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 method of determining parameters of plurality of thermal cycles to achieve a set glass strain level includes providing a plurality of input parameters for a glass substrate and a plurality of parameters for a plurality of thermal cycles. The method also includes iteratively modifying at least one of the pluralities of thermal cycle parameters so the glass strain is not greater than the set glass strain level after a final thermal cycle is completed. An aspect of the method usefully enables a user to determine from the material parameters and processing sequences of the glass manufacturer and further entities that may further process the glass (e.g., the glass manufacturer's customers) whether a particular glass strain can be achieved; and if not the example embodiments allows the manufacturer to calculate changes in the customers' processes to meet the desired glass strain.
