local-local link
7.A rovel architecture of parallel machine tool based on 6- mechanism is presented.By using the theory of parallel robotic mechanisms,the local payload index of the ma chine tool situated at the initial a embly configuration is defined and the relatio hi between the local payload index and the link lengths are analyzed,which is useful for the optimal design and a lication of the machine tool.
8.This artical introduces a method of the local network system design of microprocessor andthe way to realize it in small hydraulic power stations and the other industrial production units. The D LINK network system which is popular and less cost, is adopted for this local network system. Therefore, the D-LINK network system makes the operation caster, more reliable, has greatlyextented capacity.
10.Since September, SMEs could access local and global business contacts through the TDC-Link free of charge and at a nominal fee respectively.
