    Abstract: PROBLEM TO BE SOLVED: To overcome the loss of hydrogen in a screen assembling phase by containing a hydrogen adding stage of one getter suitable for hydrogen addition after a drying stage of a process including the drying stage and sealing stage. SOLUTION: A device 2 is arranged in a drying region 48, hydrogen is added into a reservoir 36 from a cylinder 40 via a needle-like valve 42, and a pressure measuring means 44 measures the hydrogen pressure in a reservoir 36 and fixes a getter 50 into an exhaust tube 28. Various elements of an electric field emission device 2 are kept under vacuum and are dried at the temperature of 300-450 deg.C for one or several hr. A hydrogen adding stage is required next, and hydrogen is added to one or more getters 50 in this stage. A getter 50 absorbs the hydrogen trapped in the device 2 during cooling, and it maintains the hydrogen pressure loaded in a sealing phase and the equilibrium pressure depending on the volume of the device 2 and the quantity and type of one or more getters.

    Abstract: The invention concerns a device comprising at least an electron source with field effect in a closed structure defining an internal space which contains a reducing gas for oxidising the material emitting the electron source. The invention is characterised in that the reducing gas comprises a gas of formula NxHy with x = 1 or 2 and y = 3 or 4, advantageously under pressure ranging between 10 mbar and 10 mbar. The invention also concerns methods for making such a device and appliances therefor.

    Abstract: The method involves positioning, sealing (8), returning the device to the atmosphere, putting under vacuum and drying after which the getter (50, 51) is hydrogenated and the device closed. The getter may be introduced after sealing and return to the atmosphere or simply after sealing. Following absorption of hydrogen, the device is returned to normal temperatures and may be operated for a period to degas the phosphors during a re-pumping stage before closure. The getter may advantageously be kept cool until hydrogenation, then activated by inductive heating. The getter is zirconium or titanium with either one from vanadium, manganese, iron, cobalt, nickel or chromium or two from vanadium, manganese, iron, cobalt and chromium.
