摘要： Disclosed herein is a mechanism for locking the angular movement of a suction pad. The mechanism comprises a tubular body fitted to a root part of the suction pad and having a flange; a cover member attached to a moving assembly for displacing the suction pad; a first bush having a slide resistance lower than the tubular body and fitted to the flange of the tubular body; and a second bush having a slide resistance lower than the cover member and fitted to the inside of the cover member. The first bush and second bush are engaged with each other in such a manner that alternating concavities and convexities of the first bush are meshed with alternating convexities and concavities of the second bush, respectively, whereby the displacement of the suction pad in its axial direction is guided, and the angular movement of the suction pad is prevented.

摘要： An electric actuator has a body with a hole defined therein and an electric motor fixed to an end of the body. The electric motor has a rotatable shaft to which a feed screw is coaxially connected, and a feed nut is threaded over the feed screw. The hole receives an elongate cylindrical tubular member slidably fitted therein which surrounds the feed screw. The feed nut is secured to an end of the tubular member, and a support for feeding a workpiece supported thereon is fixed to the other end of the tubular member. The feed screw, which serves as a drive force transmitting shaft, is protected by the surrounding tubular member from the deposition thereon of dust, dirt, or other foreign matter and hence from unwanted shutdown or breakage.

摘要： Helical gears are used for a sun gear, planet gears, and an internal gear. Accordingly, when a load, which exceeds a preset torque, is applied to the internal gear, the internal gear is moved in a direction toward an input shaft or a direction toward an output shaft while making rotation in a direction different from that of the sun gear to automatically switch the speed reducing ratio.

摘要： Pressed shape steel, made of a low cost general steel material that is not hardened, forms a frame with long grooves cut therein. Guide rails, made of a specialized steel material that can be subjected to a hardening treatment, are hardened. Thereafter, outer surfaces of the hardened guide rails are ground and the guide rails are integrally joined in the long grooves. Ball-rolling grooves are formed in the guide rails, thereby completing a guide-equipped frame for an actuator. Because the general steel material and the specialized steel material are principally ferrous materials, both exhibiting a Young's modulus at or above 170 GPa with substantially the same coefficient of linear thermal expansion, the frame needn't be increased in size or have a complex internal structure to reinforce the strength of the frame, and the guide rails remain securely retained in the grooves even if the actuator experiences changes in temperature.
摘要翻译：由未硬化的低成本普通钢材制成的压制型钢形成在其中切割有长槽的框架。由能够进行硬化处理的专用钢材制成的导轨被硬化。此后，硬化的导轨的外表面被研磨，导轨一体地接合在长槽中。在导轨上形成滚珠槽，从而完成用于致动器的引导装置的框架。由于普通钢材和专用钢材料主要是铁质材料，两者都具有170GPa以上的杨氏模量，且线性热膨胀系数基本相同，所以该框架不需要增加尺寸或具有复杂的内部结构以加强框架的强度，并且导轨仍然牢固地保持在凹槽中，即使致动器经历温度变化。

摘要： A method of and a system for electrically processing vacuum pressure information, which is suitable for use in a vacuum unit. Pressure values are detected and a desired pressure value lower than the highest vacuum pressure value of the detected pressure values is displayed on a displaying device in digital form. The desired pressure value is stored in a storing device. Each of pressure values relative to vacuum, which are detected by a pressure detecting element held in front of a passage communicating with a vacuum port, is converted into a digital signal. The so-converted digital signal is digitally displayed on the displaying device. The desired pressure value stored in the storing device is compared with each of the detected pressure values relative to the vacuum, and information about faulty points is displayed on the displaying device based on the result of comparison.
