A method of manufacturing a head suspension includes a punching process, a positioning process, and an affixing process. An objective part on the head suspension to which a damperis affixed includes a discontinuous section. The punching process punches a damper material into the damperwhose shape corresponds to the shape of the objective part excluding the discontinuous section. The positioning process positions the damperto the objective part so that the damperavoids and surrounds the discontinuous section, and the affixing process affixes the damperto the objective part. The method secures a uniform damping effect among manufactured head suspensions and improves the yield of dampers and head suspensions without deteriorating the functions and performances of the head suspensions.

A communication apparatus includes a first RF tag which performs communication using electromagnetic waves in a first frequency band; a second RF tag which performs communication using electromagnetic waves in a second frequency band different from those in the first frequency band; a storage unit having a shared area accessible from the respective RF tags; and a power controller which generates power for driving the first RF tag and the storage unit using the first frequency band electromagnetic waves and supplies the generated power to the first RF tag and the storage unit, and which generates power for driving the second RF tag and the storage unit using the second frequency band electromagnetic waves and supplies the generated power to the second RF tag and the storage unit.

Method of manufacturing a head suspension

Laser beam irradiation areas are provided in a load curve portion and an angle adjustment portion of a suspension. The laser beam irradiation areas are oriented in a direction in which the suspension is to be bent. A laser beam having a predetermined length and a predetermined shape is irradiated onto each laser beam irradiation area.

Thin plate formation method, thin plate and suspension correction apparatus, and correction method

An RFID tag unit is constituted of a seal member part, a substrate material part layered on the seal member part, and a print member part layered on the substrate material part. An RFID tag that comprises an LSI chip, an antenna and an impedance adjustment part is formed on the surface of the substrate material part. Of the seal member part and substrate material part, a part positioned under the impedance adjustment part is cut off, and an impedance adjustment part cutoff part is equipped in the cutoff area. Cutting the impedance adjustment part cutoff part off the RFID tag unit cuts the impedance adjustment part, which has been connected to the antenna, from the RFID tag.

Metal-suitable RFID tag and RFID tag unit therefor

An RFID tag includes an RFID unit and an antenna unit. The RFID unit is formed in a form of a minute dipole antenna having a predetermined length and includes an IC chip. The antenna unit includes an antenna pattern and an RFID mounting portion. Lengths of the RFID unit and the antenna unit are substantially identical. The RFID unit and the antenna can be manufactured independently.

A tag testing device uses an infrared camera to take an image of a plurality of radio frequency identification tags, compares the image with a stored standard tag pattern image storage, and detects defective tags based on the comparison. A radio wave transceiver bulk reads the tags using anti-collision, a tag response counter counts a number of tag responses, and a defective tag detector compares a number of heat emitting tags based upon the image processing with a number of tag responses counted by the tag response counter. If the number of heat emitting tags does not match a number of responsive tags, a number of the tags tested are changed by partially shielding the tags and the radio wave transceiver repeatedly bulk reads the tags using the anti-collision function while a shielding range is gradually changed, thereby narrowing down other possible defective but heat emitting tags.

A passenger management system having a boarding processing system with a plurality of tag readers and speakers connected to an automatic broadcasting unit each located in a plurality of areas into which a premises of an airport is divided. If there is found a remarked boarding card with which the check-in has been completed at a checking counter but boarding has not been confirmed, the tag readers are successively actuated from a gate counter and an area among said plurality of areas in which said remarked boarding card is present is determined based on the signal received by said tag readers. In such a way, remarked boarding cards, namely not-boarded passengers are managed for each area.
