Patent number: 4715940Abstract: A shadow mask is provided which can provide a precise patterning to a deposit at process temperature without destruction of the shadow mask itself. The shadow mask consists of a plurality of metallic strips having a series of interconnecting small arched bridges that hold the strips of the mask together. The shadow mask is used in a process for depositing electrode structures in an electroluminescent device wherein the mask is positioned over a substrate surface to be coated and deposit electrode material is sprayed from a geometrically broad source, through the mask and onto the substrate. Deposition occurs beneath the arched bridges resulting in a pattern deposition that does not readily reveal the presence of bridges because sufficient material is coated beneath to provide cosmetic and electrical continuity between areas separated by the bridges. This invention is particularly suited for a mask designed to provide a fine pattern of closely spaced parallel lines or electrode structures.Type: GrantFiled: October 23, 1985Date of Patent: December 29, 1987Assignee: GTE Products CorporationInventor: Robert A. Boudreau

Patent number: 4687453Abstract: A method and an apparatus for position orienting a base assembly of a metal halide lamp is describe for maintaining the curved arc tube in the upward position when the lamp is inserted in a socket. Once the lamp has been fully assembled and sealed a locator structure is attached to the base shell in order to create a base assembly which will properly position the lamp when it is in the socket. The welding apparatus of the present invention resistance welds the locator structure onto the base shell once the locator structure has been aligned approximately 90 degrees counterclockwise from the tip of the curved portion of the arc tube when viewed from the dome end of the lamp. The lamp resulting from the method and use of the apparatus will be more inexpensive and will not have the problems of a loose base or a cracked seal.Type: GrantFiled: November 28, 1986Date of Patent: August 18, 1987Assignee: GTE Products CorporationInventors: Ronald C. Lekebusch, John T. O'Neil, Jr., Martin E. Muzeroll

Patent number: 4686412Abstract: This invention provides for an improved reflector-type lamp having reduced focus loss and exhibiting an increase in reflector collection efficiency. Stray light from the lamp's light source is reduced and channeled into the central angular region of the reflector where it can be more easily controlled and increase the in candle power of the lamp. A shorter, more compact filament design, wound with larger mandrel ratios, is positioned within the reflector to evenly disperse the light energy throughout the central angular region.Type: GrantFiled: April 14, 1986Date of Patent: August 11, 1987Assignee: GTE Products CorporationInventor: Pierce Johnson, Jr.

Patent number: 4683397Abstract: This invention provides an improved compact fine wire incandescent lamp filament and method for making such having a primary mandrel ratio in the range of about 1.40 to about 4.00 and a secondary mandrel ratio which is greater than or equal to the primary mandrel ratio. The improved filament design exhibits an increase in compactness and retains or increases structural rigidity while exhibiting minimal sag when the filament is incorporated into an incandescent lamp of the tungsten halogen type variety. The compact coiling method is particularly useful in designing compact filaments for high voltage applications where it is desirable to eliminate the use of rectifying means to lower the effective voltage across the filament.Type: GrantFiled: April 14, 1986Date of Patent: July 28, 1987Assignee: GTE Products CorporationInventor: Pierce Johnson, Jr.

Patent number: 4670097Abstract: An optically transparent and electrically conductive film is patterned on a ubstrate, for instance in an electro-optical display device such as an electroluminescent device having a patterned transparent electrode layer, by a process utilizing a double masking structure that provides for more positive delineation of thin film device patterns. In this process, an indium tin oxide layer is formed between a metallic pattern on a glass substrate and a photoresist mask. The indium tin oxide layer has a metal lift-off mask under those areas that are to be removed and a photoresist protective mask over those areas that are to remain. The double masking will also provide greater protection to the electrode areas during the critical etching steps in developing an electroluminescent display.Type: GrantFiled: December 23, 1985Date of Patent: June 2, 1987Assignees: GTE Products Corporation, The United States of America as represented by the Secretary of the ArmyInventors: Mohamed I.

Patent number: 4618802Abstract: A hermetically sealed enclosure for a thin film device, such as an electroluminescent device, in which the device includes a thin film matrix supported on a glass substrate. The glass substrate is mounted in a frame and a frit seal is provided between the glass substrate and the frame. A cover is also secured and sealed to the frame by a weld or solder joint. The integrity of both the substrate to frame seal and the frame to cover seal is preserved by forming the surfaces bounding each seal out of materials having substantially similar coefficients of thermal expansion. Since the rates of expansion will be similar, the seals should not develop weaknesses throughout the life of the device over a range of temperatures.Type: GrantFiled: October 29, 1984Date of Patent: October 21, 1986Assignee: GTE Products CorporationInventor: Martin P.
