Abstract: A method of producing a substrate (12) for a plasma display panel, which comprises the steps of: contacting a rib precursor composition (32) containing a first photo-setting initiator having a first absorption edge and a first photo-setting component, closely with a base (12); filling a mold (30), obtained by photo-setting of a second photo-setting component in a presence of a second photo-setting initiator having a second absorption edge whose wavelength is shorter than that corresponding to the first absorption edge of the first photo-setting initiator, with the rib precursor composition (32); irradiating the rib precursor composition (32) with light having a wavelength longer than that corresponding to the second absorption edge to set the rib precursor composition (32), thereby forming a rib (34) on the base (12); and removing the mold (30) from the resulting base (12) on which the rib (34) is formed.

Abstract: A heat shield for use in a laminator having a laminating roller includes a movable shield member. The heat shield has a retracted position in which a laminating side of the laminating roller is exposed. Additionally, the heat shield has a shielding position in which the shield member covers the laminating side of the laminating roller.

Abstract: A right-angle gluer for applying a transverse bead of an adhesive to a blank being conveyed in a machine direction orthogonal to the transverse direction of glue application. The right-angle gluer includes a coating head operable for applying the transverse adhesive bead and a pivotal mounting assembly that permits adjustment of the positioning and orientation of the coating head relative to the machine direction. The right angle gluer further includes a backup plate positioned upstream of the coating head that reduces or prevents buckling of the conveyed blanks.

Abstract: A process for forming a uniform nanoporous dielectric film on a substrate. The process includes horizontally positioning a flat substrate within a cup; depositing a liquid alkoxysilane composition onto the substrate surface; covering the cup such that the substrate is enclosed therein; spinning the covered cup and spreading the alkoxysilane composition evenly on the substrate surface; exposing the alkoxysilane composition to water vapor and base vapor to thereby form a gel; and then curing the gel. The invention also provides an apparatus for spin depositing a liquid coating onto a substrate. The apparatus has a cylindrical cup with an open top section and removable cover which closes the top. A vapor injection port extends through the center of the cover. Suitable means hold a substrate centered within the cup and spin the cup.
