Abstract: Abstract:        An insulated gate field effect transistor is formed in one surface of a semiconductor substrate.  The surface portion of a channel has an impurity distribution of the conduction type opposite that of the substrate, and the deeper portion has an impurity distribution of the same conduction type as that of the substrate.  At least one of a source and a drain is formed of an impurity layer of the conduction type opposite that of the substrate with its impurity distribution gently sloped by double diffusion processes.  The result is to depress the undesirable short-channel effect experienced by prior transistor constructions and to raise the breakdown voltage.

Abstract: Abstract of the Disclosure Disclosed are a method and apparatus for forming a continuous length of glass article.  A coating of glass particles is deposited on a mandrel having a thermal coef-ficient of expansion much greater than that of the glass particles.  The mandrel is allowed to cool, thereby causing it to shrink and separate from the coating.  The coating is indexed a discrete longitudinal distance along the mandrel, thereby uncovering a region of the mandrel.  Another coating of glass particles is deposited on the uncovered region of the mandrel and over a portion of the previously applied coating.  The steps or separating or freeing the coating from the mandrel, longitudinally indexing the coating with respect to the mandrel and depositing another coating are repeated.  Thus, each step of indexing longitudinally trans-iates an incremental length of a porous body from the end of the mandrel.

Abstract: Abstract A carbonaceous material is subjected to a hydrotreating process in which it is desulfurized, deasphalted and demetallized by reaction with hydrogen in a molten medium in the presence of potassium hydroxide and water.  The water is present in an amount sufficient to minimize the formation of gaseous hydrocarbonaceous products but insufficient to significantly reduce the effectiveness of potassium hydroxide as the hydrotreating agent.  The process is characterized by producing a very small amount of gaseous hydrocarbonaceous products, desulfurizing the carbonaceous feed to the extent of at least about 80%, deasphalting the feed to the extent of at least about 60%, and demetallizing the feed to the extent of at least about 90%.  In a preferred embodiment, spent potassium hydroxide is regenerated and recycled to the molten medium.

Abstract: ABSTRACT OF THE DISCLOSURE       A three-axis navigational guidance system utilizes three specially designed internal jet-type fluidic angular rate sensors which simultaneously sense the rotational rate of a guided body relative to three mutually perpendicular control axes.  Fluidic output signals from the sensors are converted to electrical signals which are used to maintain the body in a preselected attitude relative to each of the three axes.          The sensors are rendered extremely accurate by means of unique calibration mechanisms associated therewith which compensate for or correct for fabricational inaccuracies in the sensors.  The operation of the rate sensing portion of the guidance system is environmentally stabilized by a novel jet-control system which automatically maintains the Reynolds number of each sensor jet within a predetermined range to thereby substantially eliminate jet drift.

Abstract: ABSTRACT A mobile platform structure, installation and method for use in arctic waters where the dominant environmental loading threats are posed by winter ice pressures and summer ice floes. The structure includes an ice load bearing, submergible substructure and a platform superstructure of approximately equal lateral dimensions. The substructure has a height approximately equal its depth of submergence when ballasted down onto the sea floor and includes a plurality of peripherally arranged, surface access-ible spud guides. The spuds are laterally restrained by the spud guides in the top and bottom walls for transmission of lateral loads therebetween at respective vertically spaced apart fulcrum points and are vertically movable in the spud guides for penetration into high shear soils which may be overlaid by relatively low shear soils whereby the shear capacities of both soils combine with the frictional capacity of the structure/sea floor interface to provide high displacement resistance to lateral ice loads.          Provision also is made for extracting the spuds for redeployment of the structure at another arctic installation site and for fixedly but releasably securing the spuds in an elevated position within the spud guides when not in use.

Abstract: ABSTRACT An arm assembly for a disk drive having a read/write head and a servo head on the same Winchester arm assembly is described. To eliminate the possibility of crosstalk from the data head during the write mode, to the servo head, a mumetal shield is used to partially surround the servo head ferrite core and coil. The servo head is a composite structure having a non-conducting body and a thin ferrite core so that the magnetic core volume to be shielded is minimized. In addition, a conducting layer and a ferramic plate is interposed between the data and servo heads to further isolate these heads.
