    摘要: A digital communication device includes: a modulator having encoding means for converting two-dimensional digital information signal into a three-dimensional signal and phase modulation means for modifying the carrier phase in according to the three-dimensional signal; and a demodulator having phase demodulation means for detecting information on the three-dimensional signal from the received phase-modulated wave and demodulation means for deciding the two-dimensional digital information from the information on the three-dimensional signal. The digital communication device has a bit error ratio and an occupied radio band width equivalent to a digital communication device using the conventional QPSK or π /4 shift QPSK and the error correction method and greatly improves the amplitude fluctuation. Moreover, the digital communication device can transmit a signal with a narrower occupied frequency band width while maintaining the same constant envelope characteristic as the GMSK using the conventional error correction code.

    摘要: A black perylene pigment obtained by burning at least one compound selected among diimide derivatives of perylenetetracarboxylic acid and diimide derivatives of perylenediiminodicarboxylic acid under vacuum or in an inert gas atmosphere at 200 to 600°C. It is excellent not only in blackness but in heat resistance and weatherability, has high resistance, and is highly safe.
