Abstract: LATCHUP-PREVENTING CMOS DEVICE AND METHOD FOR FABRICATING SAME            Abstract A new CMOS device which avoids latchup while achieving a spacing between the n-channel and p-channel FETs of the device smaller than 10 µm, as well as a method for fabricating the device  is disclosed.          The inventive CMOS device includes a latchup-preventing, polysilicon-filled trench formed in the semiconductor substrate between the n- and p-channel FETs of the device.  The polysilicon-filled trench is essentially free of crack-inducing voids, and achieves a width less than 10 µm, because the angle between the trench sidewall and a perpendicular drawn to the substrate surface is greater than! or equal to, about 5 degrees but less than about 10 degrees.  Also, a thickness of the polysilicon deposited into the trench is greater than half the width of the trench.

Abstract: TITLE:  BUFFER CIRCUIT SUITABLE FOR LOW VOLTAGE OPERATION     ABSTRACT OF THE DISCLOSURE     An integrated circuit unity gain buffer ampli-fier suitable for low voltage operation, in which the in-put signal is applied to the base of a common emitter NPN transistor first stage. The collector of the first stage is  connected  to  the  base  of  an  emitter follower NPN transistor second stage.  The emitter of the second stage is  connected  to  the  base  of  an  emitter  follower  PNP transistor third stage.  The collector of the first stage is loaded by a constant current source and its emitter is connected through a resistance to ground.  The collector and emitter of the second and third stages respectively are connected together through a resistor to the supply voltage.   The emitter of the second stage is connected through a resistance to ground.   The collector of the third stage is connected both to the output terminal and to the emitter of the first stage.  This allows the cir-cuit to operate at a very low supply voltage without any transistor operating in practical saturation.

Granted: 1988-10-18
Abstract: A process for preparing a stabilized coal particle suspension which includes the steps of providing an aqueous media substantially free of coal oxidizing constituents, reducing, in a nonoxidizing atmosphere, the particle size of the coal to be suspended to a size sufficiently small to permit suspension thereof in the aqueous media and admixing the coal of reduced particle size with the aqueous media to release into the aqueous media coal stabilizing constituents indigenous to and carried by the reduced coal particles in order to form a stabilized coal particle suspension.  The coal stabilizing constituents are effective in a nonoxidizing atmosphere to maintain the coal particle suspension at essentially a neutral or alkaline pH.  The coal is ground in a nonoxidizing atmosphere such as an inert gaseous atmosphere to reduce the coal to a sufficient particle size and is admixed with an aqueous media that has been purged of oxygen and acid-forming gases.

Abstract: ABSTRACT OF THE DISCLOSURE           A modular panel system consists of a plurality of panels.  Each panel carries one or more hinges, and at least one of the hinges of the system includes first and second pin members each having parallel limbs of circular cross-section forming hinge pins, and first and second hinge plates.  Each of the hinge plates has first and second limb-receiving journals.  The arrangement is such that one hinge plate can pivot through 360° relative to the other.  The first 180° of this movement is pivoting about a first common axis defined by collinearity of two axes of pivoting, namely the axis of pivoting of the second limb of the first pin member within the first journal of the second hinge plate and the axis of pivoting of the first limb of the second pin member within the second journal of the first hinge plate.  The second 180° of the movemenmt is pivoting about a second common axis defined by collinearity of two axes, namely the axis of pivoting of the first limb of the first pin member within the first journal of the first hinge plate and the axis of pivoting of the second limb of the second pin member within the second journal of the second hinge plate.  In each pin member, the parallel limbs are joined at their ends by cross limbs so that each pin member has a sustantially rectangular configuration.

Abstract: STRUCTURES REINFORCED BY A COMPOSITE MATERIAL Structures, such as pressure vessels or pipes, for the storage and transportation of fluids under pressure are wrapped with a composite material including a high-strength unidirectional filament material in a matrix of a flexibilized isophthalic polyester resin which has an elongation at least equal to the elongation of the material of the structure. The index of refraction of the resin is matched to the index of refraction of the filament material so that the pressure vessel is visible through the wrapping. The resin discolors when exposed to a heat above which the material of the structure weakens, thus acting as an indicator that the structure is unsuitable for use.

Abstract: ABSTRACT OF THE DISCLOSURE     An automotive navigation system wherein a storage means included in the system has not stored therein picture information of an actual map, but instead has stored therein the geographical names and the geographical positions of points as well as the declination of the earth magnetism of the points.  When the geo-graphical names of a departure point and a destination point are entered through an input unit, a control circuit reads out from the storage means the respective positions of the points entered.          The control circuit controls a display unit to display on a dis-play screen marks respectively indicating the departure point, the destination point, and the current position of a vehicle on an adequately reduced scale determined by the positions of these points.  A point nearest to the current position of the vehicle while the vehicle is being driven is determined and retrieved by the control circuit from the storage means.  On the basis of the declination information of this retrieved point, the detected vehicle heading direction is corrected to make an accurate compu-tation of the current position of the vehicle.

Abstract: OPTICAL TRANSMISSION FILTER             Abstract  of The Disclosure The present invention deals with an optical transmission filter for effecting differential phase delay upon light in a beam polarized in a P dimension, as a function of position within the filter aperture.          The filter employs two lenses of birefringent material, the crystal optic axes of the respective lens materials being oriented in mutually orthogonal positions and at a 45° angle to the P dimension.  The lenses have their adjacent surfaces respectively concave and convex with the same radius of curvature and their non-adjacent surfaces flat.      The phase response of the filter is a function of the radial distance of a beam element from the filter axis with spherical lenses and a function of a linear coordinate distance from the filter axis with cylindrical lenses.  A two-part construction for one lens, which permits adjustment of the difference in center thicknesses between the two lenses, allows adjustment of the differ-ential phase delay with respect to a spacial reference.
