    摘要： An acoustic impedance measuring apparatus emits ultrasonic waves to a target measurement object and measures the acoustic impedance of the target measurement object by ultrasonic waves fed back from the target measurement object. This acoustic impedance measuring apparatus includes an ultrasonic transducer, pulse signal generator, signal separator, frequency converter, parameter extractor, and acoustic impedance calculator. The pulse signal generator generates a pulse signal to be applied to the ultrasonic transducer. The signal separator separates, from an output from the ultrasonic transducer, an immediate ultrasonic response signal resulting from ultrasonic waves reflected by the surface of the target measurement object. The frequency converter obtains the frequency characteristics of the immediate ultrasonic response signal. The parameter extractor extracts predetermined parameters from the frequency characteristics. The acoustic impedance calculator calculates the acoustic impedance of the target measurement object by using the parameters extracted by the parameter extractor.

    摘要： A base station apparatus for a radiocommunication network in which radiocommunication with one or more radio terminal apparatuses is established according to a frequency hopping scheme. The base station apparatus includes a search section which searches for another radiocommunication network in the vicinity of the base station apparatus when the base station apparatus is started, and when another radiocommunication network is detected, obtains the pattern and time of frequency hopping in another radiocommunication network. A frequency hopping selection/setting section selects the pattern obtained by the search section as the frequency hopping pattern for the base station apparatus, and selects, on the basis of the time obtained by the search section, timing at which the frequency hopping based on the pattern does not cause frequency interference with respect to frequency hopping performed in another radiocommunication network, and carries out frequency hopping of the pattern at the thus-selected timing. It becomes possible to improve the throughput of the network system such as a radio LAN.

    摘要： Disclosed herein is an oral mobenzoxamine preparation which comprises a clathrate compound of mobenzoxamine or a salt thereof and cyclodextrin. Since the clathrate compound remains extremely stable even when stored for a long period of time and its absorption through the digestive tract is good upon its oral administration, the clathrate compound can be used advantageously as an orally-dosable preparation.
