摘要： PURPOSE:To prevent the production of pop noise at reselection of channel of a receiver having a lock circuit, by providing a means to detect the voltage change when a local oscillating frequency is out of lock and to operate a voice muting circuit. CONSTITUTION:With a receiver having a sampling quartz lock circuit, a means which detects the change in the voltage when a local oscillating frequency is locked to a prescribed frequency and unlocked to operate a voice muting circuit 26, is provided. For example, from a gate driving circut 18' in the said lock circuit provided for an FM receiver, the change in the voltage when a local oscillator is unlocked, is picked up. Further, this output is given to the voice muting circuit 26 via a lock state display circuit 24 via a muting control circuit 25 to mute a low-frequency amplifier circuit 23.

摘要： PURPOSE:To smoothly advance a conversation by stopping reproducing a first response message and continuously reproducing a second response message when off-hook is detected to eliminate the interruption of a response message. CONSTITUTION:When call incoming is detected by a call incoming detection part 2, first response message data stored in a first response message storage part 7 are read out and outputted to a voice synthesizing part 10, and the synthesized first response message is transmitted. Next, when a hook detection part 30 detects the execution of off-hook while the first response message is transmitted, the output of the first response message to the synthesizing part 10 is stopped. Continuously, second response message data stored in a second message storage part 8 are read out, and the second response message synthesized into a voice signal by the synthesizing part 10 is transmitted. Afterwards, when a signal detection part 11 detects a signal showing the end of the second response message, a transmitter/receiver is connected to a line, and a speaking state is provided.

摘要： PURPOSE:To use parts for different destinations in common by setting a control circuit to a first or second reception mode based on the control signal from a signal supply means detecting circuit. CONSTITUTION:When the first control signal is supplied from a detecting circuit 22, a control circuit 16 outputs a first reference signal having a first oscillation frequency from a reference oscillator 6 and is set to the first reception mode in which continuous frequency division ratios and only a prescribed frequency division ratio are selectively set to a programmable frequency divider 5 with respect to the FM band and the TV low band respectively. When the second control signal is supplied from the detecting circuit 22, the control circuit 16 outputs a second reference signal having a second oscillation frequency from the reference oscillator 6 and is set the second reception mode in which continuous frequency division ratios are set to the programmable frequency divider 5 throughout the FM band and TV low band. Thus, parts can be used to different destinations in common.

摘要： PURPOSE:To surely detect a power failure state, by setting a controller at a backup state based on the state of a signal supplied from a circuit to the controller. CONSTITUTION:When a power source switch 20 is turned off and an input to the inhibit terminal 22 of the controller 20 goes to an L level, the controller 20 decides the state of a stereo display signal supplied to a stereo display signal input terminal 21. In other words, the operation of a stereo demodulation circuit 24 is disabled by turning off the switch 29, and no stereo display signal is outputted. And when the power failure state is generated at this time, a backup power source +B2 is supplied to the stereo display signal input terminal 21 of the controller 20 via a resistor 34. Also, since the input to the stereo display signal input terminal 21 of the controller 20 goes to the L level in the power failure state, the clocking, for example, of one minute by a clock circuit is decided. And, when it is clocked at the clock circuit, the controller 20 is set at the backup state.

摘要： PURPOSE:To make a channel reselection operation unnecessary, by leading an oscillation frequency into a capture range forcedly for switching of a function change-over switch, electric power resupply, and so on. CONSTITUTION:The output terminal of gate transistor TrQ3 is connected to one input terminal of voltage comparator OP1, which constitutes an LPF, through resistance R2 to lead the output from the FM detector, which is not shown in the figure, to the input side of voltage comparator OP2. Two-system control circuits 9 and 10 which are provided in the output side of comparator OP2 and generate outputs of levels opposite to each other for the output from the tuning center point are connected to the input terminal of TrQ3, and capacitor C4 which is charged for switching of switches such as function change-over switch 15 and power source switch S1' and flows a current to TrQ3 in the charging time is provided at the control terminal of TrQ3. As a result, the oscillation frequency can be led into the capture range forcedly for switching of switch 15 and power resupply to make the channel reselection operation unnecessary.

摘要： PURPOSE:To simply operate remotely a controlled equipment operated by a remote control transmitter from a caller telephone set through a called telephone set and to simultaneously confirm the operating content in the caller telephone set. CONSTITUTION:A called telephone set 4 stores a remote control signal from a remote control transmitter 2 in response to various operations of a controlled equipment 1 in reference to a key signal set to each of various operations and the stored remote control signal is sent to the controlled equipment 1 in response to a key signal sent from a caller telephone set 11. The controlled equipment returns a reply signal representing the content of the operation to the called party telephone set 4 together with the operation of a remote control signal from the called telephone set 4 and the called telephone set 4 sends the operating content of the controlled device 1 to the caller telephone set 11 in voice.
