Patent number: 5937391Abstract: A service system in an online shopping mall established through a network realizes an improvement of a service to a customer by not having to carry a magnetic card and shortening a time from issuing points to redeeming points. To attain the objects of the system, a points issuing unit issues points corresponding to the purchase amount of a customer. A points storage device stores the number of points accumulated by the customer. A points redeeming unit reduces a purchase amount of the customer as points to be redeemed. A points issue ratio and a points redeeming ratio can be set for each shop forming part of the online shopping mall.Type: GrantFiled: May 29, 1997Date of Patent: August 10, 1999Assignee: Fujitsu LimitedInventors: Sekio Ikeda, Nobuo Oka, Masao Fujiwara, Michihiro Miyasaka, Shuji Morita, Masakazu Yamashita, Yuka Egashira

Patent number: 5610900Abstract: An upper clamping device and a lower clamping device are provided for clamping a double-sided optical disc in cooperation with the upper clamping device. An annular holder is axially movably provided in the upper clamping device. A plurality of spheres are radially movably mounted on the holder. A hub having a slant at a periphery thereof is axially movably provided. When the hub is downwardly moved the slant urges the spheres to engage them with an inside wall of a center hole of the optical disc. Thus, the optical disc is centered.Type: GrantFiled: May 19, 1995Date of Patent: March 11, 1997Assignee: Pioneer Electronic CorporationInventors: Masakazu Yamashita, Shigeharu Furusawa, Masao Abe, Tomohiro Mizuno, Hidekatsu Miyasaka

Patent number: 5504729Abstract: A compatible disc player includes a first tray for carrying an LD arranged to protrude and withdraw from and into a player housing and a second tray for carrying a CD mounted on the first tray, in such a manner as to be movable in directions of the movement of the first tray, and the first and second trays are latched or released to and from each other by use of a latch mechanism in response to a selected one of an LD playing mode and a CD playing mode. The disc player is provided with a single position signal generating switch for sensing positions of the trays, for example, a position in which the trays are completely protruded, and the timing of operation of the switch is changed depending on whether the first tray is moved or the second tray only is moved. Further, the operation of the latch mechanism is controlled by an engagement of a pickup of the player with the latch mechanism.Type: GrantFiled: November 9, 1992Date of Patent: April 2, 1996Assignee: Pioneer Electronic CorporationInventors: Yuji Ikedo, Isami Kenmotsu, Masakazu Yamashita, Shogo Sato, Tomohiro Mizuno

Patent number: 5036507Abstract: A tilting mechanism for the optical pickup unit of an optical information record/playback apparatus such as a video disk player. The optical pickup and a support member for slidably supporting the pickup are tilted together by a tilting servocontrol. The tilting mechanism includes a movable fulcrum about which the optical pickup and the support member are tilted. The fulcrum is moved depending on the position of the optical pickup or on a focusing error signal, so that the tilting servo-control is performed when the fulcrum is in an appropriate position with respect to the distance between the pickup and the disk.Type: GrantFiled: November 1, 1989Date of Patent: July 30, 1991Assignee: Pioneer Electronic CorporationInventor: Masakazu Yamashita

Patent number: 4949328Abstract: A front loading type disk player which can play both sides of a single disk without ejecting the disk from and reinserting it into the disk player after playing one side. In addition, the disk player can play one or both sides of multiple disks without ejecting or reinserting disks. The disk player includes a movable carrier on which at least two trays are movably mounted. The carrier can be moved in a first direction so as to project from or retract into a housing of the disk player, and the trays can be moved in the first direction with respect to the carrier and a second, vertical direction e.g. perpendicular to the first direction. The trays are moved by moving a chassis, which supports them, with respect to the carrier. The trays are independently movable in the first direction and the chassis 11 is movable in the vertical direction in a stepwise fashion so that the disks stored on the trays can be properly individually placed on the turntable and removed therefrom.Type: GrantFiled: August 10, 1988Date of Patent: August 14, 1990Assignee: Pioneer Electronic CorporationInventors: Masao Kase, Toshiaki Koizumi, Masatsugu Otaki, Masakazu Yamashita, Kenji Tanaka, Ryo Matsuura
