A plasma enhanced atomic layer deposition (PEALD) system is described, wherein the system comprises a processing space and a high vacuum, ultra-clean transfer space. During processing, the substrate to which the thin conformal film is formed is exposed to the processing space. During substrate transfer, the substrate is exposed to the high vacuum space. Processing gases are introduced sequentially and alternately to the process chamber and the pressures and gas flows within, to and from, and between the process chamber and the high vacuum transfer space are controlled to keep the transfer space ultra-clean.

A capper head for general purpose usable even when the specifications of a cap including thread pitches are changed without using a fixed gear and a lifting cam determining a lifting stroke and the timing thereof. The rotational output of a servo motor (2) is transmitted to a screw mechanism (4) through a sliding engagement section (3), and a screw shaft (17) is lowered while rotating for capping. The lowering stroke of the screw shaft (17) is allowed by the sliding engagement section (3). In capping, even if the strokes of a rotating chuck (7) and an output shaft (31) are different from the lowering stroke by the screw mechanism (4), a stroke difference absorption section (5) absorbs the stroke difference therebetween since a spring (23) in combination with a spline transmitting the rotation is deflected in the axial direction.

The invention relates to a movable concrete mixing pump truck integrating concrete production with pumping into a whole, comprising an automobile cassis, wherein an electric control chamber, a power supplying device, a concrete mixing and pumping device, a powder storing device, a powder conveying device, a powder weighting device, an aggregate continuous loading device, an aggregate weighting device, an aggregate conveying device, a clear water storing device and a clear water weighting device are arranged on the automobile chassis; the powder conveying device is connected with the powder storing device and the powder weighting device; the powder weighting device is connected with an inlet of a mixing main machine; the aggregate continuous loading device is connected with the aggregate weighting device; and the aggregate weighting device is connected with the inlet of the mixing main machine through the aggregate conveying device. According to the arm support type concrete mixing pump truck, the functions of continuous loading, raw material storing, weighting, concrete mixing, conveying, concrete pumping, and the like on the concrete as the raw material are integrated on freely-movable equipment; and the arm support type concrete mixing pump truck has a simple structure and is practical.
