PURPOSE:To keep the temperature of glass constant invariably by burying a thermocouple in a glass burning table for the purpose of keeping the temperature of the bead glass-burning table under the same conditions invariably. CONSTITUTION:The part of bead glass F of bead-glass burning table 6 and thermocouple 13 are buried, which are connected to thermometer 14 which a relay and then, pilot lamp 15 is provided which comes on by the relay. The electron-gun assembling device mentioned above is able to keep the temperature of bead glass constant invariably, so that stable assembling operation for electron guns can be attained. |
