摘要： A radio communication apparatus comprises an analog I/Q signal generator, a digital demodulator, and an interference wave suppression control block. The interference wave suppression block detects a gain difference between an in-phase component and a double quadrature component, based on an input and output signals of a low pass filter in the digital demodulator and the output of the double quadrature mixer, and controls a reference voltage of an A/D converter in the digital demodulator. Therefore, it is possible to reduce the gain difference of the in-phase component and the quadrature component, and to effectively eliminate an interference wave mixed in a base band signal. Furthermore, a radio communication apparatus according to the present invention comprises an antenna input block, a reception block, a transmission block, and an in/out block. Because a frequency when sending data is equal to the frequency when receiving data, it is possible to quickly change transmission and reception. Accordingly, it is possible to effectively use time-slots and transfer data at high speed.

摘要： A heating apparatus includes a heater 6 which includes a first heating conductor pattern 1, a second heating conductor patterns 2 and an elongated plate-shaped member 3 made of heat-resistive and insulated material. The first heating conductor pattern 1 is disposed in the central portion in a longitudinal direction of the plate-shaped member 3. The second heating conductor patterns are disposed in both end portions of the plate-shaped member in the longitudinal direction. The first heating conductor pattern 1 and the second heating conductor patterns 2 are independently controlled their temperature. Current is first fed to the first heating conductor pattern 1, and the current feeding is stopped, and current is then fed to the second heating conductor patterns 2. Accordingly, the protective member placed on and along the heater 6 is gradually heated from the center to both ends.

摘要： In radiocommunication apparatus, two downconverters (41, 42) for use in reception system each heterodyne their respective received RF signal to an intermediate frequency. One of the downconverters employs a local signal generated by a synthesizer (19), and the other employs a signal obtained by dividing the frequency of the local signal by a factor of N. Two upconverters (161, 162) for use in transmission system each convert their respective input transmit signal to a transmit RF signal. One of the upconverters employs a local signal generated by the synthesizer (19) and the other employs a signal obtained by dividing the frequency of the local signal by a factor of N.

摘要： A channel-selecting apparatus in which is designed to determine the oscillation frequencies of a local oscillator and/or the tuning frequencies of a radio-frequency amplifier for all channels by varying analogue dc voltages being applied to a frequency control element such as a variable capacitance diode included in the oscillator and/or the amplifier in accordance with channel selective operation. Digital memory devices are provided each of which previously stores digital information representing the different predetermined analogue voltages assigned to all the channels being applied to the frequency control element. Digital information stored in the memory devices is read out upon selective operation of any of channel selection switches each coupled with the corresponding one of bistable multivibrators. A series of digital signals thus obtained are supplied to the frequency control element after being converted into a predetermined analogue voltage for the selected channel by a digital-to-analogue converter, whereby any of all the channels by selective operation of any of the channel selection switches can be selected.An automatic channel selection only for the channels now on the air is further effected by a function switch and a clock pulse oscillator designed to initiate the supply of shift or clock pulses to the bistable multivibrators collectively constituting a shift register upon operation of the function switch and terminate the supply upon reception of a first broadcasting wave after the function switch is manipulated.
