摘要:
A non-contact IC recording medium that operates in response to a radio instruction from a reader/writer includes a write-protect area setting unit that sets a write-protect area where a writing of data is prohibited; an area determining unit that determines, when data for the writing is received, whether an area where the data is to be written is the write-protect area; and a write processing unit that writes, when the area determining unit determines that the area is not the write-protect area, writes the data in the area, and changes the area into the write-protect area.

An RFID tag includes: a tag main body having a communication antenna, a circuit chip electrically connected to the antenna to perform wireless communication via the antenna, and a tabular sealing member in which the antenna and the circuit chip are enclosed; a print layer formed on a first surface of the tag main body by printing; and a protective film that covers the print layer. The print layer is formed only in a central area of the first surface surrounded by a marginal area of the first surface extending along the outer edge of the first surface. The protective film includes a covering portion that covers the print layer and an adhering portion that lies off the print layer while surrounding the outer edge of the print layer and adheres to the first surface.

A radio-frequency identification (RFID) tag includes: a plate-shaped sealing piece made of an elastic material. An inlet is enclosed within the sealing piece. The inlet includes an electronic component and an antenna connected to the electronic component. A pair of reinforcing pieces are located respectively on the front and back surfaces of the sealing piece so as to sandwich the electronic component. The reinforcing pieces are made of a first material harder than the elastic material. A joint piece configured to couple the reinforcing pieces to each other. The joint piece is made of a second material harder than the elastic material.

In order to provide a compact loop antenna, for use in an inductive read/write apparatus, capable of extending a communication range even if the antenna area or power supply thereto is constrained, a compact loop antenna, for use in an inductive read/write apparatus, comprises two layers of loop antennas, each thereof comprising a printed circuit board 2 for featuring a loop pattern 1, a loop pattern 1 formed by an etching process on the printed circuit board 2, and a start terminal 3 and a end terminal 4 for supplying power for signal transmission and outputting a received signal and each thereof maintaining a predetermined distance from each other.
摘要:
An interrupt control system in which a main process device executes an interrupt process, having a high process priority. The process priority is registered in a table, corresponding to each interrupt generating source, and an intermediate process device receives an interrupt signal from each interrupt generating source, obtains the corresponding process priority from the table and informs the main process device of the interruption. Accordingly, the process priority can be easily changed, and the system has a small size because the interrupt circuit for the main process device is centralized.

An RFID tag includes an inlay which has a base, an antenna formed on the base, and an IC chip. The IC chip is enclosed in a surface mount package and soldered to the antenna and carries out radio communication through the antenna. The RFID tag further includes underfill that fills a gap between the base and the surface mount package, and a sheath protecting material enclosing the entire inlay.
