Abstract: An ion beam deposition process for selective area deposition on a polarized substrate uses a potential applied to the substrate which allows the ionized particles to reach into selected areas for film deposition. Areas of the substrate to be left uncoated are held at a potential that repells the ionized particles.

Abstract: The invention pertains to the production of ceramic substrates used in the manufacture of thin-film photovoltaic cells used for directly converting solar energy to electrical energy. Elongated ribbon-like sheets of substrate precursor containing a mixture of ceramic particulates, a binder, and a plasticizer are formed and then while green provided with a mechanically textured surface region used for supporting the thin film semiconductor of the photovoltaic cell when the sheets of the substrate precursor are subsequently cut into substrate-sized shapes and then sintered. The textured surface pattern on the substrate provides enhanced light trapping and collection for substantially increasing the, solar energy conversion efficiency of thin-film photovoltaic cells.

Abstract: A system for reducing the shock and vibration transmitted to a missile dug transportation, stowage or launch. Rings of segmented shock-absorbing pads are disposed along the launch tube in the annular space between the missile and the tube. These pad segments are unitized by a circumferential tensile fiber hoop connecting the pad segments, and portions of this unitizing hoop are used to form control loops between these pad segments. The loop characteristics may be selectively varied to control the effective modulus and circumferential length of each unitizing hoop thus varying the force/deflection characteristics of the pad ring.

Abstract: A launching structure comprising a ram driven by a piston in a cylinder. A yrotechnic charge initiates a gas expansion underneath the piston and the expanding gases drive the ram. The ram has a helical groove engaged by a cam pin in the cylinder wall to impart a rotary motion to the ram as it is displaced linearly in the cylinder. A mass is engaged by the ram and is ejected from the cylinder with both a linear and rotational velocity.

Abstract: A modular improved forward section and improved aft section containing an tive-control package are disclosed which can be retrofitted to existing sphere-cone geometry reentry bodies (RBs) and which will provide improved aerodynamic performance and deployment accuracy of the RBs independent of missile error sources and drop sequence. An aft section containing control electronics, a propulsion system and steering jets permits the improve RB to actively correct for attitude and velocity dispersions occurring throughout the flight profile.

Abstract: A thermoelectric apparatus for adjusting the shape or position of a mirror y application of pressure from a device which changes dimensionally with changes in temperature. The device is a metallic or non-metallic generally tubular member having a heat pump mounted thereon which in turn has a thermal connection to a controllable heat source. A temperature sensor is also mounted on the device and both the temperature sensor and the heat pump are electrically connected to a controller.

Abstract: A socket wire connector for effecting a high-voltage, gas-tight joint betn an electrical wire and the connector. The socket side of the connector has a hemispherical portion soldered to one side of an electrical breadboard with a tapered, slotted cylindrical piece extending through the breadboard. An electrical wire may be inserted in the socket portion and the cap nut portion of the connector screwed onto the cylindrical piece to form a high-voltage gas-tight joint.

Abstract: A device is described using at least one polyconductor film as an active ment lens of an electrical circuit for detecting incident laser radiation. In several alternative embodiments, a polyconductor film is located at the focal point of at least one lens which focuses the incident laser radiation on the film. The polyconducting film acts as a variable resistor of a balanced bridge network and upon receipt of radiation causes an imbalance in the bridge for radiation detection. The film changes phase with increasing incident power such that it protects itself against high levels of radiation. The lenses can also be polyconducting films and another film shielded from the radiation may be included to compensate for temperature fluctuations and maintain circuit sensitivity.

Abstract: A novel technique for fabrication of a new class of surface acoustic wave (SAW) signal processing devices. Substrates of non-piezoelectric silicon or weakly piezoelectric gallium arsenide are prepared and a thin film of a piezoelectric material, such as zinc oxide, is deposited on the substrate. Interdigital transducers are fabricated at each end of the device to inject/receive SAW signals. A row of P-N diodes is constructed in the substrate underneath the SAW beam path and a metal electrode is deposited on top of the zinc oxide film. The diodes may be serially addressed/controlled by a variety of devices external to the SAW beam path, but fabricated on the same substrate and the new device used to provide transformation between high-frequency signals and low-frequency signals having the same time-bandwidth product.

Abstract: An apparatus and method by which a high-power laser beam and a high-energy article beam may enter or exit a region, typically filled with gas, to or from another region, typically under vacuum. The two beams are spaced about 3-4 mm apart center-to-center at the entry/exit point and no gas is permitted to leak into the vacuum region. A disc of material capable of resisting high radiation fluxes without forming color centers is sealed into a metallic holding block. Prior to sealing of the disc, a hole approximately 0.16 cm is drilled into the disc while the disc is tilted at or above Brewster's angle forming an elliptical hole. A thin film, approximately 6000 .ANG., indium metallization is sputtered in a circular pattern about the hole and around the edges of a beryllium disc. An indium disc is then sandwiched between the disc with the hole and the beryllium disc touching the indium metallization on each piece.

Abstract: The launch mode for a cruise missile utilizes a solid propellant booster ket to propel the missile from the launch platform to a speed and altitude sufficient to enable the missile to transition to the cruise flight mode. Immediately following booster burnout the missile jettisons the booster and transitions to cruise flight by deploying aerodynamic lifting surfaces and starting its cruise engine. The shaped trajectory launch mode significantly reduces the required booster motor impulse by deploying the cruise missile wings during boost flight. The aerodynamic wing lift enables the missile to fly a flatter trajectory reducing performance lost in climb and results in higher booster burnout velocity and significant improvement in launch performance.

Abstract: An optical alignment sensor capable of receiving radiation from a collima light source and subsequently providing orientation attitude and alignment data. Collimated light from the source impinges an aperture plate causing a shadow of the aperture plate pattern to fall across a two-dimensional photodetector array. Since the aperture pattern is larger than the active area of the array, only a portion of the light spots forming the aperture plate pattern will fall on the array. By varying the spacing of the apertures in the aperture plate in a known way, the light spots on the array can be associated with specific apertures in the aperture plate. From the location of specific light spots on the array, the angular orientation of the alignment sensor may be determined with respect to the incident beam.
