Abstract: <P>PROBLEM TO BE SOLVED: To reduce required transmission power of the entire system and to reduce a circuit scale when performing broadcast communication or multiplex transmission.  <P>SOLUTION: When applying space division multiplex, only one system of semiconductor chips 103_1 and 203_1 is turned to an ASK method and an injection locking method is adopted in the system. Reproduction carrier signals are generated on the basis of reception signals in the reception side local oscillation part 8404 of the semiconductor chip 203_1, and the reception signals are demodulated by synchronous detection in a frequency mixing part 8402. The entire remaining system is turned to a BPSK method and the injection locking method is not adopted. Instead, on the basis of the reproduction carrier signals generated in the reception side local oscillation part 8404 of the semiconductor chip 203_1, the reception signals are demodulated by the synchronous detection in the respective frequency mixing parts 8402. The required transmission power as the entire system is reduced compared to the case of adopting the ASK method in all the systems. The circuit scale as the entire system is reduced compared to the case of having an injection locking circuit in all the systems.  <P>COPYRIGHT: (C)2011,JPO&INPIT

The discharge of the liquid is performed considering the acquired head stop time. In this manner, when the jet head is reciprocated after the discharge of the liquid, it is considered that there is no progress in the sedimentation of the liquid in the liquid passage in comparison with the case of no reciprocating at all, and the amount of the liquid to be discharged can be reduced without discharging the liquid for eliminating the sedimentation more than necessary.  <P>COPYRIGHT: (C)2011,JPO&INPIT
