The study orientation of HIL mainly has involved such two aspects as the material technology research and the laser measurement and control technology research in the recently three years
　　 I. Material Technology Research: Materials modification and chemical vapor-deposition diamond　　Materials Modification
　　We have engaged in the plasma technology research for many years. By use of the plasma technology, the surface of the material can be modified. The heat processing is conducted on the metal materials or non-metal materials by use of the high-temperature plasma airflow, thus the material performance is modified to make it own higher value in use. To process the metal material by use the technology, the hardness of the material can be strengthened to make its abradability more powerful. We have applied for an invention patent “One type of approach and device heating metal part by use of magnetic-control electric arc plasma”, which is mainly used for the plasma processing roller technology. On the basis of it, the applications in relevant fields are developed. Meanwhile, by use of the technology, explore and research the heating processing effect on the non-metal super-hardness material under conditions of deoxidization or oxidation, so as to modify its performance and enhance its value in use.
　　Chemical Vapor-deposition Diamond
　　There are mainly two aspects of researches on the item from now on. One aspect is the application base research, which includes: the diamond deposition mechanism, the diamond abrasion mechanism and the diamond material performance researches; the other aspect is to conduct the application research, which includes: the electric conducting diamond preparation, non-recycling chemical vapor-deposition diamond equipment and so on.
　　II. Measurement and Control Technology
　　The laser measurement and control technology is mainly used to exploit the new products on the original base. The measurement technology was pioneered newly from 2006. The researches which have been undertaken include: the automatic measurement for the glass tube mouth damage, the triangular displacement technology and X-ray non-destructive measurement technology.
　1. New Product Development on Existing Base
　　The development and the application promotion of the glass tube laser wall-thickness detector. The instrument adopts the double traverse laser measurement principle and the linear-array CCD, the computer and other technologies, supported by the rotational measurement mechanism, to complete non-contact and high-precision measurement on the wall thickness of the entire glass tube round. Its applications include two parts: One is to combine with the glass tube laser separator, meanwhile, complete the measurement of the diameter and the wall thickness, providing an effective means of measurement for the production of the high-quality energy-saving fluorescent lamp tubes. Currently, the on-site application of the product is very good. In addition, the technology will be used for the glass tube wall thickness measurement and the separation control on the production line of the linear drawn tube. Therefore, the technological improvement designs are needed to meet the specific requirements of users.
　　Serialization of Laser Diameter-measuring Products
　　On the basis of the original single direction (one-dimension) laser measurement, we have completed the development of two-dimensional laser caliper and it has been applied to the rubber products manufacturers. We will carry out the large-size laser caliper this year to meet the demands of the customers for the large laser calipers.
　　2. New Technology Research Development
　　The application research of the laser triangle displacement testing technology in the film measurement.
　　The laser triangle displacement detection technology is the application in the displacement detection with the combination of the laser, PSD (Position Sensitive Detector), integrating and the computer technology. In light of the film detection requirements of Baoding Lucky Film Factory, we have begun the implementation of the film detection project, and on this basis, we open up the new application field of the triangle displacement detection.
　　The development and the application promotion of the horn tube microcomputer imaging detection system.
　　The imaging system is used for the on-site quality testing on the horn tube of the energy-saving lamps manufacturers. The system is based on the precision machinery, the optical imaging, the area-array CCD detection, the automatic control and the image processing technology to complete the on-line detection and screening of the horn tube size (the exterior diameter, the height, the wall thickness and the roundness ratio) as well as the defects (crevasse, crack, material amassing and twist).
　　Nondestructive testing research by use of X-ray.
　 　With the rapid development of the industrial technologies and the economy, the requirements for the product quality become higher and higher, while China’s nondestructive testing technology develops relatively late, restricting the industrial development. Aiming at cable nondestructive testing research in the cable industry, by use of X-ray imaging technology we can observe and measure the eccentricity without damage of cables. The technology features in high testing efficiency, causing no waste. Through the computer control technology, the online testing and control of the cable production can be achieved. The technology can also be used in the research for the board or wall thickness measurement of metallic and non-metallic products as well as the internal defect detection of metallic and non-metallic parts.
