摘要： An interrogator that is to be incorporated in a communication system in which each of at least one transponder is operable, upon reception of a main carrier wave transmitted from the interrogator, to respond to the interrogator with a reflected wave that is generated by modulating the main carrier wave. The interrogator includes: (a) a transmitting portion operable to transmit the main carrier wave; (b) a receiving portion operable to receive the reflected wave as a received signal; (c) at least one first frequency-converter each operable to generate an intermediate frequency signal, by multiplying the received signal with a first local signal that is generated by a first local oscillator; (d) at least one second frequency-converter each operable to generate a demodulated signal, by multiplying the intermediate frequency signal or a converted signal converted from the intermediate frequency signal, with a second local signal that is generated by a second local oscillator; and (d) a phase controller operable to control phase of the second local signal.

摘要： An image reading device includes a sheet setting portion, a reading unit, a detecting unit, and a controller. The conveying unit is configured to convey a sheet in a conveying direction at a first velocity. The reading unit is configured to read the sheet at a reading position. The detecting unit is configured to detect the sheet at a detection position upstream of the reading position in the conveying direction. The controller is configured to control the conveying unit to initiate conveyance of sheet, and configured to control the reading unit to start reading the sheet when the sheet is detected. The controller controls the conveying unit to convey the sheet at a second velocity slower than the first velocity when the sheet is not detected after a prescribed period of time has elapsed since the conveying unit initiates the conveyance of sheet.

摘要： When currents are applied to driving coils, electromagnetic forces are generated between the currents and magnetic fluxes passing through gaps, a shaft member is swung in one direction, and a tilt angle of a mirror (controlled object) changes relative to a support center point. Electromotive forces generated in detection coils when the magnetic fluxes pass through the detection coils are given as feedback signals to a control unit. The control unit generates currents on the basis of the feedback signals, and applies the currents to the driving coils. By detecting the velocity of the mirror during swinging with the detection coils, the structure of the actuator can be simplified. Further, the responsivity can be increased, and the tilt angle of the mirror can be detected with high accuracy.
