IPC: H02G15/02
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent the sheath of a cable end from moving at a low cost by a method wherein a ring is fitted on the sheath of the cable end, the end of the sheath is folded on the ring and the folded sheath end part is tightened by a band and, further, fixed by a heat-shrinkable tube. SOLUTION: First, a wedge-like ring 10 is put on the outer circumference of the sheath 5 of a cable 1 end. The outer circumference of the ring 10 is tapered so as to have a wedge-shape. Slits are formed in the end 5A of the sheath 5 and a plurality of the pieces of the sheath end 5A are folded on the ring 10 into wedge-shapes. After the folded pieces of the sheath end parts 5A are bound and tightened by a band 11, a heat-shrinkable tube 12 is put over the whole folded sheath end and the stripped cable end to fix as a whole. As a result, the movement of the cable end sheath can be avoided by simple components and works and the moisture-proofness and electrical insulating properties of the cable end can be improved at a low cost.

Title: Super-precision polishing device
Inventor: YAGUCHI HIROO
IPC: H01L21/304
Filed: 1986-11-25
Abstract: PURPOSE:To polish up a surface more precisely than an optical surface by a method wherein a surface to be polished is positioned between an anode and cathode in an abrasive liquid containing a small quantity of fluorine calcium carbonate and constituted to properly meet the surface material to be treated and the liquid is stirred with a direct current applied across the two electrodes. CONSTITUTION:An anode 20 and cathode 30 and a silicon wafer 70 positioned between them are placed in a polishing tub 50, and a polishing liquid 10 is stirred by blades 61. When a DC voltage is applied across the two electrodes 20 and 30, fluorine calcium carbonate contained in the polishing liquid 10 is ionized for the generation of fluorine ions 11. The fluorine. ions 11 are negative ions and therefore travel toward the anode 20. However, they first strike the surface of the silicon wafer 70 and then, on their migration further toward the anode 20, are agitated by the blades 61 and strike the surface of the silicon wafer 70 again. Fluorine ions 11 floating in the polishing liquid 10 are thus caused by the rotating blades 61 to repeatedly strike the surface of the silicon wafer 70. The silicon wafer 70, being struck by the ions 11, is removed of surface protrusions, to be gradually polished up to a super-precision scale.
