The OSRAM name was registered in 1906 by Auer-Gesellschaft. The name OSRAM derives from the names of two elements: Osmium, a metal; and Wolfram, the German word for tungsten. The company had been a pioneer in the development of the Osmium lamp and the tungsten filament lamp.
transition is. Thus, the human labor in virtually all industries, automated machinery, robotics, computer operations have been replaced by a precision machine. For example, in the automotive industry, the entire automobile production workers' wage share of the cost of only about 6% and this rate is still lower. Thus, the share of wages in all industries, and this situation is gradually shrinking
