Patent number: 4330932Abstract: A controlled environment process for making diode arrays by depositing the sublimate of a semiconductor material through an aperture of a mask placed nearby a substrate and then subjecting part of the sublimate to ion implantation. The aperture causes diffraction of the sublimate vapor stream while the proximity of the edges of the aperture to the substrate causes the central plateau of the deposited thin-film to have a rounded rim leading to sides that taper smoothly in thickness to the substrate. Ion implantation to a controlled depth creates an isolated planar junction. Surface layers of a gold electrode running onto the substrate from different surface areas of the thin-film provide for off-mesa bonding of electrical leads.Type: GrantFiled: May 14, 1980Date of Patent: May 25, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventors: Hayden Morris, Richard F.

Patent number: 4327885Abstract: Invention is an aerial vehicle that uses a centrally located aft burning id-propellant motor to supply a fuel-rich exhaust to four cylindrical engines which are mounted in equally spaced relation about the exterior of the vehicle body. The fuel-rich exhaust is mixed with air in the engines and burned to provide ramjet action to propel the vehicle. A tandem booster rocket initially propels the vehicle to supersonic speed. Tail fins are interdigitated with respect to the engines and include sections which are movable upon command for steering the vehicle. Among the advantages for the vehicle are its maneuverability and its adaptability to existing missile systems.Type: GrantFiled: October 6, 1971Date of Patent: May 4, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ralph W.

Patent number: 4328554Abstract: A programmable frequency synthesizer (PFS) consists of three serially conted stages: an accumulator, a triangle converter, and a sine shaper. The accumulator is the frequency-generating stage of the synthesizer. It consists of an input latch to store the binary programmed frequency, an adder, an output latch to store the output of the adder, and a clock oscillator. The output frequency of the accumulator can be directly scaled by changing its clocking frequency. The square wave output of the accumulator is divided in frequency by the triangle converter, which produces a triangularly shaped staircase waveform. The sine shaper stage employs diode limiters and filters to produce low-harmonic sinusoids from the triangular staircase.Type: GrantFiled: July 3, 1980Date of Patent: May 4, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventor: Joseph L.
