Abstract
PURPOSE: To eliminate a uselessness of mercury, further to make the promotion of reducing an environmental contamination due to the mercury, by supplying an exhaust head mercury as well as sealing the mercury to the bulb, in accordance with the detected signal resulting from detecting the bulb whether good or not at the final stage of degas exhaust.
CONSTITUTION: At the final stage of a degas exhaust unit 6 arranged and installed to a turn table 1, is provided a bulb quality detecting unit 10, in which the construction is made by a bulb presence detector 16, comprising a phototube 14 and a light sensing element 15 facing to each other with a bulb 12 put between, and a bulb internal pressure detector 19, connecting an output, of thermocouple vacuum gage 18 linked to a vacuum suction tubing 17 jointed to an exhaust head 3, to the meter relay. A signal controller 11 is provided with a delay relay built in for processing a detected signal, from the above detecting unit 10, transmitted to a mercury and gas sealing unit 7 and to a mercury quantity scaling and supplying unit 5. In this way, a contamination of working environmemts due to the mercury can be eliminated without uselessly using the mercury.
