摘要： PURPOSE:To prevent a talking line from being in use continuously by detecting that a talking is finished and the charging is started and interrupting the ratio line based on the detected output. CONSTITUTION:If an end of talking switch 7 is left unoperated at the end of talking and a slave set 3 is connected to charging terminals 19A, 19B of a master set 2, a detection circuit 21 detects the start of charging. Then a control circuit 22 cuts the power of, e.g., a transmitter by using the detection output so as to interrupt the radio wave of a transmitter 10. While a receiver 5 of a radiotelephony set 3 detects the interruption of radio wave and a control circuit 23 interrupts the radio wave from the transmitter 6 by using the output, restores to the standby state thereby preventing the continuous transmission. In this case, the circuit detecting the interrupted radio wave of the receiver 5 is constituted by a conventional noise squelch or carrier squelch circuit.

摘要： PURPOSE:To improve security capability against theft, etc. by holding a small electronic device such as a vehicle-mounted and portable wireless equipments in a holding case by engagement retention effected by mere insertion and by making it possible to release the engagement retention only when a specified compound actions are made within a specified period of time. CONSTITUTION:When a housing 11 of a small electronic device is inserted into a holding case 12 while being guided with a guide rib 15, the housing 11 descends and the bottom surface of the housing 11 makes an upper slope 17c of a locking claw 17a of a hooked part 17 turn counterclockwise resisting against the resilience of a spring 25. The housing 11 is locked in the position where the locking claw engages with a locking groove 16. Here, a small- diametered locking groove 33b of a locking plate 33 resiliently forced by a spring 38 is fitted with a connection part 32 of a retention bar 18 to bring the lock under a locked condition. This locking plate 33 is so made that it is displaced to the direction of releasing the locking by exciting a fixed solenoid 37 through a control means only when specified compound actions are made within a specified period of time.

摘要： PURPOSE:To attain the hooking operation simply in an optional timing by closing a line relay when a base station receives an off-hook signal at calling so as to bring the state into a talking state (off-hook state) and opening the line relay only while the off-hook signal is received in the talking state. CONSTITUTION:A control section 13 of a mobile station 1 has a state storage section storing whether the state is in the talking state (off-hook state) or not. When an off-hook switch 14 is depressed while the state storage part is in the non-talking state, said state storage part is set to the talking state. On the other hand, a control part 23 of a base station 2 has a state storage part storing whether the state is in the talking state or not. When the state storage part represents the non-talking state and the signal detection part 22 detects the off-hook signal, the control part 23 closes the line relay 25 to set the said state storage part into the talking state. When the state storage part represents the talking state and the signal detection part 22 detects the off-hook signal, while the control part 23 detects the off-hook signal, the line relay 25 is opened.

摘要： PURPOSE:To prevent an undesired dial signal or data signal from being sent to an opposite side during talking by sending a dial signal based on a stored destination number data in a memory according to a prescribed operation during prescribed time counted by a timer means. CONSTITUTION:A call detection circuit 29 supervises always the dialing operation and when a call is detected, and timer starts its operation. A control circuit 9 sends a PB tone from a PB tone oscillation circuit 13 to a wired telephone line 15 when a destination number is inputted to connect the line to the opposite side. When a redialing switch 7 is depressed and the destination data is stored in a memory 5, an on-signal of the switch 7 is sent to the control circuit 9 via a gate 33 to attain redialing. When a prescribed time elapses, however, due to the busy state of the opposite party, since the timer 31 times up, even when the redial switch 7 is operated, the gate 33 is closed and no redialing is executed.

摘要： PURPOSE:To expand remarkably the service function of a professional radio and a simple radio by using a radio call station and a radio reception station so as to couple a radio equipment with a telephone circuit network and sending signal information from the radio equipment to a subscriber by the radio reception station. CONSTITUTION:In calling a radio equipment 7 from a subscriber 1, a central equipment 3 is called at first to inform a call number. The equipment 3 calls the radio equipment 7 via a radio call station 5. The equipment 3 retrieves a file of a storage device 4 to recognize a frequency (f) used by the radio equipment 7 and the frequency of the radio reception station 6 is to a frequency (f). The ratio equipment 7 detects a call signal from the call station 5 and when the signal is coincident with its own call number, a signal including its own position information or the like is sent. The reception station 6 receives the signal and transfers the information included in the reception signal to the equipment 3. The equipment 3 gives the information to the subscriber 1. Thus, the service function of the professional radio and the simple radio is expanded remarkably.
