Abstract:
An object of the present invention is to provide a total reflection measuring apparatus which, while visually observing a specific minute area of a measurement object, is capable of efficiently obtaining optical data on the basis of the total reflection measurement. A microscopic total reflection measuring apparatus of the present invention comprises a Cassegrain mirror 12 having a Cassegrain primary mirror 16 and a Cassegrain secondary mirror 18, which condenses an incident light beam 30 on a measurement object 20 by making an incident light beam successively reflected by the secondary mirror 18 and the primary mirror 16, and which obtains a reflected light beam 32 from the measurement object 20 by making the reflected light beam 32 successively reflected by the primary mirror 16 and the secondary mirror 18. And, a total reflection prism 14 is arranged below the Cassegrain secondary mirror 18. And the incident light beam includes a visible light beam for visual observation and a measurement light beam for acquisition of analysis information, and present invention comprises a visible light filter which separates at least one of the incident light beam to the total reflection prism and the reflected light beam from the total reflection prism 14 into a total reflection area B and a normal reflection area A, and which removes, from the one of the incident light beam and the reflected light beam, the visible light beam in the total reflection area B.
Abstract:
In a service provider system, a service provider provides service information dependent on location information of a mobile terminal to the mobile terminal in response to a service request with the location information sent by the mobile terminal. A communication control unit controls communication between the mobile terminal and the service provider. The communication control unit converts a user identifier of the mobile terminal in the service request to a temporary identifier for the communication.

Abstract:
A bias current to be supplied to an amplification circuit 60 is drawn out of a collector of a transistor Q11 of a bias circuit 10. The drawn-out bias current is input to a base of a transistor Q13 via an attenuation filter F2 and is output from an emitter of the transistor Q13 in the state where the voltage thereof is reduced by a level corresponding to Vbe. The attenuation filter F2 is conducted in a DC manner, and attenuates a component of a frequency fH(=2ft−fr) defined by a transmission frequency ft and a receiving frequency fr of a radio frequency signal. The bias current output from the emitter of the transistor Q13 is supplied to the amplification circuit 60 via an attenuation filter attenuates a component of a frequency fL(=|fr−ft|).
