Abstract: A chemical vapor deposition (CVD) reactor system comprising a substantially vertical reactor tube (14) having a gas inlet (22) and a gas outlet (28), a pedestal (40) mounted within the reactor tube (14) having means (46, 54, 56) for securing a substrate (50) thereto so that a surface of the substrate (50) is exposed downward, and means for providing a gas mixture (24) to the reactor tube (14), the gas mixture (24) being introduced into the reactor tube (14) via the gas inlet (22) and subsequently withdrawn via the gas outlet (28), the gas inlet (22) and outlet (24) being positioned, with respect to the substrate (50), below and above, respectively. The gas mixture (24) is maintained in substantially uniform plug flow as it is directed into close proximity to the exposed surface of the substrate (50). This permits the CVD growth of physically uniform layers, both in terms of thickness and composition, having low contamination concentrations over large substrate surface areas.

Abstract: A metal-organic transport compound that permits the growth of readily reproducible tin doped or alloyed epitaxial layers. In a MOCVD reactor system, a process is performed involving the epitaxial deposition of a layer of a semiconductor material, including a given elemental species, onto a semiconductor substrate maintained within the MOCVD reactor chamber. The element species is obtained from the decomposition of a vapor-phase organo-metallic compound consisting essentially of tetramethyltin.

Abstract: A transverse electromagnetic mode hybrid coupler (10) for coaxial lines is formed within a metal plate (12) by milling out channels (16) of square cross-section. The walls of the channels serve as outer conductors; inner conductors (18, 19) of square cross-section are positioned within the channels. A diagonally disposed separator (34) includes a window and crosses the intersection of the coupler ports (21, 22, 23 and 24). The central conductors of the respective coaxial lines are joined by diagonally disposed segments of inner conductor such that each pair of coaxial lines is so joined. Each pair of lines provides a pair of ports. The line segments are spaced apart by a spring-loaded separator for rigidly maintaining a coupling distance. This design provides improved impedance matching and reliable coupling in both amplitude and phase over a wide spectral band.

Abstract: The resolution is enhanced first by effectively decreasing the scan angle subtended between adjacent samples significantly below that of the Rayleigh limit to obtain an image blurred by the point spread function (or diffraction pattern) of the aperture. The next step is to process this blurred image at least to partially remove the blur. The unblurring process consists of correlating each small segment of the blurred image with blurred images of preconstructed image primitives and then synthesizing a new image comprising a mosaic of spatially correlated original (unblurred ) primitives. The blurred images of the primitives are obtained from a complete set of image primitives comprising, ideally, all possible unblurred primitive shapes. These primitives are then blurred by convolution with the point spread function of the aperture of the imager.

Abstract: A bias network (44) having at least two or more selectable bias levels is used to drive a negative conductance semiconductor device (18) in a pulse mode. When a first bias level is selected (40), the semiconductor device (18) dissipates substantially all of the energy provided to it as heat. When a second bias level is selected (42), the semiconductor device (18) radiates a portion of the energy provided to it as electromagnetic energy (20), generally of microwave frequencies. Appropriate selection of bias levels allows the device to be either thermally conditioned directly or operated as a microwave frequency electromagnetic energy source. The selection of bias levels may be dynamically altered so as to change pulse rate frequency, pulse duration, and the degree of thermal conditioning with respect to each pulse.

Abstract: A laser system for providing a rapidly steerable laser output beam. The laser system includes a phase conjugate reflector (21), laser gain medium (22) and its associated pump source (23), an output coupling device (24), and an optical element (25) which selectably controls the transverse lasing mode of the laser system. The components are arranged to form a laser oscillator between the phase conjugate reflector and the optical device, and is operated in such a manner that each selected transverse mode of laser operation generates an output beam from the system which has a different wavefront tilt. Accordingly, the output beam is steerable and is dependent upon the selected transverse mode which is currently lasing in the oscillator.

Abstract: Improved laser power supply designed to provide the high electric field required for starting a laser. This invention has the capability of automatically readjusting after laser action is initiated to provide an optimum impedance match for high efficiency energy transfer. As shown in (Fig. 1), the invention includes variable means (21) for matching the impedance of a laser cavity (14) with a source of RF energy (12). In addition, means (16) are provided for sensing a change in the impedance of the laser cavity. The additional circuitry (32-46) utilizes the sensed change to vary the impedance of the matching elements (50 & 52) to provide and maintain an optimal coupling between the laser cavity (14) and the RF source (12).

Abstract: A command guidance weapon system (11) comprising a radar target tracking system (15), and a weapon (16) with small thrusters (41-46) mounted on the periphery thereof and such weapon (16) having a small beacon transmitter which is tracked by a ground-based angle measurement device (13). A rapid terminal manoeuvre is executed by the weapon at an appropriate point (31) in the trajectory of the weapon (16) by sequentially firing the small thrusters. The angular orientation of the weapon (16) is obtained by canting a polarized antenna (25), located on the rear of the weapon (16), with respect to the longitudinal axis (60) of the weapon (16) so that the signal transmitted from the weapon (16) to the ground-based fire control system (11) is modulated. The fire control system (11) computes the precise time, based upon the angular orientation of the weapon (16) and the distance between the weapon (16) and the target (20, 21, 22), to initiate the terminal manoeuvre by the weapon (16), and sends a command signal to the weapon (16).
