    摘要: A noise canceller includes an input terminal for receiving an input signal containing a received signal and a first noise signal generated by a noise source, a first delay unit for delaying the input signal, a pick-up antenna for receiving a second noise signal generated by the noise source, a cancel-signal generator for generating a noise-canceling signal based on the second noise signal, and a combiner for combining the delayed input signal and the noise-canceling signal so as to cancel the first noise signal contained in the input signal, and outputting the received signal. The noise canceller can include a second delay unit for delaying the second signal instead of the first delay unit or in addition to the first delay unit. This noise canceller cancels the noise signal generated by the noise source, thereby providing an electronic device having a preferable receiving sensitivity.

    摘要: The wire electric-discharge machining apparatus is provided with an inter-pole voltage correction unit 109 which corrects a voltage corresponding to an inter-pole voltage according to a correction coefficient which increases with an elongation of discharge stop time. A corrected voltage corresponding to the inter-pole voltage output from the inter-pole voltage correction unit 109 is given to a control unit 106 to allow a wire electrode 101 and a workpiece 102 to relatively move according to the corrected voltage corresponding to the inter-pole voltage.

    摘要: A high-frequency power source device includes switching element groups having a configuration in which a plurality of switching elements turned on/off cyclically are connected in parallel. One parallel connection terminal of the switching element group is connected to a positive electrode terminal of a DC power source, and one parallel connection terminal of the switching element group is connected to a negative electrode terminal of the DC power source. Respective other parallel connection terminals of the switching element groups are connected via a reactor. A pulse voltage that appears at opposite ends of the reactor due to a cyclic on/off operation of the switching element groups is applied to a load through a coaxial cable and a matching circuit.
