Abstract: MOTION PICTURE SYSTEM                         ABSTRACT           A method is described for producing and projecting a theater quality entertainment motion picture, by photographing and then projecting the motion picture on a screen, which creates an unusually vivid impression of realism.  The film frames have a resolu-tion of over 40 line pairs per millimeter,  and each frame has an area of at least 230 square millimeters (0.36 square inch), which creates more than 10 million pixels per frame on the film and on the screen.  The illumination level on the screen is greater than 16.5 foot lamberts.  The film frames are photographed and projected at a predetermined constant rate of more than 50 frames per second, such as 60 fps.  The high resolution and light level, combined with the unusual-ly high frame rate, has been found to produce an unusually vivid impression of realism.

Abstract: Abstract:    A semiconductor device comprises a control electrode for forming carriers at a junction interface between first and second layers of different materials and for controlling the carriers.  A first electrode is electronically connected to the carriers and a second electrode region is provided for taking out the carriers in a direction perpendicular to the junction interface.  Since the two-dimensional carriers are caused to flow as a current in the direction perpendicular to the plane on which the carriers exist, a large current can be derived as the operating current.

Abstract: Abstract POINTING COMPENSATION SYSTEM FOR SPACECRAFT INSTRUMENTS     A closed loop system reduces pointing errors in one or more spacecraft instruments.   Associated with each instrument is a means (3) for commanding motion in that instrument  and  a  pointing  control  system  (5)  for imparting motion  in that  instrument  in response  to a command (4)  from the commanding means (3).  Spacecraft motion   compensation   logic   (25)   compensates   for instrument pointing errors caused by instrument-motion-induced  spacecraft  motion.   Any  finite  number  of instruments  can  be so compensated, by providing each pointing control system (5) and each commanding means (3),  for  the  instruments  desired  to  be  compensated, with a link to the spacecraft motion compensation logic (25).  The spacecraft motion compensation logic (25) is an electronic manifestation of  the algebraic negative of  a  model   of  the  dynamics  of  motion  of  the spacecraft.   An  example  of  a  suitable  model,  and computer-simulated results, are presented.

Abstract: Abstract A video display apparatus incorporates a picture tube, such as a square planar picture tube, that includes a phosphor screen located on a faceplate having an aspherically curved geometry that produces a relatively flat surface contour.  Deflection circuitry generates line and field scanning currents in respective line and field deflection windings to enable the electron beams of the picture tube to scan a raster on the phosphor screen. The electron beams are subject to a scanning error that results in raster distortion, such as side pincushion distortion. A parabola generator produces a parabolic modulation of the scanning of the electron beams to generally correct the raster distortion while retaining a residual error due to the aspherically curved geometry of the faceplate.  A nonlinear waveshaping circuit modifies the parabolic modulation of the scanning current in accordance with the aspherically curved geometry to provide additional modulation of the electron beam scanning for correcting the residual error.  The nonlinear waveshaping circuit includes a current source and a switched current divider that is responsive to a threshold level of the parabolic voltage developed by the parabola generator.
