|20130039757||HEAT DISSIPATING FAN HAVING A POROUS SINTERED BUSHING FOR AN IMPELLER SHAFT AND METHOD OF MAKING THE BUSHING - A method of making a porous bushing for an impeller shaft of a heat dissipation fan, includes: compacting a porous body-forming material in a mold to form a green body that has a shape conforming to the porous bushing; and sintering the green body to form the porous bushing. A heat dissipating fan incorporating the porous bushing is also disclosed.||02-14-2013|
|20130038264||METHOD OF FAN SPEED CONTROL - In a method of fan speed control, a flow value corresponding to airflow amount through a fan during operation of the fan is detected with a fan controller. The flow value and a preset value are subsequently compared, and when the flow value is less than the preset value, a pulse-width-modulation (PWM) signal is outputted to increase rotation speed of the fan.||02-14-2013|
|20120119608||MOTOR STATOR - A motor stator includes a stator unit and at least one auxiliary unit. The stator unit includes a circuit substrate, and a plurality of spaced-apart induction coils embedded within the circuit substrate. The auxiliary unit includes an auxiliary coil attached to and disposed outwardly of the circuit substrate.||05-17-2012|
|20120119607||MOTOR STATOR - A motor stator includes an insulating frame having a plurality of projecting rods, an induction unit, and a plurality of conductive members. The induction unit includes an induction circuit board, a plurality of induction coils embedded within the induction circuit board, and a plurality of coil windings wound respectively on the projecting rods. The conductive members extend through the insulating frame and the induction circuit board for establishing an electrical connection between each of the induction coils and a corresponding one of the coil windings. The turn numbers of the coil windings are not limited by the area and thickness of the induction circuit board, and can be increased. Alternatively, the coil windings may be positioned to increase the magnetic pole slot number when energized. As such, a driving force of the motor stator can be increased.||05-17-2012|
|20120119606||MOTOR STATOR AND ASSEMBLING METHOD THEREOF - A motor stator includes a stator unit and an auxiliary induction unit. The stator unit includes a circuit substrate, and a plurality of induction coils embedded within the circuit substrate. The auxiliary induction unit includes an insulating member, a magnetic conductor, and at least one coil winding assembly. The coil winding assembly includes a conductive rod and an auxiliary coil. The rod has an insert rod section extending through the magnetic conductor, the insulating member, and the circuit substrate, and a wound rod section permitting the auxiliary coil to be wound thereon, such that the auxiliary coil is disposed outwardly of the magnetic conductor. During assembly, the induction coil assembly is mounted to the magnetic conductor, and the insulating member is superposed on the circuit substrate. Subsequently, the rod is inserted through the insulating member and into the circuit substrate.||05-17-2012|
|20110026863||ROTARY SHAFT ASSEMBLY - A rotary shaft assembly includes: a rotary shaft having an insertion end portion that is disposed co-axially in a hollow base, and rotatable relative to the base; a bearing sleeved on the insertion end portion of the rotary shaft, and partitioning an inner receiving space in the base into a lower oil-storage portion and an upper oil-flow portion; and a stirring member mounted on one end of the insertion end portion and co-rotatable with the rotary shaft. When the rotary shaft rotates, the stirring member stirs lubricating oil in the lower oil-storage portion to urge flow of the lubricating oil from the lower oil-storage portion through a first oil passage unit in one of the base and the bearing, through the upper oil-flow portion and through a second oil passage unit between the bearing and the insertion end portion of the rotary shaft, and back into the lower oil-storage portion.||02-03-2011|
