Abstract: Provided is a polyarylene sulfide resin composition comprising (a) from 30 to 75% by mass of a polyarylene sulfide resin and (b) from 25 to 70% by mass of a filler, and containing (c) from 0.08 to 1.0 part by weight, relative to 100 parts by mass of the sum of (a) and (b), of an oxidized polyethylene wax having an acid value of at least 10 mg KOH/g and a dropping point of not higher than 120° C., or (d) from 0.1 to 1.0 part by weight relative to the same of a silicone oil having a viscosity at 25° C. of from 30 to 6,000 mm2/sec. The mold releasability of the moldings of the composition is improved, not interfering with the mechanical and chemical properties intrinsic to polyarylene sulfide resins.

Abstract: In a system for adjusting a laser oscillator, a laser beam from a laser oscillator is detected by a power detector 22 and one of the resonant mirrors is tiltably supported by a tilting mechanism. Power signal from the detector is sampled and sampled signals are averaged by a central processing unit to obtain power average values. The power average values are compared with a power distribution curve which relates to a tilting angle of the resonant mirrors. Thus, the central processing unit determines a control value corresponding to the tilting angle of the resonant mirrors.
