Abstract: An object is to prevent eavesdropping in quantum key distribution. A photon detector outputs an output current indicating a result of detecting a quantum signal. A current-voltage conversion unit converts the output current into an output voltage signal. An analog-to-digital converter outputs an output voltage signal obtained by analog-digital conversion of the output voltage signal. A signal processing unit performs predetermined signal processing on the output voltage signal, and outputs a photon detection signal indicating a result of detecting the quantum signal. When a time difference between a timing at which the quantum signal is incident into the photon detector and a reference timing determined based on a clock signal is not within a determination range, the photon detection signal is not output from the signal processing unit.

Abstract: A slider 37 having a rod-pressing portion 35 for pressing a rod 23 into a rod-engaging recess 25 is movably provided on a holder body 27 having the rod-engaging recess 25. The holder body 27 includes a pressing state holding mechanism for relatively moving the slider 37 with respect to the holder body 27 to hold the rod 23 in a state in which the rod 23 is pressed against the rod-engaging recess 25 by the rod-pressing portion 35. The pressing state holding mechanism includes a screw rod movably, detachably and threadedly engaged with a screw hole formed in the holder body 27. A tip end of the screw rod 45 and the slider 37 connected to each other such that they permit rotation of the screw rod 45 with respect to the slider 37 but move integrally with respect to the holder body 27, and the slider 37 can be attached to and detached from the slider 37.

Abstract: The present invention is directed toward realizing the distribution of advertisements that can attract the attention of users to advertisements and thus maximize the effect of the advertisements. A matching table stores correspondence information for linking advertisement information to events that are to be reported to user terminals. The event recognition unit of a server terminal recognizes the occurrence of an event that is to be reported to a user terminal, and a matching unit refers to the matching table and specifies the advertisement information that has been linked to the event that has been recognized. A distribution control unit, instead of performing a process of reporting the recognized event to the user terminal by way of the communication network, fetches the specified advertisement information from an advertisement storage unit and transmits the specified advertisement information to the user terminal by way of the communication network.

Abstract: An apparatus for demodulating a data signal read from a recording medium, in which data is recorded on at least a portion of the recording medium. The data is recorded using a recording system having a substantially constant linear velocity. In this manner, the recording medium is rotated at a substantially constant speed during the reading of data signals such that one of a frequency and an amplitude of the read data signal varies. The apparatus includes a signal processor for processing the read data signal in response to a change in one of the frequency and amplitude to produce a processed data signal suitable for demodulation. Once the processed data signal is produced, a demodulator operates to demodulate the data signal and to produce a demodulated data signal.
