Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A process for constructing a gaseous discharge display/memory device comprising assembling discrete parts, including (1) a pair of transparent flat members with printed circuit metallization and dielectric coating formed on said printed circuit metallization and said transparent flat members, (2) a plurality of elongated spacer rods and (3) a heat fusible sealing material, heating said assembly of discrete parts to a temperature above the softening point of said heat fusible sealing material but below the softening temperature of said assembled discrete parts to effect fusion of said sealing material and said transparent flat members into an impermeable envelope for confining a predetermined volume of gas whereby the space between the walls of said envelope is controlled by the vertical dimension of said elongated spacer rods.
Claim 2
Dependent Claim
125 words
A process for constructing a gaseous discharge display/memory device comprising assembling discrete parts, including (1) a pair of transparent flat members with printed circuit metallization and dielectric coating formed on said printed circuit metallization and said transparent flat members, (2) a plurality of elongated spacer rods and (3) a heat fusible sealing material, heating said assembly of discrete parts to a temperature above the softening point of said heat fusible sealing material but below the softening temperature of said assembled discrete parts to effect fusion of said sealing material and said transparent flat members into an impermeable envelope for confining a predetermined volume of gas whereby the space between the walls of said envelope is controlled by the vertical dimension of said elongated spacer rods.
Claim 3
Dependent Claim
21 words
The process according to claim 1 wherein there is assembled a tubulation for exhausting and backfilling the gaseous discharge display/memory device.
Claim 4
Dependent Claim
33 words
The process according to claim 2 including the further step of evacuating and backfilling said envelope through said tubulation with a predetermined volume of a gas at a pressure suitable for display usage.
