 Image Number 6 for United States Patent #5177411.
A CRT correcting circuit comprises a correcting deflection coil excited by an alternating signal of a vertical period, a capacitor connected in parallel to the correcting deflection coil to form a resonance circuit, a first field effect transistor of a first conduction type, and a second field effect transistor of a second conduction type. The first and second field effect transistors are turned on and off simultaneously by a pulse signal of a horizontal period. The CRT correcting circuit is capable of operating at a low power consumption and has a simple circuit construction.
