摘要： For instance, a reflected electromagnetic wave received from a radio frequency identification IC tag through an antenna (105) is processed by capacitors (107, 110) and diodes (108, 109) without using a complicated circuit. A voltage of the reflected electromagnetic wave is integrated by combination of the capacitors (107, 110) and the diodes (108, 109). The reflected electromagnetic wave has different voltages due to a signal ''0'' and a signal ''1'' from the radio frequency identification IC tag. As a result, since an integration value outputted to a receiving signal line (113) also varies, the signal ''0'' and the signal ''1'' can be discriminated from each other by the radio frequency identification IC tag reader. Since integration is used, even weak signals can be discriminated from each other.

摘要： The appts. has memory units, a number of processors, a common bus, an address bus, a data bus, an answer bus connected between the memory unit and processors, and a bus control unit for controlling data transfer. The appts. includes separate bus request control lines associated with the address bus, data bus and answer bus and connected to the memory unit and processors. The bus control unit is connected to these control lines to control bus selection by a bus requesting unit and/or processor for each bus in response to a bus request signal.

摘要： Instructions are fetched from a cache memory by an instruction fetch unit. A decoder connected to the instruction fetch unit decodes an operand specifier and an operation code. On the basis of the decoded operand specifier, an address calculating unit calculates the address of the specified operand in the cache. An operand fetch unit then retrieves the operand from the cache address calculated. An operation code decoder is provided, in the decoder, to decode the operand from the cache address calculated.

摘要： A limiting condition such as transaction amount or the number of transactions is prestored in the protable terminal device. When an accumulated amount o transaction exceeds the limit, the transaction by the portable terminal device is inhibited and subsequent transactions are not permitted until the limiting item is reset. In this manner the accidental transaction amount is restricted and the stolen terminal device is made ineffective. Accordingly, the unauthorized and accidental transactions can be prevented.
