A first object of the present invention resides in providing a novel installation structure for an RFID tag, which effectively protects the RFID tag from external stress or impact during the storage, transportation and usage, and allows communication with the external. A second object of the present invention resides in that providing a novel installation structure for an RFID tag, which enables communication with the external even if the RFID tag is installed on a conductive member such as a metal member, and the surface thereof is covered with a protective member typically made of a metal which has an excellent strength and durability. A third object of the present invention is to provide a communication method using an RFID tag as being surrounded by a conductive member typically made of a metal. Even if an RFID tagis housed in a container A typically made of a conductive material such as a metal having a large mechanical strength, the RFID tagcan communicate with an external read/write terminalas mediated by leakage magnetic flux if only a flux leakage pathcomposed for example of a gap is formed in such container A.

Housing structure for RFID tag, installation structure for RFID tag, and communication using such RFID tag

This invention aims to provide a communication device, installation structure for the communication device, a method of manufacturing the communication device, and a method of communication with the communication device in which the communication device is able to exceedingly restain a conductive material from attenuating magnetic flux and to expand communication distance even when the communication device is attached to a conductive member e.g., metal, in a closely contacting manner. This invention has a sheet-like amorphous magnetic material being arranged in a manner extending from a magnetic flux generating portion of a concentric disk-shaped antenna coil of an RFID tag serving as the communication device to an outer area of the antenna coil.

Apparatus and method for a communication device

An RFID tag installing structure for installing a microminiaturized RFID tag having a cylindrical antenna coil to a conductive member, an RFID installing method, and communication method are disclosed. An RFID tag () having a cylindrical antenna coil () and shaped into a rod is characterized in that the axial direction of the RFID tag () is parallel to the installation surface composed of the bottom surface () of an installation groove () made in a conductive member () and is in contact with the installation surface.

The present invention is provided with a key hole insertion fitted to a manhole cover, a manhole cover locking apparatus equipped with the key hole insertion, a manhole cover locking system, a method for unlocking the manhole cover, and a control system for opening and a closing manhole cover, which is designed to prevent an external access to the key hole of the manhole cover, thus attaining a sound and severe locking management. The electrical locking assembly can be added to conventional manhole covers in a simple way. The structure of the invention is characterized in a key hole insertion A inserted in a key hole of the inner manhole cover or the key hole of the manhole cover enough to engage pins with engaging openings of the cap holding member secured to the key hole or the key hole This allows the key hole insertion A to be locked to the key hole or the key hole It is also characterized in that the control chip mounted in the inserting portion after receiving the unlock signal sent from external R/W terminal transmits a control signal to pull the pins inward enough to be released from the engaging opening and thus the access to the key hole or is available.
