Abstract: Abstract:   Superconducting electrodes are formed on a semi-conductor which serves as a channel.  A control electrode is disposed trough an insulator film or a p-n junction on the opposite side of the semiconductor to the semiconductor side formed with the superconducting electrode.  A super-conducting current to flow between the superconducting electrodes across the semiconductor is controlled by an electric signal which is applied to the control electrode, thereby to enhance the current gain.

Abstract: ABSTRACT OF THE DISCLOSURE:            A method and apparatus for imaging objects utilizing acoustic waves at frequencies above 4.2 Ghz and up to 8 Ghz wherein the transducer and the object imaged by waves  or beams  from the  transducer  are both at a temperature  no  greater  0.2°k.   The  transducer  is driven by pulses generated by a short pulse generator which are stretched and coded by a dispersive filter and inductively coupled to a low temperature coupler to be use  to drive the transducer.   The  frequency returns are carried by the same bidirectional coupler to  a  low  noise  amplifier.   Both  the  low  noise amplifier and bidirectional coupler are maintained at a temperature of less than 4.2°k.  The output of the amplifier is then coupled to a dispersive filter which responds the coding in the first dispersive filter to decode  the  information and reconstruct the  signal. Subsurface defects are detected by heating the object while it is inspected by the acoustic transducer.

Abstract: ABSTRACT       An improved performance memory bus architecture comprising a standard unified bus, microprocessor system, and separate memory bus.  Access to memory banks coupled to the memory bus may be made by subsystems communicating over the unified bus using the standard protocol of the unified bus, or may be made by the microprocessor using an improved access protocol method wherein an accessed memory bank generates an acknowledgement signal upon receipt of a READ or WRITE command rather than after the completion of the respective READ or WRITE operation.  A further improvement comprises an Early READ/WRITE circuit that rapidly detects the initiation of a READ or WRITE command by the microprocessor by decoding standard microprocessor status signals in order to generally commence a READ or WRITE operation prior to the time that a normal READ or WRITE operation would be commenced under the prior art.

Abstract: Abstract:    A wave shaping circuit includes a digital sampling circuit for sampling an input signal and producing a digital signal.  The sampled signal is detected by a sign detector for detecting whether it is positive or negative.  A unit difference generator is provided for generating a unit difference equal to a difference increased, during one sampling cycle, in a positive or negative direction, as detected by the sign detector.  A register is provided for storing a summed difference obtained in the previous sampling cycle.  The summed difference is multiplied by a predetermined coefficient, which is between 0 and 1, so that the product changes exponentially.  A first adder is provided for adding the summed difference multiplied by the coefficient with the unit difference.  The added result is stored in the register. A second adder is provided for adding the sampled input signal with the summed signal stored in the register, and producing a corrected signal.  The arrangement enables signal correction to substantially eliminate an unwanted DC component.

Abstract: REDUCTION OF NITROGEN-BASED POLLUTANTS    THROUGH THE USE OF UREA SOLUTIONS CONTAINING OXYGENATED HYDROCARBON SOLVENTS                      ABSTRACT    Disclosed  is  a  process  for  maintaining  low effluent  ammonia contents while reducing nitrogen oxides  in  an  effluent  from the combustion of a carbonaceous fuel under oxygen-rich conditions which minimize the production of carbon-based pollutants. An  aqueous  solution  of  urea  and  an  oxygenated hydrocarbon  is injected into an  effluent  at  a temperature  above  1600°F,  and  preferably  above 2000°F.  The oxygenated hydrocarbon will be employed at a level effective to reduce the levels of free ammonia  in the effluent.   This is important when burning fuels containing significant sulfur contents because the free ammonia tends to react with the sulfur compounds to produce solid ammonium sulfate and/or   bisulfate   which   can   decrease   boiler efficiency.
