摘要： PURPOSE:To prevent chattering with simple constitution, by using a part of a flip-flop for clock frequency division in common for the timing of output flip- flop set and reset. CONSTITUTION:In inputting ''1'' to an input terminal IN, an output of an AND circuit G11 goes to ''1'' and FFs 6-10 start counting. When the output of a flip- flop FF7 goes to ''1'', ''1'' is outputted at an output terminal OUT. Since the output of an NAND circuit G17 goes to ''0'' during this time, an output of an OR circuit G13 goes to ''0'' to clear the FFs 6-10. When a contact is opened, a circuit G12 outputs ''1'', the FFs 6-10 start counting, the FF10 outputs ''1'', the output terminal OUT goes to ''0'', the output of the NAND circuit goes to ''1'' for the preparation of the next input. The chattering of the contact is recovered during this operation time.

摘要： PURPOSE:To form a push-button dial which operates stably even for long distance subscribers, by using the simple key switch input circuit of a one-make contact constitution by the key input circuit. CONSTITUTION:The low group is composed of one NPN transistor TR1, and the high group is composed of the PNP transistor TR2 and one NPN transistor TR3. The low-group contact of frequency switch fSW and the high-group contact of fSW are connected to the base of TR1 and the base of TR2 respectively. When the contact of fSW is closed, a current is flowed through the path of the emitter of TR2 the base the contact of fSW the base of TR1 the emitter, and three transistors of both groups are turned on, and contact information at both ends is obtained from terminals L1 and H1. Since the contact of fSW is inserted between base of TRs 1 and 2, key input circuit 3 can be operated even if the contact resistance of the contact of fSW.

摘要： PURPOSE:To perform service such as calculation and seat reservation, by performing communication dependently upon a multifrequency dial signal after connection of the line to the other-party terminal dependent upon a DC dial pulse signal. CONSTITUTION:Switches 21 and 22 to control electric power to dial pulse (DP) generator 3 and multifrequency signal (MF) generator 4 are normally turned off. When MF generator 4 is operating, switch 23 to disconnect transmitter 14 from the telephone set circuit is normally turned on. When dial switch 1 is depressed after off-hook, switch 21 is turned on, and transistor TR17 is turned on, and the DP signal is transmitted by turning-on and off of TR16. When the incoming terminal responds, switches 22 and 23 are turned on and off respectively, and MF is transmitted from MF generating circuit 4, and switch 21 is turned off still, and DP generating circuit 3 is not operated. As a result, various service between terminals is possible with the same dial switch.

摘要： PURPOSE:To secure stability in linear operation in dialing by performing side-tone improvement of a low frequency in calling, by connecting a transmitter and the 2nd balancing circuit to the break contact of a push-button dial common switch via diodes. CONSTITUTION:To transmitter T and the 2nd balancing circuit ZN2, diodes D1 and D2 are connected respectively and common connection terminal P2 of diodes D1 and D2 is connected to break contact B of push-button dial common switch SW. As a result, a side tone of a low frequency is improved by the 2nd balancing circuit ZN2 in calling as well as a conventional telephone set circuit and the 2nd balancing circuit ZN2 large in current bleed is disconnected even from a long distance line in dialing, thereby securing stability in linear operation. Further, transmitter T is electrically disconnected from the 2nd balancing circuit ZN2 by diodes D1 and D2, so that the level variation of a dial signal due to a change in the resistance of transmitter T will be inhibited.

摘要： PROBLEM TO BE SOLVED: To obtain an optimum transmission signal by changing the mixing ratio of two frequency band signals comprising a high frequency component and a low frequency component of a signal picked up by an air conduction microphone to a frequency band signal including the low frequency component of a signal picked up by a bone conduction microphone and putting together the three frequency band signals on the basis of an estimated surrounding noise level. SOLUTION: Filters 6, 7 receive a signal picked up by an air conduction microphone 1 to separate the signal into two frequency band signals consisting of a high frequency component whose frequency is 1 kHz or over and a low frequency component whose frequency is lower than 1 kHz. A filter 8 receiving a signal picked up by a bone conduction microphone 2 extracts a frequency band signal including a low frequency component whose frequency is 1 kHz or below. A transmission state detection section 9 and a control information provision section 10 estimate a surrounding noise level from the signal picked up by the air conduction microphone to control level control sections 11, 12. Control section 11, 12 change the mixing ratio of the high frequency band signal from the filter 6 to each of the low frequency band signals from filters 7, 8 and a mixing circuit 13 mixes the signals at this mixing rate. Thus, a proper transmission signal to a noise level can be obtained.

摘要： PROBLEM TO BE SOLVED: To attain a quick response in emergency by allowing a communication terminal in a PHS system to operate transmission, call incoming, holding, or transfer to a prescribed telephone number based on information from the control part of a mobile body, i.e., an automobile. SOLUTION: A terminal 1 loaded on a mobile body intermittently transmits and receives position information. A time band necessary for this is about 10 seconds, and a required time when the mobile body moves at a speed which is 60 km/hour from one edge to the other edge related with the umbrella of radio waves whose radius is 150 m is about 18 seconds, and position information can be captured and recorded. Then, a PHS position information service terminal 1 is attached to the upper part of an A pillar, dash board, or rear shelf or the like of an automobile. This terminal 1 is provided with a car network connector site 15 for communicating with the control network of the automobile. Thus, for example, at the time of receiving the operation signal of an air back, it is possible to immediately call 119, and to attain the emergency report of accident information such as an accident occurrence place.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized telephone set with superior carrying performance and few operation buttons. SOLUTION: When a 'voice' button is depressed in an incoming call waiting state, the processing transits to a voice repertory dial. A voice-recognition section 110 recognizes a received voice and reports a registration number object of a destination to a control section 107 by referring to a dictionary memory 111. When the 'voice' button is depressed twice in the incoming call waiting state, the processing transits to a voice dial state. The telephone number is entered digit by digit through the entered voice or the depression of a 'function' button 105. When a voice input is received, the voice-recognition section 110 recognizes the voice signal and reports a numeral code object to the control section 107 by referring to the dictionary memory 111. The control section 107 displays the numeral and moves a cursors to a next digit. In the case of depression of the 'function' button 105, a numeral is sequentially displayed during the depression, and the display is confirmed when the depression is stopped to move the cursor to the next digit. When a 'speech' button is depressed, dialing is made by the registration number or by a numeral string through one-digit entry, so as to attain a speech.

摘要： PROBLEM TO BE SOLVED: To facilitate the enhancement of a caller database by utilizing a caller telephone number informed by a caller telephone number display service. SOLUTION: A caller information retrieval section 105 retrieves a caller telephone number from the caller database 106, based on the caller telephone number informed at the arrival of an incoming call, land a caller information control section 104 allows a display device 107 to display whether or not the caller telephone number is registered, when the caller telephone number is not registered in the caller database 106. In the case that the caller telephone number is registered, caller information is entered by a caller information entry section 110 and a caller information registration section 111 registers the information to the caller database 106, and the registered information is used for succeeding incoming calls.
