Title: Gas discharge display panel and its protective film forming method
Inventor: KOIWA ICHIRO
IPC: H01J11/42
Filed: 1993-12-27
Abstract: PURPOSE:To provide a protective film suited for mass production further with a better panel characteristic obtained, in an AC type PDP. CONSTITUTION:An electrode, wall charge accumulating dielectric 14 and a protective film 16 are successively provided on a soda lime glass substrate 18. The protective film 16 is formed in a sintered body composed of MgO grains 16a, 16b of different grain size and an MgO binder 16c. A precursor of liquid phase serving as MgO by burning is used to form the binder 16c. Thus, mass production of the protective film 16 is facilitated. In the case of burning the precursor at a 580 deg.C or less temperature such as preventing a soda lime glass from being denatured, crystal grain density of the binder 16c is difficult to increase. However, since a grain size is different in grains 16a, 17b, distribution density of these grains in the protective film 16 can be increased. Accordingly, by forming these grains in a monocrystal grain, crystal grain density of the protective film 16 can bee increased.

Abstract: PURPOSE:To lower the height of mounting, and to make it possible to obtain a ferrite core having high operating efficiency by a method wherein the width and the height of the core, the width of the center leg and external leg, the back depth, and the distance between the center leg and the external leg satisfy prescribed conditions. CONSTITUTION:When core width is (a), core height is (b), center leg width is (c), outer leg width is (d) back depth, is (e), and the distance between the center leg and the outer leg is (g), the conditions shown in the formula I separately mentioned are satisfied simultaneously. To be more precise, the core height, which satisfies the conditions of the formula I, is low, also even after a winding has been wound, the increase in height is small, and as surface area can be made larger, heat-radiating property of the core is excellent. Also, almost no partial magnetic saturation is generated inside the core, and the degree of heat generation is low. As a result, when the core is applied to a transformer and a choke coil, its mounting height can be suppressed, and a ferrite core having high operating efficiency can be obtained.
