Title: Monocrystal preparing apparatus
Inventor: ONO KENGO
IPC: C30B15/20
Filed: 1979-05-15
Abstract: PURPOSE: To control the generated damage to a min. degree by a method wherein, in case of growing a monocrystal by a rotary draw-up method due to an automatic diameter control technique, the interrupted time of a monocrystal draw-up operation caused to the trouble generation is detected in an early stage and the control is switched to the preliminarily set condition.  
     CONSTITUTION: The wt. of a molten liquid 2 within a crucible 3 is detected by a load detector 9 and the detected output is compared to an objective wt. signal which is the output of a wt. programmer 11. So as to regulate the difference to zero, a high frequency current is increased or decreased by a regulater 13 to control the diameter of a crystal 1. In this case, the deviation of the output of an amplifier 10 against the output of a programmer is detected by a meter relay 16 and, if said deviation exceeds the preliminarily set threshold value, a sequence circuit is operated to interrupt the automatic control of a diameter. A contact point 17, 18 of a multi- contact electromagnetic relay (X 2 ) are coacted, that is, a draw-up motor 7 is temporarily switched from an electric source 20 to 21 by a contact point 18 to be rotated in a high speed and a crystal 1 is separated from a molten liquid and, at the same time, the control is switched to a programmer 19 at a contact point 17 and said crystal is transferred to a temp. lowering procedure based on the output of this separately provided programmer 19.
