摘要： PURPOSE:To utilize one kind of mechanism for two kinds of operation and to evade a component breakage accident by allowing a butting plate to penetrate the matching liquid coating hole of a matching liquid supplier vertically and providing a descent position adjusting means for the butting plate to a butting plate moving device, and combining it with the butting plate mutually. CONSTITUTION:When the end surface gap between optical fibers F1 and F2 is set, a cam 13 is rotated by a motor 12 in a specific direction to elevate the butting plate 3 through the cam 13 until its 1st front end part 3a moves to the butting position of an optical fiber end surface, which is allowed to but on the front end part 3a. In this case, when the optical fiber end surface is coated with matching liquid L, the projection piece 3d of the butting plate 3 is brought into contact with the cam surface 14 of the cam 13 at a point P1 as shown in a figure, and then the slit 9 at the 1st front end part 3a of the butting plate 3 is fitted in the matching liquid coating hole 6 of the matching liquid supplier 4 to stick the matching liquid L on the 1st front end part 3a through the slit 9 by a specific amount. On the other hand, when the end surface gap is set without applying the matching liquid L to the optical fiber end surface, the projection pieces 3d of the butting plate 3 is brought into contact with the cam surface 14 of the cam 13 at a point P2 as shown in a figure (a) and the slit 9 at the 1st front end part 3d is fitted in the matching liquid coating hole 6, so that the matching liquid L does not stick on the 1st front end part 3a of the butting plate 3.
摘要翻译：目的：利用一种机制进行两种操作，并通过允许对接板垂直穿过匹配液体供应器的匹配液体涂层孔来避免部件破损事故，并提供对接板的下降位置调整装置对接板移动装置，并将其与对接板相互组合。构成：当光纤F1和F2之间的端面间隙被设定时，凸轮13通过马达12沿特定方向旋转，以通过凸轮13升高对接板3，直到其第一前端部分3a移动到对接位于前端部3a的光纤端面的位置。在这种情况下，当光纤端面涂覆有匹配的液体L时，如图所示，对接板3的突出片3d与凸轮13的凸轮表面14接触，如图所示，然后将对接板3的第一前端部分3a处的狭缝9装配在匹配液体供应器4的匹配液体涂覆孔6中，以通过狭缝9将匹配液体L通过狭缝9粘贴在第一前端部分3a上具体数量。另一方面，当在不将匹配液体L施加到光纤端面的情况下设定端面间隙时，对接板3的突起片3d与凸轮13的凸轮面14接触 P2如图（a）所示，并且第一前端部3d的狭缝9嵌合在匹配液体涂布孔6中，使得匹配液体L不粘附在对接板的第一前端部3a上 3。

摘要： PURPOSE:To reduce a bend of a core after an optical fiber has been welded and connected, and to execute a connection at a low loss by measuring a shift of the center of the optical fiber, and varying one or both of a time of an electric discharge or an electric power in accordance with a size of the shift. CONSTITUTION:For instance, a TV camera is installed to a microscope 22, data of scanning lines 32, 34 are processed by a computer, and shifts d1, d2 between the centers in fiber images 10x, 10y, and a shift (a) which has synthesized them, namely, (d1 +d2 ) are derived. For instance, when a current is kept constant as 17mA, and the shift (a) is 1mum at the maximum, the discharge time is set to one second, and when the shift (a) is >=4mum, said time is kept constant as 0.5sec. Also, during that time, the time is varied in accordance with the shift (a). In this way, while the shift (a) is between 1mum and 4mum, a bend of a core after welding and connection becomes almost the same extent.

Subsequently, the V- groove 20 is shifted excessively by an intentional shift quantity DELTAd, and discharged and heated. In this way, d1 of the time when the axial matching of the core has been ended is known, and accordingly, the discharge heating is executed by giving in advance an axial shift by d1+DELTAd intentionally to the optical fiber, so that the axial shift between the optical fibers of the time when the connection has been ended becomes d1.

摘要： PURPOSE:To obtain a melt-sticking connection method whose connection loss is low by connecting cores by melt-sticking after uniting the axial centers of cores and operating the holders of optical fibers while heating the melt-stuck part so that the cores are arranged straightly. CONSTITUTION:Single mode optical fibers A1 and A2 to be connected are set on holders 1 and 2 and these connecting ends 3 and 4 are opposed by separating them only by a slight space. While monitoring the light transmitted through the fibers with a light source 5 such as a semiconductor laser and a light detector 6, the axial centers of cores B1 and B2 are united by controlling the positions of connecting ends 3 and 4. The connecting ends 3 and 4 are arc welded with a pair of electrodes 7 and 8. In order to compensate the curve of cores B1 and B2 in melt-stuck part C, arc is generated again on the melt-sticking part with the pair of electrodes 7 and 8 to heat the welding part and the optical fiber A1 or A2 are moved slightly to the horizontal or vertical direction. Since the curve of cores can be compensated by the above-mentioned procedure, melt-sticking connection with low connection loss is made available.
