A pressing apparatus is adapted for pressing a plurality of heat sinks on a circuit board, and includes a frame body and a plurality of pressing tools. The frame body includes a platform configured for placement of the circuit board thereon, and a mounting frame disposed above and spaced apart from the platform. The pressing tools are disposed at respective positions on the mounting frame. Each of the pressing tools includes an axle component, a universal joint unit disposed at a bottom end of the axle component, and a pressing head connected to the universal joint unit. The axle component extends downwardly between the platform and the mounting frame, and is configured to be resiliently and vertically movable. The pressing head is adapted for contacting one of the heat sinks, and is rotatable about the axle component by virtue of the universal joint unit.

A heat sink and an electronic apparatus using the same are disclosed. The heat sink comprises a fin structure and a fastening assembly; the fastening assembly comprises an adjustable positioning member, an elastic member, and a hooking member, the elastic member being disposed between the hooking member and the fin structure such that the adjustable positioning member combines the hooking member, the elastic member, and the fin structure; wherein the hooking member may secure the heat sink onto an electronic component, and the adjustable positioning member may be used to adjust the tightness between the heat sink and the electronic component.

Heat sink and electronic apparatus using the same

A method for designing an optimal bi-axial type of magnetic gear system that uses magnetic coupling for transmitting torque in order to be free from the defects caused by using a conventional mechanical gear system. A non-coaxial rather than a conventional coaxial type of magnetic gear design is considered for this invention. For the non-coaxial magnetic gear system, the size of torque will depend on the number of poles magnetized out of the strong magnetic material around the magnetic gear. Therefore, the optimum number of magnetized poles must be carefully selected for a set of specified conditions such that the largest torque can be obtained. An optimal magnetic gear system can be produced by the method in this invention.
