Abstract

PURPOSE: To increase the dustproof efficiency and thus to increase the dielectric strength as well as to prevent the leak current by inserting the collecting electrode inside the Braun tube and then applying the voltage between the inner surface of the tube and the conductive film to be coated.
CONSTITUTION: As for color Braun tube 11, collecting electrode 8 is inserted to the inner side of tube 11 from cylindrical neck part 1 and then fixed with guide 9 composed of the insulator material. On the other hand, anode terminal 7 is provided at the prescribed position on the outer surface with connection to conductive film 6 coated on the inner surface of funnel part 2. Then electrode 8 and terminal 7 are connected to the plus and minus sides of high voltage power source 10 respectively, and the fixed voltage is applied to collect the dust electrically to electrode 8. Thus, electrode 8 is drawn outside the tube, ensuring the highly efficient exhaustion of the dust.
