摘要： A fractional-N frequency synthesizer is offered which does not produce spurious signals of periodically conspicuous spectral intensities and can cancel produced spurious signals up to a practical level even with a spurious-canceling circuit of low accuracy. The synthesizer has a sigma-delta noise shaper. The integral and fractional parts of a frequency divide ratio-setting value that frequency-divides the output signal are set. The fractional part of the frequency divide ratio-setting value is applied to the sigma-delta noise shaper every phase comparison period. The output from the noise shaper and the integral part of the frequency divide ratio-setting value are summed up to thereby produce a sum. The output signal is frequency-divided, using this sum as a frequency divide ratio. The difference between the fractional part of the frequency divide ratio-setting value and the output from the sigma-delta noise shaper is produced and accumulated in an accumulator every phase comparison period. The spurious-canceling value is produced based on the value of the accumulator.

摘要： A laser processing device for collecting a laser beam from laser beam radiating means using an objective lens and irradiating a surface of a sample with the collected laser beam to form a fine pattern thereon is disclosed. The device comprises a uniform pellicle film having high transmittance to wavelength of the laser beam and provided between the objective lens and the surface of the sample. The laser beam radiated from the laser beam radiating means passes through a shutter and a beam expander, and is reflected by a dichroic mirror. The laser beam is then collected by the objective lens and passes through the pellicle film to be radiated on the surface of the sample. Thus, laser processing may be carried out without deteriorating performance of the objective lens.

摘要： A system for compensating image contour by modulating a scanning velocity in accordance with a video signal is disclosed, in which a mean current dissipated in a driving power amplifier is detected to control a gain of an amplifier in a preceding stage for suppressing the increase of power dissipation in the power amplifier when a video signal having many noises is received. The preceding stage amplifier is provided with a saturation characteristic to enhance the effect of contour compensation at a small amplitude signal and eliminate over compensation of image contour at a large amplitude signal. The combination of the saturation characteristic and the gain control further enhances the effect of suppression of power dissipation.
