Abstract: Via holes are formed in a continuous inline shadow mask production system by depositing a first conductor layer and subsequently depositing a first insulator layer over a portion of the first conductor layer. The first insulator layer is deposited in a manner to define at least one notch along its edge. The second insulator layer is then deposited on another portion of the first conductor layer in a manner whereupon the second insulator layer slightly overlaps each notch of the first insulator layer, thereby forming the one or more via holes. A conductive filler can optionally be deposited in each via hole. Lastly, a second conductive layer can be deposited over the first insulator layer, the second insulator layer and, if provided, the conductive filler.

Abstract: In a shadow mask vapor deposition system, a first conductor is vapor deposited on a substrate and an insulator is vapor deposited on the first conductor. A second conductor is then vapor deposited on at least the insulator. The insulator layer is plasma etched either before or after the vapor deposition of the second conductor to define in the insulator layer a via hole through which at least a portion of the first conductor is exposed. An electrical connection is established between the first and second conductors by way of the via hole.

Abstract: A video projection device includes a cabinet having front and rear sections and a projection tube for projecting a video image. The video projection device also includes a screen located in the front section of the cabinet. The screen has a first surface onto which the video image is projected and a second surface for displaying the video image so that it is observable by a viewer. A mirror is arranged in the cabinet for reflecting light to the first surface of the screen. The mirror is a composite laminate mirror that includes a rigid substrate and a reflective sheet laminated to the rigid substrate. The rigid substrate may be a glass substrate and the reflective sheet may be a flexible plastic sheet. The reflective sheet may have a multilayer construction that includes a metallic film. The reflective sheet may alternatively include a second substrate and at least one thin film layer deposited on the substrate.

Abstract: Apparatus for determining at least one edge of an object having a plurality of openings with respective edges. An imaging device generates an image signal of the object to represent light intensity values of a plurality of pixels, the image signal being processed to estimate a linear relationship derived from the light intensity values of a predetermined number of the pixels. A determining device determines whether the linear relationship includes at least one light intensity value corresponding to an edge.

Abstract: A thin strip or flat web of metal material is transported longitudinally in a stable manner and without contact to the working surface by providing a generally constant transverse tension to the web. Equally spaced holes are punched along the outer edges of the web and two oppositely arranged sprockets engage the holes and drive the metal strip without any contact across the width of the strip. The two sprockets are slidably engaged for concurrent rotation with each other and biased outwardly by a spring to provide the constant transverse tension as the web is driven longitudinally.

Abstract: An alignment system for aligning the print plates of a two-sided contact printing station includes expanding pin assemblies each having an expanding collet and a mandrel for engaging and aligning match drilled holes in each of the print plates. An expansion cylinder moves the mandrel into and out of engagement with the expanding collet to cause the collet to expand into engagement with the match drilled holes. The outside profile of the expanding collet forms a straight-pin diameter which corresponds to the diameter of the match drilled holes when expanded. The expanding pin assemblies may be contracted to facilitate moving the print plates apart for advancing the working material.
