(1) Displacement sensors with resolution of 0.2, 0.5 and 1 nm were developed.(2) Very small ultraprecision positioning devices with resolution of 0.2, 0.5 and 1 nm were developed.(3) When the ultraprecision device is used for long time, the device deforms thermally by the heat from the motor. The vertical and horizontal thermal drifts on the device stage were measured. Four kinds of materials were used for the device stage, base and base support. As the result, the device made of stainless steel showed the largest thermal drift. The device made of low thermal expansion material didn't show smaller thermal drift than that we expected.(4) In order to eliminate the drift perfectly, a visual servo system was developed on the optical microscope. We could observe the observed object at the center of the visual field of the microscope.(5) Several kinds of the cormterplans to decrease the thermal drift of the ultraprecision device are shown as follows ; (1) To make the heat of the motor to flow to the base support. (2) To insert an adiabatic material between the motor and the base. (3) To cool the device by some kinds of methods.

(1)分别研制了分辨率为0.2、0.5和1 nm的位移传感器。(2)研制了分辨率分别为0.2、0.5和1 nm的超精密定位装置。(3)当超精密设备长时间使用时，设备受电机的热量而产生热变形。测量了装置台上的垂直和水平热漂移。装置舞台、底座和底座支撑采用了四种材料。结果表明，由不锈钢制成的器件表现出最大的热漂移。由低热膨胀材料制成的器件没有表现出比我们预期的更小的热漂移。(4)为了更好地消除漂移，在光学显微镜上设计了视觉伺服系统。我们可以在显微镜视野的中心观察被观察的物体。(5)几种减小超精密器件热漂移的方案如下；(1)使电机的热量流向底座支架。(2)在电机和底座之间插入绝热材料。(3)用各种方法冷却设备。
