| Abstract | ||
| The use of electronic valves is commonly available. yet, the most common is the techniques of communications as prod casting transmitter that are used by these valves in addition to their use in communication tools as far distance telephone, electronic measuring techniques , and others.In this study, an attempt is endeavored for improving the efficiency of the vacuum micro- valves(GI-19b) through activating their internal surfaces by the use of ionic pumping which is used for treating valves which are out of order (because of sedimentation some materials and oxide on its poles). The existence of these materials and oxide increase the sum of current leakage moving in between. The use of ionic pumping method leads to direct high voltage on the poles since the sum of the current can be largely decreased. Besides, they are other methods for fixing valves up these valves.The practical result of measuring current leakage of the prepared valves proves there is improving of the measured valves; it is noticed that these valves are far less than these before treatment. This gives a clue of the positive effect of this method for fixing valves up. | ||
