Title: Subscriber circuit
Inventor: HAYASHI TAKAO
IPC: H04M19/00
Filed: 1983-01-12
Abstract: PURPOSE:To obtain a subscriber circuit reducing power consumption on the whole by varying the value of the reference voltage with a monitor output and turning on and off a feeding circuit by the monitor output. CONSTITUTION:When a resistance having smaller than a specific resistance value is connected between circuit connection terminals 8-a and 8-b, the output of an operational amplifier 30 exceeds a reference voltage and the output of a comparator 37 drops to a low level to turn on transistors (TRs)50 and TR60. Therefore, feeding circuits 1 and 2 operate to obtain a specific DC feeding impedance value, supplying currents to circuits (a) and (b). Then, the feeding impedance is switched from high impedance by resistance 80 and 90 to low impedance by the feeding circuits 1 and 2. Then, the voltage between the terminals 8-a and 8-b rises and the output of the amplifier 30 drops. Consequently, the subscriber circuit detects the resistance values of the circuits; the feeding circuits are turned off when the resistance values are larger than a specific value or turned on when the values are smaller than the specific value.

Abstract: PURPOSE:To prevent the extinction of display even if the switch is operated by mistake after the finish of measurement, by prohibiting the operation stop function of the switch during a time when a temp. measured value exceeds a predetermined value. CONSTITUTION:The temp. corresponding to bodily temp. is converted to an electric signal by a temp. sensor 7 while the electric signal is converted to a digital value by an A/D converter 8 to be taken in CPU 9 and stored in a memory 10 as measured temp. data. The max. value of measured temp. is renewed by CPU 9 and the renewal value is held to and stored in the memory 10 to be displayed on a display device 4 as bodily temp. The rising rate of the measured temp. is calculated to judge whether the rising rate became lower than a predetermined value and, when said rising rate becomes lower than the predetermined value, a buzzer 6 for performing information urging the reading of the temp. displayed on the display device 4 as bodily temp. is operated. Further, CPU 9 discriminates that the measured temp. reached the predetermined value or more to prohibit the operation stop function of a switch 5 during a period when the measured temp. exceeds the predetermined value.
