allows you to quickly verify the health of the quartz resonators. Diagram of the device consists of a generator (T1), detector (D1, D2) and DC amplifier (T2). By connecting the quartz to the two terminals of the generator, the power on. If the resonator is OK, resistor R2 appears to the high-frequency voltage which is then fed to diodes D1, D2 for detection. Highlighted in this case a constant component opens the transistor amplifier stage. Load UPT serve milliammeter ИП1 and lamp L1. The glow lamp indicates the functionality of the quartz. But his activity is judged by the readings of the milliammeter. For the active resonator current is 70-90 mA, and for inactive — 30-40 mA.

The idea is to make the car the most I had in those days, when “the Zhiguli””Muscovites” and even “the Cossacks” could be bought only after standing for many years in the queue. Then came other times, and the car ceased to be a deficit. There are so many makes and models, what to choose-that became difficult.
Carrier-based fighter F4U-5/7 CORSAIR. In the annals of aviation are not many aircraft left in her mark. But it is to such aircraft include the American fighter F4U CORSAIR the Chance Vought company, which had a great influence on the outcome of the air battles over the Pacific.
Sports model missiles Ѕ6В champion of Russia S. Romaniuk (G. Uray) — a graphic representative of the aircraft’s so-called “Ural” scheme, the author and developer of which is a team of rocketmodeler city of Chelyabinsk under the leadership of the deserved trainer of Russia V. I. Tarasov. Its main feature — an extended tail cone. Its length is 115 mm. In the rest of the model is made according to fairly well-known technology.
The competition of the State Committee on aviation technology to establish the impact of a missile to destroy aircraft carriers was announced in September 1961. In the fight for the prestigious order entered OKB A. N. Tupolev, F. S. Yakovlev and P. O. Sukhoi. In the autumn of 1962 was held on advanced Scientific-technical Council, which commissioned the development of a conceptual design of the aircraft design Bureau of P. O. Sukhoi.
Machinery and apparatus air cushion (profit centers and WUAs), every year more and more attracted the attention of designers all over the world. This is not surprising. The use of the inherent principle, especially for all-terrain vehicles, allows us to obtain unprecedented off-road capability and speed. They can freely and equally easy to move on the highways and country roads, marshy bog, on the water surface and a plowed field.
The debut of this most powerful and most expensive car that produces the famous Italian firm, was held in January 2004 at the prestigious Detroit motor show. The machine will replace produced with the 1992 FERRARI 456 GT.
Throwing glider pioneer. Non-motorized model glider is very popular among modelers. Made in the form of models of monotypes, throwing gliders allow for fun competitions on the range, while models in the air or on landing accuracy.
