Patent number: 6934151Abstract: As a user depresses an eject button from the standard position to its sunken position and an instruction is transmitted to an installed notebook PC to request the disconnection of a driver for a device being operated in a docking station. When a notification is received from the PC indicating that the disconnection has been completed, for example and not to limit the a solenoid type electromagnetic apparatus switches a plunger to its non-projected position. The eject button is then placed into its projected position owing to the urging force of a spring. When the user depresses the eject button placed in its projected position, a motion direction converting lever is pivoted to activate an ejecting member and a locking hook. Consequently, the PC is ejected.Type: GrantFiled: March 3, 2004Date of Patent: August 23, 2005Assignee: Lenovo PTE LTDInventors: Masayoshi Nakano, Hideyuki Usui

Patent number: 6800840Abstract: A portable information processor includes a computer main body and a digitizer connected by a flexible hinge defined in a cover. The hinge allows the computer main body and the digitizer to assume different superposed states by means of a flexible separable portion of the cover. In the superposed state of the computer main body and the digitizer, arbitrariness in folding back the separable portion causes runout between the computer main body and the digitizer. In spite of this runout, the superposed state can be accurately detected by means of an optical sensor, including an infrared radiator and an infrared-ray detector, disposed in the computer main body. A flexible reflection member is fixed to a predetermined surface of the separable portion of the leather cover, while assuring a predetermined area. If the computer main body and the digitizer assume a superposed state, light emitted from the infrared radiator is reflected by the flexible reflection member and is incident on the infrared-ray detector.Type: GrantFiled: September 11, 2001Date of Patent: October 5, 2004Assignee: International Business Machines CorporationInventors: Masayoshi Nakano, Tetsuji Nakamura, Takashi Yanagisawa, Fusanobu Nakamura

Patent number: 6574102Abstract: To provide a docking station for a portable computer, which increases its heat radiation when the docking station is docked with the portable computer. A docking station is equipped with a fan unit at a back portion of a power supply unit within a station body, and a front surface of a connection portion with which a notebook PC is docked is provided with an air suction opening. Thereby, once the fan unit is driven, high temperature air is exhausted from a station body and the connection portion, then outside air is introduced from the suction opening to stimulate the cooling of the connection portion, and the heat which is transferred from a back side portion of the notebook PC to the connection portion is also dissipated there to stimulate the cooling of the notebook PC side.Type: GrantFiled: March 30, 2001Date of Patent: June 3, 2003Assignee: International Business Machines CorporationInventors: Hideyuki Usui, Akihiko Inoue, Takashi Yanagisawa, Masayoshi Nakano
