Title: Laser beam machining device
Inventor: SUDO KAZUYOSHI
IPC: B23K26/00
Filed: 1986-03-26
Abstract: PURPOSE:To maintain stable pulse laser light as set by calculating a correction value with respect to each pulse laser light based on an error obtained from a comparison means and controlling a laser power source means based on the correction value. CONSTITUTION:When the 1st laser output detected value is lower than a laser output set value, the 1st correction value is calculated based on its error. Then, when the 2nd pulse laser light is emitted, a corrected laser output set value adding the 1st correction value to the laser output set value is sent from a correction control part 112 to a laser power source 12 via an interface 40 together with other set values. The laser power source 12 supplies a pulse lamp electric current for excitation in accordance with those set conditions to a laser oscillator 10. Then, when the 2nd laser output detected value is still lower than the laser output set value, the 2nd correction value is calculated based on its error and when the 3rd pulse laser light is emitted, the corrected laser output set value adding the 2nd correction value to the laser output set value is given to the laser power source 12.

Title: Phase locked loop circuit
Inventor: ISHII SATOYUKI
IPC: H03L7/107
Filed: 1987-03-23
Abstract: PURPOSE:To reduce the converging time to a synchronizing state after the vertical synchronizing period by switching a time constant of a loop filter so as to quicken the acquisition speed of synchronism for a prescribed period after the phase locked loop is switched from the open state into the closed state and providing a means switching the acquisition speed of synchronism for the phase clocked loop adaptively. CONSTITUTION:A switch 17 is controlled by an output from a timing generating circuit 16 and a loop filter 19 is used for a prescribed period. The time constant of the loop filter 19 is set smaller than the time constant of the loop filter 18. Thus, the acquisition speed of synchronism is faster in using the loop filter 18. Thus, when a prescribed period elapses, the switch 17 is restored and the loop is switched into the state using the loop filter 18. Thus, the phase error caused in the vertical synchronizing period is decreased quickly and till a line superimposed with a character signal or the like comes, the state is converged into the phase lock state.
