    • An optical fiber array including a substrate having a grooved portion and a planar portion which are formed integrally on opposite sides of a shoulder, and wherein the grooved portion has a plurality of grooves each defined by two side walls forming a predetermined angle therebetween, and a plurality of optical fibers are accommodated within the respective grooves and supported by the planar portion. Each of the optical fibers accommodated in the grooves is forced onto the two side walls by a covering plate disposed on the grooved portion, and thereby positioned. A gap having a transverse cross sectional surface area S1 is formed between each optical fiber and the upper surface of the substrate, while a gap having a transverse cross sectional surface area S2 is formed between each groove and the optical fiber, such that the area S1 is larger than the area S2, and the gaps between the optical fiber and the substrate and covering plate are filled with an adhesive agent to integrally bond the optical fibers to the substrate.
    • 一种光纤阵列,包括具有沟槽部分和平坦部分的基板,所述基板一体地形成在肩部的相对侧上,并且其中所述带槽部分具有多个槽,每个槽由两个在其间形成预定角度的侧壁限定, 多个光纤容纳在相应的槽内并由平面部分支撑。 容纳在凹槽中的每个光纤通过设置在凹槽部分上的覆盖板而被迫到两个侧壁上,从而定位。 在各光纤与基板的上表面之间形成横截面积为S 1的间隙,在各槽与光纤之间形成有横截面积S 2的间隙, 区域S1大于面积S 2,并且光纤与衬底和覆盖板之间的间隙填充有粘合剂以将光纤整体地结合到衬底。

    • A rope tension measuring apparatus for measuring rope tension of a plurality of main ropes that suspend an elevator car and a counterweight and adjustment quantities of tension adjusting springs for the main ropes. The apparatus comprises a portable measuring device comprising traveling-wave detector means directly attached to the elevator main rope for detecting a traveling wave that is generated by applying an instantaneous displacement to the main rope, traveling-wave passage velocity computing means for measuring the passage velocity of the traveling wave, rope tension computing means for computing the rope tension based on the passage velocity, spring adjustment quantity computing means for computing a spring adjustment quantity for the rope tension adjusting springs, and output means for outputting these computed results, based on the variation of passage velocities of the plurality of main ropes. The apparatus works excellently with a high-lift elevator with its sensor easy to mount, and performs tension adjustment efficiently.
