  • Patent number: 7478473
    Abstract: The productivity of an IC card is to be improved. In a memory card of the type in which a memory body having a wiring substrate and a semiconductor chip mounted on a main surface of the wiring substrate is held so as to be sandwiched in between a first case and a second case, a planar outline of the memory body is smaller than half of a planar outline of the memory card. The memory body is disposed so as to be positioned closer to a first end side as one short side of the memory card with respect to a midline between the first end side and a second end side as an opposite short side of the memory card positioned on the side opposite to the first end side. The other area than the memory body-disposed area in the first and the second case is used as another functional area.

  • Publication number: 20080283619
    Abstract: An IC card is prevented from falling off readily an electronic device while maintaining the mechanical strength of the IC card. A recess for preventing a memory card from falling off an electronic device is provided at the side of one side of a principal surface of a cap of the memory card which is configured by fitting a memory body in a recess formed on a parts mounting surface of the cap. The bottom of the recess is terminated in the middle of the thickness of the cap. This construction makes it possible to prevent the memory card from falling off readily an electronic device while maintaining the mechanical strength of the memory card.

  • Publication number: 20080272197
    Abstract: An antenna connection function for a noncontact interface is provided by suppressing a modification in a pin arrangement and a pin shape of a memory card that does not correspond to the noncontact interface. Two antenna connecting pins having the memory card are divided into two areas in which a size of one potential supply pin is the largest and used as a split pin arranged at intervals. Because a size of the two antenna connecting pins is at maximum as large as the size of the potential supply pin, the two antenna connecting pins are provided and the memory card that corresponds to the noncontact interface is obtained by devoting a pin area having the size of the one potential supply pin to the memory card that does not correspond to the noncontact interface. Accordingly, the pin area of the memory card that corresponds to the noncontact interface can be formed without departing from the pin area of the memory card that does not correspond to the noncontact interface.

  • Publication number: 20080073436
    Abstract: The present invention provides a memory card equipped with an interface controller connected to external connecting terminals, a memory connected to the interface controller, and a security controller connected to the interface controller. A second external connecting terminal capable of supplying an operating power supply to the security controller is provided aside from a first external connecting terminal which supplies an operating power supply to the interface controller and the memory. An interface unit of the interface controller connected to the security controller receives the operating power supply from the second external connecting terminal and thereby enables a stop of the supply of the operating power supply from the first external connecting terminal. Even if the supply of the operating power supply to the interface controller is cut off, the output of the interface unit is not brought to an indefinite state.

  • Publication number: 20080042563
    Abstract: When light is incident to an antenna layer AA6 of a photocathode AA1, light of a specific wavelength included in the incident light couples with surface plasmons in the antenna layer AA6 whereupon near-field light is outputted from a through hole AA14. The intensity of the output near-field light is proportional to and greater than the intensity of the light of the specific wavelength. The output near-field light has a wavelength that can be absorbed in a photoelectric conversion layer AA4. The photoelectric conversion layer AA4 receives the near-field light outputted from the through hole AA14. A region of the photoelectric conversion layer AA4 around the through hole AA14 absorbs the near-field light and generates photoelectrons (e?) in an amount according to the intensity of the near-field light. The photoelectrons (e?) generated in the photoelectric conversion layer AA4 are outputted to the outside.

  • Publication number: 20070262239
    Abstract: When light is made incident into antenna layers 11a, 11b, and 11c of a photodetector 1, specific wavelength components of light contained in the incident light combine with surface plasmons of the antenna layers 11a, 11b, and 11c, and surface plasmon resonance occurs. Thereby, near-field lights are outputted from through-holes 13 of the antenna layers 11a, 11b, and 11c. The near-field light outputted from each through-hole 13 reaches a light absorbing layer 4 via light receiving surfaces 4a, 4b, and 4c. The light absorbing layer 4 generates a charge of an amount according to the amount of received light. Since cycle intervals ?a, ?b, and ?c of convex portions 12 in the antenna layers 11a, 11b, and 11c are different from each other, the wavelength component of light that combines with a surface plasmon differs in each of the antenna layers 11a, 11b, and 11c. Consequently, a plurality of wavelength components of light can be detected.

  • Publication number: 20070150633
    Abstract: An IC card and card adapters are designed so that the IC card of a specific standard (e.g., MMC standard) is compatible with IC cards and terminals of other standards (e.g., MS card standard and USB terminal standard). In the IC card (MMC), a controller IC, which is connected to a flash memory, includes a voltage pull-down detector, a mode controller, a USB-mode interface controller, a MS-mode interface controller, and an MMC/SD-mode interface controller. The card adapters suffice to have component parts which are easy in formation and low in cost such as wiring lines and resistors. The voltage pull-down detector of the IC card detects the voltage pull-down caused by the resistors, and the mode controller selects the USB-mode interface controller, MS-mode interface controller or MMC/SD-mode interface controller so that the IC card becomes compatible with the corresponding IC card standard.
