Title:
MANUFACTURE OF CATHODE-RAY TUBE
Document Type and Number:
Japanese Patent JP3398996
Kind Code:
B2
Abstract:
PURPOSE: To make the orbital slippage of the cathode ray in a color cathode-ray tube after the complition correctable.
CONSTITUTION: An AC attenuating magnetic field is given by a magnetic field generating device which consists of coils 6A and 6B different from a bias magnetic field generating device, under the condition to give a necessary bias magnetic field by a bias magnetic field generating device which consists of three pairs of coils 4A, 4B, and 4C provided to make square each other on the axes of the tube surface to a cathode-ray tube 3, so as to magnatize the metal members in the cathode-ray tube.
