    • Light from a light source 10 is linearly polarized by a polarizer 11. Then it propagates via a half-mirror 12 almost parallel to the normal to a reflective liquid-crystal panel 13 and falls on the reflective liquid-crystal panel 13. The reflected light reflected by the reflective liquid-crystal panel 13 is received by a detector 15 via the half-mirror 12 and an analyzer 14. In this state, the reflective liquid-crystal panel 13 is rotated about an axis almost parallel to the normal to the reflective liquid-crystal panel 13 and an angle (extinction angle) at which the output signal of detector 15 reaches minimum is measured. Then, the gap of the reflective liquid-crystal panel 13 is detected based on the measured extinction angle. It is also possible to measure the output signals of detector 15 by arranging the analyzer 14 in a state in which the transmission axis thereof is almost parallel to the polarization direction of the incident light and a state in which it is almost perpendicular thereto and to detect the gap of the reflective liquid-crystal panel 13 based on the measured signals.
    • 来自光源10的光线被偏振片11线偏振,然后通过半反射镜12几乎平行于反射液晶板13的法线传播,并落在反射型液晶面板13上。反射光 由反射型液晶面板13反射的反射型液晶面板13由检测器15通过半透半反镜12和分析器14接收。在该状态下,反射型液晶面板13绕与反射型液晶面板13的法线大致平行的方向旋转 液晶面板13和检测器15的输出信号达到最小的角度(消光角)。 然后,基于测定的消光角检测反射型液晶面板13的间隙。 还可以通过将分析仪14布置在其透射轴几乎平行于入射光的偏振方向的状态和几乎与入射光的偏振方向相同的状态并检测检测器15的输出信号, 基于测量信号的反射液晶板13的间隙。

    • A linear motor elevation system comprising an elongated magnetic induction member (21) mounted along the hoistway. The induction member (21) has a plurality of magnetic poles (21a) disposed at equal intervals along the hoistway so that they face toward the armature (27). An elevator car (4) or a counter weight has attached thereto a field magnet (26) disposed in a facing relationship with respect to the magnetic induction member (21) for generating magnetic poles in the induction member (21). The field magnet (26) comprises an iron core (23) having a U-shaped cross section including a central web portion on which a field winding 24 is wound and parallel flange portions extending from the web portion toward the magnetic induction member (21). An armature (27) comprising armature windings (25) wound on teeth formed in the magnetic induction member (21) is also disposed on the car (4) in a facing relationship with resepct to the magnetic induction member (21) for generating a progressive magnetic field acting on the magnetic induction member (21) to generate an electromagnetic drive force for moving the car (4) along the hoistway. The magnetic induction element (31) may have a guide surface which is in guiding engagement with guide rollers (41) mounted on the car (4) for guiding it along the hoistway.
