摘要： An amplifier circuit performs an amplification of a carrier signal received by a transmitting and receiving unit. The amplifier circuit includes an impedance matching circuit that performs matching of an impedance of the amplifier circuit when the transmitting and receiving unit and the amplifier circuit are connected. A superposition wave generating unit generates a superposition wave which is superimposed on the received carrier signal. A driver outputs an amplified carrier signal which is obtained by adding the superposition wave to the received carrier signal. An amplitude detecting unit detects whether the received carrier signal is a predetermined carrier signal superimposed with a predetermined communication signal, based on changes of an amplitude value of the received carrier signal. When the predetermined carrier signal is detected, the amplifier circuit outputs the amplified carrier signal.

摘要： An IC tag read-write apparatus includes a control circuit, a transmission link, and a plurality of antenna units. The control circuit controls data relative to an outgoing carrier wave and an incoming carrier wave. The antenna units correspond to a plurality of IC tags. Each of the antenna units includes a modem, a first antenna, and an indication circuit. The modem is connected to the control circuit through the transmission link and modulates the carrier wave based on the data in a data writing operation and demodulates the incoming carrier wave in a data reading operation. The first antenna sends the modulated carrier wave by air to a second antenna of a corresponding one of the IC tags. The indication circuit generates property information with respect to the antenna unit.

摘要： A voltage level detecting device is provided including comparators, a detection circuit, a trigger signal output circuit, a delayed control signal output circuit, a delayed comparison result signal output circuit, a circuit, and a control circuit. The comparators compare a voltage level of an input signal with each threshold level to generate and output a comparison result signal. The detection circuit detects a change in the comparison result signal and outputs a detection signal. The trigger signal output circuit outputs a trigger signal when a predetermined time has elapsed. The delayed control signal output circuit outputs a delayed control signal indicating a value of the control signal. The delayed comparison result signal output circuit outputs a delayed comparison result signal indicating the value of the comparison result signal. The circuit outputs a voltage level signal indicating a voltage level of the input signal. The control circuit outputs the control signal.

摘要： A discharge waveform generating device includes a timing reference generation circuit, a timing adjustment circuit, a waveform pattern generation circuit, and a timing correction circuit. The timing reference generation circuit generates a discharge timing for generating, from image data, a discharge waveform of ink to print the image data, based on a line synchronization signal for synchronizing discharge operations of discharge nozzles to discharge ink. The timing adjustment circuit sets an adjustment value of the discharge timing. The waveform pattern generation circuit generates the waveform from the image data, based on outputs of the timing reference generation circuit and the timing adjustment circuit. The timing correction circuit causes the waveform pattern generation circuit to start generation of the waveform in a condition in which the waveform pattern generation circuit has not finished the generation of the waveform when the timing reference generation circuit receives the line synchronization signal.
