Abstract: METHOD FOR PASSIVATING A COMPOUND SEMICONDUCTOR SURFACE AND DEVICE HAVING IMPROVED SEMICONDUCTOR-INSULATOR INTERFACE                   ABSTRACT OF THE DISCLOSURE           A method for passivating the surface of a compound semiconductor comprises annealing the substrate to form an anion  rich  surface  layer containing cationic and anionic oxides and stripping the oxides to leave only a very thin anionic  layer  on  the  surface.   The  substrate  is  then subjected to an H2 plasma cleaning to remove chemisorbed oxygen. An N2 plasma cleaning is then performed to form an anionic nitride layer that is free of any cationic nitride.          A layer of insulating material, such as, a native or other oxide, or a nitride, is deposited.  The resulting structure has a very low interface state density such that the Fermi level may be swept through the entire band gap.

Granted: 1996-10-01
Abstract: Perfluorocarbon  hydrides,  either  alone  or  in combination with other perfluorocarbon compounds,  may be introduced into a non-vascular animal space as a contrast agent  in  magnetic  resonance  imaging  (MRI),  computed tomography (CT)  or conventional X-ray procedures.   In the image  generated  by  these  systems,  the  fluorocarbon introduced into the space is contrasted with the remaining body tissues  or spaces  to distinguish the  fluorocarbon-occupied space from other tissues and spaces.     Perfluoroctyl hydride vaporizes at body temperature, and  its  gas  phase,  which  also  provides  an  effective contrast  to  tissues,  is  disclosed  in  imaging  areas  of comparatively  large  void  volume  while  using  a  lower fluorocarbon  dose  then  than  required  for  fluid fluorocarbon.     Perfluorocarbon hydrides offer less radiodensity to X-ray imaging and less hydrogen density to MRI imaging, and are disclosed as diluents for perfluorocarbon bromides in applications  where  concentrated  brominated compounds  are found to cause imaging artifacts.     Perfluorocarbon  emulsions  comprising  a  mixture  of perfluorocarbon bromide and at least 0.1% perfluorocarbon hydride are disclosed for intravascular use as a contrast agent or for oxygen transport.

Granted: 1992-03-31
Abstract: ABSTRACT           Programmable logic array, multiplexer and memory array circuits utilizing the dynamic CMOS logic of the invention are capable of operating at speeds approximating twice that of similar circuits utilizing conventional dynamic CMOS logic.  The circuit of the invention has an AND plane defined by a series of input columns and a series of rows, and has an OR plane defined by the series of rows and one or more output columns.  Transistors are connected selectively between the input columns and the rows, and between the output columns and the rows.  During one state of an external clock input to the circuit each of a series of inputs are placed on a respective one of the input columns, each of the output columns are precharged, and each of the rows is discharged. The shifting of the external clock input to the alternate state results in latching of the values on the input columns and in termination of the output column precharging and row discharging. Charge is then injected into each of the rows, and propagates through both the AND and OR planes while the external clock input is still in the alternate state.  Unlike conventional two-plane dynamic CMOS logic circuits, there is no need for clocking circuitry intermediate of the two planes.

Abstract: The present invention relates to a process of forming an extended elongate product from a plurality of strands by subjecting the strands to heat and pressure. The improvement of the present invention comprises a method for compressing the strands in a manner to reduce internal stresses imparted to the product during its subjection to pressure. The method includes the steps of: (a) transporting in a longitudinal direction the strands in a generally parallel and overlapping relationship through a compressing zone of a press assembly; (b) increasing the pressure on the strands as they pass from an inlet end to an outlet end of the compressing zone by gradually converging facing walls of the press assembly so that: (i) the strands being compressed move relative to one another through at least a portion of the compressing zone; and (ii) the strands being compressed lock up so that they no longer move relative to one another but rather only compress relative to one another at a point in the compressing zone where the radius of curvature in the longitudinal direction on either side of a central reference plane of the mat being compressed is at least about 30 feet to provide a low remembered internal stress.
