Abstract:
A fastening device for mounting on a tube includes: a tubular sleeve member adapted to be sleeved around the tube, defining a reception space to snugly receiving the tube and a notch for access into the reception space and having an inner wall surface defining the reception space and formed with a press element; and a fixing element mounted on the sleeve member at the notch such that tightening of the fixing element relative to the sleeve member results in pressing of the press element against the tube to deform the tube to possess an outwardly minor protrusion for abutting against the fixing element, which creates an inwardly dented minor recess on its outer wall surface of the tube.
Abstract:
A light cover capable of adjusting the amount of light emitted is provided in the present invention. The light cover includes a cloth, a supporting frame and a binding member. The supporting frame includes three/four intersecting elastic supporting rods. A light emitting opening and a triangular/square mounting portion are formed by assembling the cloth with the three/four intersecting elastic supporting rods. The binding member is assembled with both ends of each of the three/four elastic supporting rods. By tightening the binding member around the ends of the three/four elastic supporting rods, the three/four intersecting elastic supporting rods are bent into different curvatures, thereby adjusting the size of the light emitting opening.

A method of forming a semiconductor device is provided. A first interfacial material layer is formed by a deposition process on a substrate. A dummy gate material layer is formed on the first interfacial material layer. The dummy gate material layer and the first interfacial material layer are patterned to form a stacked structure.

The stacked structure is removed to form a trench in the ILD layer. A second interfacial layer and a first high-k layer are conformally formed at least on a surface of the trench. A composite metal layer is formed to at least fill up the trench.
