摘要： A deflection yoke attached to a color cathode ray tube forming multiple electron beams arranged in line, and in particular a deflection yoke having convergence correction apparatus. Circuit components such as a plurality of resistors, variable resistors, and diodes are connected in parallel with vertical deflection coils. A part of a vertical deflection current flowing through the vertical deflection coils is diverted to the circuit components. Furthermore, the amount of the diverted current is made adjustable so that it will differ between a former part of a vertical deflection period and a latter part thereof. As a result, horizontal line misconvergence at upper and lower ends of the screen can be completely corrected.

摘要： A cathode-ray tube apparatus capable of reducing a high frequency electric field radiated from the deflection yoke and the deflection and high voltage circuit to the outside of the cathode-ray tube apparatus. Mounted on the deflection yoke or on the cathode-ray tube are an induction coil for generating a pulse voltage opposite in polarity to a high pulse voltage applied to the h and an electric field cancellation electrode made of a conductive wire to which the opposite polarity pulse voltage is applied. When the opposite polarity pulse voltage is applied to the electric field cancellation electrode, the electric field cancellation electrode radiates an electric field opposite in polarity to the high frequency electric field radiated from the deflection yoke to the outside of the cathode-ray tube apparatus to reduce the intensity of the high frequency electric field.

摘要： At least two pairs of auxiliary coils are disposed externally on a deflection yoke at positions which are symmetric with respect to the central axis of a horizontal direction of said deflection yoke and which are separated from each other in the direction of the axis of a cathode ray tube. At least two pairs of auxiliary coils are respectively disposed in front of and at the back of the longitudinal center of a magnetic core. The auxiliary coils have a horizontal length which is longer than its another length. A horizontal deflecting current is supplied to the first pair of auxiliary coils in the direction in which unnecessary radiant magnetic fields generated in front of and at the back of the deflection yoke are suppressed, and a horizontal deflecting current is supplied to the second pair of auxiliary coils in the direction in which an unnecessary radiant magnetic field generated at the back of the deflection yoke is intensified. In consequence, unnecessary radiation can be suppressed simultaneously in front of and at the back of the deflection yoke by a correction apparatus which has a simple structure and which requires no large space.

The peaks are opposite in direction to the horizontal magnetic field generated by the deflection yoke body, respectively, with same ratio to the deflection magnetic field, so that the undesired magnetic field portions are under-corrected in the front portion and over-corrected in the rear portion.
