摘要： In a foreign matter detecting apparatus 1, light beams are applied to a moving plastic resin extruded from an extruder, and a foreign matter, if any, in the plastic resin is detected by transmitted light beams. First and second projectors 30a,30b of the foreign matter detecting apparatus apply a plurality of light beams with different convergence diameters to the plastic resin which is extruded and moves in a passage 18. First and second light receivers 40a,40b receive the light beams transmitted through the plastic resin, and compare their respective reception levels with a plurality of levels of light reception which are previously set corresponding to the size of the foreign matter. Based on the result of comparison, the light receivers detect the presence and size of the foreign matter involved in the plastic resin.

摘要： An optical fiber array includes a plurality of optical fibers which are arranged and fixed in a fiber array member. The optical fibers each have an end projecting from an end face of the fiber array member at substantially the same distance, and each have a lens formed at the end thereof. The optical fiber array is produced by arranging and fixing a plurality of optical fibers in the fiber array member such that each end of the optical fibers is projected from the end face of the fiber array member; forming a coating layer of a desired thickness over the end face of the fiber array member and portions of the optical fibers projecting from the end face of the fiber array member; collectively polishing the ends of the optical fibers projecting from the end face of the fiber array member, together with the coating layer, up to a predetermined position, thereby making the lengths of projections of the optical fibers substantially equal; and removing the coating layer and forming a lens at each end of the optical fibers.
