    • Disclosed are a method and a device for detecting the phase of a moving object using a heterodyne interferometer. A heterogeneous mode helium-neon laser is used in the heterodyne interferometer as a direct light source to increase a measuring speed and a measuring resolution performance as well as minimizing the loss of the light source. Signals, which have only a frequency difference between reference signals or measured signals and arbitrary signals, are extracted from signals which are obtained by multiplying the arbitrary frequency signals by the reference signals or the measured signals. After frequencies of the reference signals and the measured signals are converted, a phase difference of the extracted signals is measured, and a displacement of the moving object is measured. The laser interferometer system of the present invention includes a laser light source part, an optical interferometer, a frequency converter, and a phase measurer. The light source used in the heterodyne interferometer uses output light emitted from a heterogeneous mode helium-neon laser generator, which is stabilized in frequency, and such output light have two frequencies which are at right angles to each other and linearly polarized.
    • 公开了一种使用外差干涉仪来检测移动物体的相位的方法和装置。 异质模式氦氖激光器在外差干涉仪中用作直接光源,以增加测量速度和测量分辨率性能以及最小化光源的损耗。 从参考信号或测量信号和任意信号之间仅具有频率差的信号从通过将任意频率信号乘以参考信号或测量信号而获得的信号中提取。 在参考信号和测量信号的频率被转换之后,测量提取的信号的相位差,并测量移动物体的位移。 本发明的激光干涉仪系统包括激光光源部分,光干涉仪,变频器和相位测量器。 外差干涉仪中使用的光源使用从异相模式氦氖激光发生器发射的输出光,其频率稳定,并且这种输出光具有彼此成直角和线偏振的两个频率。

    • The present invention relates to a construction hoist in which carriers for lower and upper sections are installed in one vertical frame in order to improve performance of the carriers, thereby improving work efficiency. This objective of the present invention is accomplished by the constitution which includes the one vertical frame, the lower and upper carriers, and a shock absorbing unit. The vertical frame is installed separate from the exterior wall of a building by connecting trusses, each of which is a single unit with a rack gear on one side thereof. The carriers include pinion gears which operate by engaging with the rack gears in correspondence with drive motors which are installed on top of the carriers to execute ascent and descent driving with applied power. Therefore, the carriers can ascend and descend within the respective upper and lower sections about one point of the vertical frame. In addition, each carrier is equipped with a front door and embedded with a controller including control buttons. The shock absorbing unit is installed on one site of the vertical frame to dampen impact by the upper carrier in the event of an uncontrolled fall of the upper carrier along the vertical frame.
    • 本发明涉及一种施工升降机,其中下部和上部的载体安装在一个垂直框架中,以便提高载体的性能,从而提高工作效率。 本发明的目的是通过包括一个垂直框架,下部和上部托架以及一个减震单元的结构来实现的。 垂直框架通过连接桁架与建筑物的外墙分开安装,桁架的一侧是单个单元,带有一个齿条。 载体包括小齿轮,其通过与安装在载体顶部的驱动马达对准齿条啮合,通过施加的动力进行上升和下降驱动。 因此,载体可以在相应的上部和下部中在垂直框架的一个点附近上升和下降。 另外,每个行李架都配有一个前门,内置一个包括控制按钮的控制器。 冲击吸收单元安装在垂直框架的一个位置上,以在上部托架沿垂直框架不受控制地坠落的情况下,抑制上部托架的冲击。
