    摘要: A facsimile communication system includes a transmitter 10 for transmitting facsimile information, the facsimile information including a plurality of document formats each having a different address; and a receiver for receiving facsimile information, including a memory 20 for storing the document format in digital data form and for reading out stored digital data. In addition there is provided a transmitter 21, 24 for transmitting alpha-numeric data, including apparatus for respectively identifying a plurality of unique portions of alpha-numeric data with an address corresponding to a selected document format address; and a receiver for receiving the alpha-numeric data. The latter receiver includes apparatus for integrating the identified portions of data with the data of the correspondingly addressed document format. A printer then prints the integrated data in document form.

    摘要: In the processing of light-sensitive media, for example lithographic printing plates, the active components of the developer are used up and need replenishment, particularly when silver halide or similar technology is involved. The modulation signal of a laser used to expose the light-sensitive media is integrated to provide a signal indicative of the exposed image area to be developed and this signal is used to control the addition of replenishment material. Replenishment required to overcome the degradation of the active components with time may also be incorporated. In a preferred embodiment of a replenishment control circuit a laser beam modulator 31 supplies a modulation signal to an integrator comprising a high output frequency sampler 32, a counter 33 and a laser-on counter 34a. A developer circulating pump 35 and a replenishment pump 36 are controlled by a microprocessor 34 which contains the laser-on counter 34a and a replenishment dose required counter 34c fed by the counter 34a and a time base generator 34b which provides a purely time-dependent component of the replenishment required count. A replenishment dose control counter 34d controls operation of the pumps 35 and 36 in dependence upon the content of the dose required counter 34c.
