Publication number: 20110214134Abstract: A control unit makes the slot control mechanism execute an failure recovery operation to repeat the insertion operation and the ejection operation alternately for a predetermined amount at a first point of time when the below fact is found, if it is found that there is an error in insertion operation or ejection operation of a slot control mechanism. Afterwards, the control unit makes the slot control mechanism execute an restoration operation for a predetermined amount after a second point of time when the below fact is found, if it is found that the slot control mechanism has returned to normal, thereby making the slot control mechanism return to the state at the first point of time. Then, the control unit makes the slot control mechanism execute the insertion operation or the ejection operation again. With this arrangement, it is possible to ensure reliable insertion operation or ejection operation.Type: ApplicationFiled: February 25, 2011Publication date: September 1, 2011Inventor: Shinichi NAKATA

Patent number: 7321413Abstract: A liquid crystal display device which includes first and second organic interlaminar insulating films between pixel electrode and wire. The first interlaminar insulating film directly covers source electrode, source wire, drain electrode and back channel. Underlying one of the organic interlaminar insulating films directly contacts a channel part of a TFT. This provides an active matrix type liquid crystal display device with high transmittance and capable of bright displaying, which includes an active matrix wiring substrate having a structure of overlapping wires with a pixel electrode. The device can be prepared at low cost only through 5 photolithographic steps, i.e., without increasing the photolithographic steps as compared with those of the prior liquid crystal display device having high aperture ratio.Type: GrantFiled: August 8, 2002Date of Patent: January 22, 2008Assignee: NEC LCD Technologies, Ltd.Inventor: Shinichi Nakata

Publication number: 20070217768Abstract: When an image is formed on an optical disc, a pickup is moved by a pitch S in the radial direction of the optical disc together with a slider supporting the pickup. An objective lens within the pickup is shifted by a predetermined shift amount L by an actuator to emit a laser beam. The temperature in the vicinity of the pickup is detected by a temperature sensor. If the detected temperature has increased as much as, or more than, a threshold ?Tth relative to the temperature prior to the beginning of the formation of an image, a movement setting unit sets the slider movement pitch S and the objective lens shift amount L to small values so as to reduce the maximum drive current applied to the actuator.Type: ApplicationFiled: October 4, 2006Publication date: September 20, 2007Applicant: Hitachi-LG Data Storage, Inc.Inventor: Shinichi Nakata
