摘要： Disclosed is a magnetographic apparatus wherein a large number of copies of the same picture is produced by repeatedly using a recording drum on which a latent image of the picture is recorded, which apparatus is different from a conventional magnetographic apparatus wherein a sequence of processes consisting of a latent image recording process, a process of developing the image and a process of transferring the image is effected for production of each copy. Further disclosed herein are structural elements of a magnetographic apparatus which are suitable for producing a large number of copies of the same picture by repeatedly using a recording drum as described above.

摘要： A digital function fitter includes an UP/DOWN counter, a clock pulse generator, a counter counting the number of the clock pulses, a plurality of gate circuits and a Multiplexer for supplying selectively the digital outputs of the gate circuits to the UP/DOWN counter. A non-linear digital input is applied to the up-terminal of the UP/DOWN counter and the digital outputs from the gate circuits are applied to the down-terminal of the UP/DOWN counter. A linearized digital value can be obtained from the counter when the number of the non-linear digital input coincides with the digital outputs from the gate circuits.

摘要： A method for forming an electrostatic image on a photosensitive member having a photoconductive layer bonded to a conductive layer by applying a charge of one polarity to the photoconductive layer, and then exposing the photoconductive layer to a pattern of image radiation to form an electrostatic latent image. The photoconductive layer is then exposed to blanket radiation and the electrostatic latent image is then developed by using a liquid developer having the same polarity as the charge applied to the photoconductive layer to form a visual image in a relatively shortened exposure time.
