Title: Automatic frequency control circuit
Inventor: NAKAJIMA MASAHIRO
IPC: H03L7/08
Filed: 1982-02-04
Abstract: PURPOSE:To realize optional frequency discrimination characteristics easily, by dividing the output of a voltage-controlled oscillator into two, and putting them 90 deg. out of phase each other. CONSTITUTION:An input signal having an angular frequency difference DELTAomega from the oscillation frequency of the voltage-controlled oscillator 1 is phase-detected by phase detectors 3 and 4. The output of the voltage-controlled oscillator 1 is divided into two to obtain 90 deg. out-of-phase output signals 102 and 103. Those signals 102 and 103 are detected on binary basis by A/D converters 7 and 8 of a phase comparator 14 and their outputs 104 and 105 are compared and detected by a phase detector 9, which obtains a positive DC voltage when DELTAomega>0 or a negative DC voltage when DELTAomega<0. The signal 102, on the other hand, is differentiated by a differentiator 10 and squared by a squaring device 11 to obtain an output 108. This is passed through a low-pass filter 12 for AC component removal to obtain a DC voltage proportional to (DELTAomega)<2> and this is multiplied by the output 106 of the phase comparator 14 with a multiplier 13 to obtain a control signal having a frequency discrimination characteristic in an inverted S shape.

Abstract: PROBLEM TO BE SOLVED: To increase the uniformity of magnetic fields to make the image resolution better in measuring any cross-section by calculating the current values to be run into each channel of the magnetostatic correctors to impress them thereunto, based both on the distribution of magnetostatic fields obtained via the magnetostatic field distribution measuring instrument and the characteristics obtained via the characteristics measuring instrument. SOLUTION: The computer 318 controls the sequencer 307 to execute the pulse sequence to calculate the distribution of magnetostatic fields. Impressing a current into a specified channel of the system coil 318 obtains a distribution of magnetostatic fields. Then, repeating this operation by changing the channels into where a current is impressed at a time, obtains a distribution of magnetostatic fields for each channel when a current is impressed thereunto. The system characteristics required for correcting the magnetostatic fields are obtained from a difference between the distribution of magnetostatic fields, when a current is impressed into a specified channel and that in case of impressing no current into the system coil 318.
