摘要： In a control system for an information recording laser beam, an intensity of a laser beam is varied in a predetermined variation pattern during each of sequential one-pixel periods. The laser beam is periodically activated and deactivated in synchronism with a change of the one-pixel periods. A duration of the activating the laser beam within each of the one-pixel periods is controlled in accordance with a density of each of pixels of an image to be recorded.

摘要： An output apparatus for printing a proof sheet and making a planographic printing plate, comprising a printing image data generating means for producing the digital data of a plurality of different color images corresponding to a predetermined number of colors obtained by the color separation of the image data of an original to be printed; a proof sheet outputting means for sequentially forming a screened dot image of each color by using each color toner based on the printing image data derived from said printing image generating means; a planographic printing plate output means for forming a screened dot image of each color by using one recording medium for each color and the oil affinitive toner of each color based on the digital data of each color generated by said printing image data generating means. By providing further a means for compensating for the difference in characteristics between the printing of a proof sheet and the planographic printing (actual printing), one output apparatus can output both the data for printing a proof sheet and the data of the actual printing (the planographic printing).

摘要： A charge latent image is formed on a recording medium in response to information and a reference pattern so that the information and the reference pattern are recorded on the recording medium. During a reproducing process, the information is read out from the recording medium and an information signal representing the readout information is generated. In addition, the reference pattern is read out from the recording medium and a reference signal representing the reference pattern is generated. The information is demodulated from the information signal. The reference signal is used in the demodulation of the information from the information signal.

摘要： A voltage is electrostatically induced at a sensing device in correspondence with a surface potential of a measured object. In the case where the sensing device uses a field effect transistor in transferring detected information, there are some factors decreasing the accuracy of detection. Various new arrangements prevent such decreases in the accuracy of detection. In the case of the surface potential of the measured object corresponds to an optical image, new arrangements ensure accurate detection of the optical image. In some cases, color component signals are obtained on the basis of a detection signal.
