  • Authentication registration and cancellation device
    Patent number: 9064354
    Abstract: An authentication registration/invalidation apparatus is provided, which allows easy invalidation of an authentication tag when the authentication tag is lost, and facilitates management of authentication tags. When an RFID reader (2) receives an RFID signal including an instruction of invalidation, which is transmitted from an operation tag (10b) in a recognition area (A), an invalidation unit (32b) sets an operation mode to an invalidation enabled mode. If an RFID tag recognizer (31a) recognizes an authentication tag (10a) before or after the setting of the invalidation enabled mode, the invalidation unit 32b invalidates the authentication tag (10a), or invalidates all authentication tags (10a) that belong to a group to which the authentication tag belongs.

  • THERAPEUTIC AGENT FOR PERIODONTAL DISEASES AND METHOD OF TREATING PERIODONTAL DISEASES
    Publication number: 20110159462
    Abstract: A therapeutic agent is provided for periodontal diseases by which a biofilm formed inside hard tissues in an oral cavity is removed and the hard tissues are re-calcified. The biofilm formed in a fine fracture within contaminated tooth hard tissues is chemically dissolved and removed and calcium ions contained in the biofilm are precipitated as a calcium salt under an alkali condition so that the anatomically present fine fracture is sealed by the precipitated salt.
