Filed: 2002-06-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an output controller of an inverter in which control is stable even if a reactor is minimum and both downsizing of an apparatus and stabilizing in control are realized.  <P>SOLUTION: A subtracter 8 provides a difference between a current command I' corresponding to a wanted electric power supplied to a discharge tube 3 and an output current I of an inverter 1. An error amplifier 10 amplifies the difference and outputs it to an adder 9. A signal generator 21 generates a simulation signal (for example a sine wave signal) comprising such waveform as simulates the waveform of a load voltage V2. The adder 9 adds the output of the error amplifier 10 to the output of the signal generator 21, and outputs as an output voltage command V1' of an output voltage V1 of the inverter 1. An on/off controller 11 generates the pulse train of square waves equivalent to the output voltage command V1' based on the output voltage command V1' and the generated square wave pulse train is supplied to a switching element constituting the inverter 1.  <P>COPYRIGHT: (C)2004,JPO

Notches 56 are formed in the heat insulating plate 55 in the circumferential direction, and the notches 56 are shifted in the peripheral direction so that they do not overlap with each other. Since a wafer group in a lower end region can be detached from a furnace port by a heat insulating plate group, the temperature of a whole boat length can be made uniform. Then, the maintenability of the contaminated heat insulating plate can be improved since the heat insulating plate can be pulled out in a horizontal direction. Then, temperature uniformity in wafer face can be maintained since heat radiation from the notches can be prevented by shifting peripheral positions of the notches.  <P>COPYRIGHT: (C)2004,JPO
