Abstract: ABSTRACT OF THE DISCLOSURE           A manufacturing method for VLSI MOS field effect transistor circuits having digital and analog functions performed by short channel transistors and analog transistors integrated on one chip.  An n-tub manufacture is performed wherein as soft as possible a field progression in front of a drain-side pn-junction of the analog transistor is achieved.  This occurs by means of an additional drain implantation (curve II) with drive-in diffusion before the actual source/drain implantation (curve I) of the n-channel transistors.  Both the additional implantation as well as the source/drain implantation are carried out with phosphorous ions.  The dosage of the additional implantation lies one to two orders of magnitude below the dosage of the actual implantation, and the penetration depth x in the additional drive-in diffusion is about twice as great as the penetration depth x of the actual source/drain regions.  The method is applied in the manufacture of VLSI CMOS circuits.

Abstract: METHOD OF GENERATING INVOLUTE TOOTH FORMS WITH A MILLING CUTTER              ABSTRACT OF THE DISCLOSURE An involute external tooth profile is cut into the periphery of a gear blank by positioning a rotating milling cutter with its cutting path perpendicular to the plane of action of the desired base surface of revolution within the gear blank so as to penetrate the plane of action from the side thereof opposite to the base surface and with a predetermined line of intersection which generates the involute profile as the base surface rolls upon the plane of action.  The rolling action causes the generating line to traverse the blank between its addendum surface and a depth sufficient to provide the desired length of active profile.

Abstract: ABSTRACT OF THE DISCLOSURE           A multiple hearth reactor and process for the thermal treatment  of  organic  carbonaceous  materials  under  controlled pressure  and  temperature  comprising  in  accordance  with one embodiment,  a  pressure  vessel  containing  a  plurality  of superimposed annular hearths including a series of upper hearths which are angularly inclined downwardly toward the periphery of the reactor defining a preheating zone and a series of lower hearths spaced therebelow defining a reaction zone.  The reactor is provided with an inlet in the upper portion thereof  for introducing a moist carbonaceous feed material under pressure into the preheat zone and the feed material is transferred by means of rabble arms in an alternating inward and outward direction across the hearths and passes downwardly in a cascading manner through the preheat  zone  and reaction  zone.   The  solid  carbonaceous upgraded reaction product is extracted from the lower portion of the reactor while waste water and product gas are extracted from the upper portion of the preheat zone.  The hot reaction gases generated  in the  reaction  zone  are passed in  countercurrent fashion relative to the feed material to effect a preheating thereof in the preheat zone and the liberation and extraction of moisture therefrom.  In accordance with a second embodiment of the apparatus,  a  separate  reactor  is  employed  for  effecting  a preheating of the feed material and the preheated and partially dewatered feed material is thereafter directly charged into the multiple hearth reactor defining the reaction zone.  In operation, the reactor is adapted to operate at temperatures ranging from about 200°F up to about 1200°F or higher at pressures generally ranging from about 300 up to about 3000 psig.  Residence times of as little as 1 minute up to about 1 hour or longer can be employed depending upon the nature of the feed material and the desired thermal restructuring of the carbonaceous feed material.

Abstract: SYSTEM FOR REPRODUCING MIXED IMAGES        Abstract An electronic processing system for reproducing mixed images, i.e., original images having areas of continuous tone and areas of text, in such a manner that both areas are of balanced, good quality in the reproduction.  The image to be reproduced is (1) divided into non-overlapping 4 x 4 blocks of pixels or picture elements, and, (2) each block is classified as either of TEXT or IMAGE, based on the values of the 16 pixels within it.  The classification is improved by (3) eliminating short runs of blocks with the same classification.  The pixel values are then adjusted by appropriately (4) thresholding those in the TEXT blocks, and, (5) averaging those in the image blocks.  The IMAGE block values are quantized to one of 17 levels using an improved error diffusing process and then mapped onto a 4 x 4 pattern preparatory to (6) merging the binary images for the TEXT and IMAGE areas.  Converting to various patterns to suit the output device such as a specific printer  is possible by permitting the conversion of the bits for an IMAGE block from one pattern table to another.

Abstract: MIXER DRIVE APPARATUS                         Abstract Mixer drive apparatus, which provides gear reduction for driving the impeller shaft of the mixer. A drive shaft from an electric motor is parallel to the impeller shaft which extends through a support collar of a housing where the collar has a hole therethrough into which the impeller shaft extends into the housing.  A hub is rotatably mounted on the outside of the housing and carries a gear which is coupled to a pinion on the motor drive shaft.  A coupling is attached to the hub and bridges the hole in the collar.  The end of the impeller shaft is cantilevered and overhung from the coupling.  A gap is defined between the impeller shaft and the inside surface of the support collar which is adapted to receive a seal assembly.  The seal assembly includes a retainer hub which captures a sleeve containing the seal structure in the gap between the coupling and the retainer.  The seal sleeve may readily be removed upon disassembly of the coupling, which has two sections defining a split ring which clamps the upper end of the impeller shaft, and has a thrust plate with a bolt therethrough into the end of the impeller shaft for axially adjusting the location of the shaft so as to bring the seal sleeve into engagement with the coupling for rotation therewith.  A support collar on the impeller shift engages the retaining hub when the coupling releases the shaft for the removal and replacement of the seal sleeve assembly.  A seal captured by the collar engages the retainer hub and provides a pressure seal to facilitate replacement of the seal sleeve when the mixer is used with a pressurized vessel.
