摘要： A workpiece is irradiated by a laser beam scanned in an oscillating track as the workpiece is advanced along a feed path in a hardening process. Sinusoidal variations in scan velocity are offset by decreasing the laser beam power level at phases in the scanning cycles corresponding to high and low scan displacement peaks, where the scan velocity is least. The beam power is increased near the scanning center line where the scan velocity is highest. The beam energy applied per unit of area is thus equalized over the scanning cycle. The workpiece temperature can be sampled at regular phases by a non-contact temperature sensor in the optical path, and used to control beam power versus phase in a subsequent scanning cycle. Alternatively or in addition, a sinusoidal beam power pattern can be stored and used to offset scan velocity variations as a function of phase.

摘要： A linear motor has a stationary member shaped as a channel and a moving member therein, with a magnet and an armature producing force for displacing the moving member along the channel. A first air flow path for cooling is defined along the path of the moving member in the channel. The moving member can have channels allowing cooling air to flow through. The channel can be closed over by a cover band passing through a slit in the moving member and closed or lifted by rollers on the moving member. The channel can be supplied with forced air flow by a blower and/or an exhaust fan, and preferably includes a filter for excluding metallic particles from the first air flow path.

摘要： Voltage fluctuating time integrating means integrates voltage fluctuating time when voltage of a sensor electrode fluctuates as a voltage fluctuation integrated time, and voltage fluctuation occurrence rate computing means computes a rate of occurrence of voltage fluctuation for time on the basis of the voltage fluctuation integrated time integrated. By doing so, quantity of generated plasma can be taken as the rate of occurrence of voltage fluctuation, and plasma detection judging means can easily detect large volume of generated plasma on the basis of the computed voltage fluctuation occurrence rate. Then, it is not necessary to provide a circuit for measuring electric resistance between the sensor electrode and a workpiece as a conventional way, thereby avoiding complexly structured plasma detector.
