    • The object of the present invention is to provide a wide-band optical fiber coupler whose light-branching ratio is independent of the wavelength of light rays to be transmitted therethrough as well as a method for preparing the wide-band optical fiber coupler. When an optical fiber 1 having zero-dispersion at 1.55 .mu.m band and an optical fiber 2 having zero-dispersion at 1.3 .mu.m band are fused and drawn to form a coupled portion 3, a light beam 15 is incident upon the optical fiber 2 and the intensity of the light beam outgoing through either of these optical fibers 2 or 1 is measured to detect the light-branching ratio observed at the coupled portion 3. The drawing operation is interrupted at an instance when the detected light-branching ratio falls within the range of 50.+-.5%.
    • 本发明的目的是提供一种宽带光纤耦合器,其光分支比率与要透射的光线的波长无关,以及宽带光纤耦合器的制备方法。 当在1.55μm带上具有零色散的光纤1和在1.3μm带上具有零色散的光纤2被熔化和拉制以形成耦合部分3时,光束15入射到光纤2上 并且测量通过这些光纤2或1中的任一个射出的光束的强度,以检测在耦合部分3处观察到的光分支比。在检测到的光分支比落入内部的情况下,绘制操作被中断 范围为50 +/- 5%。

    • An apparatus for changing the wiping range of a wiper enables the wiping range to be changed easily but without involving the risk of unwanted changes. The motor caused movement of the drive link is converted into a movement of the drive link for causing a reciprocating oscillation of wiper arms by first and second links which are each swingably supported, the second link being swingable realtive to the first link in such a manner that the stop position of the wiper arms can be varied. An auxiliary link provided on the first link is swingable while following the relative swinging of the second link and being integrated therewith, with the swinging radius of the auxiliary link being smaller than the relative swinging radius of the second link. A spring is supported by two relatively displaceable points of support that are on a link arm of the auxiliary link and on the second link whereby the spring exerts resilient force under which the second link swings to the appropriate one of a plurality of second link positions.
    • 用于改变刮水器的擦拭范围的装置使得能够容易地改变擦拭范围,而不会引起不希望的变化的风险。 电动机引起的驱动连杆的运动被转换为驱动连杆的运动,从而通过第一和第二连杆可摆动地支撑来引起刮水器臂的往复振动,第二连杆可以以这种方式以第一连杆的方式可转动 可以改变刮水器臂的停止位置。 设置在第一连杆上的辅助连杆可以在跟随第二连杆的相对摆动并与其一体化的同时摆动,辅助连杆的摆动半径小于第二连杆的相对摆动半径。 弹簧由两个可相对移动的支撑点支撑,该支撑点位于辅助连杆的连杆臂上并在第二连杆上,由此弹簧施加弹性力,在该弹性力下第二连杆摆动到多个第二连杆位置中适当的一个。
