Patent number: 7551947Abstract: A communication partner to be kept secret is registered as a security member. When an incoming call has arrived, an incoming call notification operation is normally performed if the transmission source is not a security member. If the transmission source is a security member, no incoming call notification operation is performed. Instead, the display color of a clock always displayed in, e.g., the standby image is changed to a display color which the user himself or herself sets and he or she alone knows.Type: GrantFiled: March 24, 2005Date of Patent: June 23, 2009Assignee: Kabushiki Kaisha ToshibaInventor: Katsuhiko Yoshida

Patent number: 7070639Abstract: A cyclonic vacuum cleaner with simple structure, low airflow leakage, excellent maintainability, and less possibility of littering a floor in the case of dumping dusts or care of the cleaner. A cyclonic portion 14 of an approximately cylindrical shape, having a bottom, an introducing portion 15 for introducing dust-laden airflow to the cyclonic portion 14, and a reinforcing rib 35 provided on a lowermost end of the dust-collecting portion 11 for allowing it to stand on end, are formed into a one-piece structure. Thus, the structure from the introducing portion 15 to the cyclonic portion 14 can be simplified and the possibility of airflow leakage can be reduced. Also, maintenance of the cyclonic portion 14 and the introducing portion 15 can be easily performed through the detachment of the dust-collecting portion 11 together with the introducing portion 15.Type: GrantFiled: April 1, 2003Date of Patent: July 4, 2006Assignee: Twinbird CorporationInventors: Mineyuki Inoue, Katsuhiko Yoshida, Takeshi Yamada
