Publication number: 20050280403Abstract: In a programmable power supply used in a semiconductor test apparatus, high-speed switching of a large current in a current rage or an output relay is enabled. In a MOSFET drive circuit 22 of a switch portion 20 provided in a programmable power supply 10 of a semiconductor test apparatus 1, a capacitor portion 22-12 is charged with electric charges by a current from a light receiving portion 22-12 of a light insulating element 22-1. When an SWA is turned on (SWB is turned off) by changeover of the analog switch portion 22-3, a gate of each MOSFET in the MOSFET portion 21 is charged with the electric charges stored in the capacitor portion 22-12, and enters an ON state. On the other hand, when the SWB of the analog switch portion 22-3 is turned on (SWA is turned off), the gate of the MOSFET is discharged.Type: ApplicationFiled: June 22, 2004Publication date: December 22, 2005Inventor: Nobuhiro Sato

Publication number: 20040027961Abstract: When a sliding plate slides forward by the rotating force of a motor, the lower part of a movable member is driven and the movable member set in a vertical state moves forward with the vertical state maintained, and the movable member is then rotated and inclined. When the movable member is to be rotated, consequently, the upper and lower wall surfaces of the movable member do not abut on the internal wall surface of a front concave portion of frame members so that the rotation of the movable member is not hindered. Therefore, it is possible to provide an electronic apparatus having a movable member to be used in an on-vehicle acoustic apparatus and rotating a movable member to be accommodated in a frame member even if a clearance between the concave portion of the frame member and the movable member is reduced.Type: ApplicationFiled: August 5, 2003Publication date: February 12, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuhiro Sato, Masatoshi Wakitani

Patent number: 6564352Abstract: To an error detection circuit in a decoder, data is supplied which contains an ECC parity sent from a player side of a disk into a decode system. Syndromes for P- and Q-corrections are calculated based on the data contained in the ECC parity. It is, therefore, possible to detect an error with high accuracy.Type: GrantFiled: September 9, 1999Date of Patent: May 13, 2003Assignee: Kabushiki Kaisha ToshibaInventors: Shinobu Furuhashi, Nobuhiro Sato

Patent number: 6496471Abstract: A disk playback apparatus such as a CD player comprises a case and a lift unit which is supported to be movable in the vertical direction to the case. The lift unit comprises a playback unit, a turntable, a holder drawing member, and the like. A magazine which is adapted to be loaded in the case accommodates therein disk holders, each of which hold one of different-sized disks. A control link having a holder butting pin and a disk control pin is movably mounted on the playback unit which is urged in the direction of departing from the disk by means of a release spring. When the disk holder reaches its accommodation position, the disk holder butts against the holder butting pin and rotates the control link slightly, thereby the disk control pin compulsively corrects the position of the disk. Thus the disk is certainly transported to the normal chucking position on the playback unit irrespective of the disk accommodated state in the disk holder.Type: GrantFiled: October 12, 2000Date of Patent: December 17, 2002Assignee: Clarion Co., Ltd.Inventors: Nobuhiro Sato, Hideki Hayashi

Patent number: 6295104Abstract: In a transparent and spread illuminating apparatus 1, a light reflection pattern 7 consisting of the concave and convex is formed on the front surface 6 of a transparent substrate 2 so that the emission light is allowed to be uniformly irradiated on the face of the transparent substrate 2 regardless of a distance from a light source lamp 4, and the light is facially irradiated on a reflection type liquid crystal display element L. In addition, a transparent member 11 for changing the progressing direction of the light reflected from the transparent substrate 2 is disposed between the reflection type liquid crystal display element L and the transparent substrate 2 so as to be in close contact with both surfaces thereof. As a result, the degradation of the contrast which makes the observation of an image difficult and the generation of the moire pattern can be prevented.Type: GrantFiled: May 24, 1999Date of Patent: September 25, 2001Assignee: Minebea Co., Ltd.Inventors: Motoji Egawa, Nobuhiro Sato, Shingo Suzuki

Patent number: 5459504Abstract: The heat transfer ribbon can be held by a heat transfer ribbon feed roller and a heat transfer ribbon pinch roller and can be fed in the direction opposite to the normal feeding direction for printing and also effectively used even if there appears a large blank space between the printed portions on the paper by returning it by the length corresponding to such a blank space. Furthermore, since the heat transfer ribbon feed roller or the heat transfer ribbon pinch roller is provided with a mechanism for applying turning effort to give directly tension to the heat transfer ribbon, a given tension is always applied to the heat transfer ribbon to thereby prevent the wrinkle from generating thereon even if the outer diameter of the heat transfer ribbon wound around a supply roller is varied. Still furthermore, the heat transfer ribbon pinch roller and the paper pinch roller are integrated with each other to form a pinch roller unit for facilitating the assembly thereof and improving the maintenance thereof.Type: GrantFiled: August 16, 1993Date of Patent: October 17, 1995Assignee: Tohoku Ricoh Co., Ltd.Inventor: Nobuhiro Sato
