Design and Implementation of Stackable VoIP Gateway;

Substantial size reductions are achieved and interconnecting usability and accessibility are increased by using of the 3D stacking packaging configuration, which is one of the most important trends of the novel packaging technology.

Cigarette cartons are conveyed onto stacking unit through the infeed conveyor belt,then pushed into opened case with inner flaps of the case cover folded,the out-flaps are folded after heating melt glue is sprayed on the inner flaps,and in the end,the codes are printed in the case.

Based on different friction coefficients between touchable feet and touchable face when actuator moved toward right and left,a suit of inertial linear actuator driven by piezoelectric stack with changeable friction coefficients was designed and manufactured with piezoelectric stack and mass as power devices.

Based on piezoelectric precision drive technology,a hydro-pump using a piezoelectric stack as actuator and a flexible hinge as magnifieation mechanism was prototyped and tested.

In the interest of getting good performance of speed and loading capability of the micro motor, at the same time ensuring the high rotary resolution, put forward a kind of new precise rotary motor using piezoelectric stack as actuating element based on inchworm motion.
