Abstract: A system for handling semiconductor and electronic elements secured to an adhesive surface is provided. According to one aspect of the invention, a vacuum is applied through holes in a loading base. Under the influence of the vacuum, the adhesive film is pulled down toward the loading base and stretched around a pick rod so that the adhesive film is peeled away from the element. Thus, adhesive contact between the film and the element is reduced and a vacuum pick or collet is able to lift the element from the adhesive film with minimal force applied to the surface of the element.

Abstract: An apparatus and process for retaining laser bars during a facet coating operation and releasing the bars after the conclusion of the facet coating operation. A multitude of spacers are positioned with laser bars therebetween. Each spacer includes an upper and lower fixture blade. The spacers are compressed together, thus sandwiching the laser bars, during the facet coating operation. After release of the compressive force, adhered laser bars are removed by moving one of the fixture blades relative to the other fixture blade. Movement can be along the longitudinal axis of the blades, perpendicular to the longitudinal axis, or rotation about a pivot axis. Further, movement can include elevation of one blade, or an end of one blade, relative to the other blade.

Abstract: A reflection filter is disposed on a solid state laser so as to preferentially reflect TE or TM modes and to suppress oscillation within the resonator of the non-reflected modes. In one embodiment, the filter includes a layer having a plurality of grooves which may be straight and parallel or curved to approximate the mode shape. In another embodiment, the filter includes a polarization sensitive film, without grooves, which either absorbs or transmits the undesired mode. Specifically described is a buried heterostructure semiconductor DFB laser with such a reflection filter formed on at least one facet thereof.

Abstract: Disclosed is a device including a surface coating for passivation or anti-reflection, and a method of manufacture. The coating comprises ZrO.sub.2 doped with yttrium, magnesium or calcium. The doped ZrO.sub.2 is preferably deposited on the device surface by electron-beam evaporation from a single crystal source of ZrO.sub.2 and Y.sub.2 O.sub.3, MgO or CaO.

Abstract: The disclosure is of a cathode ray tube having a face plate for displaying information and carrying an electrode assembly which is curved to adhere smoothly to the face plate. The electrode assembly includes a shield against radio frequency interference and an insulating support sheet having an inner surface and an outer surface, on each of which an array of rows and columns of conductive areas is formed. On the inner surface, the rows of conductive areas are electrically connected together to output contact pads at a side edge of the sheet, and, on the outer surface, the columns of conductive areas are electrically connected together to output contact pads along the lower edge of the sheet. Each outer conductive area overlies and is capacitively coupled to an inner conductive area. A column conductor which extends from a contact pad at an edge of the outer surface of the sheet is capacitively coupled to each column of outer conductive areas.

Abstract: The garment includes a collar portion to be worn around the neck and an auxiliary porous shield portion which is adapted to be raised in front of the face and secured along its edge to the lower edge of the visor portion of a helmet of the type worn by motorcycle riders.

Abstract: The display panel is filled with an ionizable gas and includes a base plate on which a plurality of groups of cathodes and their conductors are formed, each group of cathodes being operable to display a character. The panel also includes a face plate, spaced from the base plate, and carrying transparent conductive anodes, each associated with one group of cathodes. The base plate and face plate are hermetically sealed together by a frame of a sealing material formed from a thin layer of powdered glass in a removable carrier.The panel is made by assembling all of the parts and sealing the envelope but including a wire in the frame of sealing material. After the seal has been formed, the wire is removed to leave a small hole providing gas communication with the interior of the panel. The panel is then placed in an oven and evacuated, baked out, and filled with the desired gas filling through the hole, after which the hole is hermetically sealed.

Abstract: The apparatus of the invention comprises a cup-shaped metal ring carrying a mercury amalgam from which mercury can be released, the ring being held within a supporting mass of fibrous insulating material and the entire assembly loosely mounted in the tubulation secured to the base plate of a display panel.

Abstract: A mercury capsule comprises a mercury-filled metal tube, of measured capacity, having closed ends, each of which includes end portions which are cold welded and resistance welded to form an hermetic seal and intermediate portions, which are crimped closed. The length of the intermediate crimped portions of each capsule is designed to permit the mercury within the capsule to expand and stress the lightly crimped portions, during processing operations of a device in which a capsule is mounted, without opening the hermetically sealed end portions of each capsule.The method of the invention comprises filling a metal tube with mercury, closing the open end, and forming light crimps in the tube at spaced locations to form individual capsules, each of which is filled with a measured quantity of mercury.
