Provided is a semiconductor device for high power application including a novel semiconductor material with high productivity. The actuator acts to rotate the output coupling, and in turn, the damper shaft to open the damper. The tube defines a proximal portion, a distal portion and a central pathway. The copper powder can be atomized copper powder, electrolytic copper powder, or a combination of atomized and electrolytic copper powder. Particular application to an oleic sunflower seed oil, an oleic rapeseed oil or to a mixture of monoalcohol esters of said oils, the process producing both an olefinic fraction and a monoalcohol or glycerol esters composition generally having more than half of its chains constituted by unsaturated C10 chains. The service tool has different operational configurations that can be selected and used without moving the service string.
