Title: Tape recorder
Inventor: IIZUKA GENICHI
IPC: G11B15/675
Filed: 1986-01-14
Abstract: PURPOSE:To simplify remarkably a drive mechanism and also to reduce the weight of a sliding part by using a drive gear which is driven by a single motor to slide a mechanical chassis and to revolve a cassette holding part. CONSTITUTION:A mechanical chassis 4 containing a recording/reproducing part 11 and a cassette holding part 37 is supported in a front-back slidable way. A drive gear 53 engages a gear part 16 of the chassis 4 and a gear part 29 formed at the tip of a rotary arm 26 of the part 37 engages the 2nd rack part 20 of the part 16. In such a constitution, the chassis 4 is pulled out forward with revolution of the gear 53 and the arm 26 is turned upward via both parts 20 and 29 when a pin 43 to be guided of the arm 26 reaches a vertical guide part 45b. Under such conditions, a cassette is loaded. Thus the greater part of a drive part is set within an outer enclosure 2 and therefore the weight of a sliding part is reduced. At the same time, the drive mechanism of a tape recorder is remarkably simplified.

Abstract: PURPOSE:To form a guard ring which is broken down by a required voltage by a method wherein a semiconductor substrate surface is covered with an oxide film beforehand and impurity is introduced into a required region by ion implantation through the oxide film to form a guard ring. CONSTITUTION:A part of an oxide film 3 on a guard ring part into which acceptor impurity is to be introduced is selectively removed and then an oxide film 8 is formed. The acceptor impurity is implanted through the oxide film 8 and a strain created by the ion implantation is relieved by a thermal treatment to form a guard ring p<+>-type layer 4.

Filed: 1987-01-16
Abstract: PURPOSE:To wind a coil with the bearing force averaged in the width direction by covering a sleeve on a tension reel and forming a crown recessing in a parabolic shape on the sleeve. CONSTITUTION:A cold rolled steel plate coil 11 is wound on the tension reel to which a sleeve 14 is fitted via a bridle roll 12. On this sleeve 14, the crown recessed in a parabolic shape is formed along the direction intersecting at right angles with the coil progressing direction.
