    摘要： Each memory cell of the memory array has a latch circuit, such as a pair of cross-connected CMOS inverters, for storing information, a first switch MOSFET whose gate is connected with a word line, and a second switch MOSFET which is connected in series with the first switch MOSFET and the gate of which is connected with the output terminal of the latch circuit. The first and second switch MOSFETs are coupled between the data line and a terminal supplied with a first power source voltage level, such as reference ground potential. Such memory cells are disposed at intersections of a plurality of data lines and a plurality of word lines. One of the plurality of data lines is connected with a common data line through a column switch which is alternatively brought into an ON state. Prior to a reading operation, the data lines are precharged to the first power-source voltage level, or ground potential, and the common data line is precharged to a second power-source voltage level, such as the supply voltage of the memory.

    摘要： A manual image scanning system is operative to read image data of figures or letters depicted on a sheet of paper based on manual operation to input them to a personal computer for data processing. The manual image scanning system comprises a data tablet or a digitizer in which magnetostriction pulses propagate, the data tablet being adapted so that a sheet of paper on which a figure is drawn is placed thereon, and a compact manual image scanner adapted to be manually movably placed on the data tablet, the manual image scanner having a first function to recognize the figure drawn on the paper to produce data indicative of image of the figure, and a second function to sense a position of the scanner to produce data indicative of the position of the scanner. The scanning system further comprises high speed image processing circuitry responsive to the image data and the position data from the scanner to compute coordinates of the scanner on the data tablet, thereby recognizing which portion of the data tablet the image data corresponds to. Thus, this system can sufficiently exhibit features provided by the data tablet and the optical figure recognition device.

    摘要： A demodulator responsive to baseband signals from a coherent detector having an automatic equalizer part for supplying equalized signals to derive transmitted datum and a phase control part responsive to equalized signals. The automatic equalizer part includes a delay member with a plurality of taps and variable attenuators connected to the respective taps of the delay member. The phase control part is provided with a phase shift circuit such as a coherent detector and a control circuit for detecting phase variation components of equalized signals. Further, the control circuit feeds phase variation components detected to the phase shift circuit and simultaneously supplies error signals which are dependent on phase variation components to the respective variable attenuators of the automatic equalizer.

    摘要： An equalizer comprises a tapped delay line of a transversal filter and first equalizing means responsive to a short pseudo-noise train supplied thereto for adjusting tap gains so as to make the transversal filter output signals simulate a pseudo-noise train generated at the receiver with the pulse pattern of the supplied pseudo-noise train. Larger ones, in absolute values, of the adjusted gains are placed at the center of the delay line. Responsive to a subsequently supplied long pseudo-noise train, second equalizing means self-adaptively adjusts all tap gains. The delay line preferably comprises delay units, each for a half of a common clock interval of the supplied pseudo-noise trains and data signals.
