TL;DR: In this paper, a sealing part 17 covers an antenna substrate and a magnetic core member 12 while the flat plate-shaped magnetic core members 12 is laminated in parallel with the antenna substrate 11 with an air core coil formed therein.

Abstract: PROBLEM TO BE SOLVED: To eliminate influences upon communication by the limitation of an installation part of an information reader/writer. SOLUTION: The repeater comprises a first antenna coil 31 electromagnetically coupled with an antenna coil 11 that an information reader/writer 10 has, a second antenna coil 32 serially connected with the first antenna coil 31 and electromagnetically coupled with an antenna coil 21 that a non-contact information medium 20 has, and a tuning capacitor 33 serially connected with the first antenna coil 31 and the second antenna coil 32. The first antenna coil 31, the second antenna coil 32 and the tuning capacitor 33 are realized by forming a resonance circuit 34 which resonates in the same resonant frequency as the frequency of a resonance circuit 13 that the information reader/writer 10 has and as the frequency of a resonance circuit 23 that the non-contact information medium 20 has.

TL;DR: In this article, the authors propose a system and a method of radio communication constituted so that communication setting data required for the radio communication from a connecting device to a connected device are preliminarily acquired by the connecting device in the case of starting connection by the radio communications.

TL;DR: In this article, the authors propose a solution to enable fast access by making a connection with electronic devices which have mutually different kinds of interfaces without requiring any adapter for conversion. But the solution is limited to the case where the interface controller A21 and B24 have different internal interface control part for writing and reading data to and/or out of the storage.

TL;DR: In this article, an optical sensor was attached to the spectacle lens made of a liquid crystal panel, detecting the quantity of light transmitted through a spectacle lens, and making ratio between the detected light quantity and the luminance of the back light constant.
