Abstract: In a reflector (10) including a mirror base member (11) having a concave surface, a reflecting film (12) is formed on the concave surface. For preventing the fragments of the broken lamp from flying forward, a protective glass plate (13) is attached to the mirror base member. At least one of the mirror base member and the protective glass plate is made of a glass member whose mechanical strength is enhanced. The mechanical strength of the glass member may be enhanced by ion exchange.

Abstract: A glass article comprising a glass body having a surface and a water-soluble surface-protection film formed on the surface. The water-soluble surface-protection film is made of hydroxy acid or salt thereof. The hydroxy acid or the salt thereof is one or more kinds selected from the group consisting of citric acid, tartaric acid, malic acid, gluconic acid and salts thereof. An example of the glass body is a funnel part having an anode button for a CRT.

Abstract: Boric acid is used as a surface-protection coating for protecting a desired surface area of a glass article from weathering, contamination by dirt, dust, moisture and others, and streaks and/or cracks due to collision and friction with other objects. The boric acid coating is readily washed out by water upon actual use of the glass article.

Abstract: In a cathode ray tube us a glass panel having a difference in thickness between a central region and a peripheral region of a face portion, the glass panel having an outer surface with a colored film formed thereon, the colored film being thin in film thickness in an area corresponding to a thick part of the face portion of the glass panel and thick in film thickness in an area corresponding to a thin part of the face portion of the glass panel so as to reduce the difference in transmittance resulting from the difference in thickness between the central region and the peripheral region of the face portion of the glass panel. As another embodiment, the colored film comprises a film having a light color tone in an area corresponding to a thick part of the face portion of the glass panel and a dark color tone in an area corresponding to a thin part of the face portion of the glass panel.

Abstract: A method for manufacturing silicone lenses by use of a mold of specific structure is provided. The mold comprises a male section and a female section each of which has a mold surface plated with chromium, hard chromium or nickel. Both sections when joined together come into line contact with each other to define a mold cavity therebetween. With this type of mold, the method of the present invention is carried out in such a manner that a silicone resin material is cast into the mold cavity and the mold is heated in hot water until the material is cured. The cured material makes itself a finished contact lens of excellent quality.

Abstract: A mold for manufacturing silicone contact lenses is provided. The mold comprises a male section and a female section plated with chromium or nickel which when joined together come into contact with each other only at a portion at which the mold surface of one section becomes continuous with that of the other section to define a cavity therebetween. The contact between both sections is not in a flat-to-flat fashion but in a line or edge-to-edge fashion so that a contact lens whose surface and edge are completely freed from flashes or irregularities can be obtained. Further, with the use of chromium or nickel plated mold of the present invention, a contact lens of excellent quality can be obtained from a silicone resin which is affinitive to chromium and nickel.
