摘要： An object of the present invention is to provide a method of producing an Ag—ZnO electric contact material which can uniformly disperse ZnO micrograms in Ag; which maintains low contact resistance; which exhibits enhanced welding resistance and wear resistance; and which is suitable in view of production costs. The method of producing an Ag—ZnO electrical contact material comprises casting Ag and Zn at predetermined proportions and subjecting the resultant Ag—ZnO alloy to internal oxidation so as to disperse ZnO in Ag, the method being characterized in that an Ag—Zn alloy comprising 5-10 wt. % (as reduced to weight of metal) Zn, the balance being Ag, is formed into chips; the chips are subjected to internal oxidation; the internally oxidized chips are compacted to thereby form billets; the billets are pressed and sintered; and subsequently, the sintered billets are extruded, to thereby yield uniform dispersion, in Ag, of ZnO micrograms.

摘要： A base polymer is mixed with a non-polymerizable compound having a higher refractive index to form a fiber material. This material is continuously transformed into a fiber in a fiber-preparing unit. The fiber is dipped in diffusion tanks containing monomer substances so as to diffuse these substances into the fiber, and cured in a heater so as to polymerize these substances. By alternatingly repeating this procedure, the monomer substances and the non-polymerizable compound are diffused in the fiber and form a graded refractive index. Next, the fiber is drawn, coated with a cladding and coiled. This method can be performed with a high running ratio, minimizing the necessity of scaling-up of the facilities when the production is increased, and easily confers a desired index grading on the fiber. Likewise, the method allow continued manufacturing of a graded refractive index plastic optical-fiber with a desired length and of constant quality.

摘要： A preform having a core and a cladding portion is prepared for a refractive index-distributed type plastic optical fiber. The fiber obtained has a large difference in refractive index between the central and peripheral zone of the core portion. This suppresses light propagation modes in the cladding portion, a cause of deteriorated transmission characteristics, without raising the concentration of non-polymerizable compounds contained in the core portion. To manufacture the preform, a cylindrical vessel is prepared from a polymer, which serves as cladding portion. The inner surface of the preform is then provided with a polymer-containing layer having a refractive index lower than that of the polymer used for the core portion, so as to leave a cavity inside this vessel. This cavity is then filled with a monomer, which is subsequently polymerized while dissolving the lower-refractive index, polymer-containing layer, so as to form the core portion.

摘要： For an aperture plate to be used to form dot images of a two dimensional aperture pattern by projection through an imaging optical system in a normal direction, a pattern of markings in ideal positions is projected through an imaging optical system in the reverse direction to normal imaging operations. The image of the pattern is recorded at the position of the aperture plate, and the recorded image is used as a guide to form corrected apertures in the aperture plate. Accordingly, locational errors of the dot images in the normal direction are corrected when the corrected aperture plate is used.
