摘要： A method for producing a silica glass optical fiber, which comprises coating carbon on the optical fiber with the use of the remaining heat of not less than 800.degree. C. possessed by the optical fiber just after heat wire drawing, for thermal decomposition of a carbon coat-forming gas comprised of one or more members selected from the group of halogenated hydrocarbons, hydrocarbons, and halogen molecules, which has 5 to 15 hydrogen atoms per 10 halogen atoms, and a reaction apparatus for coating carbon, wherein the area of the outer end of an exhaust region is greater than the transverse sectional area of a coating region, and the outer end is outwardly opened. The production method and the reaction apparatus therefor of the present invention are advantageous in that the optical fiber thus obtained has superior properties in terms of resistance to water, resistance to hydrogen, and mechanical strength, specifically tensile strength, that sedimentation of the soot component in the reaction apparatus can be prevented, that the flow of the material gas can be made smooth, that a uniform carbon coat can be formed on the surface of the optical fiber, and that long-term operation of carbon coating apparatus can be made possible.

摘要： An apparatus for driving a chain in which expansion and contraction of the chain due to an angular position of a sprocket is eliminated, the tensile stress imposed to the chain is reduced so that the chain travels smoothly. A guide cam is provided, which has a guide groove, one end of which is opened at a predetermined peripheral position of a sprocket where the rollers of the chain are released from the sprocket. The cam guides the rollers of the chain so that a winding angle of the chain around the sprocket is kept at a constant value and a constant traveling orbit is maintained irrespective to the angular direction of the sprocket.
