  • Publication number: 20090195701
    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.

  • Publication number: 20080053840
    Abstract: An anode (3) and a cathode (5), interposing a solid polymer film (7), are disposed. While supplying purified water from a supply port (13a) of an anode chamber (13), wherein the anode (3) is disposed, and a supply port (15a) of a cathode chamber (15), wherein the cathode (5) is disposed, direct electric current is applied between the anode (3) and the cathode (5). As a result, ozone-water is discharged from an outlet port (13b) of the anode chamber (13). In such an electrolysis cell (1), a free-standing conductive diamond plate, formed by microwave plasma assisted CVD so as to have a thickness of 0.8 mm, is used as the anode (3). The diamond plate is provided with holes, having a diameter of 1 mm and disposed such that a center distance therebetween becomes 2 mm. Therefore, the electrolysis cell (1) can stably produce ozone without causing exfoliation of the anode (3), even when high voltage and large current are applied between the anode (3) and the cathode (5).

  • Patent number: 7294365
    Abstract: A method of preventing or reducing fogging of a surface of a composite when subjected to humid conditions includes providing a composite with a surface. The composite includes a substrate and a photocatalytic surface layer. The photocatalytic surface layer includes a photocatalyst. The method further includes subjecting the photocatalyst to photoexcitation to render the surface of the composite hydrophilic, wherein, after the photoexcitation, the surface of the composite has a water wettability of less than 10° in terms of the contact angle with water. The method further includes subjecting the composite to humidity that is sufficient to induce fogging of the substrate if the photocatalytic surface layer were absent.

  • Patent number: 7194245
    Abstract: A high-frequency signal receiver includes a mixer having one port for receiving an input signal and another port for receiving an output from a local oscillator, a filter for receiving an output from the mixer, and an output terminal to which an output from the filter is supplied. At least the mixer and the filter are formed of balanced circuits, so that they have high capability of eliminating interference. Distances between the circuits thus can be short. Further, partition plates for shielding the interference are not needed, thus allowing the receiver to be small.

  • Publication number: 20070049228
    Abstract: A high-frequency receiver capable of improving both an interference-resistant characteristic and reception sensitivity is provided. A gain switch control unit includes: a signal level determination unit comparing a gain control voltage of an amplifying circuit with a reference voltage; and a gain switch controller provided between an output terminal of the signal level determination unit and a gain control input terminal provided to an amplifying circuit for gain control. When receiving a signal in a strong electric field area having a high possibility that a strong interference signal exists, a gain of the amplifying circuit is set to be smaller than that in a case of receiving a signal in a weak electric field area by a gain switch signal output from the gain switch controller.
