摘要： PROBLEM TO BE SOLVED: To eliminate or substantially reduce a general type of thickness variation identified as short wave variation.SOLUTION: An apparatus for forming a continuous ribbon of molten glass includes: a forming body comprising converging forming surfaces that converge at a root; an enclosure disposed about the forming body; a cooling unit 38 coupled to the enclosure. The cooling unit includes: a fixture 42; a pivot member 46 disposed within the fixture; and a cooling tube 40 coupled to the pivot member. The pivot member is configured to rotate about at least one axis 52, thereby causing the cooling tube to direct a cooling gas flow toward the molten glass flowing over the forming body. When the pivot member is rotated about the axis 52, a lateral position of an end of the cooling tube varies relative to the forming body.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber for decreasing optical fiber loss to the lowest level.SOLUTION: An optical fiber includes a silica-based core having a first dopant for selecting from a group comprising germania, fluorine and mixtures thereof as well as a second dopant containing an alkali metal oxide composed of KO in a peak concentration of 20-1,000 ppm. The concentration of the alkali metal oxide varies with a radius of the optical fiber. The concentration of the alkali metal oxide dopant in the core and a clad is properly selected so that the core has the refractive index profile which is the peak relative refractive index ΔMAX of more than 0.2% with the cladding.
