Patent number: 7921434Abstract: When a normal disk having the diameter of 12 cm is inserted into the disk device, first and second optical detecting elements detect the insertion, and transitions to a first detection state, which initiates transfer operation of first and second transfer rollers. If the disk is further moved to an inner portion of the device, thus pressing first and second detecting pins, first and second detecting switches are turned OFF, and the detecting elements enter a second detection state. Before the transition from the first detection state to the second detection state occurs, a rotating speed of the first and second transfer rollers is set low. After transition to the second detection state, the rotating speed is increased. As a result, a card or other such foreign objects can be removed and a monitoring period can be increased until detection of a normal disk is detected.Type: GrantFiled: March 27, 2009Date of Patent: April 5, 2011Assignees: Alpine Electronics, Inc., Toshiba Alpine Automotive Technology, Inc.Inventors: Tsutomu Tatekawa, Tokio Suzuki, Ichiro Kato, Hiroshi Kawase, Yusuke Yoshida, Nobunori Kudou, Yousuke Kuno

Patent number: 7472403Abstract: In a disk-storing disk device according to the present invention, within a casing having an insertion opening formed on the front face for inserting a disk, a plurality of holders are arranged in piles disproportionately on the X1 side about an insertion center line while a drive unit is rotatably supported on the X2 side from the insertion center line. When any of the holders is selected and a disk is inserted through the insertion opening, the disk is clamped to transfer rollers. A transporting unit is counterclockwise rotated while the disk is transferred with the transfer rollers. By the rotation, the disk is securely conveyed to the holder arranged disproportionately on the X1 side. Thereby, efficiency of arranging respective units in the casing is improved so as to provide a disk-storing disk device with short depth size.Type: GrantFiled: March 21, 2006Date of Patent: December 30, 2008Assignee: Alpine Electronics, Inc.Inventors: Tsutomu Tatekawa, Shoji Suzuki, Tokio Suzuki

Patent number: 6071199Abstract: In order to correct a golf swing, a main grip formed at an end portion of a shaft of a golf club is held by a hand opposite to a writing hand of a user, and an auxiliary grip attached to a middle of the shaft is held by the writing hand of the user. While holding the main and auxiliary grips by the left and right hands, the shaft is swung. The auxiliary grip is located near and substantially parallel to the main grip and is disposed at a side ahead of the main grip in a swinging direction of the golf club to be spaced from the main grip for a predetermined space. Thus, when the main and auxiliary grips are grasped by left and right hands, the backs of the left and right hands contact each other between the main and auxiliary grips to restrain a wrist of the writing hand by the back of the hand opposite to the writing hand. Accordingly, the correct swing of the golf club can be practiced.Type: GrantFiled: November 12, 1997Date of Patent: June 6, 2000Inventor: Tokio Suzuki
