摘要： An end-face lapping apparatus, comprises a rod member W supported on an apparatus main body by a support mechanism through a fixing jig board. A lapping board has a lapping member for lapping the rod member and is rotatably swingably supported on the apparatus main body by a drive mechanism. The drive mechanism causes the lapping board to rotate about a first rotating center and at the same time swivel rotating center about a second rotating center to thereby carry out lapping while urging the rod member W fitted in the fixing jig board against the lapping member of the rotatably swinging lapping board by the support mechanism. The end-face lapping apparatus has a relative position shift device for shifting the relative position of the lapping board and the fixing jig board. The rod member W is lapped at a different portion of the lapping member each time the relative position shift device shifts the relative position of the lapping board.

摘要： A method of polishing an end surface of an optical fiber comprises tilting the central axis of a ferrule integrated with an optical fiber at a preselected angle .THETA. to the axis of rotation of a flat polishing member. A foremost end of the ferrule is then moved into contact with a flat polishing member to polish the foremost end of the ferrule and an end surface of the optical fiber. The foremost end of the ferrule is moved out of contact with the flat polishing member after the ferrule and the optical fiber have been polished into a flat plane. The central axis of the ferrule is then tilted at the angle .THETA. to the axis of rotation of a platen and at an angle .theta.=.THETA.+.DELTA. to a line normal to the surface of the platen, where .DELTA. is an angle of tilt of the rotational platen relative to a flat support surface supporting the rotational platen. Thereafter, the foremost end of the ferrule is moved into contact with a second polishing machine to polish the ferrule and the optical fiber. The ferrule is moved out of contact with the polishing member after the ferrule and the optical fiber have been polished into an oblique convex spherical surface so that an oblique angle defined between a plane normal to the central axis of the ferrule and a tangent plane at the intersection of the central axis of the ferrule and the surface is equal to angle .THETA..

摘要： A visual inspection apparatus is provided which is capable of obtaining an image oft a substrate at a predetermined position, in particular, a focused state of an image without using an aligning mechanism or an auto-focusing mechanism of specific use. A stage absorbs and holds a wafer. A stage-rotating mechanism rotates the stage. A first image-pickup section and a second image pickup section pick up images of the wafer with a first observational optical system and a second observational optical system respectively, and image signals are generated. An image-processing section and a deviation-amount-calculating section calculate a positional deviation amount of the second observational optical system from a position where a focus is obtained in the second image pickup section. The moving-mechanism-controlling section and the second moving mechanism control the position of the second observational optical system relative to the wafer based on the positional deviation amount.
