    摘要: For drawing an optical fiber from an optical fiber preform there are provided means for heating an optical fiber preform, means for pulling out an optical fiber from the optical fiber preform whose fore end part has been fused by heating, and means for causing gas to flow along the outer peripheral surface of the fused part of the optical fiber preform. By further controlling the flow rate of the gas and/or the pulling-out velocity for the optical fiber according to fluctuations in the fiber diameter of the optical fiber, an optical fiber of uniform fiber diameter is easily provided.

    摘要: An electroconductive molybdenum paste comprising 100 parts by weight of a mixture consisting of 68.0 to 89.2% by weight of molybdenum powders having an average particle size of 0.5 to 10 .mu.m, 10.0 to 27.0% by weight of a solvent, and 0.8 to 5.0% by weight of a binder, 0.5 to 5.0 parts by weight of a gelling agent, and 0.5 to 4.0 parts by weight of a silane coupling agent can firmly fill throughholes of a green sheet without formation of clearances and hollows in the resulting conductors in the throughholes, with better surface roughness of the conductor surfaces in the throughholes, and without development of cracks near the throughholes.
