    • A lighting device may include a heat sink and a mounting surface provided a prescribed distance over the heat sink. A plurality of light emitting diodes may be provided on the mounting surface. The plurality of light emitting diodes may be positioned a prescribed distance from a point on the mounting surface. An enclosure having a prescribed shape may be provided over the mounting surface and the plurality of light emitting diodes. The enclosure may include luminescent material such that a wavelength of light emitted by the enclosure is different from a wavelength of light emitted by the plurality of light emitting diodes. A bulb may be provided over the heat sink to surround the enclosure.
    • 照明装置可以包括散热器和在散热器上设置规定距离的安装表面。 可以在安装表面上设置多个发光二极管。 多个发光二极管可以位于与安装表面上的点相距规定距离处。 可以在安装表面和多个发光二极管上设置具有规定形状的外壳。 外壳可以包括发光材料,使得由外壳发射的光的波长不同于由多个发光二极管发射的光的波长。 可以在散热器上方提供灯泡以围绕外壳。

    • A rotary toothbrush includes a handle member to be held by a user; a head member having bristles and connected to the handle member; a tilting member, provided on the head member, for tilting upwardly the head member at a predetermined angle; a rotating member, provided on the handle member and the head member, for rotating the head member with respect to the handle member so that the head member is arranged in a T-shape with respect to the handle member; and a driving member for driving the head member to rotate and tilt the head member. With the rotary toothbrush, a user can freely brush his or her teeth in an upward and downward direction or in a left and right direction, and bristles can come into contact with a lower portion of front teeth to prevent dental plaque from getting buildup as much as possible.
    • 一种旋转式牙刷,其包括由用户保持的手柄构件; 具有刷毛并连接到手柄构件的头部构件; 倾斜构件,设置在头部构件上,用于以预定角度向上倾斜头部构件; 旋转构件,其设置在所述把手构件和所述头构件上,用于使所述头构件相对于所述把手构件旋转,使得所述头构件相对于所述把手构件布置成T形; 以及用于驱动头部构件以使头部构件旋转和倾斜的驱动构件。 使用旋转式牙刷,使用者可以在向上和向下的方向或左右方向上自由地刷牙,并且刷毛可以与前牙的下部部分接触,以防止牙菌斑积聚得太多 尽可能。

    • A double-axis elongated polyester film for dyeing which simultaneously satisfies following formulas: 3.295≦NMD+NTD≦3.340  (1) Benzene plane orientation≦0.740  (2) Crystallinity (%)≦54  (3) 3≦Thermal shrinkage in machine direction(%)≦7  (4) 0≦Thermal shrinkage in transverse direction(%)≦3  (5) The polyester film is prepared by melt-extruding polyester chips and cooling the extrudate in a cooling drum to prepare a non-crystalline sheet; elongating said sheet at a temperature between 80 and 100° C. which is higher than glass transition temperature (Tg) to make 3.0 to 3.6 folds of length in machine direction to obtain single-axis elongated film; further elongating the film to 3.0-4.2 folds of length in transverse direction at 120-140° C.; thermally treating the obtained film in Tenter's thermal treatment zone at 210-240° C. with at least 5 stages; and rolling the double-axis elongated film obtained by releasing 0.01-10% of the film in machine and/or transverse direction. The film obtained above must satisfy both formulas (1) and (2).
    • 用于染色的双轴细长聚酯薄膜同时满足以下公式:聚酯薄膜通过熔融挤出聚酯切片并在挤出滚筒中冷却挤出物以制备非晶片; 在高于玻璃化转变温度(Tg)的80℃和100℃之间的温度下拉伸所述片材以使机器长度上的长度为3.0-3.6倍以获得单轴细长膜; 在120-140℃下,将膜长度进一步拉长至横向的3.0-4.2倍。 在Tenter的热处理区域中,在210-240℃下用至少5个阶段热处理得到的膜; 并轧制通过在机器和/或横向上释放0.01〜10%的膜而获得的双轴细长膜。 上述获得的膜必须满足式(1)和(2)。
