Publication number: 20090228735Abstract: In an information processing apparatus and elapsed time measuring method of the present invention, a microcomputer for power supply control measures an elapsed time when the product is in an operating condition, a time when the product is powered off is read from an RTC in a system LSI and written to a storage unit in a BIOS, a time when the product is next powered on is read from the RTC, and a difference between the two times is calculated in order to obtain an elapsed time for when the product is in a non-operating condition. An elapsed time of the product is calculated by adding together two types of elapsed times in the BIOS. This structure enables providing an information processing apparatus and elapsed time measuring method that can accurately measure the elapsed time of the product without being influenced by a user operation.Type: ApplicationFiled: March 3, 2009Publication date: September 10, 2009Applicant: PANASONIC CORPORATIONInventors: Seiji IKEDA, Yoichi AYABE

Patent number: 5937648Abstract: The gas compression/expansion apparatus comprises: a working section for compressing/expanding therein a working gas by pistons each connected with a rod; a drive section including sliders each connected at one end thereof with the rod and connected at one end thereof with a guide for guiding the slider, and a drive mechanism for reciprocating the sliders; and a separator for fluid dynamically separating the working section from the drive section, the separator permitting said rod to pass through said separator. The separator further includes an oil seal arrangement. Formed inside the separator is an intermediate chamber which allows the rod to pass there through. The inner radius of the intermediate chamber is greater than the radius of the rod plus the oil deposited on the rod. The guide includes a guide space formed such that the distance between the slider at its upper dead point and the wall of the separator facing the slider is larger than the thickness of the oil on the slider.Type: GrantFiled: February 26, 1997Date of Patent: August 17, 1999Assignee: Sanyo Electric Co., Ltd.Inventors: Tatsuya Hirose, Kazuo Ikegami, Seiji Ikeda

Patent number: 5513546Abstract: A device for fastening and loosening threaded members which has a socket mechanism at its forward end for engaging the threaded member and in which the torque of a motor rotatable in one direction is transmitted to the socket mechanism via a rotation transmission route including a planetary gear mechanism, forward-reverse rotation changing assembly and bevel gear mechanism. The bevel gear mechanism comprises a drive bevel gear coupled to the motor, and a pair of driven bevel gears opposed to each other in orthogonal relation to the axis of the drive gear and aligned with the axis of the planetary gear mechanism, the driven bevel gears being in mesh with the drive gear. The rotation changing assembly comprises an output shaft rotatably extending through the driven gears, and engaging means for selectively engaging one of the driven gears with the output shaft for the engaged gear to rotate with the shaft or disengaging the gear from the shaft. The output shaft is coupled to the planetary gear mechanism.Type: GrantFiled: September 15, 1994Date of Patent: May 7, 1996Assignee: Maeda Metal Industries, Ltd.Inventors: Seiji Ikeda, Shinji Fukuhara

Patent number: 5407041Abstract: A lock-up device is used for a torque converter comprising a front cover connected to an input-side rotation member, an impeller fixed to the front cover, and a turbine provided opposite to the impeller and connected to an output-side member. This lock-up device comprises a plate member and a piston. The above described plate member is connected to the output-side member and located between the turbine and the inner wall of the front cover, and can be brought into contact with the inner wall of the front cover. The above described piston which is connected to the front cover so as not to be relatively rotatable is for pressing the plate member against the inner wall of the front cover.Type: GrantFiled: September 7, 1993Date of Patent: April 18, 1995Assignee: Kabushiki Kaisha Daikin SeisakushoInventors: Takao Fukunaga, Seiji Ikeda
