    • Disclosed are an epicyclic gear system using two input characteristics and generating a gear shifting effect using two motor characteristics, a gear module including the epicyclic gear system, and a control method of the epicyclic gear system. According to one embodiment of the present invention, the epicyclic gear system comprises: a first gear part; a second gear part rotatably engaging with the first gear part; a third gear part rotatably engaging with at least one of the first and second gear parts; and a driving source for generating driving force, wherein two of the first to third gear parts function as input parts, each of which receives a driving force from the driving source, and the other gear part functions as an output part to output the combination of the driving force from the two gear parts. Accordingly, high speed/low torque or low speed/high torque can be selectively output according to the need via a combination of the two input characteristics, enabling a flexible change in the output characteristics even in a small robot.
    • 公开了一种使用两个输入特性并产生使用两个电机特性的换档效果的行星齿轮系统,包括行星齿轮系统的齿轮模块和行星齿轮系统的控制方法。 根据本发明的一个实施例,行星齿轮系统包括:第一齿轮部分; 与第一齿轮部可旋转地接合的第二齿轮部; 与所述第一和第二齿轮部分中的至少一个可旋转地接合的第三齿轮部分; 以及用于产生驱动力的驱动源,其中第一至第三齿轮部分中的两个用作输入部分,每个输入部分接收来自驱动源的驱动力,另一个齿轮部分用作输出部分,以输出组合 来自两个齿轮部件的驱动力。 因此,可以根据需要通过两个输入特性的组合来选择性地输出高速/低扭矩或低速/高扭矩,使得即使在小型机器人中也能够灵活地改变输出特性。

    • The invention relates to a film holder for periapical radiography for obtaining radiographs of intraoral teeth and of a teeth support structure, comprising: a bite unit to be temporarily fixed at teeth; and a film support unit rotatably mounted on the bite unit, and located at the tongue side of the teeth in the mouth, wherein the bite unit comprises a bite body to be bitten by the teeth so as to be fixed at the teeth; and a central shaft horizontally inserted into the side surface of the bite body, wherein the bite body comprises a first teeth contact surface contacted by an upper or lower tooth, and a second teeth contact surface contacted by the other one of the upper and lower tooth. The film support unit comprises: a shaft-receiving portion which accommodates the central shaft, and which is rotatably arranged; and a film support plate physically connected to the shaft-receiving portion so as to rotate around the bite body. The end of the film support plate, which is closer to the central shaft, is maintained at a position closer to the central shaft than at least one of the first and second teeth contact surfaces, thus structurally maintaining the end of the film support plate at the position closer to the central shaft without extension.
    • 本发明涉及一种用于获得口腔内牙齿和牙齿支撑结构的X光片的根尖片造影片夹,其包括:临时固定在牙齿上的咬合单元; 以及膜片支撑单元,可旋转地安装在咬合单元上,并且位于口腔中的牙齿的舌侧,其中咬合单元包括将被牙齿咬合以便固定在牙齿上的咬合主体; 以及中心轴,所述中心轴水平地插入所述咬体的所述侧表面中,其中所述咬体包括由上齿或下齿接触的第一齿接触表面和由所述上齿和下齿中的另一个接触的第二齿接触表面 。 膜支撑单元包括:容纳中心轴并且可旋转地布置的轴容纳部分; 以及物理连接到所述轴接收部分以围绕所述咬体旋转的膜支撑板。 更靠近中心轴的膜支撑板的端部保持在比第一和第二齿接触表面中的至少一个更接近中心轴的位置处,因此在结构上将膜支撑板的端部保持在 靠近中心轴的位置没有延伸。
