An electron source device includes a porous layer (for example, porous alumina layer) which is composed of an insulator and has many microscopic holes provided in a direction perpendicular to a main surface, and first and second conductor layers placed on both sides of the porous layer, and is characterized in that the current density I/S is 1 μA/cm2 or higher when a direct-current voltage is applied between the second conductor layer and the fist conductor layer while using the second conductor layer as an anode. In this case, S represents the overlapping area of the first conductor layer, the second conductor layer and the porous layer. Consequently, an electron source device having a high electron emission ability and a long life even when the degree of vacuum is low can be obtained at low cost, and hence, a display having a high luminous efficiency and high reliability can be realized.

摘要:
An image display unit comprising a high-resistance gap section disposed between a grounding section and the outer peripheral edge of a metal back layer so as to surround the outer peripheral edge, the high-resistance gap section having a surface roughness of 1.0 to 15.0 μm. The high-resistance gap section can have a high-resistance coating layer with a surface resistivity of 1×109 to 1×1015 Ω/□. The high-resistance gap section can be formed of plural regions so disposed that their surface roughness or surface resistivity sequentially increases from the inner side toward the outer side. Accordingly, surface discharge from the outer peripheral edge of a metal back layer is restricted to prevent the destruction or deterioration of an electron emission element and a fluorescent surface.

The high density slave magnetic recording media comprising on a non-magnetic substrate a magnetic recording layer coated with magnetic hexagonal ferrite powder along with a binder component to transfer the digital signals stored on the master magnetic recording media by the magnetic contact duplication process, is characterized in that the perpendicular squareness ratio of the magnetic recording layer is not less than 0.58 and is less than 0.7, center line average roughness Ra is not more than 0.01 .mu.m, and the number of convex projections whose pitches are 10 to 90 .mu.m and whose height is not less than 0.03 .mu.m pp (bottom to top) is not more than 10 per 1 mm of running direction. The slave magnetic recording media permits the functionally enough duplication efficiency of digital signals by the magnetic contact duplication process and can considerably curb the error rate during the reproduction of the duplicated digital signals.
