Abstract: Electroactive polymers, or EAPs, are polymers that show an adjustment fit as a fiddle when invigorated by an electric field. Ionic polymer metal composites (IPMCs) are electro-dynamic polymers with great electromechanical coupling properties. They are proficient applicants in many progressed innovative applications, for example, actuators, artificial muscles, biomimetic sensors, and so forth. Type of membrane and electrodes determines the morphology and structure of IPMCs. IPMCs can be prepared using physical loading, chemical deposition and electroplating methods. The assembling of anodes for IPMCs is exceptionally basic in their electromechanical coupling. Optimization of force, determination of cations and molecule size dispersal inside the IPMC structure, and so on are the different components, which decides their proficiency. An ionic polymer-metal composite (IPMC) comprising of a thin Nafion sheet, platinum plated on the two side faces, experiences extensive twisting movement when an electric field is connected over its thickness. Then again, a voltage is created over its appearances when it is all of a sudden bends. IPMCs are best known for their proving advantages such as biocompactible, low activating voltage and more power efficiency

Abstract: This research introduces KPS (Korea Production System), which is a type of manufacturing innovation methodology. The KPS has been developed by KPC (Korea Productivity Center), which is a special corporation with the objective of industrial productivity improvement. In this paper, we show theoretical validity of the KPS, in which there are 6 principles (People Involvement, Field Standardization, Continuous Innovation, Flexibility of Production, Commercialization of production Information) and thirty core activities based on the above 6 principles, and the KPS has a list of 140 assessment items for evaluations of the above core activities. In addition, we summarize some differentiations between the KPS and other manufacturing innovation methodologies. During the past three years, the KPS has been used in productivity innovation partnership program between major companies and SMEs (small and mediums-sized enterprises) in Korea. In this program, the KPS has been applied in production lines of various SMEs, which are almost cooperative firms of global and major companies such as Samsung elec., POSCO, LG elec. and so on. To show the effectiveness of the KPS, we introduce outcomes of some real implementation cases in the production lines of SMEs, finally.

Abstract: The traditional contact measurement in contemporary industrial technology high speed development situation has been unable to meet the need of measuring field. Laser displacement sensor as a non-contact measurement rookie, because of its various measurements has been widely applied to various measurement. Based on the analysis of the measurement and analysis of the principle of laser displacement sensor and its components, established the mathematical model of measuring principle, has guiding significance for beginners.

Abstract: Themain content of the construction project cost management including costforecast, cost plan, cost control. Do cost forecast, cost control goal set,must be ahead of the labor, material, cost forecasting, construction scheme ofchange of the cost forecast and the prediction of auxiliary construction cost.Cost control should follow the principle of conservation and comprehensivecontrol, there are some effective ways to realize the cost control, forexample, take organizational measures to control the project cost, take technicalmeasures to control the project cost, to take economic measures to control theproject cost, strengthen quality management and control of rework rate, etc.

Abstract: This topic through to the automobile air conditioning working principle and the structure analysis of air conditioning assembly, with AT89C52 as the core of single-chip microcomputer control system is designed, and the controller hardware and part of the circuit design; To realize fuzzy control algorithm of the control system is established. Expounds how to realize the automation of automobile air conditioning system of fuzzy control; Temperature detection with high precision integrated temperature sensor MF51 implementation; Programming process, adopts the modular design method of each module respectively for programming, debugging, then connect them in accordance with the requirements of control, the debugging, analysis.

Abstract: CAI is a product of the era development and the problems in the process of its advancement which exist in the understanding and the resource reserve are inevitable. For these phenomena, not only the auxiliary and order principle are supposed to be established in the process of applying the computer technology in teaching, but also the CAI's application value ought to be reexamined. The specific training to teachers of different subjects needs to be strengthened and the construction of CAI network database should be consummated in time.

Abstract: This paper mainly introduces the related theory and method of cylindrical gas film seal, the structure and principle of the cylindrical gas film seal, and solving the mathematical model, introduces several methods commonly used for solving the gas film pressure, and compare these methods, get the applicable conditions and calculation error of these methods.

Abstract: The structural layout and basic principle of a four-coordinate CNC device mounted on a common CNC milling machine was introduced, with it four-coordinate workpieces can be machined by a single setup,which can reduce costs and improve efficiency.

Abstract: This paper discusses on the protection significance, contents and principles of ancient architecture in China, and reveals current protection problems. By taking the Ming and Qing dynasty’ street in River town in Xiaochang for example, it is analyzes the local protection attitudes and principles. The ultimate purpose of the article is to show the protecting importance of ancient architecture, and discuss the general protection method.

Abstract: There are something wrong with traditional hot rig.Such as poor efficiency,low precision,exploding diamond easily,rickety hotting diamond and so on.Introduced operational principle of mechanism,electronical control of ultrasonic and pneumatic principle.The machine use only one stepper motor to realized inhaling diamond linkage’s swinging and location,and then the structure is simple and reliable.
