Title: Phosphor screen and its manufacturing method
Inventor: SEKIGUCHI AKIRA
IPC: H01J29/18
Filed: 1982-04-26
Abstract: PURPOSE:To apply an adhesive force that will not cause any practical problem to the inner surface of a faceplate and prevent any deterioration in the characteristics of a phosphor by making the faceplate composed of the two-layer films of water soluble and insoluble phosphors and setting the rate of water insoluble coating to 0.015-0.15mg per cm<2>. CONSTITUTION:In order to improve an adhesive force to the inner surface of a water soluble phosphor, a phosphor screen with the adhesion that will not cause any practical problem is obtained by first forming the exceedingly thin auxiliary film of a water insoluble phosphor and then the water soluble phosphor film thereon. In this case, if the rate of coating of the water insoluble phosphor is below 0.015mg per cm<2>, the adhesion is not improved and if it exceeds 0.15mg, the characteristics of the water soluble phosphor are damaged by the water insoluble phosphor. However, if the rate of coating ranges from 0.015-0.15mg, the adhesion can be improved without deteriorating the characteristics of the water soluble phosphor that is the main phosphor of the phosphor screen.

Abstract: PURPOSE:To reduce the damage of a sample surface, which is caused by scattering electron rays, by making the peripheral parts of the holes of an objective lens, through which focusing electron rays pass, to protrude close to the sample surface in circular cones. CONSTITUTION:An upper and a lower magnetic pole 1b and 1a of an objective lens 1 protrude toward a sample 2 in circular cones, and the extreme end of the lower magnetic pole 1a especially is sharpened. Owing to the above constitution, a widely reduced proportion of reflected electron rays 4 discharged from an illuminated point of the sample 2, on which focusing electron rays 3 are focused, collide against the lower magnetic pole 1a. In addition, when a small amount of reflected electron rays 4 collide against the pole 1a, most part of scattering electron rays 5 are dispersed in such directions that the sample 2 is not influenced by the rays 5. Consequently, the deterioration of the property of the sample 2 caused by the scattering electron rays 5 is widely reduced.
