Patent number: 7106532Abstract: In a hard disk unit, a disassembling and assembling unit disassembles and assembles data in accordance with the size of data to be written from host equipment to the hard disk unit and a sector size and a cluster size as a unit to be read or written. An encoder performs predetermined arithmetic operation to generate a specific bit string as an encoding key based on at least the identification information on the host equipment or on a CPU of the host equipment, and encodes the write data by using the encoding key. The encoding process is performed by flipping bits having a predetermined correspondence with the contents of the encoding.Type: GrantFiled: March 25, 2004Date of Patent: September 12, 2006Assignee: Clarion Co., Ltd.Inventors: Masaaki Hikosaka, Hiroto Handa

Patent number: 6633532Abstract: A tilt adjusting apparatus for a disk drive including a support plate which is fixed to a drive plate, and a skew plate which is fixed to a spindle motor, wherein the support plate and the skew plate is attached to each other with guide screws. The skew plate is tiltably supported by the support plate with the use of helical compression springs. The skew plate has bulged portions which abut on gradient portions formed on support plate. The skew plate also has grooves for receiving guide pins which are fixed to the support plate. An adjuster screw applies force to the skew plate in a tangential direction which is perpendicular to the tracking direction of the optical pickup, and thus performs a tilt adjustment in the tangential direction.Type: GrantFiled: September 12, 2000Date of Patent: October 14, 2003Assignee: Clarion Co., Ltd.Inventor: Hiroto Handa

Patent number: 6010344Abstract: A motor driven ejection system responsive to control signals so as to allow the insertion and/or ejection of a card under computer automatic control. The ejection system has a motor responsive to control signals to cause forward/reverse movements of the motor or render the motor stationary, so that the insertion and the ejection of a card is completely dominated by a computer and not susceptible to any operator interaction that might otherwise damage or distort information on the card.Type: GrantFiled: August 19, 1997Date of Patent: January 4, 2000Assignee: The Whitaker CorporationInventors: Hidenori Muramatsu, Hiroto Handa, Hiroyuki Umezawa, Makoto Hamada

Patent number: 5879175Abstract: A card (12) is inserted by pushing against a rubber roller (44) at the leading end of the card (12). The action of the rubber roller (44) pivots an actuation lever (24) to actuate a switch (36), which, in turn, starts a motor (16). The card (12) is moved inwardly by the rotation of the rubber roller (44) thereby pushing the card against support legs (62) causing a pinion (58) to engage with a rack (56) mounted on a card holder (48). The card holder (48) then holds the card (12) and is driven by the pinion (58) causing hook portions (84a, 84b) of pushing arms (72a, 72b) to engage the trailing edge (12b) of the card (12) thereby connecting the card (12) with contact pins (22) of an electrical connector (20) by pushing the card at its trailing edge.Type: GrantFiled: October 20, 1997Date of Patent: March 9, 1999Assignee: The Whitaker CorporationInventors: Hidenori Muramatsu, Hiroto Handa, Hiroyuki Umezawa, Makoto Hamada

Patent number: 5646926Abstract: A data processing device having a shutter opening and closing mechanism which operates within a path along which a minidisk MD moves to open a shutter only when it is necessary to open the shutter of the MD. A change-over mechanism for diverting the drive force for loading cassettes to the shutter opening and closing mechanism. A recording medium pushing mechanism is arranged to stop a recording medium from being taken out of the magazine to the carrier when there is a recording medium in the carrier. A recording medium take-in/eject mechanism able to reduce the space occupied, and a carrier mechanism which improves the working efficiency during assembly. This makes it possible to provide a data processing device with improved operating properties.Type: GrantFiled: October 12, 1994Date of Patent: July 8, 1997Assignee: Clarion Co., Ltd.Inventors: Hiroto Handa, Hidenori Muramatsu, Nobuhiro Satoh, Satoshi Kanno, Osamu Sakurai
