    摘要: The process according to the invention reduces the effort required to shape a glass piece. In this process a liquid glass piece is provided on a structured supporting surface of an electrically conducting base. A voltage is applied across the liquid glass piece by connecting a voltage source between a contact position on the liquid glass piece and the electrically conducting base. The apparatus for performing the process has an electrically conducting base on which the liquid glass piece is supported and a device for applying a voltage between a contact position on the liquid glass piece and the electrically conducting base.

    摘要: Disclosed is a method of and device for manufacturing a molded glass object. In the method, glass melt is made to flow from the front end portion of a nozzle; a prescribed weight of the glass melt flowing out is received by a glass melt receiving portion provided on a forming mold moved beneath the nozzle, wherein multiple forming molds are sequentially moved beneath the nozzle; the glass melt gob received is moved from the glass melt receiving portion to a hollow provided on said forming mold; and in the hollow, a molded glass object is formed while blowing gas upward through a gas outlet provided in the bottom of the hollow. The method is characterized in that the front end of said nozzle is constantly positioned outside the space vertically above said gas outlet. Methods of manufacturing press molded articles of glass and optical glass elements are described. In these method, a molded glass object manufactured by the above method is heated, softened, and press molded or precision press molded.

    摘要: A reforming process of a quartz glass crucible in which the quartz glass crucible is reformed by an arc discharge generated by electrodes positioned around a rotational axis and configured to heat an inside surface of the crucible while the crucible is rotated. The process includes arranging electrodes in an electrode structure such that neighboring electrodes are positioned at regular intervals in a ring-like configuration; forming a stable ring-like arc between the neighboring electrodes, without generating a continuous arc between electrodes facing each other across a central portion of the ring-like configuration; heating the inside surface of the crucible; and removing a foreign substance located on the inside surface of the crucible or a bubble located under the inside surface of the crucible.

    摘要: An opaque silica glass article comprising a transparent portion and an opaque portion, wherein the opaque portion has an apparent density of 1.70-2.15 g/cm3 and contains 5null104-5null106 bubbles per cm3, said bubbles having an average diameter of 10-100 nullm; and the transparent portion has an apparent density of 2.19-2.21 g/cm3 and the amount of bubbles having a diameter of at least 100 nullm in the transparent portion is not more than 1null103 per cm3. The opaque silica glass article is made by a process wherein a mold is charged with a raw material for forming the opaque portion, which is a mixture comprising a silica powder with a small amount of a silicon nitride powder, and a raw material for forming the transparent portion so that the two raw materials are located in the positions corresponding to the opaque and the transparent portions, respectively, of the silica glass article to be produced; and the raw materials are heated in vacuo to be thereby vitrified.
