PURPOSE: A nano power generation element and a method for manufacturing thereof are provided to independently and consistently operate by using piezoelectric characteristics of a hexagonal boron nitride atomic layer. CONSTITUTION: A hexagonal boron nitride atomic layer(120) is formed on a base substrate(110). The hexagonal boron nitride atomic layer has a single layer structure combined with a nitrogen atom and a boron atom in a hexagon. The hexagonal boron nitride atomic layer has piezoelectric characteristics to convert from the physical energy to the electrical energy. A first electrode(130) is formed on the hexagonal boron nitride atomic layer. A second electrode(140) is separately formed with the first electrode.

CONSTITUTION: A movable multipurpose lifting device comprises a horizontal frame(100), a lifting unit(200), vertical frames(300), an interval control guiding unit, wheels(500), and movement controllers(600). The lifting unit is movably coupled to the center of the horizontal frame and lifts a component. The vertical frames are coupled to both sides of the horizontal frame. The interval control guiding unit is installed on the top of the vertical frame and controls an interval between the vertical frames. The wheels are installed in both sides of the vertical frame. The movement controllers are installed between the wheels and move and fix the vertical frames.
Abstract:
A clamper for fiber insertion polymerization reinforcing steel is provided to prevent the damage to one part of the fiber insertion polymerization reinforcing steel extended by a tensile testing machine. A clamper for fiber insertion polymerization reinforcing steel comprises: a helical axis(50) screwed while its one side is inserted into one end of the fiber insertion polymerization reinforcing steel(1); and an axis of rotation(60) connected to the other end of the helical axis at the difference angle with the helical axis. The helical axis is formed integrally with the fiber insertion polymerization reinforcing steel. The fiber insertion polymerization reinforcing steel materially is clamped from the helical axis. The axis of rotation rotates the helical axis while rotating by the external force. The axis of rotation is manufactured separately from the helical axis. One part of the axis of rotation is enduringly fixed to the other side of the helical axis with welding. The axis of rotation is connected with the helical axis in to one body.
