  • Patent number: 9251456
    Abstract: An RFID information medium transmits and receives data to and from an external reader in a noncontact manner. The RFID information medium is provided with a main body section having an insulating member, either an antenna or an antenna member arranged on the main body section, and a conductor arranged on the main body section. The conductor has a conductive material layer. The conductive material layer partially overlaps the antenna or the antenna member in the thickness direction of the main body section.

  • Patent number: 8376236
    Abstract: A contactless integrated circuit (IC) label has an IC chip and is capable of exchanging data with an external reading device without contact. The contactless IC label includes: a transparent label base material; an optical variable device formed on a lower surface of the label base material; a conductive layer bonded to and formed on a lower surface of the optical variable device, and configured to function as an antenna of the IC chip; a connecting layer electrically connected to the IC chip; an insulating layer formed between the conductive layer and the connecting layer, and configured to electrically couple the conductive layer and the connecting layer; and an impedance adjusting unit formed on at least the connecting layer of the conductive layer and the connecting layer, and configured to adjust impedances of the conductive layer and the IC chip.

  • Patent number: 6378774
    Abstract: A smart card comprises an IC module and an antenna for non-contact transmission. The IC module has both a contact-type function and a non-contact-type function. In the contact-type function, power reception and signal transmission/reception is effected via an electrical contact. In the non-contact-type function, power reception and signal transmission/reception is effected in a non-contact state by an electromagnetic coupling system without providing the IC card with an electrical contact. The IC module and the antenna comprise first and second coupler coils, respectively, which are disposed to be closely coupled to each other, and the IC module and the antenna are coupled in a non-contact state by transformer coupling. An antenna coil is disposed so as not to overlap an engagement portion for the IC module, which is a region of an external terminal electrode serving as a contact-type electrode, an embossing region, or a magnetic stripe region.

  • Patent number: 5114207
    Abstract: In a vehicle body construction for an industrial vehicle of the kind which is powered by a storage battery, a pair of deck plates are secured to open upper ends of a pair of parallel side frames, the deck pates being in the form of planar single plates which are disposed horizontally. A pair of braces and a steering axle mounting member are secured to the lower surfaces of extensions of the deck plates so as to serve as reinforcements therefor. A pair of front battery unit support plates are respectively disposed on the deck plates and are secured to the rear ends of a pair of drive axle mounting plates which are secured to the front portions of the side members and the deck plates. A rear battery unit support plate extends between the extensions of the deck plates so as to be placed thereon and secured to the same.
