a fictitious creature based on a determination by the determination unit.Type: ApplicationFiled: December 31, 2009Publication date: April 29, 2010Inventors: Risa AOKI, Akira Yajima, Asako Satoh, Jun Momma, Yumiko Takizawa, Yuuichi Sato, Genta Oomichi, Hirofumi Kan, Nobuyasu Negishi, Mitsuru Furuichi, Yuichi Yoshida, Kiyoto Yoda, Hideo Oota

Patent number: 7566515Abstract: A non-aqueous electrolyte secondary cell containing an electricity-generating element with at least a cathode, a separator and an anode and a non-aqueous electrolyte inside a cathode case, electrode units each consisting of the cathode and the anode opposite to each another via the separator laminated to form an electrode group, or an electrode unit in a sheet form consisting of the cathode and the anode opposite to each another via the separator wound to form an electrode group, or a sheet-shape cathode wrapped with the separator except for a part contacting at inner face of cathode case and a sheet-shaped anode set on the sheet-shaped cathode in a right angled position each other and bent alternately to form an electrode group, and the total sum of the areas of the opposing cathode and anode in the electrode group larger than the area of the opening of an insulating gasket in a sealed portion in the cathode case or than the area of an opening in a sealed plate in a sealed portion in the cathode case.Type: GrantFiled: July 8, 2005Date of Patent: July 28, 2009Assignee: Toshiba Battery Co., Ltd.Inventors: Masami Suzuki, Muneto Hayami, Kazuo Udagawa, Kazuo Iizuka, Naomi Ishihara, Satoshi Hirahara, Hirotaka Sakai, Kiyoto Yoda, Masataka Shikota
