Title: Fixing device of copying machine
Inventor: HIRAIKE SHIZUKA
IPC: G05D23/20
Filed: 1990-04-20
Abstract: PURPOSE:To eliminate a waste of power consumption by supplying specific low electric power to heat sources and controlling their drive, and entering a heat mode in a non-copying period in a wait state. CONSTITUTION:After the copying machine is powered on, electric power which holds the fixing device 16 within a specific fixation temperature range is supplied to the heat sources HL2 and HL3, which are controlled to enter a copying ready state. Then the specific low electric power for maintaining the fixing device 16 within the specific fixation temperature range is supplied to the heat source HL1 a specific time later while no copy is taken, thereby placing the copying machine in a preheated state. Consequently, the waste of the power consumption is eliminated and the copying machine is put in the preheated state, so the time of transition from the preheated state to the fixation ready state is shortened.

As the result of this, the base part of a messa 179 is in the drain region, and an insulated gate electrode 194 exists stretching over the whole vertical height of the drift region 184. And the device 170 becomes nonconductive in a first conditions, since a depletion is produced in the messa part of the drift region 184, by an appropriate relative voltage between the gate electrode 194 and the drift region 184. And in the second condition, it becomes conductive by the appropriate relative voltage between the gate electrode 194 and the drift region 184. And the impurity concentration of the drift region 184 of the device 170 is low.  Consequently, it becomes possible to make the device nonconductive even if the potential difference between the drift region 184 and the gate electrode 194 is zero, if material for the gate electrode is selected properly.
