摘要： 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.

摘要： 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.

摘要： 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.

摘要： Demodulator includes reception quality evaluation circuit for evaluating the quality of a received signal by comparison with a first reference value, and outputting an evaluation signal; and driving circuit receiving the evaluation signal. If reception quality evaluation circuit evaluates that the quality of the received signal is acceptable, power supply from driving circuit to DC offset control loop is stopped. This offers a high-frequency receiver that reduces power consumption.

摘要： 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).
