Abstract: PROBLEM TO BE SOLVED: To reduce a gaseous product by disposing a seal made of a glass rod and a spacer having a higher melting point and a greater height at the outer periphery of a screen between upper and lower plates respectively having an anode and a cathode, followed by heating up to a predetermined temperature in a vacuum. SOLUTION: A seal 20 formed of a soluble glass rod is stuck to the outside circumference of an acting area of a screen on a plate 4 with an anode formed thereon. A few glass spacers 22 are temporarily interposed between the seal 20 and the outside circumference of the acting area of the screen. A melting point of the glass of the spacer 22 is higher than that of the glass forming the seal 20, and considerably higher at that. A plate 1 with a cathode/grid formed thereon is placed on the plate 4, is heated in a vacuum at temperatures higher than the melting point of the seal 20 but lower than the melting point of the spacer 22, followed by mechanical pressing. Consequently, the spacer 22 is crushed, so as to be sealed therearound in a predetermined height by melting of the seal 20.

Abstract: The screen is formed of two electrodes separated by an internal space. One of the electrodes is supported by a thin substrate and a thick rigid plate. The internal space is defined by a peripheral framework between the electrodes outside of their usable surface. The second electrode is carried on a thick rigid plate formed of a thick substrate. The internal face of the substrate forms the second electrode. The plate associated with the first electrode forms a base of the screen and has an orifice through.

Abstract: The anode includes electrode bands (17) each of which incorporates a resistive band (18) which is a transparent electrically conducting non-stoichiometric oxide, esp. indium tin oxide, fixed by the quantity of oxygen contained in the oxide. Associated with each band are two parallel polarisation bands (19) on either side and joining to the conductor connecting the electrodes. Phosphor bands (7) are deposited onto the resistive bands. The polarisation and resistive bands may be of the same material but with the polarisation band having lower resistivity. An insulator (8) separating the electrode bands serves as a mask to increase the resistivity of the resistance bands by heat treatment in an atmosphere of oxygen. Alternatively, the thickness of the material may vary the resistivity with the insulator acting as a etching mask. Three such assemblies are used to mfr. a colour screen.
