The durability of even the most modern electronic devices (EEW) is inferior to semiconductor counterparts. In most cases this is due to the emissivity of the cathode. The matter is further complicated by the fact that the diagnostic tool (commercially available instruments for measurement and control of emission current) is, unfortunately, very expensive, difficult to operate, as they contain a “naughty” anode and grid rectifiers, which are designed to create to check the lamp mode is close to the working. The received data are plotted, calculated certain characteristics, and by means of which required parameters.THE SUITABILITY OF THE TUBE?

Since 1936 the Automobile plant named after Stalin (ZIS) in addition to the famous “trentodoc” ZIS-5 was produced and Executive cars. The first limo was the ZIS-101, was designed by the factory team of designers under the direction of E. Vazhinsky. In the production process (until 1941) was released 8752 such machines.
I have developed a mini system is to automatically maintain the desired temperature and air humidity in the oven, covered boxes, as well as in greenhouses or other spaces. The design of it is basically block-aggregation (Fig. 1); mounting quite on forces to everyone who at least once in your life going even without soldering, and using connectors and twisting some simple electro – or radio circuit.

The protagonist of our next story — GAZ-67B, one of the cars of that specific type, which during the last war became known as “jeep”. But even a few years before this model appeared design, which had Quite a big impact. Therefore, “Spent the summer of 1938, when Gorky automobile plant was built the first prototypes of the “emka” with all driving wheels.

We have already talked about a jeep-climber, which could become a new kind of mountain transport (see “M-To” No. 12 of 1974). But machine-controlled trucks will be able to find application in the polar regions — to move through the ice zamorochena fields, and on water. At first, perhaps, as a small vehicle polar explorers and, later, as special cargo trasport type “water — ice” for the developing regions of Siberia and the North.


The F-86 sabre, built by North American over half a century ago, without any exaggeration, is the most famous American jet aircraft of the last century. Widespread fame brought him not only the Korean war, which began his fighting career, but also huge volumes of serial production, only built more than 7000 pieces. The last flying F-86 was withdrawn from service in 1993, setting a record in flight longevity, and several fighters who are in private collections, fly so far.
