Title: Control system for subscriber's circuit
Inventor: AIZAWA TAKEJI
IPC: H04Q3/72
Filed: 1980-04-28
Abstract: PURPOSE:To prevent the high and dry state from being released erroneously, by setting the period from release of the cut-off state of the subscribers circuit to the next scanning of the corresponding subscriber line, to the subscriber scanning period or less, when the cur-off state of the subscriber's circuit is released. CONSTITUTION:When instruction decoder part ODRDEC receives release instruction of the cut-off state, the FF and the TMF are set by the signal from timing circuit part TIMING. Subscriber scanning counter part LSCNCNT generates scanning line driving information. Collating circuit part MATCH collates subscriber position information of information receiving part PSWINF with scanning line driving information, and if they coincide with each other, this circuit part MATCH transmits the output. This output and the AND output of circuit part TMF instruct the release of the cut-off state of subscriber's circuit LC. Since the cut-off contact is released just after the subscriber scanning device completes scanning, the next scanning result becomes normal.

Abstract: PURPOSE:To attempt rapid red-heating of the tip of a heater and control its peak temperature and saturation temperature appropriately by constituting as one body a heat generating section consisting of conductive ceramic material and a control section with different positive resistance temperature coefficients and exposing the heat generating section to the surface of the heater. CONSTITUTION:A heat generating section 20 is exposed to the outer surface of a heater 11 and a control section 21 is incorporated in the heat generating section. A voltage is applied from an outer connection terminal 14 via a metallic wire 16 and an electrode 15 to the heat generating section of the heater 11 and a control section 21. Then, the voltage is divided among the heat generating section 20 and the control section 21 in proportion to their ratio of electric resistance, applying a larger voltage to the heat generating section 20 than to the control section 21. Accord ingly the heat generating section 20 has a larger electric power density relative to the control section, making the heat generating section 20 at the tip of the heater 11 generate heat rapidly. As the side of the control section 21 generates heat, its resistance increases, changing the voltage applied to the heat generating section 20 and the control section 21, and the application of voltage to the heat generating section is thereby controlled and its temperature is saturated at about 850 deg.C after it has reached the peak temperature of about 1,200 deg.C. Its overheating can be, therefore, avoided.
