    Abstract: In a color picture tube in which a plurality of beams are made to intersect each other at a location between the beam generating sources and the color screen and are focused on the latter by a main focusing lens positioned to dispose its optical center substantially at the location where the beams intersect so that beams emerge from such lens along divergent paths, first and second spaced plates are disposed at opposite sides of each of the divergent paths to electrostatically deflect the respective beam and cause convergence of all of the beams at a common area on the screen when the first and second plates are at different potentials, a high voltage is generated from a horizontal deflecting pulse provided for causing the beams to scan the screen and such high voltage is applied to an anode electrode of the tube and also to each first plate, and a static convergence deflecting voltage is obtained by dividing the aforementioned high voltage and is applied as the potential difference between the first and second plates by which the respective beam is to be deflected. Further, a dynamic convergence deflecting voltage, comprising both parabolic and sawtooth voltages is generated in response to the horizontal deflecting pulse and is superimposed on the static convergence deflecting voltage with provision being made for separately adjusting both deflecting voltages.

    Abstract: A vertical deflection circuit which has an output stage formed in the type of single-ended push-pull amplifier and a voltage supplying circuit with a charge storing device connected between a voltage source and the output stage. The voltage supplying circuit supplies a voltage from the voltage source to the output stage and simultaneously charges the charge storing device during a retrace period and also supplies a voltage lower than the voltage of the voltage source to the output stage by discharging of the charge storing device during a trace period.

    Abstract: A single-gun, plural-beam-type color television picture tube in which three electron beams representing different color signals are focused by a single lens, after which two of the beams diverge. The two divergent beams are reconverge by convergence deflecting means so they will intersect with the third beam at a common point at a beam-selecting grid, from which point the beams again diverge to impinge on respective color phosphors which together represent a color picture element. Misconvergence, i.e., reconvergence of the two divergent beams to a point other than to the common point of intersection with the third beam, which arises from manufacturing inaccuracies such as the misorientation of the convergence deflecting means with respect to the single electron gun of the tube, or the misorientation of the aperture of the beam-generating means of the tube, is compensated for by the provision of convergence deflecting means which exerts upon at least one of the divergent beams an electric, or Coulomb, force which varies in its direction in accordance with the position at which the beam enters and passes through the convergence deflecting means. Thereby, variations in the direction of the electric force compensates for variations in the position at which the beam is introduced to eliminate the misconvergence which arises from the above-mentioned manufacturing inaccuracies.

    Abstract: A DC power supply circuit of the switching or chopping type for converting a voltage from an AC power source or from a DC power source into a predetermined DC voltage and supplying the converted DC voltage to a load, comprises a converting transformer having first and second primary windings and a secondary winding and first and second switching circuits connected to the first and second primary windings, respectively, and being selectively operated for switching or chopping the voltage applied from the AC or DC power source to the respective primary winding thereby to produce a pulse voltage at the secondary winding of the converting transformer to which a rectifier circuit is connected. The converted DC voltage obtained at the output of the rectifier circuit is connected. The converted DC voltage obtained at the output of the rectifier circuit is compared with a reference voltage, and the switching circuits are controlled on the basis of such comparison for maintaining the converted DC voltage at a predetermined level.
