Revised adhere to in accordance with rules governing the party and party with morals in combination, for at the present stage, the leadership of the party members and cadres and Party members in existing main problems of self-discipline, put forward principles, requirements and specifications, showing Communists noble moral pursuit, Five is higher than it is proposed that the focus on the expanded to moved to the provisions of the present at all times and in all over the world ethics from high from low common requirements. One is closely linked to the honest self-discipline, removal and no direct relationship. Second is to insist on a positive advocate, eight prohibition 52 allowed the negative list content synchronization amendment disciplinary punishment regulations. For all the party members, the applicable objects from the Party member cadre of leaders of all Party members to fully reflect the overall strictly. Four is to highlight the vital few , seize the leadership of the party members and cadres of ordinary Party members. Delete complicated on Jane, and strive to achieve concise, easy to understand, easy to remember. The revised is ruling party since the first adhere to a positive advocate, for all members of the self-discipline norms, moral declaration issued to all members of the party and the National Peoples solemn commitment. How to understand the show the Communists noble moral pursuit comprehensive strictly necessary according to the rules governing the party and party with morals in combination, the de is mainly the purpose of ideal and faith in the party. The traditional culture of the Chinese nation has always stressed the importance of dependent Germany and France, de treatment ritual order. Partys eighteen years, the Central Committee of the Communist Party of China outstanding emphasize the construction of honest politics, so that cadres honest, clean government, political pure brightness, and the party members and cadres honest self-discipline raised the a series of positive requirements. At the same time, from the perspective of the nature of the party, the Communist Party of China is the vanguard of the Chinese working class, is the vanguard of the Chinese people and the Chinese nation, the party as a An advanced political organization, to establish the image of clean and honest, not rot, not rot, do not want to rot in the effective mechanism must strengthen the positive lead, of its members from the front clear clean fingered self-discipline code of conduct. openingManipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation. Industrial automation technology has gradually matured, as mature a technology line has been rapid development in industrial automation as a separate subject. Manipulator application began to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gases, high radiation case, robot in similar circumstances showed great use also brings great convenience to the staff. Precisely because of this robot to get peoples attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller) is in various special circumstances and under special conditions set for mechanical devices. Now turned on the development of the microelectronics automatic control technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful development, now continues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of industrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. Today, the high level of automation combined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control. This of design let designers on in school by learn of has a must of consolidation, understand has some usually didnt opportunities awareness in world range within some leading level of knowledge has has must awareness, hope designers can in yihou of design in the can success of using in this design in the proceeds of experience 1.2 manipulator in both at home and abroad of research profile automation mechanical arm research began Yu 20th century medium-term, after years with with computer and automation technology of development, Makes mechanical arm on the Grand stage of industrial automation and shine, gradually became an industrial evaluation standards, and its importance can be seen. Now original robotic arm spent most of mass production and use on the production line, which is programmed robotic arm. As the first generation of manipulator position control systems main features, although not back several generations that can detect the external environment, but can still successfully complete like welding, painting, delivery as well as for materials simple movements. Second generation mechanical arms are equipped with sensors and manipulators have the environment there is a certain amount of sense, when the mechanical arm is to use the program as a basis.
