摘要： PROBLEM TO BE SOLVED: To provide a novel means capable of suppressing damage to a front end surface of a single core optical fiber. SOLUTION: A polishing member 25 includes a polishing part 25a exerting a polishing action, and a protection part 25b not exerting a polishing action. An optical fiber F is elastically transformed by a driving mechanism with the tip of the optical fiber F abutting on the protection part 25b of the polishing member. Thereafter the tip of the optical fiber F is allowed to abut on the polishing part 25a with the axis of the tip of the optical fiber F not perpendicular to the surface of the polishing part 25a. Therefore, the abutting between the front end surface of the optical fiber F and the polishing part 25a is suppressed, and the damage to the front end surface is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an optical connector end machining device, simply and accurately performing machining. SOLUTION: The shape of a holding part 7 is determined so that the center of rotation of the holding part 7 is different from the center of a ferrule. Therefore, a locus of the optical connector 1 (the ferrule 3) on a polishing platen 9 is as shown in Fig.3(c). Since the optical fiber 2 is machined by the polishing platen 9 while taking the locus, finally the optical fiber 2 is not projected from the ferrule 3. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To restrain damage of the front end face of an optical fiber in a chamfering process without complicating the structure of a holder. SOLUTION: A polishing surface 24 of a polishing member 10 intersects with the axis of an intermediate part of an optical fiber F, and also inclines to the orthogonal plane of the axis of the intermediate part of the optical fiber F. When optical fiber F is made to approach the polishing surface 24, the tip of the optical fiber F obliquely comes into contact with the polishing surface 24, and also in separating, the tip of the optical fiber F separates from the polishing surface 24 while keeping its oblique attitude to the polishing surface, so that damage of the front end face of the optical fiber F can be restrained. Since the track of the polishing member 10 includes a revolution component and a rotation component, a large polishing amount can be obtained and also abrasion of the polishing member 10 can be restrained, although the position of the tip of the optical fiber F is in the vicinity of a revolution axis (ar).

摘要翻译：要解决的问题：在倒角过程中抑制光纤前端面的损伤而不会使保持器的结构复杂化。解决方案：抛光构件10的抛光表面24与光纤F的中间部分的轴线相交，并且也倾斜到光纤F的中间部分的轴线的正交平面。当光学使纤维F接近研磨面24，光纤F的前端倾斜地与研磨面24接触，并且在分离时，光纤F的前端与研磨面24分离，同时保持其倾斜对抛光面的姿态，能够抑制光纤F的前端面的损伤。由于抛光构件10的轨道包括旋转分量和旋转分量，所以可以获得大的抛光量，并且即使光纤F的尖端的位置在...中，也可以抑制抛光构件10的磨损旋转轴（ar）附近。版权所有（C）2009，JPO＆INPIT

SOLUTION: A core wire 9 is inserted into an extension member 50 of a plug 4 set on a main body 1. Upper end surfaces 5a (guide surfaces) of a pair of guide projection streaks are extended while offset upward from a guide groove 3a, so a tip portion of the core wire 9 is held obliquely to the guide groove 3a and elastically curved to correct the attitude of the tip portion. The respective upper end surfaces 5a are made parallel to the guide groove 3a, so the attitude of the core wire 9 can be maintained before and after the core wire 9 is shifted in holding point along the upper end surfaces 5a of the guide projection streaks 5.

摘要： PROBLEM TO BE SOLVED: To form a chamfered shape having superior symmetry and out-of-roundness in the tip end of each optical fiber. SOLUTION: Each time a polishing locus makes a round, the locus is shifted by dy stepwise. Even if a circular locus of taper processing is repeated, the overlap of the polishing locus in the X direction (parallel direction) is suppressed. The overlap of the polishing locus in the Y direction (orthogonal direction) is also released, making the overlap only a few times at the maximum. Consequently, deterioration of polishing ability on the polishing face is very little both in parallel and orthogonal directions, so that a chamfered shape with the extremely superior core symmetry and out-of-roundness is formed in the tip end of each optical fiber.

摘要翻译：要解决的问题：形成在每个光纤的末端具有优异的对称性和不圆度的倒角形状。
解决方案：抛光轨迹每次抛光时，轨迹都会逐步移动。即使重复进行圆锥处理的圆弧轨迹，也能够抑制X方向（平行方向）的研磨轨迹的重叠。抛光轨迹在Y方向（正交方向）上的重叠也被释放，使得最大重叠仅几次。因此，研磨面的研磨能力的下降在平行和正交的方向上都很小，因此在每个光纤的末端形成具有非常优异的芯对称性和不圆度的倒角形状。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enhance the yield and to reduce manufacturing cost while preventing the deterioration of optical coupling characteristic in optical fibers. SOLUTION: In moving an optical fiber on the basis of the detection result of the presence and no presence of an optical fiber; after the detection state of the optical fiber is reversed, the movement is repeated several times while the moving quantity is gradually decreased and then, the tip end position of the optical fiber is detected at the position at which the moving quantity becomes a prescribed threshold value or below. Also, the optical fiber is rotated successively at a plurality of different angles and held, the tip end position of the optical fiber is detected each time as above, and an eccentric quantity from the rotating center of the optical fiber is determined by the detection data. Thus, a correction value for the push-in quantity of the optical fiber is calculated which is required for the holding angle at the time of machining. Using this correction value, the optical fiber is controlled so that it is accurately pushed in by a prescribed quantity. COPYRIGHT: (C)2005,JPO&NCIPI
