Abstract: A semiconductor device and a method of forming the same are provided. The method includes forming a bottom electrode layer over a substrate. A magnetic tunnel junction (MTJ) layers are formed over the bottom electrode layer. A top electrode layer is formed over the MTJ layers. The top electrode layer is patterned. After patterning the top electrode layer, one or more process cycles are performed on the MTJ layers and the bottom electrode layer. A patterned top electrode layer, patterned MTJ layers and a patterned bottom electrode layer form MTJ structures. Each of the one or more process cycles includes performing an etching process on the MTJ layers and the bottom electrode layer for a first duration and performing a magnetic treatment on the MTJ layers and the bottom electrode layer for a second duration.

Abstract: A power generating apparatus comprises a base, a rotary disk, a driving piece, a first energy gathering device and a pole. The rotary disk is pivotally connected to the base. The driving piece is connected to the rotary disk for controlling the rotary disk rotating. The first energy gathering device is disposed on the rotary disk. The pole is pivotally connected to the rotary disk, wherein a first heavy block is disposed at the end of the pole; an elastic piece is connected respectively to a front end of the pole and the first energy gathering device such that when the rotary disk rotates, the pole is kept vertically downwards and the elastic piece is stretched; while the pole moves with the rotary disk to a certain angle, the elastic piece is restored, so as to drive the first energy gathering device to gather energy.

Abstract: A portable drip structure comprises an inflating structure and a main bag. The inflating structure includes a motor and an air container and the motor and the air container are communicative with each other via a pipe provided there between, so that the air container can be inflated by the inflating structure. The main bag is provided with a first and a second compartment that neighbor with each other and each compartment is provided on the main bag with an opening that can be enclosed. The first compartment is for disposing a drip bag while the second compartment is for disposing the inflating structure. Consequently, when the two openings are enclosed and the air container is inflated via the motor, the air container will be expanded to press the drip bag in the first compartment to drip the infusion liquid in the drip bag outward.

Abstract: A power generating machine, including a frame with a stand thereon, two racks, two carriages, two branches and two spaced rods wherein horizontal tracks are at two sides of the frame bottom and the racks are at two sides of the stand and an inner post of the rack has a top guide wheel. The two carriages are connected movably at their inner sides with the two racks and have bottom tracks over the corresponding horizontal ones of the frame wherein an elastic member is disposed and moves within the bottom tracks. The two branches are linked at sides of the stand and connected with the carriages by a linking member, and two spaced rods are linked at sides of a crossbar so that when elastic member moves, the moment of force is changed, and the stand will sway if the linking member is pressed.

Abstract: An energy generating mechanism includes an energy generating device that has a solid frame with a lever received therein. Two cases are respectively and movably connected to two ends of the lever and each of the two cases has respective one of two boxes and each of the two boxes has an adjusting member which changes an arm of force of the lever so that the lever is controlled to swing up and down consistently. An energy collection device is connected to the energy generating device so as to collect energy generated by the energy generating device.

Abstract: A mechanical power generating device mainly has a stand disposed with a bull gear meshing with respectively a ratchet and a pinion on two sides thereof. The ratchet pivotally connects with a connecting link for connecting two u-shaped swing links; two ends of the swing link are respectively disposed with heavy blocks. The area adjacent to the center of the stand is respectively disposed with a sliding block and a rack; when the swing link swings, the heavy block presses the sliding block downwardly to relatively make the rack drive a driven gear to cause an electric generator to produce power. Furthermore, the swing link swings to rotate the bull gear for driving another swing link thereby achieving the objective of generating mechanical power.
