Emphasises the effects of valve open and close speed control,valve stroke control,valve positioner control and setting of process parameter on the manufacturing process.

Cylinder Bore and Stroke Optimization Design Using Genetic Algorithm;

This paper mainly takes piercing die of protecting blank which is used in expressway as an example, and introduces how to adjust die structure to shorten effective work stroke of press, hence there is certain practical significance.

The gray run length and its statistical texture features of coal flotation froth image;

A method to code character image based on information of run length is presented, which can save a mass of file spaces with binary form to access data.

In this paper,we present a new approach to recognize line segments based on run length connection.

Study on Contact Temperature and Travel On-line Monitoring System of Circuit Breaker;

Several key signals including traveling and vibration of circuit breaker are processed based on wavelet transform which is used in embedded equipment.

This article is mainly about travel monitoring for high voltage circuit breaker using EPLD, which may simplify the circuit and enhance the flexibility and stability of the monitoring system.

PLC system is now widely used in many control systems In such systems limit switches are very common detecting elements But because limit switches have so many touch points and troubles always occur,which will influenc PLC system work In this article,the author pus forward some methods to improve the reliability of the

Based on that,a method of establishing a high precise interpolation table between the initial deflection(δ0) and straightening stroke(δ∑) is put forward for the determine of the straightening stroke of a automatic precise straightener,and a MATLAB program for the straighten-ing stroke's calculati.

Three calculation methods of straightening stroke are generalized and analyzed.
