    摘要： A synchronous separation circuit used in a television video circuit for generating a horizontal synchronizing signal and a vertical synchronizing signal from a composite synchronizing signal has: a unit for generating a clock signal used as a reference signal and having a frequency higher than the frequency of the horizontal synchronizing signal; a unit for counting the clock signal from a front edge of a pulse contained in the composite synchronizing signal; a unit for obtaining a horizontal synchronous separation and for determining a counting term and outputting the horizontal synchronizing signal after the counting unit counts from the front edge of the horizontal synchronizing signal to a predetermined number; and a unit for obtaining a vertical synchronous separation and for latching the composite synchronizing signal based on an output of the counting unit, separate the vertical synchronizing signal from the composite synchronizing signal.

    摘要： A plasma display panel and driving method thereof perform addressing at a high speed and a low voltage without deteriorating contrast. Priming electrodes forming priming cells are located outside but adjacent a display area. Glow occurring in the priming cells is intercepted. When priming discharge is induced at a reset step, voltages lower than a discharge start voltage are applied to first (X) and second (Y) electrodes and third (address) electrodes respectively. Despite the voltages being lower than the discharge start voltage, once discharge is induced in the priming cells, discharge starts in adjoining cells. The discharge then spreads successively over all the cells, thus inducing discharge in all the cells. Consequently, wall charge is produced in all the cells.

    摘要： A semiconductor delay circuit device comprises a pair of transistors of the same conduction type having source regions that are arranged adjacent to each other and facing each other, and a substrate contact diffusion region whose conduction type is opposite to that of the source regions. The substrate contact diffusion region extends between the source regions. Therefore, the source regions of the transistors do not influence each other.

    摘要： Noise pulses having both polarities which are superposed on an input signal having a binary state of H/L levels forming a rectangular waveform, are suppressed or eliminated before transferring the input signal to an output stage. A noise pulse suppressing circuit is provided which comprises a latch circuit, a counter circuit, and a logic circuit including NAND gates and INVERTERs. For the latch circuit and the counter circuit, D-type flip-flops are also utilized. The input signal is inputted to a data input terminal of a flip-flop of the latch circuit and outputted from the data output terminal thereof. The latch circuits are triggered by a pulse signal applied to a clock terminal thereof. The above triggering pulse signal is generated by the counter circuit and the logic circuit, and it has a short pulse waveform responding to the input signal but delayed. No pulse in the output is produced which corresponds to the noise pulses in the input signal.
