摘要： PURPOSE:To let a user know incoming with regard to radio-coupled detephone stes, by providing incoming display at a base station in case that even after an incoming signal is sent to a mobile telephone set in response to the incoming, no answer is made. CONSTITUTION:On detecting incoming signal (a), base station 3 sends incoming signal (d) out to moible telephone set 6. Answer signal (i) is not received in case that telephone set 6 can be answer because of installation in an electric field of weak reception intensity, etc. If answer signal (i) is not detected for a fixed period, no-answer detecting circuit 15 sends signal (g) out and drives incoming display unit 16 at the side of base station unit 3.

摘要： PURPOSE:To obtain a dial confirmation tone control unit for the radio telephone equipment which can ensure the dial confirmation tone of a proper level by lowering the gain of the receiver voice amplifier circuit of the terminal telephone set at the dial operating time. CONSTITUTION:With operation of the dial, dial switch 16 operates to generate the dial tone. This dial tone is transmitted 11 and then received 6 at wire terminal unit A to be led to wire transmission line 1. Part of the dial tone is transmitted 4 Via hybrid circuit 2 and then received 7 at terminal telephone set B to be led to receiver 10 after amplification 8 and 9. At this instant, control circuit 17 is actuated by dial switch 16 to lower the gain of voice amplifier circuit 9. Thus, the dial tone (confirmation tone) entering receiver 10 features a proper level.

摘要： PURPOSE:To make an automatic check on the intensity of a received electric field by at least one of a master device and a telephone set when a radio telephone set is not in use, by providing a controlling means for signals of the master device and radio telephone set and a state display means for the radio telephone set. CONSTITUTION:The signal control part 12 of a master device 10 when enqueued sends a calling signal automatically and the reception level of a transmitted radio wave, modulated by an answer signal to said signal, from a radio telephone set 30 is detected. When the reception level is below a prescribed one, the detection that the telephone set 30 is not within a communication range is performed and if the answer signal from the telephone set 30 is stopped in a calling signal transmission period, that is detected to detect the drop in power voltage of the telephone set 30. The signal control part 33 of the telephone set 30, on the other hand, detects its drop in power voltage and sends an answer signal to the device 10 by receiving the calling signal from the device 10 in this case; when no call signal is sent from the device 10 even a prescribed time later, that is detected to stop the transmission of the answer signal.

摘要： PURPOSE:To enable detection with sure discrimination of call-out signal from other signals, by signal processing through the differentiation of callout signal. CONSTITUTION:When callout signal voltage appears between the input terminals L1 and L2, it is differentiated a differentiation circuit 1, the current of a half wave flows to a light emitting diode 5 for illumination and a current flows to a phototransistor 6, the signal appeared at the collector is converted into binary signal at wave shape circuit 9 to obtain comparatively wide pulse train at point d, and when this is integrated at an integration circuit 10, the level corresponding to the pulse width is obtained. By discriminating the voltage level at a level discrimination circuit 15, the call-out signal is detected. When the dial signal is input from the telephone set connected in parallel, the maximum value of the differentiating current at the differentiation circuit 1 is greater than the call-out signal, but since the width is narrow, then the output of the wave shape circuit 9 is narrow, and since the output level of an integrating circuit 15 is smaller than the call-out signal, no detection output is appeared.

摘要： PURPOSE:To simplify the constitution of the incoming-call display part of a mobile station by transmitting a calling signal, synchronizing with a calling signal from a switchboard, from a base station to the mobile station after a radio circuit is connected with regard to radio-coupled telephone sets. CONSTITUTION:A calling signal, once sent out of switchboard 3, is detected by calling signal detecting circuit 11 and at the same time, control circuit 12 is put into operation to generate tone signals f1 and f2. At mobile station 2, detectors 23 and 24 detect signals f1 and f2 and control circuit 29 sends tone signal f3 to base station 1. On receiving signal f3, base station 1 stops the transmission of signal f2. Oscillator 13 generates signal f1 synchronizing with the calling signal from switchboard 3. Through detector 23 and AND gate 27, this signal puts incoming-call display unit (bell) 28 into operation. Therefore, the need for an oscillator for intermittence at the station 2 side is eliminated and bells of stations 1 and 2 can be put into operation synchronizing with each other.

摘要： PURPOSE:To transfer the information intuitively by selectively reading out the information stored in a storage circuit after being digitally processed in advance according to the state of devices detected and displaying it with voice, video and printing. CONSTITUTION:The state of various monitored items of a device 11 to be monitored is transmitted to a detection circuit 20 by lines (a), (b).... A power supply is transmitted with the line (a) and a voltage drop is detected at the circuit 20, then it is transmitted to a control circuit 21 to control a memory 22 and transmit a switching signal to a selector 23 via a line y. Information relating to a voltage is selected out from the information digitized and stored in the memory 22 in advance, it is transmitted to a decoding circuit 12 via a line x and a selector switch 23 for analog processing and displaying audibly with a speaker 14 via an amplifier 13. Video and printing can be made in place of the speaker 14 and the memory 22. Thus, the state of the device to be monitored can be displayed intuitively.

摘要： PURPOSE:To keep constant the distance between an antenna substrate and reflecting plate without reference to external force while minimizing the thickness size and weight, by bonding metal foil to one side of a dielectric plate and by fixing the other side to the antenna substrate to using the above-mentioned metal foil as the reflecting plate. CONSTITUTION:On one side of antenna substrate 1 made of a dielectric, earth conductor film 3 with slot 2 is formed and on the other side, strip conductor 4 is further formed to constitute a microstrip feed type slot antenna. Then, metal foil 8 is bonded to one side of dielectric 7 similar to antenna substrate 1 and face 7a of dielectric plate 7 where metal foil 8 does not reside is fixed on either face of antenna substrate 1, e.g. earth conductor film 3, thereby using metal foil 8 as the reflecting plate.
