    摘要: The optical fiber fixing member made of glass, especially optical fiber guide block, is conventionally produced by a mechanical processing. However, the mechanical processing has problems that a production cost becomes high and mass-production is difficult. The problems above can be solved by the present invention providing a method for producing an optical fiber fixing member comprising: disposing a glass shaping preform whose plane view resembles to the plane view of the molded article and whose faces to be positioned in the pressurizing direction during press-molding assumes planes or outwardly convex curved surfaces, in a mold having a cavity of a given shape; and heating the glass shaping preform up to a temperature at which the glass shaping preform can be mold-shaping and thereby press-molding it into a molded article having at least one edge formed of a free surface.

    摘要: The present invention relates to a mold for producing glass articles comprising a glass-made mold base, an intermediate layer formed by a silicon carbide and/or silicon nitride film, and an uppermost layer formed by a carbon film. Since the mold for producing glass articles exhibits an excellent bonding between the glass-made mold base and the uppermost layer formed by the carbon film, peeling of the uppermost layer can be prevented. Therefore, the function of the uppermost layer as an adhesion-prevention layer against the glass to be molded can be exhibited for a long time, causing an economic advantage since the life of the mold can be lengthened. In addition, since the maximum surface roughness of the working surface of the mold can be reduced and the surface shape accuracy can be maintained, a molded glass article exhibits excellent surface accuracy without optical defects.

    摘要: According to a method of molding a glass body, a glass preform is placed between upper and lower molds of a mold assembly. The mold assembly is then heated to a predetermined heating temperature falling within a heating temperature range corresponding to a glass viscosity range of the glass preform of 10.sup.8 to 10.sup.10.5 poise. A pressure high enough to mold the glass preform is applied between the upper and lower molds when the glass preform is at the predetermined heating temperature, so that an unfinished glass molded body is formed. The pressure is released, and the unfinished glass molded body and the mold assembly are gradually cooled to a temperature within a glass viscosity range of 10.sup.11.5 to 10.sup.14 poise while the unfinished glass molded body is held in the mold assembly. A glass molded body is then released from the mold assembly.
