发明名称 SYSTEM FOR CRUSHING AND SORTING CONSTRUCTION WASTE
摘要 A color cathode ray tube is provided with a saddle-shaped shadow mask. As a result, the sensitivity to doming and microphonics of the mask is improved. This is advantageous, in particular, for a cathode ray tube having a very flat display window. Preferably, the display device in which the cathode ray tube is employed is provided with two dynamic quadrupoles, for example, in front of the electron gun and in front of a deflection unit.
