Title: Carrier reproducing circuit
Inventor: HORII AKIHIRO
IPC: H04L1/20
Filed: 1998-05-20
Abstract: A carrier reproducing circuit capable of reproducing a carrier quickly, wherein: a signal point arrangement convening circuit (14) detects the signal point arrangement of a demodulating baseband signal of a carrier when the carrier has a frequency different by a predetermined value from the center frequency of the modulated wave; a variance calculating circuit (15) calculates, based on the signal point arrangement, the number of times that the variance exceeds a preset threshold per unit time; a CN determination circuit (16) determines the reception CN ratio based on the number of times; a scanning step frequency width converting circuit (19) sets a frequency width changed by one step based on the determined reception CN ratio; the carrier for demodulation is sent out by changing oscillation frequencies of oscillators (6, 7) through an AFC circuit (20) based on the preset frequency width; and when a carrier synchronization judging circuit (18) detects that the number of times decreases to a value equal to or smaller than a threshold determined based on the reception CN ratio, the scanning by the AFC circuit (20) is stopped.

Title: Real time control of laser beam characteristics in a laser-equiped machine tool
Inventor: COLE III IRA E
IPC: B23K26/42
Filed: 2000-07-25
Abstract: A method and apparatus for real time control of laser beam characteristics in a high power laser-equipped machine tool. A beam path inp ut signal is produced related to changes in the length of the laser beam path a s the processing head of the machine tool moves over the workpiece. An integrator produces a signal related to the real time changes in thermal loading of the  laser output coupler as the laser beam is applied and as the output power level is adjusted. The beam path and thermal loading signals are used to drive a collimator so as to correct in real time for altered beam characteristics introduced by path length changes and thermal lensing of the output coupler. The result is to maintain control of the beam size at the focus optic. In addition, a further integrator produces a signal related to the real time changes in thermal loading of the focal optic as the laser beam is applied and as the input las er power level is adjusted. This correction signal is applied to the focus opti c adjustment mechanism to correct in real time for any shift in the focus opti c caused by thermal lensing of that optic.
