Airtight perforated section for optical fiber
专利汇可以提供Airtight perforated section for optical fiber专利检索，专利查询，专利分析的服务。并且PURPOSE:To constitute airtight perforated sections for optical fibers, by oppositely installing two glass rods having a flat surface at the bottom and a spherical surface at the top in transmission lines for instrumentation signals of a nuclear reactor, etc., and by installing a metallized layer on the side face of at least one glass rod. CONSTITUTION:Glass rods 3 and 3' are formed to have a flat surface at the bottom and a spherical surface at the top, and they are installed in such a way that their spherical surfaces face to each other. To the bottom of the rods 3 and 3', glass fibers 2 and 2' are firmly connected, respectively, and the connected part is mechanically reinforced. Moreover, a metallized layer 4 is installed on the side face of one or both rods 3 and 3', and one rod 3 is connected to a holding material 9 and another rod 3' is connected to a fitting plate 7 by soldering 5 through a metallic sleeve 6. When the fitting plate 7 is connected to a wall of a container 1 by welding and the holding material 9 is fitted to the fitting plate 7, an airtight perforated section is constituted. When this constitution is used, an optical signal passing through the fiber 2 spreads through the rod 3 with a wide angle, and then passes through the gas as a parallel ray. When the ray reaches the surface of the rod 3', the ray is converged into the bottom surface of the rod 3', and then, transmitted through the fiber 2'.，下面是Airtight perforated section for optical fiber专利的具体信息内容。
