The current jacking system for the hydraulic electric furnace electrode in Jilin Ferroalloy Factory is adopted the hand control in electrode jacking plan  against this situation  a structure  which can adapt the linear stepping motor to control the digital valve for adjusting the location of the hydraulic system has been raised  and the current system would realize automatic control to the electrode jacking by this way  at the same time  and by Fuzzy-PID control method the linear stepping motor would be controlled to obtain precise positioning in control. The hydraulic system controlled by digital valve have been described and analyzed in jacking feasibility and stability. What's more  it is inspected and verified that the adjustment of this system has high precision and quick response. 2009 IEEE.

The valve-less piezoelectric pump is more suitable for minimization and microminiaturization than the valve piezoelectric pump  especially for the Microelectromechanical System (MEMS) because of its simple structure. However  in order to control the flow direction of the fluid through the pump  some assembles have to be attached outside the chamber. And it is no doubt that these assembles will take some space and hinder its further microminiaturization. In this paper  a novel valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (UCCB) is presented. It ingeniously takes advantage of the space of the chamber by developing its bottom into a unsymmetrical corrugation shape along the axis of the inlet and outlet. As a result  a series of diffuse pipes and nozzle pipes (or wedge-shaped pipes)  which substitute the regular diffuse/nozzle elements fitted outside the chamber  are alternatively formed between the unsymmetrical corrugation chamber bottom (UCCB) and the piezoelectric vibrator. The piezoelectric vibrator is opposite to the UCCB. And these diffuse pipes and nozzle pipes are able to force the fluid in the chamber to flow along a single direction when the pump works. And then the mathematic model is established to present the relationship between the mean energy loss and the flow rate of the pump. Basing on the mathematic model  the theory on the pump working is analysed. Finally  a real UCCB valve-less piezoelectric pump is manufactured  and the test with it is carried out to verify the theory above-mentioned. 2006 IEEE.

Photolithography shutter is usually used to control exposure in order to obtain patterns of code disc and metrology grating which are the core components of optical shaft encoder. But perforated film as photolithography shutter has many disadvantages such as taking too long time to perforate  easily making wrong code  lower reusable ratio. Mathematical models for resist property  luminous efficiency and exposure have been established by deducing their relations for avoiding the disadvantages  which provides the theory of using liquid crystal light valve (LCLV) replacing proforated film. Based on operating principles of LCLV and control theories of photolithography shutter  the principle diagram of control circuit of LCLV arrays has been designed according to theirs control principles. In the control system  LCLV arrays as photolithography shutter are realized by adopting DS75451 to drive them and using AT89C51 chip to control them. By photolithographic experiment  the patterns of code disc are good  the edges of lines are vertical  it indicates LCLV arrays as photolithography shutter may control exposure and light passing accords with the intending requires. It proves using LCLV arrays replacing perforated film as photolithography shutter is feasible completely.
