Patent number: 5520747Abstract: A low concentration solar array for spacecraft and other uses which has a series of solar panels which can be deployed from a folded stowed configuration to a planar configuration. When the solar panels are stowed, the padding of reflector panels cushions and protects the solar panels from the stresses and vibrations of launch and space flight. Once the solar panels are extended into a deployed planar configuration, the reflector panels are raised to concentrate sunlight upon the solar panels. These reflector panels are constructed from rigid honeycomb substrates and therefore are the active structural members of the solar array, providing the structural rigidity for the solar array.Type: GrantFiled: May 2, 1994Date of Patent: May 28, 1996Assignee: Astro Aerospace CorporationInventor: Geoffrey W.

Patent number: 5514260Abstract: The present invention relates to an apparatus for simultaneous plating with which arc ion plating and hollow cathode discharge (HCD) ion plating can be concurrently carried out in one chamber, and sputtering plating can also be performed in the other chamber while the former two types of platings are being performed.

Patent number: 5512109Abstract: Electric power generator has linear arrays of thermophotovoltaic cells spaced outwardly from a tubular IR emitter. Hot combustion products flow downward from a combustion zone between a central pillar and the IR emitter, and then upward between the emitter and a tubular IR transparent window. The cell arrays are spaced outward from a convection barrier tube and a short pass filter. A burner assembly at the top of the pillar has an alternating arrangement of accelerating air channels with large openings to the air supply and slowing mixing channels with small openings to the air supply. Radial fuel channels connect the central fuel supply with the peripheral mixing channels. Release of accelerated air creates turbulence in the combustion zone where the air and fuel further mix and are ignited. A cavity in the pillar supplies liquid fuels which are atomized by ultrasonic energy from a central rod. The atomized liquids are released through small holes into the combustion zone.Type: GrantFiled: February 24, 1995Date of Patent: April 30, 1996Assignee: JX Crystals, Inc.Inventors: Lewis M.

Patent number: 5510271Abstract: Processes which utilize rapid thermal processing (RTP) are provided for inexpensively producing high efficiency silicon solar cells. The RTP processes preserve minority carrier bulk lifetime .tau. and permit selective adjustment of the depth of the diffused regions, including emitter and back surface field (bsf), within the silicon substrate. Silicon solar cell efficiencies of 16.9% have been achieved. In a first RTP process, an RTP step is utilized to simultaneously diffuse phosphorus and aluminum into the front and back surfaces, respectively, of a silicon substrate. Moreover, an in situ controlled cooling procedure preserves the carrier bulk lifetime .tau. and permits selective adjustment of the depth of the diffused regions. In a second RTP process, both simultaneous diffusion of the phosphorus and aluminum as well as annealing of the front and back contacts are accomplished during the RTP step.Type: GrantFiled: September 9, 1994Date of Patent: April 23, 1996Assignee: Georgia Tech Research CorporationInventors: Ajeet Rohatgi, Zhizhang Chen, Parag Doshi
