摘要： If a total number of specific RF tags is too large, many RF tags respond at a time. Therefore a problem occurs that an interrogator cannot receive information from the RF tags. A first invention relates to an RF tag. The RF tag includes an interrogator signal receiving section for receiving an interrogator signal from an interrogator, a synchronizing signal generating section for generating a synchronizing signal from the received interrogator signal, a response information obtaining section for obtaining response information according to the interrogator signal, a spread-code modulating section for modulating the response information with a spreading code and obtaining the spread-code modulated response information, and a transmitting section for transmitting the response signal that contains the spread-code modulated response information in a data area at a random transmission interval in synchronism with the synchronizing signal.

摘要： An inquiry device in the conventional non-contact IC card system has a problem that the electronic circuit size is large and complicated, requiring a very expensive high frequency part to increase the cost. In order to solve this problem, a part of the signal processing function realized by an electronic circuit in an inquiry device is performed by a receiving antenna and a receiving high frequency amplifier, thereby significantly reducing the electronic circuit size. The inquiry device includes a carrier oscillator connected to a transmitting mixer, a receiver section, and a receiving high frequency amplifier for amplifying the receiving high frequency received by the receiver section. The inquiry device in the non-contact IC card system is characterized in that a carrier generated by the carrier oscillator is interference-input to the receiving high frequency amplifier so as to modulate the receiving high frequency. As compared to the conventional method, the power distributor and the frequency converter can be omitted.

摘要： A communication system includes a transmitter that applies an electric field, obtained by modulating an information signal for wideband communication, to a transmission medium. The transmitter includes a transmission electrode, a transmission circuit that outputs the information signal for the wideband communication, and a first band controller that controls a band of the information signal for the wideband communication. When the transmission medium is in contact with the transmission electrode and the transmission medium and the transmission electrode are capacitively coupled to each other, the first band controller performs control to provide a band that is necessary for a receiver to perform demodulation for the wideband communication, and when the transmission medium is not in contact with the transmission electrode, the first band controller performs control to provide a narrower band than the band that is necessary for the wideband communication.

摘要： In the conventional non-contact passive (power-source-less) IC card system method, a self-oscillator is built in a responder. The self-oscillator changes its oscillation frequency by the fluctuation of the power source voltage. Accordingly, it has been difficult to perform time management in the circuit in the responder. In order to solve this problem, in a carrier signal (micro wave) transmitted from an interrogator, the information to be transmitted is multiplexed by a clock frequency component reproduced by the responder. Upon reception of this, the responder extracts the clock frequency component from the modulated wave multiplexed and oscillates a stable frequency clock according to that component. Thus, it is possible to eliminate the problem that the information transfer rate of the circuit signal from the responder to the interrogator fluctuates according to the distance between the interrogator and the responder.
