Title: High speed cmos comparator with hysteresis
Inventor: MEADOWS WILLIAM H
IPC: G01R19/165
Filed: 1989-06-07
Granted: 1993-03-30
Abstract: Abstract HIGH SPEED CMOS COMPARATOR WITH HYSTERESIS      A comparator circuit in accordance with the present invention includes a first stage which is a standard CMOS implementation of a differential amplifier.  The differential outputs of the first stage are applied to the inputs of a second differential amplifier stage which is of the same design as the first stage.  A hysteresis element is added to the current mirror load of the second stage and is driven by an output of the second stage.  This second stage output is applied to a threshold matching single-ended gain stage.  The output of the gain stage is applied to a standard CMOS inverter which provides the final comparator output.  The hysteresis element is placed internally within the second stage to be driven by the second stage output such that the voltage difference between the differential inputs to the second stage must exceed a preselected threshold voltage before the output to the single-ended gain stage switches state.

Abstract: IMPROVEMENTS IN THE FORMATION OF               MELT-SPUN ACRYLIC FIBERS          POSSESSING A HIGHLY UNIFORM INTERNAL STRUCTURE WHICH        ARE PARTICULARLY SUITED FOR THERMAL        CONVERSION TO QUALITY CARBON FIBERS     Abstract of the Disclosure An acrylic multifilamentary material possessing an internal structure which is particularly suited for thermal conversion to high strength carbon fibers is formed via a specifically defined combination of processing conditions.  The acrylic polymer while in substantially homogeneous admixture with appropriate concentrations (as defined) of acetonitrile and water is melt extruded and is drawn at a relatively low draw ratio which is substantially less than the maximum draw ratio achievable.  This fibrous material which is capable of readily undergoing drawing is passed through a heat treatment zone wherein the evolution of residual acetonitrile and water takes place.  The resulting fibrous material following such heat treatment is subjected to additional drawing to accomplish further orientation and internal structure modification and to produce a fibrous material of the appropriate denier for carbon fiber production.  One accordingly is provided a reliable route to form a fibrous acrylic precursor for carbon fiber production without the necessity to employ the solution-spinning routes commonly utilized in the prior art for precursor formation.  One can now eliminate the utilization and handling of large amounts of solvent as has heretofore been necessary when forming an acrylic carbon fiber precursor.  Also, acrylic fiber precursors possessing a wide variety of cross-sectional configurations and a highly uniform internal structure now are made possible which can be thermally converted into carbon fibers of a similar cross-sectional configuration which are substantially void free when examined in cross section at a magnification of 2,000X.

Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.
