Abstract: SELECTION CONTROLLED PRINT IMPRESSION CONTROL           FOR SINGLE ELEMENT IMPACT PRINTERS     Abstract of the Disclosure The impact velocity with which a single element printer prints is determined by the velocity with which the printing element is propelled toward the record sheet. The mechanism disclosed herein is capable of adjusting the velocity with which a print element is projected toward the page such that the impact velocity and, thus the impact forces which are related to the velocity, are controlled and varied to provide a minimum of compromise with respect to printing forces and, thus, print quality. The control of the velocity with which the print element is propelled against the record sheet is accomplished by a cam which rotates with the print element during character selection and has thereon a plurality of rises corresponding to a displacement of a cam follower engaged with a print cam.  The print cam is formed to present, in a plurality of different planes perpendicular to its axis, a like plurality of cam profiles and rises.  By shifting the print cam follower from one plane to another along the axis of the print cam, the velocity may be selected and controlled.  This velocity selection is a direct result of the amount of rise in the cam attached to the shaft which rotates the print element.  Thus, print element position, in response to conventional keyboard selection, directly controls the velocity of the print element derived from the rotation of the print cam and, therefore, controls impact force.

Abstract: QUALITY CONTROL COPYING DEVICE            ABSTRACT       The present invention concerns copying apparatus which automatically controls the quality of copies. The copying apparatus includes a density detector for detecting the frequency of occurrence of density values along a scanning line of a document to be copied, i.e., the frequency distribution of density values is determined. When the frequency distribution has at least three maxima, a smoothing device smooths the frequency distribution via a predetermined filter function till the frequency distribution has one or two maxima. In the event the frequency distribution has one or two maxima, a density detecting device detects at least one density value according to a maximum or minimum value of the frequency distribution. A control device then controls the copy quality of a reproduced image according to the density value.

Abstract: RCA 75,226 Abstract of the Disclosure A self-converging deflection yoke having toroidally-wound vertical deflection coils incorporates a pair of magnetically permeable field formers mounted on either side of the yoke.  The field formers shunt a portion of the external field flux to the vicinity of the electron gun assembly where they form a pincushion-shaped field which aids in vertical coma correction.  In one embodiment, a yoke comprising planar-wound vertical coils incorporates both coma-correcting rear field formers and a pair of front crossarm assemblies for providing side-pincushion correction.  The resultant yoke provides covergence of electron beams free of coma and side-pincushion distortion with reduced sensitivity to transverse motion.  In another embodiment, similar results are obtained without the front crossarms by vertical deflection coil having a nonradial winding configuration.
