Abstract: PURPOSE:To achieve the safety of the tape recorder and the improvement of its power consumption by supplying a timer signal and the signal from the tape recorder to a logic circuit, continuing the power supply during feeding of magnetic tape and breaking the power source at the ending of the tape. CONSTITUTION:A radio receiver 7 and a tape recorder 8 are let to stand by operating a power source switch 10, thence a key switch 20 is closed. Next, when a timer signal inputs to terminal 12, the switch 32 of a logic circuit 11 closes to supply power source to the receiver 7 and recorder 8, thereby starting recording. Here, even if the timer goes off, the power supply is continued by the circuit 11 during running of the magnetic tape and the power supply is broken by detecting the opening of the switch 20 owing to ending of the tape running and opening the switch 32. When the recorder 8 is shut off during timer operation, the switch 32 of the circuit 11 is opened to break the power supply. In this way, the accident owing to the pinch roller deformation of the tape recording 8 may be prevented and wasteful power consumption improved.

Abstract: PURPOSE:To prevent the deterioration in the resistance to disturbance by adopting a double balanced type mixer circuit and applying shunt type delay AGC to a reception signal and a local oscillation signal supplied to the mixer circuit thereby extending the range of AGC. CONSTITUTION:When the input level is smaller than a prescribed v1. AGC is applied by an intermediate frequency amplifier 8 and shunt AGC is applied to a reception signal Sr by an AGC circuit 21 when the level is larger than the V1. Moreover, when the input exceeds a prescribed voltage V2, an AGC circuit 22 applies shunt AGC to a local oscillation signal So. Since the shunt AGC is to both the signals Sr, So in a delay form where the start level differs thereby offering the AGC with a wide range. The double balanced mixer circuit is employed and a delay type shunt AGC is applied in this way so as to prevent the deterioration in the resistance to disturbance.

Abstract: PURPOSE:To make it possible to set and change a squelch level simply and accurate ly, by displaying the squelch level visually. CONSTITUTION:The DC voltage (DC voltage corresponding to the receiving input level) dependent upon the automatic gain control signal of intermediate frequency amplifying circuit 5 and reference voltages which correspond to the input signal level of 0dB, 10dB, and 20dB respectively are compared by comparators 21, 27 and 23. When the DC voltage is larger than reference voltages, light emission diodes 25, 31 and 37 are driven by outputs of comparators to display the input level; and when the DC voltage is smaller than the minimum reference voltage (voltage corresponding to the input signal level of 0dB), only light emission diode 19 is driven. Consequently, since the receiving input level can be detected by states of respective light emission diodes, the squelch level corresponding to the input level can be set and changed easily by connection switches 20, 26, 32, and 38.

Abstract: PURPOSE:To provide accurate position information and to guide an emergency vehicle by providing a GPS receiver or the like outputting current position information and superimposing the current position information onto emergency information and sending the result when the emergency information detected by a detection means is sent. CONSTITUTION:A security terminal equipment 1 consists of a sensor 2, a memory 3, a signal transmission means 4, an input terminal 5 and an output terminal 6. The sensor 2 has a function as a detection means of various information such as temperature, smoke, vibration, gas leakage, illegal intruder, and the memory 3 has a function as a storage means of various information such as position information and transmission signal information. Moreover, a signal transmission means 4 outputs the position information of the security terminal equipment 1 and emergency information such as disaster in a wired system or in a radio wave. Moreover, a GPS receiver 7 outputting current position information is provided and superimposes the current position information onto the emergency information on its transmission and sends the result. Thus, accurate position information is obtained on the occurrence of emergency such as disaster to guide an emergency vehicle.

Abstract: PURPOSE:To allay apprehension by providing a microphone and a speaker for talking so as to allow a called party to recognize that the calling is attained adequately when a call signal is transmitted to the called party or when a call signal is received from the called party respectively. CONSTITUTION:In the operating mode entering the talking state after a trigger signal forming a call signal to a called party of talking is transmitted, the state attaining transmission and reception is adopted in response to a return signal transmitted from the called paty after the transmitted trigger signal T is detected by the called party, and the state is displayed, then the caller recognizes, the state attaining transmission and reception after the transmission of the trigger signal. Further, in the operating mode entering the talking state by receiving the trigger signal forming the call signal from the called party of talking, since the return signal is transmitted automatically in response to the trigger signal from the called party, the called party recognizes the detection of the trigger signal by the return signal.

Abstract: PURPOSE:To improve the operability by displaying a group number and an abbreviated number in response to each operating mode in a personal radio equipment having only one display section equal to the number of digits of the group number. CONSTITUTION:A personal radio equipment provided with a multi-channel access connecting control function by one kind or two kinds of group number setting (signal node or dual mode) is set by setting directly the group number (direct-in mode) or by designating a location storing the group number by an abbreviated number (memory-in mode). A display control section E, in this case, performs the display corresponding to each operating mode such as display of a memory number (1 digit) of a channel memory Mc storing the group number after the section E displays the group number of 5 digits stored in the 1st group number memory M1 to a display section D in a case of the direct-in mode and displays the group number for a prescribed time only in case of the memory-in mode. Then, even if only one display section having the same number of digits as the number of digits of the group number exists, the operability is improved.
