Title: Method and device for drawing optical fiber preform
Inventor: HOSHINO SUMIO
IPC: C03B37/018
Filed: 1992-07-21
Abstract: PURPOSE:To provide a method and device for drawing so that, especially, even a large-size optical fiber preform can be easily drawn. CONSTITUTION:Both ends of the optical fiber preform are provided with dummy bars in one body, and each dummy bar is inserted to the respective upper or lower engaging member. While the upper and lower engaging members are held with upper and lower chucks, drawing is started in a heating furnace. After this, the chucking position for the upper or lower chucks are changed from the engaging member to other positions. It is preferable to use auxiliary chucks in the process of changing the chucking position. The device for drawing is equipped with chucks above and under the heating furnace which can independently move in the axial direction of the heating furnace, and further equipped with auxiliary chucks which can move between the furnace and the lower chuck. Thus, even a large-size preform can be drawn without bending while the height of the equipment is suppressed.

Inventor: TSUTSUMI KENJI
IPC: G06F3/06
Filed: 1993-08-05
Abstract: PURPOSE:To provide a disk array device capable of quickly executing restoring work without deteriorating a response to a host. CONSTITUTION:The disk array device 11 is constituted of plural disk devices 141 to 144 each of which is provided with two recording/reproducing mechanisms for having access to the same surface of a disk medium.

IPC: G03G5/16
Filed: 1988-08-04
Abstract: PURPOSE:To miniaturize a device with a simple constitution and to print with high accuracy by attracting magnetic ink only in an area exposed by the exposure means of a photosensitive body constituted of a superconductor. CONSTITUTION:The device provides the photosensitive body 20 which at least photosensitive surface is constituted of a superconductor, a cooling means 21 which brings the photosensitive body 20 into a superconducting condition, and the exposure means 24 which stores information on the photosensitive material 20. The information is written by the photosensitive means, and the magnetic ink 23 is made adhered to the photosensitive body 20 when its written area becomes normally conductive, and then, an image is developed. Thus, unlike the conventional method, a high electric field which electrifies or destaticizes the photosensitive body and transfers an image thereto is not required any more, therefore, a device can be miniaturized. Nor without need of a constitution which uniformly electrifies toner, etc., nor a heating means because of wet, the constitution of a device becomes very simple. In addition, since the magnetic fluid of <=1mum is used for the ink material, very fine print is possible.
