20120093448 | BELLOWS BEARING, AND BEARING ASSEMBLY STRUCTURE AND MINI ROTATING DEVICE USING THE SAME - A bellows bearing is a tube body formed by coaxially wrapping a wire. The tube body has a plurality of consecutively arranged bumps and recesses. End edges of the plurality of bumps form a contact portion, and the plurality of recesses forms an oil storage portion. Thus, when a mini rotating device using the bellows bearing rotates, a desirable lubricating, shock-resistant, and debris-removal effect can be achieved, thereby increasing the service life of the mini rotating device. | 04-19-2012 |
20120062063 | MOTOR MAGNETIC POLE ASSEMBLY AND MOTOR MANUFACTURING METHOD USING THE SAME - A motor magnetic pole assembly includes a coil body, an H shape base, and two conductive portions. The coil body has a central shaft in a center and connection ends at two ends respectively. The H shape base includes a column and a first plate body, the coil body surrounds the column, and the central shaft is parallel with the column. The two conductive portions are respectively arranged on a surface of the first plate body and are spaced by a distance, and the two connection ends are electrically connected to the two conductive portions respectively. Therefore, the motor magnetic pole assembly may be precisely and quickly placed on a circuit board through an automation process, thereby increasing a processing speed of a production line. | 03-15-2012 |
20110037368 | LAMP STRUCTURE - A lamp structure includes a lamp housing. A plurality of air intake holes is respectively opened on two opposite sides of the lamp housing, and a plurality of vent holes is opened between the plurality of air intake holes on the two sides. A heat sink and a light-emitting element disposed on the heat sink are disposed inside the lamp housing. The heat sink is surrounded by a plurality of heat dissipation fins to form an accommodation chamber for accommodating a fan. When activated, the fan intakes an airflow respectively through the plurality of air intake holes on two sides of the lamp housing, blows the airflow to the plurality of heat dissipation fins, and ventilates the hot air through the vent holes, thereby realizing a double circulatory heat convection exchange effect. | 02-17-2011 |
20100328881 | ELECTRONIC DEVICE - An electronic device is directly disposed on a lamp base and is powered by the lamp base. The electronic device includes a connection base matching with a specification of the lamp base, and an air-flow generator. The connection base may be directly screwed into the lamp base to power the air-flow generator, so that the air-flow generator operates to generate an air flow. | 12-30-2010 |
20100117471 | MICRO VIBRATION MOTOR WITH ADJUSTABLE VIBRATION AMOUNT - A micro vibration motor with adjustable vibration amount includes a rotor and a stator. The rotor includes a round cover; a perforation, formed on a rotation center of the round cover; a weight portion, integrally formed on an edge of the round cover, for changing a mass center of the round cover, in which the weight portion has at least one slot formed thereon; and at least one movable part, selectively disposed in each slot, for changing a weight of the weight portion, so as to adjust a vibration amount generated during the rotation of the round cover according to design demands. | 05-13-2010 |
20100074746 | FAN POSITIONING STRUCTURE - A fan positioning structure includes a base, a cover, and a fan. Through configuring a rotating shaft of the fan, one end of the fan presses against a stopping portion of the base, and the other end of the fan bears against a stopper of the cover, such that the fan is confined to stably rotating between the base and the cover. | 03-25-2010 |
