Abstract: A front substrate and a rear substrate are laid on each other with a sealing frit therebetween. The front substrate, the rear substrate and the sealing frit are heated in a chamber and impurity gas is exhausted from both of the substrates by lowering internal pressure of the chamber. The sealing frit is melted in the chamber by further heating the front substrate, the rear substrate and the sealing frit. The sealing frit is solidified in the chamber and sealing up the front substrate and the rear substrate.

Abstract: In a substrate manufacturing process for color plasma displays, it is made possible to form a phosphor coat in a desirable form all over a panel by introducing a step to coat the whole surface of a luminescent display section with a paste containing white particulates of titanium oxide or the like, which are finer than phosphor powder, after barriers are formed on a back substrate and before the discharge cell inside is sequentially coated with phosphors for different colors to make up luminescent pixels. By applying the particulate paste to the unfired barrier portion, which is then in a very porous state, before the phosphor coating stage, collective firing of the barriers and the phosphor layers is made possible.

Abstract: Disclosed is a refrigerator oil composition comprising at least one base oil selected from mineral oils and synthetic oils, and at least one polyether compound having a kinematic viscosity of from 200 to 10000 mm.sup.2 /sec at 100.degree. C. The composition has an excellent lubricating property, while specifically improving the lubricity of bearings. This is effective for preventing bearings from being seized and fatigued, and is suitable as a lubricating oil in refrigerators using hydrogen-containing Flon refrigerants, such as R134a, that do not cause environmental pollution.

Abstract: In an electroluminescence panel, first and second charge injection refraining layers are formed between transparent electrodes and a first insulating layer and between back electrodes and a second insulating layer, respectively, and first and second charge injecting layers are formed between the first insulating layer and an emitting layer and between the second insulating layer and the emitting layer, respectively. The charge injection refraining layers suppress the injection of charges into the first and second insulating layers to enhance the ability of the panel to withstand the applied voltages, and the charge injecting layers inject a large quantity of charges into the emitting layer to increase the luminance. Further, the fabricating efficiency is not lowered.
