    • A slit is formed in a plunger of a limit switch in such a manner that an amount of light incident on a light receiving element is changed in accordance with displacement of the plunger. The limit switch is provided with a setting processing unit (123) for setting a voltage value outputted from the light receiving element as a threshold value when a setting instruction is inputted in a state where the plunger is displaced to a designated position by a user, a position detecting unit (113) for performing detection processing of detecting whether or not the plunger is placed at a closer position to a reference position than to the designated position by comparing the set threshold value and the voltage value outputted from the light receiving element, and an output signal controlling unit (119) for outputting a signal based on a result of the detection processing. Thereby, the switch for outputting the signal in accordance with a position of a displacement member, the switch being capable of easily outputting the signal in accordance with a desired position of the displacement member without need for an adjusting screw can be provided.

    • Even if a fiber fuse phenomenon occurs to start fire spreading, the fire spreading is shut off. A graded index fiber (GIF) 3 is inserted between transmission-use single mode fibers (SMF) 2a, 2b on a fiber optics transmission line 1. The GIF 3 is so designed that its mode field diameter (MFD) gradually increases from a light entry side. The MFD exhibits a maximum value at a location ¼ of a pitch from the end of the GIF 3. A GIF 3a is disposed on the light entry side. A GIF 3b having an MFD gradually decreasing is disposed on the opposite side of the GIF 3a. The GIF 3b is disposed on the light exit side. The lengths of the GIF 3a and GIF 3b are ¼ of a pitch. The length of the GIF 3 formed by connecting the both is ½ of a pitch. According to the present invention, an expanded MFD is inserted in the middle of the fiber optics transmission line, it is possible to shut off fire spreading caused due to fiber fuse phenomenon.
    • 即使发生光纤熔丝现象开始火蔓延,火焰蔓延也被切断。 在光纤传输线1上的传输使用单模光纤(SMF)2a,2b之间插入渐变折射率光纤(GIF)3。 GIF 3被设计成使得其模场直径(MFD)从光入射侧逐渐增加。 在距离GIF 3结束处的间距的1/4处,MFD显示最大值。 GIF3a设置在光入射侧。 具有MFD逐渐减小的GIF3b设置在GIF3a的相对侧。 GIF3b设置在光出射侧。 GIF 3 a和GIF 3 b的长度是1/4的1/4。 通过连接两者形成的GIF 3的长度是音高的1/2。 根据本发明,在光纤传输线的中间插入扩展的MFD,可以切断由于光纤熔丝现象引起的火焰蔓延。
