Title: Cathode structure
Inventor: SAITO SHUNJI
IPC: H01J1/20
Filed: 1991-12-24
Abstract: PURPOSE:To materialize the long life of a cathode structure without its loss due to useless evaporation of magnesium by providing a high melting point metal layer where magnesium is hard to diffuse by heat on the rear surface of a cathode basic body. CONSTITUTION:A high melting point metal layer 14 consisting of tungsten is formed on the rear surface of a cathode basic body 12 by sputtering method. Then, an emitter layer 13 is formed by applying O layer of 50:40:10mol.% (Ba, Sr, and Ca) on the other face. It turns out that the magnesium inside the basic body 12 is restrained from evaporating from the rear surface side by providing a layer 14. Therefore, most magnesium staying inside the basic body 12 reacts upon the oxide of the layer 13 on the main surface, of the basic body 12 so it turns out that a material capable of contributing to emission may be generated. Therefore, any loss due to useless evaporation of magnesium can be eliminated so the long life can be materialized.

SOLUTION: A CCD 1 reads the images by the density of 600dpi, converts them to digital signals and performs shading correction and then, luminance and density transformation is performed in a logarithmic transformation part 2. For the density signals, in an image area separation part 5, the judgement signals 8 of whether the picture element under consideration is a character thin line or a part of the halftone part are generated for the respective picture elements of image signals. In the meantime, an interpolation part 4 interpolates raster-like multi-valued image signals to 1200dpi and they are turned to binary signals 9 in a pseudo halftone processing part 6 accompanying error correction. Also, the multi-valued image signals of the density of 600dpi are turned to the binary signals 10 in the pseudo halftone processing part 7.  In this case, a selector MPX 11 switches the binary signals 9 and 10 by the judgement signals 8, outputs them to a binary recorder 13 and records them by 1200dpi. In the case of 600dpi, they are continuously handled for two dots.
