Abstract:
An electroconductive article is disclosed, which comprises a polar group-containing high polymeric substrate, and an electroconductive layer of cupric sulfide formed therein and is produced by immersing the polar group-containing high polymeric substrate in an aqueous solution containing a bivalent copper compound and a reducing agent or an aqueous solution containing a monovalent copper compound, and at the same time or subsequently treating it in a solution of a sulfur releasable substance.
Abstract:
A novel method and apparatus for electrophotography is disclosed which enables selection the mode of image formation among positive-positive, negative-positive and combinations thereof without any need of changing the polarity of developing toner. The present invention is made on the basis of a known electrophotographic system in which a photosensitive member composed of essentially an electrically conductive substrate, a photoconductive substance layer and an insulating surface layer and which comprises the steps of charging the insulating surface layer, image-wise exposing it to light so as to form a first image almost simultaneously with or some time after the charging step, subjecting it to corona discharge with nearly simultaneous image-wise exposure so as to form a second image and uniformly exposing the whole surface of the photosensitive medium to light so as to form an electrostatic latent image corresponding to a composite image resulting from the first and second images. According to the invention the first and second images to be formed are identical with each other and either one of the two images is selectively exposed to obtain the desired image.

Abstract:
An overlay recording device for recording first information and second information in a superimposed mode on a recording medium by reading out the first information from storage in a first memory and the second information from storage in a second memory, thereafter converting the respective first and second information so read out into first and second dot signals, modulating a beam with logic outputs of the first and second dot signals to thereby form a beam modulated by the first information and the second information, and scanning the recording medium with the modulated beam.
Abstract:
Control apparatus for controlling the quantity of light includes a light emitting device for emitting light in response to a driving signal applied thereto, a photodetector for receiving the light to produce a detection signal representative of the quantity of the light received, a comparator for comparing the detection signal with a reference signal, a circuit for applying a recording signal to the light emitting device, a start control responsive to an instruction signal which causes the control apparatus to start controlling the quantity of light during the time period when no recording signal is applied, an incrementing device for incrementing the driving signal to be applied to the light emitting device in response to the instruction signal received, and a stopping circuit for stopping the incrementing in response to the comparator to hold a count which is contained in the incrementing device when stopping, until the instruction signal is subsequently applied. The light emitting device may include an array of light emitting elements.
Abstract:
A scanning method for scanning a scanned surface simultaneously by a plurality of beam spots in which each beam spot passing through light beam detecting means provided outside the requisite scanned area of the scanned surface, to detect the time when each beam spot begins the scanning of the requisite scanned area, is focused with respect to the scanning direction of the beam spot and defocused with respect to a direction orthogonal to the scanning direction.
