摘要： A shaped-wave application section inputs a first pulse signal corresponding to transmission data output from a transmission data output section, and applies, to a modulation and amplification section, a signal wave corresponding to a second pulse signal such that the waveform of the first pulse signal is shaped. The pulse signal applied to the base of the transistor of the modulation and amplification section is amplitude-modulated into an amplitude-modulated wave in which the amplitude-modulated portion is strengthened, in accordance with the signal wave corresponding to the second pulse signal applied to the emitter thereof. The amplitude-modulated wave is supplied to an antenna section including a resonance circuit via the collector thereof, and is transmitted as an electromagnetic wave from the antenna section.

摘要： An antenna unit prevents a communication error by suppressing side lobes formed by an antenna coil segment of a reader/writer device. The antenna unit (200) is used for a reader/writer device (20) whose signal processing circuits (210) and (220) communicate with an IC card (10) via electromagnetic waves, wherein an antenna coil (100) of the IC card (10) relatively gets close to the antenna unit (200). The antenna unit (200) includes the antenna coil segment which forms a loop antenna (202) on a substrate (201) and conductor segments (203) at the periphery of the antenna coil on substantially the same plane of the antenna coil.

摘要： A memory region on an IC card has a hierarchical structure. Each application allocated on the memory region is registered in a directory, and the memory region is managed in directory units. A personal identification code is set for each application and directory, and the access right is controlled in application units or directory units. If a mobile terminal is lost, the right to access each application in the IC card automatically disappears. Therefore, the right to access each application allocated to the memory region on the IC card is efficiently controlled.

摘要： A semiconductor integrated-circuit device rectifies a received carrier wave, generates a first power-supply voltage based on the rectified output, and selects, as a power-supply voltage required for operation, one of the first power-supply voltage and a supplied second power-supply voltage. The first power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is lower than a threshold value. The second power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is equal to or higher than the threshold value and an instruction to operate in accordance with a predetermined function is given.
