Abstract: A color copier includes exposure light source (3) for exposing an original document with red, blue, and green light, on a photosensitive film (6) having a substrate and an ink coating which includes ink particles of multiple colors carried on the substrate, and on which a reproduc­tion of the original document is formed, in response to the light exposure, through a reaction of ink particles of the color which corresponds to the wavelength of the light reflected from the original document. The color copier further includes a lightproof film case (9) for storing the photosensitive film (6), an image forming lens (4) for forming an image of the original document on the photosensitive film by focusing the reflected light; a copy paper feeder (21, 22) for feeding a copy paper; fixer (5 and 15) for fixing the image formed on said photosensitive film on the copy paper; a separation claw (24) which separates the photosensitive film from the copy paper after the fixing of the image; a film take-up shaft (32) for winding thereon the photosensitive film. The film take-up shaft is located downstream from the separation claw in the direction of paper transport, and is formed with an insertion slot for inserting a leading edge of the photosensitive film.

Abstract: Besides an input switched capacitor (14) for sampling an input analog signal into output electric charges, an oversampling analog-to-digital converter comprises an additional switched capacitor (47) for sampling, into additional electric charges in synchronism with the input switched capacitor, controlled electric charges produced by a capacitor array (24) which is coupled to a reference voltage source (23) and is controlled by a predetermined number of control signals produced by a control logic (22) in response to an output digital signal. A summing circuit delivers the output and the additional electric charges to an integrator (15) connected to a quantizer (21) which produces a quantized signal substantially identical with the digital signal. Preferably, the summing circuit comprises a connecting switch (49) for supplying the output and the additional electric charges to the integrator in synchronism with the input and the additional switched capacitors. A switch array (25) is controlled by the control signals to make the capacitor array produce the controlled electric charges.

Abstract: An adaptive single-bit encoder and decoder has its adaptive function determined by dynamically dividing the message frequency band into delta-sigma and delta modulation regimes of operation. In a practical embodiment this is accomplished by varying the corner frequency of a variable-frequency low-pass filter (14, 14′) in a leaky integrator so that below the corner frequency the operation is that of delta-sigma modulation and above the corner frequency the operation is that of delta modulation. An adaptation control circuit (18, 18′) removes the clock signal component from the encoded bit stream to provide an analog signal representative of bit stream information or loading for use in generating the control signal. The analog signal is peak rectified (22, 22′), smoothed (24, 24′), and (optionally) non-linearly processed (26, 26′) to provide the control signal.

Abstract: A transmission grating is used to reduce chromatic aberration in an optical system, wherein the system's chromatic dispersion is offset and substantially canceled by the grating's diffraction-induced dispersion. The grating comprises a Fresnel-type pattern of microscopic facets molded directly into one of the system's refractive optical surfaces. The facets would typically have a profile height of around 4 . 10 -5  inch and a profile width of at least 10- 3  inch. In its primary intended application, the invention would function to improve the optical performance of a Fresnel lens used to concentrate direct sunlight into a piped daylight illumination system. For this application, about a ten-fold reduction in chromtic dispersion would be attained with only about a 2% loss in optical efficiency.
