Abstract: A substrate is robotically picked up at a station and transported to a measuring station to measure the distance to a reference. The substrate is aligned to a robot before measurement. The measured substrate is then transported to a pharmaceutical or diagnostic powder/grain deposition station where the powder/grains are controllably deposited on the substrate to predetermined thicknesses over a plurality of powder/grain collection zones. The deposited powder/grains are then measured to determine the thickness and area covered by the deposited powder/grains at each collection zone. The substrate is then transported to a lamination station and each collection zone of powder/grains is welded to a cover substrate. The system remembers which collection zones are out of specification so that they can be later selectively discarded.

Abstract: The present invention relates to a method for manufacturing a metallized luminescent screen for a CRT. At least one phosphor layer is deposited (10) on an inner surface of a faceplate panel to form the luminescent screen. The panel containing the screen is then preheated (12) to a temperature equal to, or in excess of, a minimum film-forming temperature and prewetted (14) by applying water to the screen. An aqueous filming emulsion containing a copolymer of acrylates and methacrylates with an average molecular weight of from 250,000 to 500,000 is applied (16) to the prewetted screen and dried (18) to form a film layer. Next, a layer of aluminum is deposited (20) onto the film layer, and the panel, bearing the metallized screen, is sealed to a funnel by heating the panel and the funnel through a sealing cycle. The sealing cycle(22) has a first rate of temperature increase to a first temperature and a second rate of temperature increase, less than the first rate, to a second temperature.

Abstract: The invention provides a method of bonding a glass substrate and a nonconductive substrate comprising the steps of: (a) contacting a surface of the nonconductive substrate which is coated with a field-assist bonding material with a conforming surface of the glass substrate; and (b) applying sufficient heat to the two substrates and sufficient voltage across the two substrates to bond the two substrates together.

Abstract: A tamper detection device can determine whether a housing containing a device has been tampered with either by having the housing penetrated or by an attempt to remove a cover from the housing. The tamper detection device may be a capacitor which is placed across a portion of the housing and whose capacitance changes if it is penetrated. The temper detection device may also be a flexible circuit having conductive strips thereon forming a circuit with means to cause an open circuit if the housing is penetrated or the cover removed from the housing.

Abstract: Liquid crystal mixtures of liquid crystalline esters, biphenyls and terphenyls have wide useful temperature ranges, fast response times and a small index of refraction anisotropy which can be employed in liquid crystal cells having improved viewing angles.
