Title: Production of optical fiber and carbon coater
Inventor: SHIMOMICHI TAKESHI
IPC: G02B6/44
Filed: 1989-06-30
Abstract: PURPOSE:To enable stable production of optical fiber coated with carbon coating film by feeding an oxygen-containing gas from the bottom of the reaction tube to remove soot on the inner wall of the reactor by combustion, when carbon thin film is formed on the surface of a bare optical fiber by passing a bare optical fiber through the cylindrical reaction tube and feeding a starting gas forming carbon by decomposition to form a carbon thin film on the surface of the optical fiber. CONSTITUTION:A glass bare line for optical fiber 11 is passed through a cylindrical reaction tube 12 downward from the tube top to the bottom, while a hydrocarbon gas which forms carbon by pyrolysis is fed from the pipe 14. The hydrocarbon gas from the feeding pipe 14 is pyrolyzed in the reaction tube 12 with the heat from the heater 10 outside the tube and the generated carbon forms carbon coating film on the surface of the optical fiber 11. At this time, excess carbon deposits on the lower part of the reaction tube 12 in the form of soot and clogs the exhaustion pipe 15 and an oxygen-containing gas is fed from the inlet 19 to the lower inlet 20 to burn the soot deposited whereby the exhaustion pipe is prevented from being clogged to continue stable production of optical fibers which is coated with carbon coating film.

Title: Surface scraping method of wire rod and device thereof
Inventor: ASAKAWA MOTOO
IPC: B24B5/38
Filed: 1983-09-12
Abstract: PURPOSE:To aim at improvements in a yield rate and stabilization in size and form, by repeatedly reciprocating a cylindrical rotary grinding wheel with its inner surface upon receiving each signal of depth, length and positions of flaw in the wire rod detected by a flaw detector, while grinding the wire rod as being rotated in the circumferential direction. CONSTITUTION:After peeling an oxidized film or the like from the surface, a wire rod 2 is subjected to a primary wire stretching after moiste activation treatment through a die front dry type moiste activator tank, then surface flaw detection for the wire rod takes place in succession by a surface flaw detector 6-1, while on the basis of surface flaw detection, only such a portion as being flawed in its surface is mended with an inner surface of a cylindrical rotary grinding wheel through an internal wheel automatic grinding attachment 7 which grinds the flawed part in a selective manner, and the mended wire rod is rolled on a takeup roller 8 in series. Thus, since a specific circumferential part alone of the wire rod is selectively mendable, mending can be done in a favorable yield rate as compared with a whole circumference cutting method and, what is more, mending warks left behind on the surface are smooth enough in comparison with the case of using a cutting tool or a scalping die, while variations in size and form of the wire rod after mending are little, besides less influence to the next stage of work.

Filed: 1989-06-30
Abstract: PURPOSE:To round a corner part of a groove for element isolation use or for trench capacitor formation use without a need for a heat treatment at a high temperature of 1000 deg.C or higher by a method wherein impurities are introduced into a peripheral part of a region where the groove is to be formed and the corner part of the groove is rounded by utilizing that an etch rate of an impurity-introduced part is made fast. CONSTITUTION:A first silicon oxide film 12 is formed on a p-type silicon substrate 11; after that, a first silicon nitride film 13 is deposited in 6000Angstrom ; a resist pattern having an opening of 1mum in width is formed on the nitride film 13; the nitride film 13 and the oxide film 12 are etched selectively by RIE by making use of the resist pattern as a mask; after that, a resist is removed. Then, the substrate 11 is etched selectively by RIE by making use of the nitride film 13 and the oxide film 12 as a mask; a groove 15 whose width is 1mum and whose depth is 1mum is formed. After that, an isotropic etching operation is executed; since an etch rate differs between an adjacent diffusion layer 14 and an adjacent non-diffusion part during this process, an opening part of the groove 15 becomes a shape that its corner parts are rounded. As a result, even when an oxide film 17 is formed inside the groove 15, it is possible to prevent a stress from being concentrated at the corner parts.
