Modeling and Development of Gap Adjustment Automatically Technology for Offset Machine GAO Zhenqinga, WANG Yiming and BAI Jianjun College of Information and Mechanical Engineering Beijing Institute of Graphic Communication Beijing, China aemail: gaozhenqing@bigc.edu.cn Keywords:Offset Machine; Key Parts； Gap； Adjustment automatically.
Introduction As the complexity of the offset printing and the particularity of the prints and printed materials, the process of printing depends on plenty of adjusting devices which adjust the key parts for the machine run normally.
In most cases, the manual mechanical structure are used in the adjustment process for key parts, precision and efficiency are lower.
Studied object in this research is cylinders of offset machine，the principle of other key parts is same.
(2) Parameter output: output the gap state of the key parts

The thickness of insulation materials in Germany has gradually increased from only 4 cm to no less than 10 cm regardless of the type of material.
With a thermal conductivity between 0.007 and 0.009 W/(m∙K), vacuum insulated panels provide insulation performance ten times better than that of conventional insulation materials.
There are commonly two types of materials for roof insulation.
The floor insulation thickness is at least 25 cm. 3) Airtightness To ensure the completeness of thermal insulation, key locations including window openings, air conditioning bracket, service penetrations, roof joints and building corners must employ suitable sealing materials and thermal insulation. 4) Thermal bridge treatment To make the thermal insulation systems work well, not only should insulation materials and thickness be carefully selected, but also design and construction of key joints to avoid thermal bridges.

Reverse Engineering The reverse-engineering technology calls the self-examination technology or the reverse engineering.
Reverse Engineering mainly includes Reverse Engineering of images, Reverse Engineering of software and Reverse Engineering of machines, etc.
Nowadays, most study on reversing engineering focus on material object reversing Refactoring [1].
Cad model (curve and curved surface) technology is a key technology of reverse engineering[2] . 3.

The Applications of the Electron Beam Machining Technology in Research of Materials Science Hang Li, Hailang Liu, Haihua Yu, Yiping Huang (Institute of Electrical and Mechanical Engineering, Guilin University of Electronic Technology, Guilin 541004, China) email: 843174150@qq.com, email: liuhl@guet.edu.cn, email: 413810615@qq.com, email: hyp@guet.edu.cn Key words: Electron beam, Materials processing, Surface treatment Abstract.
When electron beam bombards materials, electronic and metal collision lose kinetic energy, most of the energy is converted into heat, cause the local temperature of the materials rising sharply and melting, even gasification and have been removed, so as to realize the material machining.
The main applications of EDM in the field of materials research The application status.
Three beam material modified state key laboratory of dalian university of technology used electron beam to irradiate the material surface to study the material surface modification.

Enhanced Piezoelectric properties of Barium Titanate Single Crystals by Domain Engineering 〇Koichi Yako, Hirofumi Kakemoto,Takaaki Tsurumi, and Satoshi Wada Department of Metallurgy and Ceramics Science, Graduate School of Science and Engineering, Tokyo Institute of Technology,2-12-1 Ookayama,Meguro-ku,Tokyo 152-8552 Keywords: d33 piezoelectricity , engineered domain , barium titanate, single crystal , domain engineering ABSTRACT Engineered domain configuration was induced into barium titanate (BaTiO3) single crystals, and the d33 piezoelectricity was investigated as a function of domain size.
INTRODUCTION In ferroelectric single crystals, high performance of piezoelectric properties appears by domain engineering.
These ultrahigh piezoelectric properties were originated from one of the domain engineering techniques, i.e., "the engineered domain configuration"[5-6] "Engineered domain configuration" technique uses the anisotropy of the ferroelectric single crystals. [7-8] BaTiO3 crystal is one of the typical lead-free ferroelectrics.
