摘要: A crucible is situated in a vacuum chamber and provided with a feeder for granulate material, heating elements for melting the material, and a crystal puller above the crucible. Measuring elements provide signals for a controller including a fuzzy processor utilizing an empirically determined data field to output a signal for the material feeder.
