摘要： A soft magnetic member (5) which is formed by a composite of an organic object such as a metal grain powder, a flake, a ferrite grain powder, a ferrite, an amorphous film or a layered member of the amorphous film with 10 mm or lower thickness so as to satisfy a predetermined relationship with an antenna area, a circumference length, and a magnetic transmission ratio and a conductive member (7) which has approximately 10×10−8 Ωm or lower, more preferably 0.005 Ω or lower initial resistance are provided between the an antenna coil which is formed at least one loop and a metal surface (6) of the conductive member such as a metal casing. The magnetic flux which invades into the conductive object is blocked by the soft magnetic member (5) and the conductive member (7) so as to restrict the influence thereof. By doing this, it is possible to provide a reader/writer antenna for an RFID system in which it is possible to restrict a variance of a resonating frequency and an increase in a loss even if it is disposed so as to contact the conductive object such as a metal casing.

摘要： A curtain coating width changing device in which the width of the backup device at a coating portion can be rapidly changed continuously and smoothly. A backup roller supports a continuously running web. A pair of collar members is provided at respective opposite edge portions of the backup roller and is movable in the axial direction of the backup roller, the collar members lying on an extension of a top portion of the backup roller. A pair of spacers is provided in the spaces between the roller and corresponding ones of the collar members so as to form an extended surface of the top portion of the backup roller and to fill the spaces. Each of the collar members has a spiral end surface, whereby the effective axial length of the extended portion of the top portion of the roller can be adjusted by rotation of the spacers.

摘要： An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.

摘要： A body detecting element is buried in the ground together with a body such as a metal body and includes a magnetic member acting as a magnetic core, an antenna coil wound around the magnetic member and a capacitor connected to both the ends of the antenna coil for forming a resonance circuit together with the antenna coil. The antenna coil is mounted on the body integrally therewith through an electromagnetic shield member with the outer peripheral surface thereof confronting the outer surface of the body. A body detecting element includes an RFID circuit connected to the antenna coil and mounted on a body integrally therewith such that the outer peripheral surface of the antenna coil confronts the outer surface of the body through an electromagnetic shield member. Even if the body detecting element is mounted on the body such as the metal pipe integrally therewith, it can accurately detect the body because a resonant frequency and the Q value of the coil are not changed. There is almost no possibility that detecting element is broken or moved even if a body other than the above body is dug.
