Abstract: An LED lamp (100) includes a frame (12), at least one LED module (20), a heat sink (32) and a cover (50). The LED module has a plurality of LEDs (220). The heat sink is mounted on the frame. The at least one LED module is attached to a bottom of the heat sink, whereby heat generated by the LEDs can be dissipated by the heat sink. A heat pipe (35) interconnects the heat sink and the cover. Thus, the heat generated by the LEDs can also be dissipated by the cover via the heat pipe. The cover is secured so as to shield a top portion of the heat sink and space from the top portion of the heat sink.

The side portion further includes a pair of projecting blocks (2111, 2112) laterally received in the retaining apertures for stable assembly.

Abstract: A vibration stator includes a housing (30), a stator (10) received in the housing and a rotor (20) being rotatably disposed in the stator. The stator includes two claw-pole assemblies (11) arranged back-to-back and located at two opposite ends of the vibration motor symmetrically. Each claw-pole assembly includes two yokes (10a, 10b) each having a plurality of pole teeth (16a, 16b) extending therefrom and being intermeshed with those of the other yoke. The rotor includes a permanent magnet (26) and an eccentric weight (24) connected with the permanent magnet.

Abstract: A vibration motor includes a housing, a stator (10) received in the housing (30) and a rotor (20) rotatably disposed in the stator. The stator includes two claw-pole assemblies (11) arranged back-to-back, and a shaft (23) being fixedly connected with the two claw-pole assemblies. The rotor includes a bearing (22) rotatably mounted around the shaft, a permanent magnet (26) mounted around the bearing, and an eccentric weight (24) fixedly attached to the permanent magnet. The eccentric weight includes a main body (240) and at least one inserting portion (244) having a density higher than that of the main body.

Abstract: A system, client and method for transmitting preview message in an instant messaging system are disclosed by the present invention.

Abstract: A cardan shaft structure with tightness adjustable functions has a through-hole passing through spheres located at both ends of the cardan shaft body, and a taper socket respectively installed into the opening end of each sphere. A bolt is inserted into both spheres and the body, fixed and locked together in conjunction with a nut. The cardan shaft structure works together with two clamping components wrapping around the spheres. When the sphere is being pushed against (or freed from) the inner wall of the clamping component by tightening (or loosing) the bolt so as to make the sphere either expand (or recover), the angle displacement of the clamping component becomes adjustable accordingly.
