Abstract

PURPOSE: To make it possible to remove a fault of an outside magnetic field effectively by a simple constitution by equipping a coil where a commercial AC current flows.
CONSTITUTION: In the top and reverse surfaces of television receiver container case 1, coils 2 and 3 are arranged and held. Those coils 2 and 3 are applied with a commercial AC current 10 by way of variable capacitor 11 and variable inductance 12 to provide in container case 1 a vertical magnetic field out of phase with the outside field. Therefore, when a television receiver is installed in container case 1, the magnetic field provided by coils 2 and 3 is considered to be applied uniformly in the vertical direction in parallel to the screen of the Braun tube of the television receiver, so that this magnetic field and outside magnetic field opposite in direction will cancel each other effectively.
