Patent
Transmitter-receiver for non-contact IC card system
TL;DR: In this paper, a non-contact IC card system which transmits and receives signals between an interrogator and a transponder, a transmitter-receiver used for the interrogator comprises a distance detecting means for detecting the distance between the interrogators and the transpiders, and an output control means for controlling the output level of the operator in accordance with the signals detected by the distance detector.
Patent
Non-contact IC card and process for its production
TL;DR: In this article, a non-contact IC card comprising a substrate and provided thereon at least an IC chip and an antenna coil formed by etching, a connecting terminal of the antenna coil and a connecting bump of the IC chip are interconnected in a face-down fashion via an anisotropic conductive adhesive layer, or interconnected by wire bonding.
Patent
Antenna for reader/writer
TL;DR: In this article, an antenna for reader/writer of an interrogator in a non-contact data carrier system comprising the interrogator and a transponder was proposed. But the authors did not consider the effect of magnetic coupling between the receiving antenna and the transmitting antenna.
Patent
Antenna device and communication device
TL;DR: In this article, an antenna device, capable of stable communications without increasing a space of the entire device by keeping a resonance frequency substantially constant even if the temperature changes, is described.
Patent
Optical disc case, optical disc tray, card member, and manufacturing method
TL;DR: In this article, the authors present an optical disc case, in which a face cover portion and a rear-face cover portion are connected so as to be rotated with the end portion side of each of the principal faces thereof as the center, and the case including a protruding holding portion, configured to fit into a central hole formed in the optical disc.
