Appearance and many of the technical characteristics of the SUV, created basically to overcome the terrain, are already present today in the prestigious universal car that perfectly behave on the roads. The ancestor of these machines is quite rightly considered the released in 1994 it was an asphalt all-wheel drive TOYOTA RAV4, which is the abbreviation of RAV in the name comes from the Recreation Vehicle, which translates as “the car to stay”. The idea of pseudogap picked up dozens of road companies, so that the RAV4 appeared soon a lot of followers.
Even in the recent past 10АС9 sound system, each sound column which contains two versatile dynamic loudspeaker (one for low and medium frequencies and the other, with a diffuser of smaller diameter for higher), it was considered perfectly acceptable for a home stereo. And electrical parameters it was on a high level: power 10 W, impedance DC current 4 ohms, audio frequency response 40 to 18,000 Hz. With the advent of so-called Hi-Fi equipment these speakers have become increasingly depart among the almost Museum pieces.
Inspired by the originality of technical solution, published in the journal “modelist-Konstruktor” No. 11’78, I modified the circuit for fluorescent lamps and for many years its use in residential lighting fixtures. As in the prototype, economical and not scarce ЛДЦ40 (ЛДЦ80) light up instantly, their work is not accompanied by annoying clicks and “wink” for missing an unreliable starter. And best of all — for such lighting you can even use the bulb.
On the roads and cross roads of Latvia in recent time, new sporty micro cars — buggy, built at the Central station of young technicians of the Republic. One of them — school “Buggy-350” has been awarded to a screening at the NTTM-74. These nimble, agile machine with the same success moving on dirt roads, highway and rugged terrain.
