Abstract: By analyzing the communication principles of ControlNet and combining with the specific production process flow, the ControlNet control system has been designed. Meanwhile, the ControlNet network optimization scheme is proposed and has been applied in the actual production according to the existing ControlNet design problems. The application result shows that the network division and network key parameters setting are very effective optimization methods, which successfully solved the emerging ControlNet fault in the production process and met the control requirements. At the same time, they are worth to be consulted for ControlNet design and optimization.

Abstract: In order to meet the demand of precise measurement and applications, based on the total-reflection phase transformation theory of the phase retardation, the principle of phase retardation with oblique incident angle is expounded. Spectral characterization of the phase retardation varing with refractive index is analyzed to high precision achromatic phase retarder to oblique incidence aided design. The result indicates that there is a maximum to dispersion curve of achromatic phase retarder with oblique incident in the center of the design refractive index department. The phase-delay drops on both sides to the center of the refractive index and can pass through a definite retardance value twice at two specified wavelength values. Accordingly, based on the detailed design of Fresnel rhomb, The new achromatic retarder with the specific incident angle and high precision is designed by choosing suitable meterial .It is shown at the achromatic property curve within the range of 500 nm to 1150 nm theoretically that the maximum deviation of the retardance from 90° is 0.006°, whereas at λR1R=532 nm and λR2R=1064 nm the retardance is approximately 90°±0.001°. and the corresponding calculation to the size of the devices indicates that the size of the devices for the same aperture will decrease for higher refractive index values.So optical materials with higher refractive indices are more convenient for this type of oblique incidence retarder .

Abstract: Microelectromechanical processes were used to generate a stamp with array of micro pillars. This stamp was subjected to DNA combing and imprinting to form nanostrands between the micro pillars, followed by sputter coating with gold, vapour deposition and imprinting processes in order to produce the required nanochannels for the gene chip. These preparation processes have been widely used to create implementations for cell manipulation and electroporation. However, the underlying mechanism of DNA stretching has only been demonstrated experimentally and is not fully understood. It, therefore, arrives unstable yield rate when process parameters are changed. This study investigated the DNA combing and imprinting processes using two-phase flow and moving mesh methods to analyse the variation of flow field at the micron level. It shows that while withdrawing from water, a smaller velocity difference in each location and the velocity difference of pillars are the major determinants of DNA stretching and curing. The simulation results showed that a bigger α and θ led to a greater difference in flow velocity on the PDMS stamp surface; greater flow velocity difference could affect the adhesion of DNA (subsequently compromising the formation of the nanochannels). As suggested by our experimental data, longer nanochannels (3 μm) displayed a wider range of stretching speed with yield rate >90%.

Abstract: A newly designed ellipsoidal electrode tool used for micro-electrochemical etching (μ-ECE) in a precise reclamation process that removes defective In2O3SnO2 conductive microstructure from the surface of LCD color filters is presented. The electrochemical removal of ITO film eliminates the danger of scoring the surface of the substrate. The efficiency of the electrochemical process, enhanced by the ellipsoidal shaped electrode, also allows the feed rate of the workpiece (display color filter) to be higher and this reduces production costs. In the current study, a higher current rating and a faster workpiece feed effectively resulted in more effective removal. An ellipsoidal anode with a small major axis coupled with a narrow gap between the cathode and the workpiece also reduces the time taken to remove the In2O3SnO2. An ellipsoidal anode with small minor axis also provides better discharge mobility and removal. A thin cathode or one with a small arc radius also gives a higher removal rate for In2O3SnO2. The effective ellipsoidal anode provides more discharge mobility and removes the In2O3SnO2 easily and cleanly in a short time. The surface roughness, the average light transmittance and chromaticity of the three primary colors is also maintained at the same level after the μ-ECE process as it was before the removal of the ITO.
