There is provided a plasma display device capable of high luminous efficacy and stable driving for displaying images at various image display load factors. The plasma display device performs the sustain discharge for a light-emission display, and is configured to apply a sustain pulse voltage between a sustain electrode pair in a respective one of the plural discharge cells to generate a sustain discharge in a respective one of the following operating modes selected based upon use of the plasma display device: (a) generating a pre-discharge and then a main discharge; (b) generating a main discharge without a pre-discharge preceding the main discharge; and (c) switching between the mode (a) and the mode (b). The sustain voltage waveforms are used which compensate for an increase in voltage drop due to an increase in discharge current when the image display load factor is excessively increased.

The invention relates to an optical disc device and a control method for the optical disc device. The presence of defects on an optical disc is confirmed by, based on the result of detecting a return light corresponding to a sub-beam spot used for tracking control, which is formed on the preceding side with respect to scan of a main beam spot, suppressing changes in signal level of the light detection result caused upon boosting of the laser power of a laser beam. Also, whether data can be correctly reproduced is determined by, based on the result of detecting a return light corresponding to a sub-beam spot used for tracking control, which is formed on the succeeding side with respect to scan of the main beam spot, suppressing changes in signal level caused upon writing of the data. Therefore, whether data can be correctly reproduced can be confirmed with a simple construction while effectively avoiding a reduction of the data transfer rate.

A failed manifold pressure sensor is identified in a control apparatus having two manifold pressure detecting systems as a failsafe. A first comparing unit outputs an abnormal signal when a difference ΔP between manifold pressures PMa and PMb detected respectively by two sensors is larger than a threshold value DP. A manifold pressure estimating unit estimates the manifold pressure from the engine revolution Ne, a throttle opening PLP, and an atmospheric pressure PAa. The difference calculating unit calculates a difference ΔPMb between the detected manifold pressure PMb and the estimated manifold pressure PMcal. The difference calculating unit calculates a difference ΔPMa between the detected manifold pressure PMa and the estimated manifold pressure PMcal. A second comparing unit compares the difference ΔPMa and the difference ΔPMb in response to the aforementioned abnormal signal. The failed manifold pressure sensor is specified according to which one of the difference ΔPMa and the difference ΔPMb is larger.

A digital subscriber line communicating system for communicating between a transmitting side and a receiving side through a communication line, comprising a hyperframe counter for periodically counting a predetermined number of continuous transmitting data symbols constituting a hyperframe synchronized with a timing signal, and a decoder for discriminating, based on the count value of the hyperframe counter, whether a transmitting data symbol belongs to a FEXTR or a NEXTR.A sequencer is provided for initializing the status during an initialization period before starting usual communication. The initialization period includes an activation and acknowledgement sequence, a transceiver training sequence, a channel analysis sequence, and an exchange sequence. According to a single bitmap mode, the initialization is carried out by transmitting modulated symbols through only inside of said sliding window. According to a dual bitmap mode, the initialization except for an S/N measuring sequence in the channel analysis sequence is carried out by transmitting modulated symbols through only inside of said sliding window, and the S/N measuring sequence is carried out by transmitting modulated symbols through both inside and outside of said sliding window.
