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 fluid encapsulated MEMS optical switch includes an optical waveguide matrix with MEMS mirrors situated in trenches located at waveguide cross-points. The trenches are filled with collimation-maintaining fluid and the mirrors are immersed the rein. The collimation maintaining fluid prevents the light beam from spreading when it enters the switch cross-points. This feature enables the use of much smaller MEMS mirrors and prevents some of the typical MEMS mirror problems found in the related art

A fluid encapsulated MEMS optical switch includes an optical waveguide matrix with MEMS mirrors situated in trenches located at waveguide cross-points. The trenches are filled with collimation-maintaining fluid and the mirrors are immersed therein. The collimation maintaining fluid prevents the light beam from spreading when it enters the switch cross-points. This feature enables the use of much smaller MEMS mirrors and prevents some of the typical MEMS mirror problems found in the related art. In particular, the MEMS mirror disclosed in the present invention is reduced to approximately 15 mum wide and 2 mum thick, resulting in shorter actuation distances of approximately 15 mum. This feature results in an optical switch having faster switching times.

A fluid encapsulated MEMS optical switch includes an optical waveguide matri x with MEMS mirrors (22) situated in trenches located at waveguide cross-point s (29). The trenches are filled with collimation-maintaining fluid (30) and th e mirrors (22) are immersed therein. The collimation maintaining fluid (30) prevents the light beam from spreading when it enters the switch cross-point s. This feature enables the use of much smaller MEMS mirrors (22) and prevents some of the typical MEMS mirror (22) problems found in the related art. In particular, the MEMS mirrors (22) disclosed in the present invention is reduced to approximately 15 wide and 2 thick, resulting in shorter actuation distances to approximately 15. This feature results in an optical switch having faster switching times.
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:
The invention is directed to glass articles having improved resistance to edge fracture resulting from armoring the edges using metallic material adhesively bonded to the edges of the glass article. In one embodiment the metallic edge material is machinable to enable final finish of the part to specification tolerances. One of a plurality of layers of the metallic material can be adhesively applied to edge. The glass articles have a selected length, selected width and selected thickness, and the metallic/adhesive edge protecting composite is applied to less than or equal to the thickness of the glass such that the protecting composite does not contact the surfaces of the glass.

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.
