Abstract: PURPOSE: To obtain high density and high purity fused quartz by grinding the aggregate of fused silica particles obtain. by heating silica flour particles.  
     CONSTITUTION: The silica flour particles 1 of a relatively low density entrained in oxygen 2 and hydrogen 3 are introduced into a fusing furnace 4 and are heated and melted in a flame of a high temp. consisting of the hydrogen 3 and the oxygen 2 to form the fused silica particles having the relatively high density and to cause the surface bonding thereof, by which the aggregate of a honeycomb structure having a degree of fusion of ≤25% in a volume ratio is obtd. Next, this aggregate is gathered in a collecting step 5 and is sent to a grinding step 6 where the aggregate is subjected to frictional crushing and thereafter, the aggregate is classified by a classifying machine 8. The particles of the sizes larger than standards are returned through a cycle line 10 to a grinding step 6. On the other hand, the objective size particles 9 are sent to a firing machine 7 and are calcined at 500 to 1000°C, by which the wear resistant material is removed.

Abstract: PURPOSE:To prevent a flicker from being caused even when light of long wavelength arrives, by driving a pickup unit with driving pulses which are at a low level at any time except when charges are transferred from a vertical transfer register to a horizontal transfer register.
