Abstract: A method for making an enameled steel sheet includes the steps of spraying a slurry to form a slurry layer onto a surface of a substrate and firing the slurry layer. In this method, the slurry has a static surface tension of 50 dyne/cm or less and an apparent viscosity of 500 mPa·s that is measured with a model E viscometer at a rotation of 100 rpm. Alternatively, the method includes a step of spraying a slurry for forming an enamel layer onto a surface of a substrate, wherein the substrate is vibrated when the slurry is applied or when the slurry applied is still fluid.

Abstract: An electrophoretic matrix display panel is composed of a first insulating substrate having a first set of strip-shaped parallel electrodes thereon and a voltage non-linear resistive layer on the first set of parallel electrodes. Dot-shaped intermediate electrodes isolated from each other are positioned on the voltage non-linear resistive layer, and an electrophoretic suspension layer consisting of a suspending medium and at least one electrophoretic material suspended therein is placed over the intermediate electrodes and contained thereon by a frame. A second set of parallel electrodes extending in a direction transverse to the direction of the first set of electrodes is placed over the frame and the electrophoretic suspension layer, and a second insulating substrate is provided thereover. The two sets of parallel electrodes cross to define cross points at which the dot-shaped intermediate electrodes are positioned and which constitute picture elements of the matrix display panel.

Abstract: This invention relates to an X-Y matrix type electroluminescent display panel. The panel includes a transparent insulating substrate, transparent and parallel X-electrodes of strip shape provided on said transparent insulating substrate, a D.C. electroluminescent layer provided on said transparent parallel electrodes; parallel Y-electrodes of strip shape provided on said D.C. electroluminescent layer, the direction of said Y-electrodes being perpendicular to that of said X-electrodes, said X- and Y-electrodes and said D.C. electroluminescent layer defining display elements at the intersections of said X- and Y-electrodes; and a mesh-shaped insulating layer, preferably of black color, for insulating said display elements from each other at least in the vicinity of said X-electrodes. Because of the mesh-shaped insulating layer, it becomes possible to achieve uniform "forming" of said D.C. electroluminescent layer and to improve the brightness and contrast of the resultant display panel.
