METHOD OF MANUFACTURING OF VACUUM DEVICE, VACUUM DEVICE CASING, AND VACUUM CHAMBER Russian patent published in 2015 - IPC H01J9/00 

Abstract RU 2558380 C1

FIELD: machine building.

SUBSTANCE: device casing is located in the vacuum chamber on the holder with hole upwards, at that the hole axis is located vertically, and after device evacuation, and its degassing in the vacuum chamber the casing hole is sealed by the sealing material application on it, for example indium droplets. The vacuum chamber for the device manufacturing is equipped with the device for dosing supply of the sealing material, that contains cone cylinder, with sealing material, equipped with hole in bottom part and fixing element closing this hole. After warm-up the device is located under the device of the sealing material application, coinciding the casing hole axis with hole axis of the cone cylinder of the sealing material dosing device. The fixing element opens the hole, at that the dosed portion of the sealing material drips on the device casing hole under it, and securely seals it.

EFFECT: increased quality of manufactured vacuum device due to absence of the projecting parts on its casing, reduced labour intensity, and increased production effectiveness of the device.
