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

Abstract.
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.

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.
