Title: Automatic change-over mechanism for inverter
Inventor: YAMADA TETSUO
IPC: H02P1/58
Filed: 1986-04-21
Abstract: PURPOSE:To shorten a time up to synchronization, by keeping a deviation between the frequency of an auxiliary running inverter and the frequency of a running inverter, and by processing the synchronization. CONSTITUTION:First, by the output of an auxiliary inverter 3, motors 6a-6c are started. In this case, if the frequency f1 of an auxiliary running inverter control section 4 is in the range of D-T/2 of the cycle T of the frequency of a running inverter control section 2 through a cycle detecting means 7, frequency deviation  f is added to the frequency f1 of the auxiliary running inverter control section 4 by an adding means 9, and if it is in the range of T/2-T, the frequency deviation  f is subtracted from the frequency f1 by a subtracting means 10. By a synchronization discriminating means 11, the synchronization is discriminated when the frequency deviation  f equals or approximates zero, and the auxiliary running inverter 3 is changed over to a running inverter 1.

Filed: 1983-05-25
Abstract: PURPOSE:To shorten a preheating time greatly and improve the reliability of a temperature sensor by installing a plate type heating body in parallel to a guide member for a couple of fixing rolls, and providing the temperature sensor the surface of the heating body. CONSTITUTION:The plate type heating body 12 is arranged in parallel to the paper feed guide 4 for the fixing roll couple, and the temperature sensor 13 is fitted to its surface. When a supporting body 5 holding a toner image is conveyed, the heating body 12 generates heat to heat the toner image 6 to temperature above a softening point, so excellent fixation is performed. Then, the heat capacity set electric power of the heating body 12 are approximated to the characteristics of a heat roll 1 to control the surface temperature of the heat roll 1 through the sensor 13. Thus, the preheating time is shortened greatly and no toner sticks to the sensor 13, whose reliability is therefore improved.
