In connection with the scope of characteristics mapping of line drives, adopted in the analyzed case, at the presented defining of components of the “link” type it has been distinguished 4 drives of this type and namely: L_04_1; L_04_2; L_07_1 and L_09_1 (Fig. 2).
Structure of the control program and displacement characteristics of motor motion Whereas the course of the process of control program realization, provided that the signal from the sensor signaling the presence of a product for packing is obtained and displacement characteristics of motion of particular motors are generated for proper global variables, can be presented in the following steps (Fig. 3): - moving out of the (J_07_1-07) motor with the stroke of 500 [mm]; - displacement of the (J_04_1-04) motor with the value equal to 400 [mm]; - moving out of the (J_04_2-04_01) motor with the stroke of 400 [mm]; - standstill related with the element gripping; - moving in of the (J_04_2-04_01) motor; - moving in of the (J_07_1-07) motor; - displacement of the (J_04_1-04) motor of 800 [mm]; - moving out of the (J_04_2-04_01) motor with the stroke of 400 [mm]; - time standstill; - moving in of the (J_04_2-04_01) motor; - displacement of the (J_04_1-04) motor of 400 [mm]; - moving
out of the (J_09_1-09) motor with the stroke of 4250 [mm] under the condition of obtaining the signal from the sensor signalizing the presence of an object; - time standstill; - moving in of the (J_09_1-09) motor.

Fig.1 31P MAS NMR spectra of the glass series (C) xLi2O-(50-x)PbO-20B2O3-30P2O5.
Raman spectrum of the lead glass 50PbO20B2O3-30P2O5 shows a broad high-frequency band with the maximum at 1011 cm-1 the position of which is characteristic for the presence of Q 1 units.
In the middle-frequency region there are several small bands showing with increasing Li2O content a steady increase in the relative strength of two bands at 634-655 cm-1 and 736 cm-1.

The characteristic bands for PO43- appeared at 604cm-1, 561cm-1, 1111cm-1, 1030cm-1.
Bonds at 870cm-1, 1455cm-1 and 1420cm-1 correspond to CO32- demonstrating that the material contained traces of carbonate which similar to composition of natural bone apatite.
The bands at 804 cm-1 and 478 cm-1 assigned to stretch vibration of Si-O bond.
Peaks at 474cm-1, 812cm-1, 1111cm-1 and 3431cm-1 increase in intensity because similarities in vibration between SiO4- and PO3- [11].

Experiment also found that when the CV<1 hydroxyl free radical production is higher,when CV>1 hydroxyl free radical production with the increase of the cavitation number range is very slow.
According to the literature[8] CV is around 1.0,cavitation effect is best.But in general,if you want to get the best cavitation effect,control flow conditions and geometry size are needed to keep CV<1.

Results and analysis Surface Morphology (a) (b) (c) (d) Fig. 1: AFM images of copper-coated polyester fibers (a)untreated;(b) plasma treated for 3min;(c) plasma treated for 6min;(d)plasma treated for 9min The AFM images of 5.0×5.0μm2 in Fig.1 reveal the surface structures of the copper-coated polyester fibers before and after O2-plasma treatment,as presented in Fig.1.
Fig. 1(c) and Table 1 show some larger and compacter clusters are formed on the fiber surface after plasma treatment for 6min.
It is attributed to roughening of the fiber surface by plasma treatment [10], as shown in Table 1.
