Concerning the intelligent control of technique parameters in weaving preparation process known as automatic winder in textile production, the yarn tension, yarn defects, running speed and acceleration are key technique parameters which should be carefully monitored and controlled. The linear and rotating speed will definitely affect the dynamic tension of warp yarn during the winding process. The acceleration of the tension device on automatic winder and tension roller will affect the swing speed and amplitude, eventually influence the value and abirritation of dynamic tension. The capacitive transducer is used to detect yarn defects for improvement of yarn quality, in addition such sensor is qualified to monitor the acceleration of dynamic tension regulator. The principle and designation as well as application of relevant sensor has been discussed in this paper in detail.

Concerning the intelligent technique control of automatic winder in textile production, the tension of yarn in unwinding and winding process is a key factor among various technical parameters, the speed known as linear and rotational speed and the position of yarn layer on bobbin will definitely affect the dynamic tension of yarn during the winding process. the photoelectric encoder sonser is used for measurement of the rotationtional and linear speed of cyclinder of winder machine. Position sonser can detect the amount of the remaind yarn layer on bobbin so as to regulate the position of the tension controller to make the dynamic tension to be uniform and approporite.

Because characteristics of coal seams in the roadway are time-varying, and coal and rock distribution is very uneven. The boom-type roadheaders should be adjusted quickly on the basis of the conditions of the cantilever swing speed in real-time ,to overcome the change of the roadheaders cutting resistance and transition areas in the roadway. This paper presents a composite control mode of boom-type roadheaders based on neural network and genetic algorithm ,which can improve production efficiency highly, and safety and reliability.

A common requirement for both Atom Probe Field-Ion Microscopy (APFIM) and Scanning Tunnelling Microscopy (STM) is a sharp pointed tip for use as either the specimen (APFIM) or the probe (STM). Traditionally, tips have been prepared by either chemical or electropolishing techniques. Recently, ion-milling has been successfully employed in the production of APFIM tips [1]. Conventional electropolishing techniques are applicable to a wide variety of metals, but generally require careful manual adjustments during the polishing process and may also be time-consuming. In order to reduce the time and effort involved in the preparation process, a compact, self-contained polishing unit has been developed. This system is based upon the conventional two-stage electropolishing technique in which the specimen/tip blank is first locally thinned or “necked”, and subsequently electropolished until separation occurs.[2,3] The result of this process is the production of two APFIM or STM tips. A mechanized polishing unit that provides these functions while automatically maintaining alignment has been designed and developed.
