摘要： An antenna apparatus for detecting an optimum directivity. The apparatus has an antenna capable of having plural directivities at predetermined directions; a scanning signal generator coupled to the antenna for generating a scanning signal for scanning the plural directivities from the first directivity to the last directivity; a signal level memory coupled to the antenna for memorizing plural memorized signals which are proportional to the output signal levels of the antenna at the plural directivities, respectively, when the plural directivities are scanned by the scanning signal; a detector coupled to the signal level memory memorized for detecting a maximum level memory signal from among the plural memorized signals after the scanning; and a controller coupled between the scanning signal generator and the detector for controlling the scanning signal generator in response to the maximum level memorized signal so as to fix the directivity of the antenna at the directivity corresponding to the maximum level memorized signal.

摘要： Problem of the present invention is to enable elimination or reduction of a signal wire in a dedicated cable for a magnetic bearing device for supplied an electric power from a control device to a magnetic bearing main unit via the dedicated cable. A magnetic bearing device 100 according to the present invention has a magnetic bearing main unit 10 having an electromagnet 12M for magnetically levitating and rotatably supporting a magnetic rotating body 11 and functioning as a magnetic bearing, a control device 20 having a compensating circuit 25 for generating a control signal for controlling a levitation position of the magnetic rotating body 11, and an electricity supply line 30L for supplying an electric power from the control device 20 to the magnetic bearing main unit 10. The magnetic bearing main unit 10 has a modulation carrier circuit 22 for generating a modulated wave and a first alternating-current coupling section 23A for transmitting the generated modulated wave to the control device 20 by the alternating-current coupling with the electricity supply line 30L. The control device 20 has a second alternating-current coupling section 23B for separating the modulated wave alternating-current coupled from the electricity supply line 30L and a carrier wave demodulating circuit 24 for detecting the separated carrier signal wave.
