Abstract: Provided is a chemical decontamination method that shortens the decomposition time of a reduction decontamination agent. An oxidization decontamination, a decomposition of an oxidization decontamination agent, and reduction decontamination using an oxalic acid aqueous solution are performed on a target piping of a BWR plant. After that, the oxalic acid is decomposed (S7). That is, a part of the oxalic acid is decomposed by irradiating the oxalic acid aqueous solution with ultraviolet rays upstream of a decomposition device (S8), and Fe3+ in the aqueous solution is converted to Fe2+. Hydrogen peroxide is supplied to the decomposition device (S9). In the decomposition device, the oxalic acid is decomposed by a catalyst and hydrogen peroxide, Fe2+ and hydrogen peroxide react to produce Fe3+ and OH*, and the oxalic acid is decomposed by OH*. A corrosion potential of the aqueous solution flowing out from the decomposition device is measured (S11).

Abstract: Deterioration of television reception sensitivity is prevented by using a noise signal generated from a noise signal source in a portable device. A first case includes a first coupling element connected to one of input parts of the noise-cancelling section in a part of a facing surface thereof. A second case includes a second coupling element supplied with a noise signal from the noise signal source in a part of a facing surface thereof. When the television signal is received with the noise signal source brought in a vicinity of the television receiving antenna, the first and second coupling elements are brought in a vicinity of each other and coupled at a high frequency so as to form a noise signal transmission section. The noise-cancelling section noise-cancels the first noise signal by a second noise signal transmitted to the noise-cancelling section via the noise signal transmission section.

Abstract: 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.

Abstract: A noise canceller of this invention includes a pickup antenna arranged in proximity to a noise signal generation source to extract a noise signal generated by the noise signal generation source, and a noise cancellation unit having a first input for receiving a television signal from a television signal receiving antenna and a second input for receiving the noise signal extracted by the pickup antenna. Herein, the noise cancellation unit removes a noise signal fed from the television signal receiving antenna. Thus, the noise canceller prevents degradation in television signal reception sensitivity due to the noise signal generated by the noise signal generation source.
