Abstract: A fan braking structure includes a fan including a frame having an upright bearing cup, and a fan impeller having a vertical rotating shaft pivotally received in the bearing cup and provided at a free end with a groove; a braking structure located at a lower part of the bearing cup and including a brake plate and an electromagnet, and the brake plate being provided at one side with a protruded brake pin and at another side with a magnetic member; and an elastic element disposed between and pressed against a top of the shell and the brake plate. When the fan is inactive, the electromagnet is energized to produce magnetic poles that repel the magnetic member and compress the elastic element, such that the brake pin is magnetically pushed toward the rotating shaft to engage with the groove, causing the fan to brake and stop rotating inertially.

Abstract: A fan brake structure includes a fan and a brake device. The fan has a frame body, a fan impeller and a stator. The brake device is disposed under a bottom of a bearing cup. The brake device has a driving member, a brake member and an elastic member. The elastic member abuts against one end of the brake member. The other end of the brake member has a boss body. The driving member has a spiral rail. When the driving member rotates, the boss body moves along the spiral rail, whereby the brake member linearly reciprocally moves upward to brake the fan impeller or linearly reciprocally moves downward to release the fan impeller from the braking.

Abstract: A fan anti-corrosion structure includes a base seat, a circuit board and at least one coating unit. The base seat has a sidewall and a bearing cup. A rest face extends from the sidewall toward the bearing cup. The circuit board is fitted around the bearing cup and disposed on the rest face. A closed space is defined between the circuit board and the base seat. The coating is coated on the circuit board. The circuit board is protected from the corrosion of the moisture and the salt fog by the coating unit and the closed space. Also, the cost of the mold for forming the coating unit is saved to lower the manufacturing cost.

Abstract: A fan bearing retaining structure includes a fan base seat having a bearing cup having a bearing hole. An inner circumferential wall of the bearing hole is formed with at least one restriction section and at least one recessed section. At least one elastic member and at least one retainer member are respectively positioned at the restriction section and the recessed section. A bearing is positioned between the elastic member and the retainer member. The elastic member serves to provide elastic force to tightly attach the bearing to the retainer member. Under such circumstance, the bearing is prevented from rotating or sliding within the bearing hole so as to avoid wear or failure of the bearing. Accordingly, the rotor assembly can smoothly operate.

Abstract: The present invention provides a rotor balance device and a method thereof. The device includes a balance measurement unit and at least one laser unit. The balance measurement unit has a correcting platen for supporting the rotor and at least one sensor. The laser unit receives a sensing signal outputted by the sensor to identify at least one position to be removed on the rotor and controls a laser beam to illuminate the position to be removed. By the inventive device and method, an improved degree of balance and reduced working hours can be obtained.

Abstract: Software bundles are installed on target computers by initially creating a set of distinct image files, each corresponding to a software bundle resident in a reference storage medium of a reference computer built according to specified hardware and software configurations. The image files are copied into each of a plurality of target storage mediums. The target computers are built according to the specified hardware configuration of one of the previously created image files and include the target storage mediums. Each target computer then selects one of the image files in its target storage medium, the selected image file corresponding to the hardware configuration of the target computer and having a desired software configuration. The selected image file for each target computer is decoded to produce the software bundle stored in the target storage medium.

Abstract: The present invention is a housing fastener for a blower, which comprises a base and a cover. The base is surrounded by a stop rail which comprises a plurality of fixing holes at proper places and a plurality of stoppers being convex at the edge of the stop rail. The cover is covered on the base, which comprises a plurality of buckling members extended out of the edge corresponding to the fixing holes; and concave parts near the buckling members corresponding to the stoppers. By the structure, the base and the cover are fastened to form a fan frame where the buckling members of the cover are firmly fixed to the fixing holes of the base to prevent from easy departure.

Abstract: The present invention is to provide a cable strain-relief member for a PC fan, comprising a pressing part, two locking parts at both ends of the pressing part, and two releasing parts at the two joint portions between the pressing part and the locking parts. Accordingly, the strain-relief member can be set at a rib of the fan frame to firmly bind lead wires on the rib of the fan frame to prevent from being swung left and right, or being shaken up and down, to be loosened by an external force. Besides, the strain-relief member can be released for easy maintenance and packing of the fan according to the actual need.

Abstract: In a method for installing software, distinct image files, each of which corresponds to a software bundle resident in a reference storage medium of a reference computer that was built according to a specified hardware and software configuration, stored in a master storage medium of a server that is coupled to the reference computers via a communications network are copied into copying storage media installed in copying computers. Each copying computer is configured to copy a selected image file in the copying storage medium that is installed therein into a corresponding target storage medium, which is coupled externally thereto via a connector unit. The selected image file corresponds to hardware configuration of a target computer and having a desired software configuration.

By the pivoted axis, two air guide plates are pivotally connected with the first pivoted joint, the second pivoted joint and the third pivoted joint. Therefore, the air guide plates are easy to be pivotally connected on the base portion and the base portion is easy to configure to the outlet of the fan.

Abstract: When installing software bundles on target computers, a set of distinct image files is first created, each of which corresponds to a software bundle resident in a reference storage medium of a reference computer that was built according to a specified hardware and software configuration. The image files are copied into each of a plurality of target storage mediums. The target computers are built according to the specified hardware configuration of one of the previously created image files, and have the target storage mediums installed therein. Each target computer is then enabled to select one of the image files in its target storage medium, the selected image file corresponding to the hardware configuration of the target computer and having a desired software configuration. Finally, for each target computer, the selected image file is decoded to result in the software bundle that is stored in the target storage medium.
