Disclosed is a spread-spectrum communication system that can increase an information transmission rate under conditions of a prescribed bandwidth and expansion ratio, and that can obtain chip timing and symbol timing synchronization characteristics comparable to those of a conventional spread-spectrum system. Using a delay element and a selector, a spreading code sequence for a Q-phase signal for quadrature modulation is phase-modulated with second information, whereas no phase modulation is applied to a spreading code sequence for an I-phase signal. At the receiving end, chip timing synchronization and code synchronization are performed for the I-phase signal.

A generator section and a pair of drive sections are disposed along the lengthwise of a piezoelectric ceramic plate. The one pair of drive sections are disposed at both ends or at one end of the plate and have a pair of electrodes for each. The piezoelectric ceramic plate in the drive sections are polarized oppositely in direction and connected to a pair of external terminals. The generator section has two pairs of opposed electrodes which are polarized oppositely from the center along the lengthwise of the plate. The two pairs of opposed electrodes are respectively short-circuited and connected to external terminals. A voltage can be taken out from between the external terminals of the generator section at the vibration nodes when the piezoelectric ceramic plate in the drive section is vibrated by applying an AC voltage to between the input terminals on the drive section side at the resonance frequency of the fourth-order mode longitudinal vibration in lengthwise. This 4-terminal piezoelectric ceramic transformer has a high-voltage/high-reliability and is easy to handle in the design of a peripheral circuit.

A non-contact type IC card includes a power-supply receiving device for receiving power through electromagnetic coupling with a terminal unit; a signal transmitting/receiving device for exchanging signals with a terminal unit; a signal processing device, connected to the power-supply receiving device and the signal transmitting/receiving device, for processing signals; and a resetting device, connected to the signal processing device, for resetting the signal processing device when there is no signal exchange. A method of initializing a non-contact type IC card which receives power through electromagnetic coupling with a terminal unit and which exchanges signals with the terminal unit includes measuring elapsed time from a signal exchange between an IC card and the terminal unit and resetting the IC card if no signal exchange occurs after the elapsed time exceeds a predetermined value.
