Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing high-quality glass by using raw materials having high reactivity and an apparatus for melting glass therefor. SOLUTION: In the method of manufacturing glass by adding glass raw materials to a molten glass in a heated container and melting, (1) an oxidizing gas is bubbled to the molten glass and the glass raw materials, which show reductivity in the melting process, are added into the bubbling position, or (2) a dry atmosphere gas is filled in the container and the atmosphere gas is fed to the surface of molten glass liquid along the path for adding the glass raw materials, and the glass raw materials are added. The apparatus for melting glass in the method is also claimed.

Abstract: PURPOSE: To provide a substrate with a superfine particle-contg. thin film which has the absorption of the superfine particles and is free from the influence of interference colors by making the refractive index of the thin film described above and the refractive index of a transparent substrate substantially the same. CONSTITUTION: This substrate is formed by providing the surface of the transparent substrate with the superfine particle-contg. thin film dispersed with the superfine particles in a matrix. The refractive index of the superfine particle-contg. thin film and the refractive index of the transparent substrate are made substantially the same. The superfine particles include the superfine particles of metals or metal oxide, such as metal colloid and zinc oxide superfine particles. The specific surface area of the zinc oxide superfine particles preferably exceeds 60m /g if the zinc oxide superfine particles are used as the superfine particles. The reason lies in that the thin films is made translucent and the transmittance is degraded by scattering if the specific surface area of the zinc oxide superfine particles is /g. The average grain size of the superfine particles is preferably

Abstract: PROBLEM TO BE SOLVED: To provide a process for producing high-quality glass from highly reactive raw materials and a glass-melting apparatus used in the process.
SOLUTION: The process for producing glass comprises the step of charging a material for the glass to molten glass in a heated vessel to melt the material, wherein (1) an oxidizing gas is bubbled in the molten glass and a glass raw material that behaves as a reducing agent during being melted is charged into a position of the bubbling or (2) the vessel is filled with a dry ambient gas and the glass raw material is charged while the ambient gas is allowed to flow to a liquid surface of the molten glass along an charging route of the glass raw material. There is also provided a glass-melting apparatus used in the process.

Abstract: PURPOSE:To obtain a colored filter capable of showing a colorful transmittance characteristic and excellent in resistance to UV and heat by forming the filter with a transparent substrate such as colored glass and a pigment-contg. thin film formed thereon and appropfiately combining the transmittance characteristics of the substrate and thin film. CONSTITUTION:A sol of a metal alkoxide contg. a pigment is applied on a transparent colored substrate, dried and baked to form a pigment-contg. thin film. Since a colorant, which is deteriorated in molten glass may be used, a colored filter showing a colorful and desired transmittance characteristic (including novel transmittance characteristic) is obtained. The filter is not colored by scattering light with the coloring component (colored glass and pigment-contg. thin film) but colored by the selective absorption of a light component (wavelength). Namely, since the quantity of reflected light by the coloring component itself is not so large unlike an interference filter, the colored filter is hardly flared.

Abstract: PURPOSE:To obtain a coating material which gives a film on an optical member for the prevention of internal reflection with little total reflection at the interface between them and has sufficient resistance to isopropyl alcohol used for cleaning an optical member and an optical member having a film for the prevention of internal reflection. CONSTITUTION:The coating material contains fine black inorganic partition having a diameter of at most 0.1mum and a refractive index of at least 1.5, or fine nonblack inorganic particle having a diameter of at most 0.1mum and a refractive index of at least 1.5 and a black pigment. The optical member has a film for the prevention of internal reflection which contains the above black or nonblack particles and a black pigment and which has a refractive index different by at most 0.1 from that of the optical member.
