    Abstract: PURPOSE:To enable the operator to confirm the operation of a receiver easily by incorporating an electric field intensity detector and control signal generator, and by confirming the normal operation of the receiver with a control signal from the control signal generator. CONSTITUTION:With switch 9 closed at the side of contact 9a, audio frequency amplifying circuit 5 is energized and, when tuned to the frequency of a broadcasting station, to generate signal S1 at the output side of electric field intensity detector 11. If this signal S1 is higher than a prescribed frequency level, the gate of AND circuit 12 is opened and signal S4 appears at its output side. Next, switch 9 is changed over to the side of contact 9b. At this point in time, pulse signal S2 appears at the output of integrating circuit 17. In response to this signal S2, monostable multivibrator 18 outputs signal S3 for a certain time. This signal S3 energizes control signal generator 14 to output signal S5 in response to signal S4 from circuit 12. This signal S5 is supplied to control signal detecting circuit 7 and circuit 5, and circuit 7 generates signal S6 to close relay 8. Therefore, signal S7 is outputted from circuit 5 in response to signal S6.

    Abstract: PURPOSE:To attain the transmission with high efficiency to a stationary satellite while a transmission antenna is fixed by using an azimuth detection means so as to detect that the antenna is directed in the direction of the stationary satellite and using the detecton signal so as to operate the transmission control. CONSTITUTION:A controller ll is provided, to which an azimuth detctor 4 detecting the direction of an automobile 60, that is, the direction of an antenna 40 fixed to the automobile 60 is connected. A comparator 60 detects an output votlage of a DC-DC converter 53, that is, a charging voltage Vc of a capacitor 70 rises at a prescribed voltage Vref (e.g., Vref=50V), and suppied its detection output signal to the controller 11 of the said signal processing unit 10. Then the signal processing unit 10 applies transmission control based on various detection output signals fed from the azimuth detector 4 and the comparator 60. Then the transmission signal is supplied from the signal processing unit 10 and sent to the stationary satellite through an antenna 40.

    Abstract: PURPOSE:To improve the bit compression rate without deteriorating sound quality by applying inverting processing after a difference data subject to bit compression in the unit of blocks is subject to bit expansion. CONSTITUTION:Control information DCO and amplitude information DAM read from a memory are fed to a bit expansion circuit 22 via switches 23, 24, an output from the bit expansion circuit 22 is fed to a local decoder 30, where the processing being inverse to the processing forming a difference data and a reproduced sound data D'AU is outputted from a data output terminal 12. After the difference data (amplitude information DAM) subject to bit compression by the bit compression circuit 21 is subject to bit expansion by the bit expansion circuit 22, the inverse processing to the processing formint the difference data is applied by the local decoder 30, the recovered data DRE obtained by it is fed to a difference processing circuit 6 to form a difference data DDI fed to the bit compression circuit 21. Thus, the error caused at bit compression/ expansion is adsorbed.

    Abstract: PURPOSE:To attain talking with high quality without crosstalk at all times by transmitting/receiving a check signal by an identification code ID, monitoring crosstalk and searching an idle channel when the crosstalk is caused and restarting the talking by an idle channel. CONSTITUTION:When the crosstalk takes place at a point of time t1 and a base unit 2 cannot receive correctly the code ID, the transmission of the code ID from the base unit 2 is stopped as shown in broken lines. Then the reception channel of a signal Sd is changed sequentially by a signal CH from the point of time t1. When the reception channel of the base unit 2 is the new channel of a handset 1 at a point of time t4, the code ID from the handset 1 is received and when the code ID is received, the reception channel of the base unit 2 is fixed to the channel by the signal CH at the succeeding point of time t4. Further, the transmission channel is fixed to the corresponding channel, the transmission of the signal Sd is permitted by a signal TX to send the identification code ID.
