摘要： PURPOSE:To record an external message before a line is open by a holding warning by devising the telephone set such that a message of the opposite party after a holding end notice is outputted as a message of an automatic message recorder. CONSTITUTION:When a holding time exceeds a prescribed time, a holding tone from a holding tone output section 2 is stopped, then the holding is forcibly finished, then a holding end notice message output section 6 or a message recording/reproduction section 7 outputs a message representing the recording of the message to a telephone line 9. Then the message of the opposite party is recorded in the message recording/reproduction section 7 as the usual message for the automatic answering telephone and the holding is finished at the end of talking and the line is open.

摘要： PURPOSE:To improve the maintenance performance by revising a transmission level stored in an EEROM in response to a DTMF signal coming during talking. CONSTITUTION:A transmission level to a line is stored in an EEROM 8. A controller 6 reads a transmission level from the EEROM 8 at, e.g. speech start. The controller 6 gives a command to an electronic volume 7 so as to obtain a read transmission level to set a transmission level to a line. As a result, the transmission is executed from the transmission level stored in the EEROM 8. Moreover, when a DTMF signal is received by a DTMF receiver 5 during talking, the controller 6 executes the operation in response to the kind of the received DTMF signal. Furthermore, when the received DTMF signal is a command to increase the transmission level, a high level is commanded to the electronic volume 7 and when the received DTMF signal is a command to decrease the transmission level, a low level is commanded to the electronic volume 7.

摘要： PURPOSE:To reduce a sense of displeasure due to noise at a reception side by increasing an amplification factor gradually from a lower amplification factor than a normal amplification factor and selecting a control signal at a point of time of reception when the control signal is sent in succession to a voice through one and the same channel. CONSTITUTION:A total control section 23 sets an amplification factor of a variable amplifier 12 to a minimum value when a transmission section 21 sends a control signal used between radio equipments while the transmission section 21 outputs a voice signal to a reception section 22 and allows the transmission section 21 to send an amplifier control signal. When no reply comes from the reception section 22 within a prescribed time, the amplification factor of the amplifier 12 is stepwise increased and it is repeated till a reply signal is received.

摘要： PURPOSE:To attain picture communication in matching with communication with different aspect ratio between the sender side and the receiver side by providing a correction process correcting a picture data to either the transmission process or the reception process. CONSTITUTION:The picture data of both ends in the horizontal direction is deleted in response to the aspect ratio of the receiver side equipment, a fetch picture data M is extracted and the fetch picture data M is subject to picture element interpolation by a prescribed rule to generate a corrected picture data M' having a horizontal standard picture element number. Thus, the longitudinal elongation of the picture data displayed on the picture display section of the receiver side is prevented even at the communication between different types of equipments where the sender side has a larger lateral size and the receiver side has a larger longitudinal size in their aspect ratios and the matching of the display pictures between the sender side and the receiver side is attained.

摘要： PROBLEM TO BE SOLVED: To enhance the utilizing efficiency of a master set and to extend a range of location of a slave set to outdoor by providing a means selecting communication and an outdoor repeater. SOLUTION: An outer conductor 77 and its skirt 78 of an outdoor repeater 36 have a water-proof structure. A call signal from a slave set A37 is received by an antenna 6 of the outdoor repeater 36, amplified and detected by a receiver A7. An ID number and a destination number in a call signal are decoded by a control circuit A11 and sent to a control circuit B17 via a line changeover circuit 38. A dialing from the line changeover circuit 38 to a telephone line 39 is allowed by the control circuit B17 when the ID number received from the slave set A37 indicates a specific registration number for external dialing and the dialing to an external device is made. In the case of a usual registration number, the line changeover circuit 38 and a handset 40 are connected to make a call to a master set 35.

摘要： PURPOSE: To provide a battery driven portable information equipment which determines a voltage for generating a battery rest alarm according to whether the power consumption of a main body is large or small or the kind of a battery and inhibits the battery rest alarm from being generated according to environmental conditions. CONSTITUTION: On the basis of the power consumption of the main body 10 which is inputted from a keyboard 34 or automatically measured by a battery voltage monitoring microcomputer 20, an optimum conversion table 131 which converts a battery rest alarm time into a battery rest alarm voltage is selected. Then the main body 10 generates an address of the conversion table 131 on the basis of a battery rest alarm time inputted from the keyboard 34 and set in a register 191. Then the microcomputer 20 compares the battery rest alarm voltage from the conversion table 131 with the rest voltage of the battery which is actually measured and generates an alarm by a speaker 31 when the measured value reaches the battery rest alarm voltage from the conversion table 131.
