20100005837 | METHOD OF MANUFACTURING AN ELONGATED GLASS BODY - A method of manufacturing an elongated glass body by elongating a glass body of columnar or cylindrical shape. The method comprises: (1) a first elongating step for obtaining an intermediate elongated body, where the glass body is softened by heating and elongated, while the diameter of the softened part is measured, so that the measured value may become equal to a first controlled diameter which is larger than the target diameter, where the diameter of the intermediate elongated body satisfies the relationship at each position thereof: (the target diameter−10 μm)<(the diameter of the intermediate elongated body)<(the target diameter+500 μm); and (2) a second elongating step for obtaining an elongated glass body having the target diameter, where the intermediate elongated body is softened by heating and elongated. | 01-14-2010 |
20100064733 | GLASS TUBE PROCESSING METHOD, APPARATUS AND GLASS TUBE - In a glass processing method according to the invention, in the case of performing chemical vapor deposition or diameter shrinkage of a substrate glass tube G by relatively moving a heating furnace | 03-18-2010 |
20100071420 | Optical Fiber Preform Fabricating Method, Optical Fiber Fabricating Method and Optical Fiber - The present invention relates to an optical fiber preform fabricating method that makes it possible to implement a reduction in iron impurities at a low cost. The optical fiber preform fabricating method comprises a glass synthesis step for forming a glass region constituting at least a part of the core area of the optical fiber. The glass synthesis step includes a deposition step of depositing glass particles containing the Al-element inside the glass pipe by means of chemical vapor deposition, and a consolidation step of obtaining a transparent glass body from the glass soot body thus obtained. In other words, the deposition step synthesizes glass particles on the inside wall of a glass pipe by feeding raw material gas, in which the content ratio (O/Al) of the O-element and Al-element is 20 or less, into the glass pipe. Furthermore, the consolidation step obtains a transparent glass body from the glass soot body by heating the glass soot body. The transparent glass body that is formed in the consolidation step constitutes part of the core region. | 03-25-2010 |
