摘要:
The present invention relates to a silent surface fastener, wherein the surface fastener is provided with noise suppressing means and auxiliary engaging and disengaging means, so that even if joining strength necessary for a surface fastener (1) cannot be obtained due to adoption of the noise suppressing means, not only the joining strength necessary for the surface fastener (1) is compensated by the auxiliary engaging and disengaging means, but also only a peeling noise suppressed by the noise suppressing means is generated at the time of peeling of the surface fastener because the auxiliary engaging and disengaging means generates no noise when the engagement of the surface fastener is released, and consequently, only a quiet sound of 80 dB at a maximum is generated.

A wireless IC tag mounted on a low magnetic permeability material is mounted on a holding part which has first and second surfaces and is made of a high magnetic permeability material. The holding part has a penetrating part which penetrates the first and second surfaces, and a notch which penetrates a part of the first and second surfaces at a periphery. A discontinuous region is formed on the holding part due to the notch, and at least on the penetrating part, the wireless IC tag is tightly held together with the low magnetic permeability material. An axis of reverse direction magnetic flux generated by an eddy current that flows in the periphery of the penetrating part and the notch is shifted from an axis of the magnetic flux produced by electromagnetic waves directed toward the wireless IC tag on the first and second surfaces.

A process for manufacturing the amorphous alloy member, and an authenticity determination device and an authenticity determination method using the amorphous alloy member.
摘要:
A short-range communication RFID which is a first identification medium 50 is incorporated in a top stop 5 of a slide fastener, and a hole 3c of a first pull tab 1 in a first pull-tab member 3a of a slider 2 has a second pull-tab member 3b removably attached thereto. The second pull-tab member 3b is provided with a long-range communication RFID which is a second identification medium 52. The second identification medium 52 is removably mounted an unillustrated article.Consequently, an identification medium for true-false decision on an article and a fastening product, and an identification medium for commodity distribution control on the article can be respectively mounted on the article. Furthermore, secrecy in the identification medium for commodity distribution control can be secured by removing the identification medium for commodity distribution control from the article. Further, the removed identification medium for commodity distribution control can be reused by mounting it on another new article.
