  • Bushing temperature controller
    Patent number: 7269974
    Abstract: A bushing temperature controller includes a transformer 3 which supplies a main current I1 to the bushing 2 for accommodating molten glass, and regulation current supply units 7 and 8 which are adapted to supply regulation currents I2 and I3 either in phase with the main current I1 or in phase inverted to the main current I1 to a portion of a region to which the transformer 3 applies the current. Thus, the temperature control of partial regions 2a and 2c in the region to which the current is applied can be performed in a wide temperature range.
