Patent number: 6657620Abstract: There is provided a flat panel type display apparatus which is superior in heat radiation, withstand voltage characteristic, and the like. A flexible substrate having driving devices for driving a display body mounted thereon is provided on the back surface of a metal chassis which supports the display body at the back surface thereof. The back surfaces of substrates of the driving devices which are semiconductor integrated circuit devices are polished to remove unnecessary oxide films therefrom, and formed of metal films on the back surfaces. The driving devices are disposed on the flexible substrate with the metal films facing upward, a solder paste is coated on the surfaces of the metal films and the surfaces of grounding wiring patterns formed on the flexible substrate, and a metal plate is disposed on both members through the solder paste.Type: GrantFiled: March 16, 2001Date of Patent: December 2, 2003Assignees: Pioneer Corporation, Pioneer Display Products CorporationInventors: Toshiharu Oishi, Tamotsu Harada, Masakazu Kurumada

Patent number: 6366264Abstract: The present invention includes a structure for mounting the driver module of a flat panel display to its display panel such that the depth and width of the display can be made smaller than in a conventional flat panel display. A flexible printed circuit extends from its position mounted to a PDP glass panel along a side surface of a metallic chassis and is bent to a direction vertical to the glass panel such that the flexible printed circuit extends rearwardly. An IC chip and a chip capacitor are disposed between a straight portion of the flexible printed circuit and a side surface of the chassis and connected with the flexible printed circuit.Type: GrantFiled: August 4, 1999Date of Patent: April 2, 2002Assignees: Pioneer Electronic Corporation, Shizuoka Pioneer Electrojic CorporationInventor: Masakazu Kurumada

Patent number: 5036509Abstract: A disc reproducing apparatus is disclosed in which a disc is delivered from a disc inserting opening to a predetermined position within a player, a clamper arm that extends over a turntable for clamping the disc is operated to fix the disc on the turntable, and then the turntable is rotated to reproduce information recorded in the disc. A disc guide plate is pivotally mounted to the clamper arm such that the disc guide plate engages and disengages the clamper arm. A disc guiding recess into which a small-diameter disc can be fitted is provided to the disc guide plate. When the small-diameter disc is delivered, the small-diameter disc is fitted into the disc guiding recess to be aligned with a clamp position, and when a large-diameter disc is delivered, the large-diameter disc pushes the disc guide plate away to be aligned with the clamp position on the turntable.Type: GrantFiled: March 13, 1990Date of Patent: July 30, 1991Assignee: Pioneer Electronic CorporationInventors: Kazuo Kobayashi, Yoshinori Yamada, Kiyoshi Morikawa, Masakazu Kurumada, Masanori Sugihara

Patent number: 5031171Abstract: A disc reproducing apparatus is disclosed in which a large- or small-diameter disc inserted through a disc inserting opening is transferred to a predetermined position within a player, a clamper arm extending over a turntable on which the disc is placed is operated to fix the disc onto the turntable, and information recorded in the disc is reproduced by rotating the turntable. A pair of stopper arms are disposed on the clamper arm, each of which having an abutment which abuts the periphery of the disc. The pair of stopper arms are disposed such that when the small-diameter disc arrives at the predetermined position on the turntable, the angle made by the longitudinal axis of the respective stopper arms is smaller than the angle made by the radial lines connecting each stopper and the center of the small-diameter disc, but greater than the angle made by the radial lines connecting each stopper and the center of the large-diameter disc when the large-diameter disc is place.Type: GrantFiled: March 27, 1990Date of Patent: July 9, 1991Assignee: Pioneer Electronic CorporationInventors: Masakazu Kurumada, Kiyoshi Morikawa, Kazuo Kobayashi, Yoshinori Yamada, Masanori Sugihara

Patent number: 5010484Abstract: A disc reproducing apparatus is disclosed in which a large or small disc inserted through a disc inserting opening is transferred to a predetermined position within a player, a clamper arm extending over a turntable on which the disc is placed is operated to fix the disc onto the turntable, and information recorded in the disc is reproduced by rotating the turntable. A disc guide plate for guiding the small-diameter disc to a clamp position is pivotally mounted to the clamper arm. A disc guiding recess is provided into which the small disc can slip and which has a sufficiently wide opening. A restraining member blocks the advancement of only the large disc into the disc guiding recess. When the small disc is inserted through the disc inserting opening, the small-diameter disc is advanced into the disc guiding recess to be positioned at the clamp position.Type: GrantFiled: March 30, 1990Date of Patent: April 23, 1991Assignee: Pioneer Electronic CorporationInventors: Kazuo Kobayashi, Kiyoshi Morikawa, Yoshinori Yamada, Masakazu Kurumada, Masanori Sugihara
