    摘要: A stereo demodulator circuit comprising at least one noise control unit for performing a noise control responding to an RSSI (reception electric-field intensity) when the RSSI is within a specified range, further comprises an AD converter unit for AD-converting a signal corresponding to the RSSI and a control signal producing unit for producing a control signal for a noise control performed in the noise control unit according to a noise level when the noise level obtained by the AD conversion is within the above described specified range. The control signal producing unit comprises an offset unit for digitally offsetting a signal obtained through the above described AD conversion by a predefined value and truncating lower bits off the offset value by the number of bits in compliance with a grade of the noise control accuracy and outputs the control signal based on the signal obtained from the offset unit.

    摘要: The present invention prevents sound quality from degrading due to a change in electric field intensity or due to multi-path noise. An arithmetic unit subtracts a signal based on the detection signal of multi-path noise whose time constant is specified by a second time constant circuit from a signal based on an RSSI signal whose time constant is specified by a first time constant. An output signal from this arithmetic unit is applied, as a control signal, to a stereo-noise control circuit or the like. This can control the degradation of separation and the like in accordance with multi-path fading to prevent sound quality from degrading.

    摘要: There is provided a receiver not requiring a complicated connection for an operation test and capable of reducing the test time and simplifying the device configuration. An output signal of an oscillator 21 used for generating a reference signal input to a PLL circuit 20 connected to a local oscillator 13 is divided by a divider 24 to generate a test signal contained in a reception band of the AM broadcast. This test signal is input via a switch 25 to a high frequency amplification circuit 11 and an intermediate frequency signal for this test signal is input to a level detector 30. When the AM receiver operates normally, the output of a voltage comparator 31 becomes high level.

    摘要: An FM receiver which can be used by being switched between stereophonic and monophonic, and comprises detecting unit for detecting a received signal, two routes over which a detected signal is transmitted to an output buffer, and a switching unit for selecting either one of the two routes. The two routes consist of a route passing through a stereophonic demodulator unit and a route bypassing the stereophonic demodulator unit; and the switching unit selects either one of the two routes based on a control signal indicating the selection of either one of stereophonic and monophonic, and, when the route bypassing the stereophonic demodulator unit is selected, turns off power supply to the stereophonic demodulator unit based on the above control signal.

    摘要: An FM/AM switch (31) selects either an FM detected signal or an AM detected signal. A capacitor (4) is provided to cut the DC component of the FM detected signal. A low-cut frequency switch (33) selects a resistor designated by a control, signal from among resistors (Ra through Rc). A high-pass filter is constituted by the capacitor (4) and a resistor selected by the low-cut frequency switch (33). The cut-off frequency of this high-pass filter is adjusted by the selection of a resistor.

    摘要: In order to carry out quick and easy changeover of platens of an electrode unit, a shank holder connects a fixed lower electrode with a platen. Further, a movable upper electrode is connected with another platen by the shank, which is held by the shank holder. The shank holder and the shank are integrally connected with each other, and are positioned in such a manner that the electrodes can perform resistance welding. Merely detaching the shank and shank holder from their respective platens allows the desired electrode units to be mounted on, or removed from, a resistance welder without making any position adjustments of the electrodes. Consequently, adjustment of the positions of the electrodes becomes unnecessary, thereby facilitating quicker and easier changeover of electrodes.
