Abstract: Apparatus and method for deploying a spacecraft into orbit from a launching vehicle. The apparatus includes a pivot support assembly (12) having a pivot seat member contacting the spacecraft on the opposite side of its center of mass relative to the application of an ejecting force. The pivot seat member is biased against the stop member with a directional force which is less than the maximum force capable of being exerted on the seat member during the takeoff of the launching vehicle from earth but greater than the force exerted on the seat member during deployment. The biasing member can be a form of spring such as a torsion bar.

Abstract: This regulating system for an array of solar panels or the like consists of a tap connection into the array, and a boost switching regulator connected to the tapped array. The tap connection divides the array into first and second portions, and the switching regulator is connected so that its power-input terminals are across only one of the two portions of the array. The power-output terminals of the switching regulator are connected across the load (i.e., across the entire array), and the sensing or feedback terminals of the regulator receive a signal which acts as a measure of voltage or current at the load. Boost regulators do not dump overvoltage into a dissipative load; hence the invention prevents local heat generation and resulting spacecraft heat-balance problems of conventional dissipative regulators. Furthermore, in the circuit of the present invention, negligible power flows through the regulator at the end of the solar-panel useful life; hence efficiency losses in the boost regulator itself are avoided when power is at its greatest premium.

Abstract: An improved process for depositing an oxide layer on a substrate by exposing the substrate to a selected vapor phase reactant and an oxygen-containing precursor comprising nitrous oxide mixed with molecular oxygen in a predetermined ratio, in the presence of radiation of a selected wavelength. The radiation causes the direct dissociation of the oxygen-containing precursor to form neutral oxygen atoms that react with the vapor phase reactant and form the oxide, which deposits as a layer on the substrate. The rate of reaction to form and deposit the oxide layer is enhanced by the mixing of molecular oxygen with nitrous oxide in the precursor.

Abstract: A transverse discharge excitation laser which includes a dielectric structure (11, 13, 111, 113, 211, 213) for defining an elongated laser excitation cavity (27, 127, 231) suitable for containing a laser gas and maintaining a laser exciting discharge in the laser gas, and further includes opposing conductive electrodes (33, 41, 129, 133, 237, 245) adjacent the laser cavity. The electrodes are sufficiently small to produce a laser exciting discharge within a predetermined region of the laser cavity and to provide optimum efficiency for the desired mode of operation. The electrodes are particularly adjacent opposing walls of the cavity which have a width W, and at least one of the electrodes has a width which is less than the wall width W.

Abstract: A spectral analyzer and direction indicator system (10) includes optical channels (20, 30, 40) for providing detected optical information indicative of incidence direction and spectral content of incident radiation. Each optical channel includes a reflector element (11, 17, 23) having a non-ruled section (11a, 17a, 23a) and a spectrally dispersing ruled section (11b, 17b, 23b); an analytical optical system (13, 19, 25); and a detector array (15, 21, 27). For each reflector element the non-ruled section is tilted in one or two directions relative to the ruled section. The disclosed spectral analyzer and direction indicator system is advantageously utilized as an aircraft based sensor in an aircraft landing system having ground based lasers (29L, 29R, 33L, 33R, 37L, 37R) directed into the landing approach path.

Abstract: A photolithographic process useful for VLSI fabrication for achieving side-wall profile control of poly lines, metal lines, contact and via openings. Layers (20, 25) of a first and second photoresist materials are formed on the poly, metal or oxide-covered substrate (10, 15). The top layer (25) is patterned by conventional processes to define the final device geometry. The bottom layer (20) is exposed and overdeveloped to form an overhang structure about the line pattern or the contact/via opening (30). During the subsequent anisotropic plasma-assisted etching step, some ions or particles are passed obliquely over the overhang and bombard the opening corner, the side-wall and the under-cut area. The plasma-assisted etching step not only forms the poly or metal lines, or the contact or via opening (30), but a smoothly tapered side-wall profile. The subsequent metal film (40) deposition step results in a uniform film thickness around the edges of the opening. The process thus alleviates the problem of high contact resistance previously encountered as a result of dry etching the contact or via openings.

Abstract: A plurality of heat pipes extend longitudinally through a unitary or segmented circuit card module, terminating at both ends in cavities formed along lateral edges of the module. In one embodiment, bellows extend outwardly from the cavities in a direction normal to the plane of the module, terminating in interface plates which extends along the respective lateral edges of the module. In another embodiment, upstanding pillars are connected to bellows covering the cavities. Electronic components are mounted on a circuit card applied to a face of the module. The module is loosely received between opposed liquid cooled surfaces of guiderails in a circuit card rack. Heat from the components is communicated through the card to the heat pipes, increasing the pressure within the pipes to urge the interface plates or pillars into variable pressure contact with the guiderails. The pressure is sufficient to snugly hold the module in the rack. The thermal resistance between the interface plates or pillars and the guiderails varies as a function of the contact pressure, providing fast warm-up and lower operating temperatures for the components.

Abstract: Light sensitive recording medium is exposed to highly absorbed incoherent light either before or after a slant fringe hologram is recorded therein to reduce the sensitivity of the medium at surface regions adjacent a supporting substrate. The fringes recorded in the area of reduced sensitivity have lower contrast than those recorded in the remainder of the medium, freeing the fringes from the substrate and allowing greater expansion of the medium during a subsequent chemical swelling process. The increased swelling amplifies the refractive index modulation in the medium to increase the diffraction efficiency of the hologram. Dye may be added to the medium to increase absorbance of the incoherent light.
