Abstract: PURPOSE:To make possible the heating power adjustment of different kinds of gases by merely substituting the orifice by allowing a heating power control valve to slidably move through heating power control cams and adjusting a gas passage area which is formed by the heating power control valve and the orifice, corresponding to the turning angles of the operant. CONSTITUTION:When an operator 13 is rotated, a heating power control rod 11 is axially moved along the shape of a heating power control cam 27 set in accordance with a required arbitrary heating power control curve and a heating power control valve 9 energized by a spring F28 is moved up to only the same moving quantity as the above-mentioned. An orifice 10 having a slit of the above moving direction is mounted in a condition in which it is closely pushed against the heating power control valve 9 by a spring G29 and a gas passage length having the slit set in the orifice 10 by the movement of the heating power control valve 9 is allowed to change. In other words, the gas quantity corresponding to the heating power is almost proportional to the effective area of a gas passage and the effective area thereof is proportional to the length of a slit. The same heating power control characteristic can be obtained by exchanging only a part of the orifice even if a gas has different calorific power.

IPC: H03J7/18
Filed: 1979-11-27
Abstract: PURPOSE:To simplify the circuit and to make stable the operation, by detecting the presence of input carrier with the S-curve of output of the discriminating section. CONSTITUTION:If a sweep oscillator 6 is not locked, the output frequency of the oscillation section 6 is swept. If the output frequency of a high frequency amplifier section 1 is fc1 where fc1-fs1=+ or -fi, and if the output frequency of the section 6 is swept by regarding fs1 as a center, the S-curve in synchronizing to this sweep is appeared at the output of the discrimination section 4. The output of the discriminating section 4, if no signal is present in the amplifier section 1, is noise component and the frequency component is a very high frequency, while the S- curve is a sufficiently lower frequency, separation is made from noise surely by passing through a simple filter to detect the S-curve. Since the output level of the discriminating section 4 is at high level when the S-curve is a prescribed level, no amplifier section is required, allowing to drive the lick circuit 8 directly.
