Lapping system Evaporator with resistance heating Electron beam evaporator Annealing sytem Dye bonder, Wire bonder Structure measurement Quantum dots structure are measured by atomic force microscope.
A large number of tungsten carbide powder is used for making high-speed cutting tools, kiln construction materials, jet engine parts,metal-ceramic materials and resistive heating elements ect.; 2.
The resistance heating wires 76 provided in the six zones 711 to 716 are connected through power lines passing through the interior of the shaft 41 to a power supply source(not shown).
Each of the six zones 711 to 716 of the hot plate 71 has been heated up to a giventemperature by its own individually built-in heater(the resistance heating wires 76) in each zone(between the upper plate 73 and the lower plate 74).
