Title: Reinforcing tube for optical fibers
Inventor: HIRATSUKA TOSHIO
IPC: H01P3/00
Filed: 1978-03-17
Abstract: PURPOSE: To make the tube usable for applications such as optical cords by braiding the specific reinforcing members arrayed linear and weft composed of inorganic fibers such as glass or the like to a tubular braiding and applying plastic vovering thereon.  
     CONSTITUTION: At the time when 24 strings of inorganic alkaline glass fiber  bundles 1 are going to be braided with a braiding machine, 6 strings of the fiber bundles composed of material smaller in elongation by tension than glass are woven as reinforcing members 2 between the fiber bundles 1 so as to be disposed evenly in the circumferential direction and linearly in the length direction, whereby the  tubular braiding of, e.g. inside diameter 1.0 mm and outside diameter 2.0 mm is formed. Next, the surface is covered with heat-resisting polyvinyl chloride 3, whereby the reinforcing tube of inside diameter 1.0 mm and outside diameter 3.0 mm for optical fibers is obtained. Thereby, the optical fiber is protected from tensile stress and the stress in its diameteral direction and since the slippery characteristic of the inside surface of the hollow bore is high, the insertion of the optical fiber is easy.

Title: Surface treatment of heat radiating body
Inventor: INUZUKA NORIHIKO
IPC: C25D11/18
Filed: 1980-03-11
Abstract: PURPOSE: To enhance the boiling cooling characteristic of the heat radiating body by method wherein an anodic oxide film of specified thickness is formed on the radiating surface of the heat radiating body consisting mainly of Al and then a thermal shock is applied to the body and the film to generate minute cracks in the film.  
     CONSTITUTION: Electrolysis is conducted in a sulfuric acid solution under appropriate conditions while using the heat radiating body 2 consisting mainly of Al as an anode, whereby the anodic oxide film 10 of 50W200μ in thickness is produced on the radiating surface 9 of the body 2. When the thermal shock is applied to the body 2 and the film 10 by quenching the body 2 in water after heating the body 2, a plurality of thin groove-shaped cracks 11 extending to the subsrate are produced in the film 10 due to the large difference between the coefficient of thermal expansion of the substrate and that of the film 10. Accordingly, the generation and growth of bubbles from the cracks 11 at the surface of the body 2 are promoted, leading to an enhanced coefficient of boiling heat transfer.
