摘要： An A.C. corona discharging device for use in the process in which discharge and exposure are accomplished contemporaneously has insulating members disposed so as to surround the discharge wire or electrode and define the opening for projecting the image of an original. The potential gradient is increased, the discharge efficiency is improved and the flow of useless current which heretofore traveled through the shielding electrode is not encountered.

摘要： A process and apparatus for forming an electrostatic image on a photosensitive plate having a conductive base, a photoconductive layer overlying the base and exhibiting p-type or n-type semiconductivity, and an insulative layer overlying the photoconductive layer. The photosensitive plate is characterized in having carrier charge of a polarity corresponding to the conductivity type of the photoconductive layer injectable from the conductive base into the photoconductive layer and bound in the region of the interface between the insulative and photoconductive layers. The conductive base is transparent to activating light and the insulative layer is opaque to the activating light. A first charge of a polarity opposite to the conductivity type of the photoconductive layer is applied onto the insulative layer to inject and bind carrier charge in the region of the interface between the insulative and photoconductive layers. Then, the photoconductive layer is exposed to a pattern of activating image light by projecting the image light through the transparent conductive base while a corona discharge is applied onto the insulative layer. Thereafter, the photoconductive layer is exposed to activating light through the transparent conductive base to discharge bound carrier charge remaining in the region of the interface and form a high constrast electrostatic image.
摘要翻译：一种用于在具有导电基底，覆盖在基底上并具有p型或n型半导电性的光电导层和覆盖在光电导层上的绝缘层的感光板上形成静电图像的方法和装置。感光板的特征在于具有对应于从导电基底注入到光电导层中的光电导层的导电类型的极性的载流子电荷并且在绝缘和光电导层之间的界面区域中结合。导电基体对于激活光是透明的，并且绝缘层对于激活光是不透明的。将与光电导层的导电类型相反的极性的第一电荷施加到绝缘层上，以在绝缘层和光电导层之间的界面区域注入和结合载流子电荷。然后，通过在将绝缘层上施加电晕放电的同时将图像光投影穿过透明导电基体，使感光层暴露于激活图像光的图案。此后，光电导层通过透明导电基底暴露于活化光，以排出残留在界面区域中的结合载体电荷并形成高约束静电图像。

摘要： A process for forming an electrostatic image on a plate having a conductive base, a photoconductive layer exhibiting p-type or n-type semiconductivity and a covering insulative layer, said photosensitive plate being characterized in having carrier charge of a polarity corresponding to the conductivity type of said photoconductive layer injectable from said conductive base into said photoconductive layer and bound in the region of the interface between said insulative and photoconductive layers, wherein the covering insulative layer is initially charged with a polarity opposite to the conductivity type of said photoconductive layer to inject and bind charge carrier in the region of the interface between said insulative photoconductive layers, then the photoconductive layer is exposed to a pattern of image light, while a corona discharge of a polarity opposite to the first charge is applied onto the insulative layer, and then the photoconductive layer is exposed to activating light to discharge bound carrier charge remaining in the region of the interface between said insulating and photoconductive layers and form a high contrast electrostatic image.
