Title: Magnetic disk device
Inventor: HATTORI TOSHIAKI
IPC: G11B21/02
Filed: 1984-11-12
Abstract: PURPOSE:To fix securely a carriage to a head landing zone by constituting such that a DC solenoid keeps generating force against the elasticity of an elastic body with respect to a stopper during a certain period until the rotation of a DC motor stops. CONSTITUTION:Even if an electric power source +V is interrupted, an electric current flows in the DC solenoid 19, and a solenoid return spring 24 is brought into the stretched state. Until the rotation of the motor 104 attenuates to a certain value, a carriage is not locked. During said state, a return spring 15 rotates the carriage to the inner peripheral side of a magnetic disk 1, and the carriage comes contact with a stopper 10 and stops. Since coils 106 and 107 brake the rotation, the rotational frequency of the DC motor 104 slows gradually. When it drops to the prescribed value, an electric current due to electromotive force cannot stretch the solenoid return spring 24, and a claw ring 21 is fixed by the solenoid return spring 24 and stops by inserting into the groove of a fixed claw 26. The engagement of the claw part suppresses the rotation of the carriage and can be fixed.

Abstract: PURPOSE:To make the title printer head compact, by using a luminous body constituted so that at least a metal film, an electric field light emitting substance layer and a metal film are laminated to a substrate in this order and an electric field is applied between the above-mentioned metal films to emit light from the end surface of the above-mentioned electric field light emitting substance layer and emitting luminous flux in the thickness direction of the substrate by a light guide part. CONSTITUTION:When metal films 2, 4 are used as electrodes and an electric field is applied to an electric field light emitting substance layer 3 by an electric field applying means 5, the emission of light is generated by field light emitting effect. This emitted light is repeatedly reflected in the gap of the metal plates 2, 4 to propagate and emitted from the end surface of said layer 3 as linear luminous flux. This end surface emitted light 7 propagates through a light guide body 6 and is reflected by a wall surface to become the linear luminous flux 7' emitted in the thickness direction of a transparent substrate 1. Said luminous flux 7' is incident to the dot line 11 of a liquid crystal shutter array and subsequently formed into an image on a photosensitive body by a lens array 14. In this luminous body, a light source part can be formed into a thin plate shape as compared with a case using a conventional fluorescent lamp and an optical printer head can be made compact.

Title: Prevention of damage of anode electricity conducting body for electroplating
Inventor: SHIMOGOORI KAZUTOSHI
IPC: C25D21/00
Filed: 1984-11-12
Abstract: PURPOSE:To prevent damage of an anode electricity conducting body by the spark between movable anodes and said body in an electroplating device to use the soluble anodes by pressing the soluble anodes to the anode electricity conducting body to decrease the contact resistance between both and to maintain the potential difference thereof at a specific value or below. CONSTITUTION:A suitable number of unit members 2 of the soluble anodes are disposed, according to the width of a non-plated steel plate, on the anode electricity conducting body 3 made of Ti or Nb in the electrolating device using the soluble anodes. Press plates 9 attached with elastic materials at the bottom end are disposed on both side faces of the plural arrayed unit anode members and both ends are connected by means of bolts 10 to the body 3. Push springs 11 are attached to the bolts 10 in this case. Since the anodes 2 are always kept in press contact with the body 3 by the springs 11, the contact resistance between the anodes 2 and the body 3 does not increase even if the thickness of the anodes 2 decreases on wearing. The potential difference between both is thus maintained always under <=12v and the damage of the body 3 by the spark generated between said body and the anodes 2 is prevented.
