Abstract: A trench-gate transistor device includes a substrate and a transistor structure. The transistor structure includes a plurality of superjunctions arranged in a first direction, a rectifying area that has at least one Schottky-based diode, and at least one active unit that is located at a side of said rectifying area in a second direction that intersects with the first direction.

Abstract: A vertical wind-driven generator blade comprising: a bracket with a generator unit therein, the upper end of the bracket is provided with a blade set, the blade set includes a connecting shaft, two connecting pieces at least and at least two blades, and the lower end of the connecting shaft of the lowermost blade set is connected to the generator unit, and the connecting shaft is axially provided with two connecting pieces at least around the upper end of the bracket, which is radial and formed into a concave arc shape at the same direction; each blade is extended to a unit large blade or more at the length and height direction, and assembled into the vertical wind-driven generator with two large blades at least. With this structure, the present invention can effectively improve the generated power and the operation convenience.
