In the age of microelectronics, computerization and display multimeters gauges perceived by some almost as an anachronism. However, life proves the fallacy of such views.
Kids especially like the dynamic, moving toys. Even more the ones they made themselves or with the help of adults. And especially if the object of the game is associated with some of the popular fairytale or cartoon character. Among the latter children was always fascinated by circus performers — smart, brave, funny and cheerful.
Replacement flyback transformer in TV monitor МС6105 with CRT 31ЛК is, of course, not a major overhaul. Moreover, if the old monitor staff “strojnik” cope with the work, and to change this (very expensive, cranky and hygroscopic) node to the new is hardly appropriate.
It is known that in the process of operation of car batteries is required from time to time to do preventive charge-discharge cycles to prevent sulfation of the plates and thereby increase their service life. There are lots of devices, including homemade (see the journal “modelist-Konstruktor” No. 9— 11 ’01), through which the battery is initially discharged to 10.5 V with a current of 1/20 of its capacity and then the voltage on the terminals is communicated during the charge-discharge cycle to 14.2 to 14.5 V. And the ratio of the charge-discharge current components are in the majority supported almost perfect — 10:1, and the pulse durations of the charge-discharge — as 3:1, but…
Oddly enough, but until 1963, the famous Creator of the most prestigious racing cars, Lamborghini Ferruccio engaged in production… tractors. The reason for such a radical change it was a youthful fascination with the designer — in the distant postwar years he was engaged in the conversion of the serial “Fiats” in sports cars.
I. INTRODUCTORY session
Busy with household chores or interesting conversation, we forget, for example, on a boiling kettle. Time to remind him maybe a simple buzzer. However, the oscillators sound frequency (e.g. multivibrators) based on transistor logic or integrated circuits do not always meet their creators. The simplest devices give a smooth tone, barely visible against the background of everyday noise, and sudden and loud “beep-beep” of a more complex designs can scare.
Firm history John North Willis began with the acquisition in 1908 of a small automobile company Overland, which became known as Willys-Overland. The new firm first specialized in the production sports cars with 4-cylinder engines and planetary transmissions, however, soon created cars with a 45-horsepower motors and WILLYS OVERLAND SIX SIX. In 1913 the company sold about 35 thousand cars entered if the number of the leading automobile companies of America.
How to start a designer? In Latin the word “design” (constructio) means the preparation, construction. In technical language it includes concepts such as diagram of the device and operation of a machine, structure or site. Designs also referred to as the machines, structures or individual components and their details. In addition, the concept of “design” leads to and provides a very specific arrangement of parts and elements of the machine, method of connection, forms of interaction and, of course, the material from which the individual parts (elements) of the structure needs to be manufactured.
