摘要： An RF transmission circuit, complex digital synthesizer and MRI apparatus are intended to enhance the stability of signal quantity and reduce the cost, wherein a complex digital synthesizer generates reference carrier frequency signal data directly in the digital domain, RF envelope mixers combine the resulting data and RF envelope signal data in the digital domain, and a digital frequency up-converter up-converts the resulting signal data in the digital domain and converts into an analog RF pulse signal.

摘要： An electromagnetic relay is provided with an iron core (50) which has a virtually J-letter shape on a plan view with one end serving as a support-receiving portion (51) and the other end serving as a magnetic pole portion (52), and a movable iron member (60) which is supported by a movable contact member (70) attached to a corner thereof, and has a virtually L-letter shape on a plan view with one end (61) being supported on the support-receiving portion (51) of the iron core (50) so as to freely pivot thereon and an adsorb portion (62) that is the other end being allowed to face the magnetic pole portion (52) of the iron core (50) so as to be adsorbed thereon. The objective of the present invention is to provide an inexpensive electromagnetic relay which is less susceptible to deviations in the adsorb portion of the movable iron member that comes into contact with and separates from the magnetic pole portion of the iron core, and has stable operation characteristics.

摘要： For the proper delivery of digital data D_AD from a fast A/D converter to a digital signal process section, the digital data is stored in a dual-clock-synchronous FIFO by being timed to the output of digital data from the fast A/D converter (at the timing based on a data ready signal DATA_RDY). The dual-clock-synchronous FIFO reads out digital data D_FIFO and delivers to the digital signal process section by being timed to the operation of the digital signal process section (at the timing based on a clock signal CLK_DIG for a digital signal process).
