Title: Fault current detecting circuit
Inventor: HAYASE TAKAYUKI
IPC: G01R31/327
Filed: 2009-07-22
Abstract: <P>PROBLEM TO BE SOLVED: To measure a broken fault current at low cost, regarding a fault-current detecting circuit which outputs a voltage equivalent to the fault current to a counter for a cumulative amount of break of a breaker.  <P>SOLUTION: In the fault-current detecting circuit 1, auxiliary current transformers ST1 and ST2 convert the secondary currents of each current transformer in wiring L1 and L3 and supply them to a resistor R0. The resistor R0 converts the current received into a voltage and outputs it. Diodes Di1 and Di3 rectify the output voltage and charge the voltage of a positive electrodes into a capacitor Cp via a resistor R1, and charge the voltage of a negative electrode into a capacitor Cn. The capacitors Cp and Cn discharge electricity, based on a voltage where the voltage of the positive electrode and the voltage of the negative electrode are synthesized. A resistor R2 receives the discharge from the capacitors Cp and Cn, and makes the composited voltage a voltage across itself. A microcontroller detects the voltage of the resistor R2 equivalent to the fault current as a counter for the cumulative amount of break. It can stabilize the voltages of the capacitors Cp and Cn when breakers B1-B3 break currents after occurrence of a fault in a main circuit 2 by adjusting the resistance values of the resistors R1 and R2 and the capacitance values of the capacitors Cp and Cn.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a fixing device that has a simple structure and ensures stable fixing process for a long period of time.  <P>SOLUTION: In operation of the fixing device, a second infrared heater 60 is periodically turned on and off to generate an uneven periodical temperature difference on a fixing film 21. During switching of the second infrared heater 60, a temperature change on the fixing film 21 is detected by a second temperature sensor 41, and a cycle of the temperature change obtained based on the detected results and an on-off cycle of the second infrared heater 60 are compared. If the on-off cycle of the second infrared heater 60 matches the cycle of the temperature change of the fixing film 21 detected by the second temperature sensor 41, the fixing film 21 as a fixing member can be determined to be in a predetermined rotating state. On the contrary, if the fixing film 21 slips, a difference occurs between the on-off cycle of the second infrared heater 60 and the cycle of the temperature change of the fixing film 21 detected by the second temperature sensor 41.  <P>COPYRIGHT: (C)2011,JPO&INPIT
