.~> Temperature or current responsive means in circuit
DEFINITION
Classification: 331/175
(under the class definition) Subject matter wherein means are provided in the oscillator circuit to prevent or compensate for undesirable drift or change in oscillator frequency caused by changes in oscillator frequency such as by changes in (1) space discharge device characteristics, (2) circuit parameters, or (3) supply or bias voltages, or any combination of (1), (2) or (3).
(1) Note. This subclass does not provide for oscillators with automatic frequency stabilization wherein means are provided for sensing or detecting an undesired change in oscillator frequency, developing a control or error voltage proportional to such change and applying the control or error voltage to means for adjusting a frequency determining means of the oscillator in such a sense as to bring the oscillator back on frequency. For such subject matter search subclasses 1+ above.
