ABSTRACT:
A frit-drying system for cathode ray tubes is to utilize VHF and it is to evaporate organic matters which are contained in the frit spread on the funnel by a VHF dielectric heating method that matters with dipole components are heated from the inner part of the frit by dielectric loss of VHF when the VHF is injected on the matters with dipole components. A frit-drying system for cathode ray tubes utilizing VHF includes a funnel transferring device, and a main furnace body which defines the VHF room for drying frit therein, a VHF oscillating device, and VHF induction path which inducts VHF generated from the VHF oscillating device into the main furnace body.
