摘要： A method and an apparatus for providing an optical fiber connector or similar workpiece formed of, e.g., glass, ceramic or plastic with a mirror-finished convex tip efficiently is disclosed. While a film-like abrasive tool is conveyed in contact with the wall of a groove formed in a stage, the workpiece is caused to rotate about its axis (and to move in a reciprocating motion). By the resulting grinding operation, the sectional shape (arcuate) of the abrasive tool contacting the wall of the groove is transferred to the end of the workpiece. As a result, the end of the workpiece is provided with a convex tip. The abrasive tool is replaced with an abrasive tool for finishing, as needed.

摘要： A method and an apparatus for forming a hemispherical convex mirror surface on the end of a ferrule or optical fiber connector efficiently and accurately. The apparatus has a grinding wheel having a concave work surface, a tool for correcting the shape of the work surface, a stage for bringing the tool into contact with the wheel, a mechanism for causing the end of the ferrule to contact the work surface, and a mechanism for displacing the axis of the ferrule from the center of the curvature of the arcuate section of the work surface. After the axis of the ferrule has been displaced from the center of the curvature, the ferrule is caused to contact the work surface and roughly ground thereby. Subsequently, after the ferrule axis has been brought into alignment with the center of curvature, the ferrule is sequentially finished from the tip to a preselected point thereof.

摘要： A device for mirror-polishing the end of an optical fiber connector or similar elongate workpiece into a convex shape. A first grindstone polishes the workpiece while a second grindstone corrects the work surface of the first grindstone when it is deformed. The work surfaces of the first and second grindstones run in perpendicular directions or in inclined directions, so that an arcuate concavity having a circular or oval cross-section is formed in the work surface of the first grindstone. Electrolytic dressing is applied to the work surface of the first grindstone to provide it with high processing ability at all times. When the concavity of the first grindstone is deformed, the second grindstone corrects it with the work surface thereof.

摘要： A surface polishing machine includes a polishing tool having a polishing tool face, a pressurizing member, placed on and movable in unison with a workpiece placed on the annular polishing tool, for pressurizing the workpiece toward the polishing tool, and a polishing-position retaining mechanism for holding the workpiece at a predetermined polishing position by preventing it from moving in unison with the polishing tool, while permitting it to rotate, as the polishing tool rotates. To reduce the overall size of the polishing machine and carry out highly accurate polishing, the polishing tool has its diameter larger than the diameter of the workpiece and smaller than twice the workpiece diameter. Alternatively, the polishing tool face is formed with an annular groove coaxially with the center of rotation of the polishing tool so that the annular groove extends to pass through the center of rotation of the workpiece placed on the polishing tool.

摘要： A cross-connect optical switch comprises (a) an input array of optical input paths arranged in a first direction; (b) an output array of optical output paths arranged in a second direction different from the first direction; (c) a switching region formed between an output end of the input array and an input end of the output array; (d) a mirror array of optical reflection mirrors arranged in the switching region; and (e) a mirror driver for driving electromagnetically the mirror array. Each of the mirrors of the mirror array has a reflection plane perpendicular to a bisector between the first and second directions and is supported in such a way as to be displaceable along the reflection plane between a standby position and an operation position. Light beams emitted from the input array are reflected by the corresponding mirrors to be sent to the output array in the operation state, and pass near the corresponding mirrors in the standby state. Switching operation between several hundreds of optical input paths and several hundreds of optical output paths is realized.
