摘要： An RFID tag section (10) is constructed from a seal material section (11), a substrate material section (12) formed in a layered manner on the seal material section (11), and a printing material section (13) formed in a layered manner on the substrate material section (12). On the surface of the substrate material section (12) is formed an RFID tag composed of an LSI chip (21), an antenna (22), and an impedance regulation section (23). Those portions of the seal material section (11) and the substrate material section (12) that are located below the impedance regulation section (23) are cut out, and an impedance regulation section cutout section (30) is provided in the cutout region. When the impedance regulation section cutout section (30) is cut out from the RFID tag section (10), the impedance regulation section (23) connected to the antenna (22) is separated from the RFID tag.

摘要： A portable display device, such as a contactless IC card, comprising, for example, cholesteric liquid crystal with a memory capability and having an improved mechanical durability. The display device has two opposed substrates (1) and display portion (liquid crystal) (2) interposed between the substrates (1). The display device further has a wall member (3) which is a wall structure holding the substrates at portions other than the display portion (2). The walls are perpendicular to the substrates (1), and the surfaces perpendicular to the walls are adhered to the substrates (1). The area of the surfaces adhered to the substrates (1) is larger than that of the surfaces of the display portion (2) opposing the substrates (1).

摘要： An IC card for transmitting information to an external device and/or receiving information from an external device, capable of displaying information effectively making the most use of the characteristics of cholesteric liquid crystal. The IC card comprises information display means for displaying predetermined information by transmitting/reflecting light by a method in which a stack of cholesteric liquid crystal layers (631, 632) reflecting red light while in the planar state and a cholesteric liquid crystal layer (633) reflecting blue light, and voltages are applied to the stacked cholesteric liquid crystal layers (631, 632, 633)respectively to change the aligned state of cholesteric liquid crystal molecules between the planar and focal conic states.

摘要： An IC card reading apparatus supporting different communication standards and providing users with excellent usability. Based on an instruction from a CPU, a linear power amplifier supplies, in a case of transmitting a radio signal of Type A, an antenna circuit with a power supply voltage of Type A supplied from a power supply switch circuit, and supplies, in a case of transmitting a radio signal of Type B, the antenna circuit with a power supply voltage of Type B supplied from the power supply switch circuit. In this way, both an IC card of Type A and an IC card of Type B can be read.

摘要： There is provided a small antenna for induction reader/writer capable of increasing the communication distance even when the antenna area or power supply to the antenna is restricted. The small antenna for induction reader/writer has a two-layer structure of loop antennas arranged at a predetermined interval and each comprising a printed board (2) for forming a loop pattern (1), the loop pattern (1) formed by etching the printed board (2), and a start terminal (3) and an end terminal (4) for supplying signal transmission power and outputting a received signal.
