Abstract: A ceiling fan includes at least one rotary shaft that has a seat being semi-circular and a guiding portion being semi-spherical and having a guiding surface. A lower sealing ring of the ceiling fan has at least one protrusion. The guiding portion is mounted through the lower sealing ring and the guiding surface abuts against the at least one protrusion. With the seat of the rotary shaft being semi-circular and the guiding portion being semi-spherical, when the rotary shaft is rotated, the guiding surface and the at least one protrusion coordinate with each other to rotate. The rotary shaft has reduced volume. Accordingly, the ceiling fan having the rotary shaft is lightweight, has reduced power consumption and manufacturing cost, and is easy for installation.

Abstract: An educational gaming device for learning evolutionism comprises a display device, a storage device and an operation unit. The storage device stores at least one scene and a plurality of corresponding representative creatures. The storage device and the display device are coupled to the operation unit. The operation unit selects at least two creatures from the representative creatures to respectively function as at least one player character and at least one non-player character. The operation unit drives the display device to show the process of interactivity and evolution of the player character and the non-player character in the scene. The game of the present invention features clear rules, instant feedbacks and competitions, and has much more interaction with the users than common instructional activities or common educational animations.

Abstract: A heat dissipating device includes a heat receiver, a fin member arranged on the heat receiver and including a plurality of spaced fins, a plurality of heat pipes connecting the heat receiver with the fin member, and a fan located at one side of the fin member for producing airflow to the fin member. One half-bowl-shaped guiding structure is formed at each of the fins for guiding the airflow produced by the fan to blow to portions of the fin member adjacent the heat pipe.

Abstract: A locking device (10) for securing a heat sink (20) to a heat generating component (30) includes a pair of operating members (14) and a pair of locking members (16). Each operating member includes a pivot shaft (142) defining an axis and an operation handle (144) extending from the pivot shaft along a first direction. The pivot shaft has an offset section (146) offsetting from the axis thereof in a second direction. The first direction and the second direction form an angle therebetween. Each locking member is attached to the offset section of one of the operating members. The operation handle of each operating member is capable of rotating about the axis of the pivot shaft from an unlocked position to a locked position and accordingly the offset section of the pivot shaft drives the locking member to move upwardly.

Abstract: A heat dissipation device for dissipating heat from an electronic package comprises a heat sink, a fan, a fan mounting structure, and fixing devices. The heat sink comprises a main body which comprises a cutout on each corner. The fan mounting structure mounts on two opposite sides of the heat sink and the fixing devices fix the fan on the fan mounting structure wherein the fixing devices extend through the mounting structure into the cutouts and do not damage the heat sink. The fan mounting structure has two lower plates fitted into two grooves in two opposite sides of the heat sink. Each lower plate extends along a whole length of each of the grooves.

Abstract: A retaining device (20) for mounting a heat sink (30) to an electronic device (40) includes an unitary metal wire clip (22), a locking device (26) and a camming member (24). The clip includes a pair of spaced apart pressing beams (221), at least one latching beam (223) and a crossbeam (225). The latching beam is set at one side of the pressing beams. The crossbeam extends between the pressing beams at an opposite side thereof. The camming member is pivotably attached to the locking device and includes a cam (242) being engageable with the crossbeam. The camming member is pivotable relative to the locking device from an unlocked position to a locked position and the pressing beams force the heat sink into close contact with the electronic device when the camming member is located at the locked position.

Abstract: A fan holder, for attaching a fan to a heat sink, includes a base, fasteners, and clamping arms. The fasteners extend from the base. Each of the fasteners defines an arc-shaped locking portion engaging with the fan. The clamping arms extend from the base opposite to the fasteners, and engage with the heat sink to thereby attach the fan to the heat sink.
