摘要： A transmitting method of digital data whereby information data can be reproduced at a high precision. In order to retain digital data in sectors comprising a plurality of sync frames and sequentially transmit, the sync frame is comprised of the sync signal and the run length limited code which satisfies the limitations of the minimum run length and the maximum run length, and the sync signal includes the sync pattern constituted by a bit pattern of a run length that is longer than the maximum run length by only 3T and addition bit patterns which are arranged before and after the bit pattern and each of which has a run length that is longer than the minimum run length. The sync signal includes a specific code which indicates a position in the sector and which enables the DC control to be performed.

摘要： A liquid crystal display device is proposed which has a substrate (12) having electrodes (48) corresponding to the display picture elements, liquid crystal (22) arranged on the substrate (10) through a dielectric mirror (14), and a transparent electrode (18) arranged on liquid crystal (22) and applying electricfields to the liquid crystal (22) for each picture element through the respective electrodes (48) on the substrate (12). The substrate (12) has memory cells which are capable of storing data and of becoming electrically conductive, this conductive condition being determined and sustained based on the contents of the stored data. The electric fields are applied to the liquid crystal (22)throughthese memory cells.

摘要： n automatic equalizer comprises a transversal filter (2) for receiving an input signal (X(t)) to be equalized and having adjustable tap gains, a circuit (3) connected to receive an output signal of the transversal filter and the input signal to be equalized to produce an equalized output signal (Y(t)), a distortion detect circuit (5) for detecting a distortion component included in the output signal, a tap gain correct circuit (6) connected to receive a distortion detect signal from the distortion detect circuit to produce tap gain correct signals, and a tap gain hold circuit (7) responsive to the tap gain correct signals to correct the tap gains of the transversal filter and hold the corrected tap gains. In order to eliminate the influence of DC offset component at the output of the distortion detect circuit on the signal equalization, a polarity inverting circuit (8, 9, 10, 11) is provided for synchronously and periodically inverting the polarity of a signal component included in the output signal of the distortion detect circuit and the polarity of the tap gain correct signals.
