  • Patent number: 8203252
    Abstract: Permanent magnets are mounted within an electrical machine in a pitched saw-tooth pattern around the rotor shaft. This focused flux configuration provides for improved magnet mounting strength without resort to bonding or taping; provides improved rotor and stator cooling by access to the axial generator air flow; and provides for a simpler and more easily manufactured design. A laminated version of this basic structure provides for reduced surface losses and self-heating.

  • Patent number: 8196675
    Abstract: An impact hammer with pre-pressing damping and buffering effect includes a handle, outer barrel, air inlet, internal slide, actuating cylinder, air flow switching module and air inlet coupling portion. A front damper is assembled between the front end of the internal slide and the front end wall of the holding space and is characterized by a two-section pre-pressing rear damper assembled between the rear end of the internal slide and the rear end wall of the holding space. The two-section pre-pressing rear damper includes superposed upper and lower elastic buffers. At least the lower elastic buffer is pressed by a pre-pressing member to the preset degree. When the impact hammer yields recoil force under the impaction of the piston, the pre-pressing rear damper is employed to realize stronger buffering effect, so that the impact force is not much affected, thereby improving the impact efficiency and yielding excellent buffering effect.

  • Patent number: 8191917
    Abstract: The present invention provides a snowboard binding, including a mount, rear plate, top plate assembly base, rotary top pressboard, trigger support and coupling plate. The coupling plate, the mating frame of the rotary top pressboard, the mating ends of the trigger support and the top plate assembly base are coupled together to form a four-bar mechanism. The pressing state of the rotary top pressboard can be positioned directly by the perpendicular trigger support, and the rotary top pressboard can realize an expanded opening state over 90°. Thus, the snowboard boot can be slipped directly into the snowboard binding, enabling more convenient locating and release of the snowboard binding with better efficiency and applicability.

  • Patent number: 8186765
    Abstract: The present invention provides a method of manufacturing a toothbrush having needle-shaped bristles and a toothbrush manufactured using the method. The method of the present invention includes the step of grinding bristles, which have been set in a head part of a toothbrush, using a grinder provided with protrusions (11) having heights ranging from 1.5 mm to 7 mm. According to the manufacturing method of the present invention, a toothbrush having needle-shaped bristles can be manufactured without a separate chemical immersion process such that the thicknesses of the end points of the needle-shaped bristles range from 0.01 mm to 0.03 mm and the lengths of the tapered portions thereof range from 3 mm to 9 mm. Furthermore, because the process is simplified, the time required for production and the defective proportion is markedly reduced. As well, in the present invention, materials other than polyester can be used as the material for the bristles, unlike the conventional arts, in which this is impossible.

  • Patent number: 8181542
    Abstract: A pullout mechanism for a biosensor, wherein the pullout mechanism includes a permanent seat, a sliding seat, a resetter and a push type brake seat. The sliding seat is set into the sliding seat space of the permanent seat in a sliding state. A resetter is arranged between the permanent seat and the sliding seat, enabling resetting of the sliding seat. A push type brake seat is arranged laterally onto the casing. The push type brake seat includes a pushing portion and a driving end. The driving end can penetrate the threading portion of the permanent seat. When the pushing portion is pressed, said driving end can push the driven end of the sliding seat to control the state of the sliding seat, allowing for automatic pullout of the specimen in the specimen inserting portion, and improving the ease of operation with stronger applicability.

  • Patent number: 8181311
    Abstract: The present invention provides an adjustable hinged door closer, including a seat with the first and second cylinders, and a first and a second elastic linkage unit. A double-threaded regulator is incorporated onto the first connecting rod of the first elastic linkage unit, so as to change the compression of the spring and regulate the closing/restoring force of the door body. The double-threaded column of the double-threaded regulator has a double-thread that shifts to two thread pitches by just making one rotation, thus facilitating the fine-tuning easily. The elastic linkage unit and the regulator are structurally configured to be assembled externally, and then mated with the connecting seat of the door closer.
