摘要:
On the basis of a finding that a magnetic hysteresis of a metal material, among magnetization characteristics changing with secular degradation of the metal material, shows a clear correspondence with the degree of degradation of the metal material, a change in such a magnetization characteristic is measured to estimate the degree of secular degradation of the metal material, In a typical embodiment, a superconducting quantum interference device is used to detect the magnetization characteristic of a measuring object. According to the present invention, the degree of embrittlement of a metal material used in an environment of high temperatures can be quickly detected in a non-destructive fashion so that the danger of brittle fracture of the metal material can be reliably prevented.

The vehicle roof mount antenna to be detachably mounted on a vehicle roof is mainly constituted by an antenna cover 1, an antenna base 2, a boss 3, a pad 4, an annular rib 5, and an annular groove portion 6. The pad 4 has a boss hole 7 through which the boss 3 penetrates and is disposed between the antenna base 2 and the vehicle roof R. The annular rib 5, which is made of an elastic material, is provided on the vehicle roof R side surface of the pad 4. When the vehicle roof mount antenna is fixed to the vehicle roof R, the annular rib 5 is inclined from the boss hole 7 toward a periphery of the pad 4. The annular groove portion 6 is provided at a position where the pressing force of the annular rib 5 against the vehicle roof R can be reduced.

There is provided person oneself authenticating means for authentication of a user, which is mainly used for person oneself authentication in Internet banking or the like and is high in security, and is realizable by functions ordinarily provided in a PC, a mobile phone, or the like, the authenticating means being less in burden required for user authentication key management and authentication operations. Sound or an image is adopted as an authentication key for person oneself authentication. Authentication data is edited by combining an authentication key, which is selected by a registered user, and sound or an image that is other than the authentication key, and the authentication data is continuously reproduced in a user terminal. A time in which a user has discriminated the authentication key from the reproduced audio or video is compared with a time in which the authentication key should normally be discriminated, which is specified from the authentication data. When both times agree, the user is authenticated as a registered user.

A fluxmeter includes an application unit for applying a magnetic field, a superconducting quantum interference element and a flux transmitting circuit. The flux transmitting circuit includes a pickup coil formed of a superconducting print coil and a core for the pickup coil. The core is formed of a soft magnetic material. The core serves to suppress the leakage of magnetic flux to magnetically couple the pickup coil and the superconducting quantum interference element efficiently to improve the sensitivity and resolution of the fluxmeter. The pickup coil may be manufactured by photolithography, sputtering, laser beam deposition, MBE deposition, MOCVD or spray pyrolysis.
