Title: Deflecting yoke provided with misconvergence correction device
Inventor: KEN KAKUSAN
IPC: H01J29/76
Filed: 1993-03-09
Abstract: PURPOSE: To prevent the over-correction of the intermediate section of an image which occurs during the correcting process of a vertical coma error by nonlinearly controlling a current itself flowing to correction coils by using a pair of correction coils composed of single-layer coils. CONSTITUTION: When a saw-tooth voltage from a vertical oscillation circuit is applied across vertical deflection coils LV21 and LV22, a barrel vertical deflection magnetic field is generated from the coils LV21 and LV22, and an electron beam which is radiated from an in-line type electron gun is deflected vertically. When the voltage is applied, the electric currents flowing to the coils LV21 and LV22 flow to a pair of correction coils CF21 and CF22, composed of single-layer coils connected in series with each other and a pin-cushion vertical deflection magnetic field is generated from the coils CF21 and CF22, The currents flowing to the coils CF21 and CF22 can be controlled by adjusting resistors R21 and R22.  If the resistor R21 is set to a small value, the value of the current flowing to the coil CF21 can be reduced before a diode pair D21 and D22 is turned on, since the value becomes smaller as the diode pair D21 and D22 is gradually turned on.
