摘要： An electric actuator includes a hollow actuator housing, an electric motor connected to the hollow actuator housing, a feed screw shaft coupled to the drive shaft of the electric motor, for transmitting rotational drive power from the electric motor, and a spline tube disposed in the hollow actuator housing in surrounding relationship to the feed screw shaft and held in engagement with the feed screw shaft, for displacement axially with respect to the hollow actuator housing with the rotational drive power transmitted by the feed screw shaft. Since the feed screw shaft is surrounded by the spline tube, dust and dirt particles are prevented from being deposited on the feed screw shaft.

摘要： A guide mechanism has a linear guide rail, a guide block displaceable along the linear guide rail, and a roller carrier plate interposed between the linear guide rail and the guide block and having an array of rollers held in line-to-line rolling contact with a side surface of the linear guide rail. The rollers roll in line-to-line rolling contact with the side surface of the linear guide rail, thus reducing resistance to the movement of the guide block along the guide rail and minimizing wear on the rollingly contacting components.

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.

摘要： To attract a workpiece with a limited contact region, e.g., a doughnut-shaped compact disc having a central circular hole, a skirt of a substantially arcuate attractor is held against an annular land extending around the central circular hole. Suction forces are applied through a plurality of suction holes surrounded by the skirt to attract the annular land for attracting and carrying the compact disc. A mini disc having an annular step along a peripheral region around a central hole thereof may stably be attracted and carried by an attractor having inner and outer annular contact members which axially project different distances to contact the peripheral region and an area, respectively, that is radially spaced from the peripheral region by the annular step.

摘要： Disclosed herein is a vacuum feeding apparatus for causing a working device such as a suction pad to communicate with a vacuum port so as to enable the working device to attract and hold a work or feed it to a desired position. In the vacuum feeding apparatus, components such as a valve section, a vacuum section, a filter section, a pressure detecting section, a manifold section, etc. are produced in blocks or units respectively. These blocks indicative of the above components can selectively be used in combination. In addition, a plate mounted on a corresponding block can be used to selectively make the changeover of any one of a plurality of fluid passages defined in the block and to cut off the selected passage.
