Abstract

PURPOSE:To improve response and reliability and obtain easily many oscillation frequencies by switching and connecting plural sets of gate circuits, which set the gate voltage of the N gate thyristor constituting a relaxation oscilator circuit, by transistors. CONSTITUTION:Control signals are supplied from a room temperature regulator to transistor 15, and control signals are supplied from a fire detector to transistor 16, thereby switching and connecting gate circuits A, B and C. At an ignition time, transistors 15 and 16 are turned on, and a gate potential to obtain a frequency for transient strong burning it determined and is supplied to PUT21. When the control is transferred to normal strong burning, transistor 16 is turned off; and similarly, in transient weak burning, transistor 15 is turned off; and when burning is stabilized, transistors 15 and 16 are turned off, thus obtaining gate potentials to obtain respective frequencies.
