    Abstract: A technology effective for improving the luminous efficiency, lifetime, and color temperature of a PDP having phosphor layers of three colors is disclosed. A PDP comprises a plurality of narrow tubes (60) arrayed on a substrate (51). In each narrow tube (60), one of phosphor layers (61R; 61B, 61G) is formed and a discharge gas is contained. The compositions and pressures of the discharge gases are set within appropriate ranges respectively corresponding to the phosphor layers (61R, 61B, 61G). Consequently, the PDP can have a lengthened life-time and an improved luminous efficiency. Reductions of variation in breakdown voltage and adjustment of color temperature are also possible with this constitution.

    Abstract: The present invention aims to provide a PDP apparatus and a driving method for the same which can improve display quality by reducing a peak value of a discharge current flowing in scan and sustain electrodes in a sustain period, without an increase in manufacturing cost. This is achieved as follows. A driving unit 20 applies a sustain data pulse 320 to a plurality of third electrodes in a sustain period T3. Here, a voltage waveform of the sustain data pulse 320 starts to rise after a voltage of each of pulses 300 and 310 applied to a pair of a scan electrode SCN and a sustain electrode SUS reaches a predetermined level. Furthermore, the sustain data pulse 320 rises at a different timing at least from a sustain data pulse 320 applied to an adjacent data electrode.

    Abstract: A system for simultaneously transmitting over the same voice circuit a voice signal and input information other than the voice. First and second sine-wave signals which do not bear any harmonic relation to each other in the band of the voice circuit are simultaneously frequency modulated by the input information, and the modulated outputs are superimposed on the voice signal and transmitted. On the receiving side, the pitch frequency of the voice signal is extracted from the received signal, and the pitch frequency and its integral multiples are removed from the received signal to remove a voice component. At this time, at least one of the first and second sine-wave signals is detected. One of these detected outputs is made to have the same frequency as the other frequency. The converted frequency and the detected frequency are demodulated to obtain the original input information.

    Abstract: A speech signal fundamental period extractor which receives a residual value signal from a speech analyzer, such as one using autocorrelators. The residual value signal is first passed through a filter to remove the high-frequency components. Then the signal is quantized to obtain low-bit quantization of the residual value. The output from the quantizer is then sent to an autocorrelator to obtain the correlation coefficient and the fundamental period is extracted by selecting the position of a maximum correlation coefficient. This provides more accurate results and permits the use of low-speed elements and a reduction of components.

    Abstract: A sustain pulse generation circuit of a plasma display device generates and switches a first sustain pulse for causing light emission having double peaks, a second sustain pulse having a falling edge steeper than that of the first sustain pulse, and a third sustain pulse having a rising edge and a falling edge steeper than those of the first sustain pulse and causing light emission having a single peak. The second sustain pulse or the third sustain pulse is generated immediately before the third sustain pulse. The first sustain pulse is generated immediately before the second sustain pulse. Provided between the second sustain pulse and the third sustain pulse and between the third sustain pulses is a first overlap period in which a time period for causing the corresponding sustain pulse to rise is overlapped with a time period for causing the corresponding sustain pulse to fall.
