Title: Manufacture of germanium-oxide film for picture tube target
Inventor: NONAKA IKUMITSU
IPC: H01J9/233
Filed: 1980-12-12
Abstract: PURPOSE:To obtain a target with a decreased dark-current value by preserving a base plate with relative humidity less than the prescribed level and a nesa film set on the base plate before a germanium-oxide film is formed over the base plate and the nesa film, and followed by the formation of a photoconductive layer either straight on the germanium-oxide film or with a cerium-oxide film interposed between the germanium-oxide film and the photoconductive layer. CONSTITUTION:A nesa film 2 and a germanium-oxide film 3 are formed over a glass base-plate 1, in that order. Next, a photoconductive layer 5 is formed through vacuum evaporation either straight on the film 3 or with a thin conductive layer 4 made of a composite material which comprises not less than one of zinc selenide, zinc oxide and cerium oxide, thus a target being constituted. Before forming the film 3, the base plate 1 and the nesa film 2 should be preserved in a place where relative humidity is below 10%. As a result, no adhesive moisture is allowed to occur between the nesa film 2 and the film 3, and the deterioration of the hole injection- proof effect which is caused from the nesa-film side is prevented. Consequently, a target with an effectively small value of dark current can be obtained.

Title: Color toner and color electrophotographic method
Inventor: HIROTA NORIAKI
IPC: G03G9/09
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To control the electrostatic chargeability of each of yellow, magenta, cyan and black toners due to the surface state and the surface state difference among the color toners due to a way of cracking in comminution and to stably output a high grade color image by specifying the difference between the maximum and minimum coefficients of dynamic friction of each of the color toners. SOLUTION: When the coefficients of dynamic friction of yellow, magenta, cyan and black toners each consisting essentially of a bonding resin, a colorant and an additive are represented by YF, MF, CF and BF, respectively, the relation of the expression max(YF, MF, CF, BF)-min(YF, MF, CF, BF)<=0.2 [where max() shows the maximum value in () and min () shows the minimum value in ()] is satisfied. The expression shows the difference in the coefficient of dynamic friction among the color toners. When the difference increases, the toners are made different from one another in dynamic separability from a photoreceptor or an interim transfer body, have different transfer behaviors in a transfer part and cannot attain accurate color reproduction.
