Title: Interference magnetic field reducing method for cathode ray tube
Inventor: KATOU ATSUSHI
IPC: H04N9/29
Filed: 1981-12-16
Abstract: PURPOSE:To prevent picture distortion of a cathode ray tube, by reducing the effect of induced magnetic field from distribution lines and electric machines, through the provision of a single closed circuit coil not requiring any power supply at the outside of the cathode ray tube. CONSTITUTION:Closed circuit coils 2a-2d are placed at the circumference of a cathode ray tube 1. If a magnetic field interlinked with the coils 2a-2d exists, a coil interlinked with the magnetic field induces a current which cancels the interlinked magnetic field. Then, the interlinked magnetic field can be reduced. Thus, the picture distortion of the cathode ray tube 1 can be prevented to the utmost.
