    • An outer casing of an electric equipment including: a front panel; a base case having a bottom plate portion and a pair of side plate portions; a top case having a roof portion, a pair of side plate portions, a roof portion protruding piece, and a pair of side plate protruding pieces; and a fixing member. A longitudinal width of each of side plate protruding pieces is set smaller than a longitudinal width of the recess portion for a predetermined length. The outer casing further includes a pair of pedestals integrally formed at both end portions of a bottom face of the recess portion with height thereof being set substantially the same as the predetermined length.
    • 一种电气设备的外壳,包括:前面板; 具有底板部分和一对侧板部分的基部壳体; 具有顶部的顶壳,一对侧板部,顶部突出片和一对侧板突出片; 和固定构件。 每个侧板突出片的纵向宽度被设定为小于凹部的纵向宽度预定长度。 外壳还包括一体地形成在凹部的底面的两端部的基座,其高度被设定为与预定长度基本相同。

    • In an optical cable made by forming a sheath on enclosing one or more optical fiber cores and a tension member, high reliability is obtained through the avoidance of adverse effects on the optical fiber core of a curving tendency of the tension member prevailing over the resistance of the sheath to curving (for example, due to the installed optical cable being heated by electrical equipment in proximity) and the optical cable consequently curving. Taking the plane containing the curve formed by the tension member due to its curving tendency as a base plane, the optical fiber core is disposed in the proximity of the position of the image formed when the tension member is projected in a direction perpendicular with respect to the base plane onto a flat plane separate from and parallel with the base plane. If the optical fiber core is an optical fiber ribbon comprising a plurality of optical fibers lined up in a flat plane and coated en bloc, then as an additional condition, an alignment line obtained by joining the centers of the optical fibers at both sides of the optical fiber ribbon is disposed perpendicular to the base plane.
    • 在通过在封闭一个或多个光纤芯和张力构件上形成护套而制成的光缆中,通过避免对光纤芯的不利影响,获得高可靠性,其中拉伸构件的弯曲倾向超过电阻 护套弯曲(例如,由于安装的光缆由靠近的电气设备加热)并且光缆因此弯曲。 将由于弯曲趋势所形成的曲线所包含的平面作为基底面,将光纤芯设置在当张力构件相对于垂直方向投影的方向上形成的图像位置附近时 基板平面与平面平行,与平面平行。 如果光纤芯是包括排列在平面上并整体涂覆的多根光纤的光纤带,则作为附加条件,通过将光纤的中心连接在两侧的光纤 光纤带垂直于基面设置。
