Abstract:
PROBLEM TO BE SOLVED: To provide a substrate having high mechanical strength and low heat shrinkage for application of a display, other active electronic elements and a package of an optical element or the like. SOLUTION: There is provided a method for producing a laminated sheet, wherein a first viscous fluid material is supplied to a first overflow passage; the first viscous fluid material is overflowed with a controlled manner to form a first plate flow having at least one non-contact surface of fire-polished quality; a laminated flow having at least one non-contact surface of fire-polished quality is formed by combining a second material with the first plate flow; and the laminated flow is drawn out to a laminated sheet. The second material is combined with the first plate flow by one step selected from: (a) forming a second plate flow from the second material using the continuous sol-gel process; (b) arranging the second plate material in a passage of the first viscous fluid material to generate compositional variation in the specific part of the first viscous fluid material, wherein the second material is a material of nucleus formation for glass ceramics; or (c) forming a second plate flow from the second material by overflowing the second material from one side of an overflow passage with the controlled manner.

Abstract:
A laminated sheet includes a surface layer having an optical surface that is of fire-polished quality and a core layer having a higher modulus than the surface layer to increase an overall stiffness or fracture toughness of the laminated sheet.
Abstract:
A cathode ray tube (10) with an improved tubular glass neck member having a softening point in the range 640-650 DEG C, a strain point in the range of 420-425 DEG C, a coefficient of thermal expansion in the range of 94-97 x 10-7/ DEG C, and a linear x-ray absorption value of at least 100 cm-1 and a composition, as calculated in weight % on an oxide basis, consisting essentially of 46.5-49.5 % SiO(2), 1.5-2 % Al(2)O(3), 0.5-1.5 % Na(2)O, 10-12 % K(2)O, 2-3 % SrO, 1-1.8 % BaO, 32-34 % PbO, 1-1.5 % ZnO and a fining agent.
Abstract:
Described herein are methods for protecting glass. The methods include applying to at least one surface of the glass a coating composition, wherein the coating composition comprises a base soluble polymer, a volatile base, a surfactant and water. Polymer beads may be included in the coating to prevent blocking of adjacent glass articles, typically glass sheets. Advantageously, the beads may also prevent abrasion of the glass sheets.
Abstract:
The present invention is directed to a substrate product for use in the manufacture of active matrix liquid crystal display panels. The product includes a display substrate suitable for use as a display panel. The display substrate has a thickness less than or equal to 0.4mm, a composition that is substantially alkali free, and a surface smoothness that allows the direct formation of thin-film transistors thereon without a prior processing step of polishing and/or grinding. The product also includes at least one support substrate removably attached to the display substrate.
Abstract:
A glass sheet guidance system includes a guidance member (22) having a small contact area with the glass sheet (12) and being taut to provide guidance to the glass sheet. In order to provide consistent guidance, even in environments where there is a large change in temperature, the guidance member is held taut by a tension member (24). The guidance member is supported by holders (10) so that, while remaining taut, the guidance member can be moved in three dimensions so as to accommodate glass sheets having different widths (1), heights (2), and thicknesses (3). Also, there is provided a method of guiding glass sheets with the guidance system.
