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： A high frequency receiver cancels a plurality of noise signals which are contained in a high frequency signal and outputted from a plurality of noise signal sources. The high frequency receiver cancels the noise signals using a plurality of pick-up noise signals extracted from a plurality of pick-up antennas disposed near the noise signal sources. At least one of the pick-up noise signals is selected in descending order of their effects on the degradation of reception quality, thereby completing noise cancelling in a short time.

摘要： When changeover switch (26) selects the output of L band filter (23), changeover switch (28) is turned off and mixer (29) is operated as an amplifier such that the oscillation frequency of local oscillator (31) is controlled based on data fed to data terminal (37) and a channel selection can be performed in mixer (32). When changeover switch (26) selects the output of V band filter (25), changeover switch (28) is turned on and a channel selection is performed based on data fed to data terminal (37) in mixer (29). With this arrangement, the need for a tuning filter is eliminated and a broadband tuner not requiring manpower for adjustments can be provided.

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).
