DEPOSITION DEVICE FOR THIN DISPLAY TUBE

PURPOSE:To prevent the occurrence of cracks on a surface container by pressing the surface container with surface container dampers storing springs for positioning, then welding the surface container and a back container. CONSTITUTION:A back container 3 is fixed to a base 6 with back container clampers 1. Surface container reference attaches 4 are moved while a surface container 2 is kept in contact with surface container dampers 5 so that the reference position of the surface container 2 coincides with the reference position of the back container 3, then the surface container reference attaches 4 are fixed with hexagonal socket head bolts 7. After the completion of assembling, this deposition device is put in an electric furnace, and the surface container 2 and back container 3 are welded with a deposition agent such as frit glass arranged at the connection face between the surface container 2 and back container 3. The positioning of the surface container 2 can be performed only by adjusting the attaches 4, the action is easy, the thermal expansion by heating is easily absorbed, and cracks on the surface container 2 can be prevented.
