The carbon dioxide membrane separation system in a coal gasification process contains introduction of a mixed gas of hydrogen (H2) and carbon dioxide (CO2) in a high temperature and high pressure condition generated through water gas shift reaction from a water gas shift reaction furnace, while maintaining the temperature and pressure condition, to a zeolite membrane module containing a zeolite membrane for removing carbon dioxide, thereby removing carbon dioxide and generating a fuel gas rich in hydrogen. The fuel gas rich in hydrogen in a high temperature and high pressure condition discharged from the zeolite membrane module is fed to a gas turbine of the power generation facility while maintaining the temperature and pressure condition.

A communication system includes a modulating circuit to increase the amount of information to be transmitted, a transmitting apparatus capable of easily generating a desired waveform even for any very short wavelets, a receiving apparatus capable of easily separating wavelets even if the intervals thereof are narrow. The modulating circuit includes clock generating, transmission signal generating, control signal generating, delay and wavelet generating parts. The clock generating part generates a clock signal at predetermined time interval “Tp”. The transmission signal generating part generates a transmission signal at interval “Tp”. The control signal generating part outputs a control signal of a predetermined duration based on the clock signal. The delay part generates the control signal as a delay signal that has been delayed by a delay amount based on the transmission signal. The wavelet generating part generates a wavelet at the generation timing of the delay signal.

摘要:
A wireless communication method, a radio transmitter apparatus and a radio receiver apparatus wherein a signal sequence, which is used in a reception process using a first modulation scheme and can be generated from a signal sequence prepared for a reception process and used in a second modulation scheme, is employed, thereby achieving a performance to a similar extent to the reception process performance using the second modulation scheme. A radio transmitter apparatus (20) uses a first modulation scheme (e.g., OOK modulation scheme) to sequentially transmit, as a first sequence, both a sub-sequence a1(n), which is identical with a second sequence a(n) designed for use in a second modulation scheme (e.g., BPSK modulation scheme), and a sub-sequence a2(n), the bits of which are reverse to those of the second sequence a(n), in a time division manner. A radio receiver apparatus (30) detects the sub-sequence a1(n) and sub-sequence a2(n) in a received signal to send the detection result to the following stage for a signal processing.

A radio receiving apparatus and a radio receiving method wherein synchronization is established at a high speed with high reliability. An IR receiver (100) includes a synchronization establishing unit (120), which comprises a correlator (154) that correlates a received pulse signal with a first pulse template; a first synchronization control means including a threshold value determining part (156) that determines, based on a result of that correlation, whether a first synchronization (coarse synchronization) is established and that shifts the correlation timing between the received pulse signal and the first pulse template when the first synchronization has not been established; a correlator (162) that correlates the correlation result of the first correlating means with a second shorter pulse template after establishment of the first synchronization; and a second synchronization control means including a threshold value determining part (164) that determines, based on a result of this correlation, whether a second synchronization (fine synchronization) is established and that shifts the correlation timing between the correlation result of the correlator (154) and the second pulse template when the second synchronization has not been established and that outputs timing information of establishment of the second synchronization when the second synchronization is established.
