Title: Manufacture of electrophotographic sensitive body
Inventor: MIZUKAMI HIROYUKI
IPC: G03G5/082
Filed: 1986-05-30
Abstract: PURPOSE:To prevent abnormal growth in a photoconductive layer and to obtain a photosensitive body free from image noise and good in characteristics by shifting the region in which the abnormal growth occurs downstream in the gas flow direction farther from a substrate and adjusting the ratio of the flow rates of silane and H2. CONSTITUTION:The photosensitive layer (photoconductive layer) made of amorphous silicon is formed by the plasma CVD method, and at that time, the mixing ratio of H2 to monosilane (SiH4) of the gas mixture as material gases is adjusted so as to shift the occurrence region of the abnormal growth to the downstream side of the substrate. The adjustment of this ratio to the following proper range: 0.1 <= (H2 to SiH4 ratio) < 2 permits the film forming region to avoid the occurrence region of the abnormal growth and the photoconductive layer free from abnormal growth and good in film characteristics to be formed. If said H2 to SiH4 ratio exceeds 2, the growth velocity lowers.

Abstract: PURPOSE:To form an optically anisotropic substance in a light transmissive piezoelectric porcelain by applying DC or AC voltage between partial electrodes formed in confronted manner on the main plane surfaces of the front and rear of a thin light transmissive piezoelectric porcelain. CONSTITUTION:Partial electrodes are formed, for example, in rectangular shapes 7, 7' or circular shapes 8, 8' in confronted manner on the front and rear surraces of the main plane surfaces of a thin light transmissive piezoelectric porcelain 6. DC or AC voltage is so applied between the confronted electrodes 7 and 7' or 8 and 8' that the polarizing electric field may, for example, become Ep>=10kV/cm. The thickness t of the porcelain 6 is much smaller than the distance d between the electrodes as applied on one surface in the conventional manner, and the applied voltage can be lowered. The values of the double refraction of the electrode portion and the nonelectrode portion are different symbols. Thus, the nonelectrode portion can be effectively polarized, and can also be formed in optically anisotropic substance.

Filed: 1990-05-16
Abstract: PURPOSE:To considerably increase a reverse dielectric strength and expand the operation range by removing a portion positioned below a wiring layer formed in the upper portion of a substrate in such a manner as traverse the upper portion of a third diffusion layer. CONSTITUTION:A collector diffusion layer 7 serving as a third diffusion layer 3 is formed into a substantially U shape by removing the central portion at one side on the right side thereof.
