Title: Single crystal manufacturing device
Inventor: SUGITA YOSHIMITSU
IPC: H01L21/208
Filed: 1979-04-23
Abstract: PURPOSE: To shorten the time required to manufacture a single crystal and enhance the quality of the crystal by monitoring the concn., grain size, etc. of SiO powder in a furnace and controlling the vol. of inert gas to be fed into the furnace in accordance with the monitored values to reduce the number of repulling times.  
     CONSTITUTION: Seed crystal 9 is attached to chuck portion 8 of pulling shaft 3, and after dipping the bottom of crystal 9 in silicon melt 10 crystal 9 is slowly pulled to manufacture single crystal 11. In this process the concn. and grain size of SiO powder in exhaust gas are monitored, and crystal 11 is manufactured while maintaining the concn. and grain size lower than set values at all times. When the concn. is higher or the grain size is larger, in accordance with the detected values of dust monitor 14 flow rate controller 16 is controlled with control device 15 to feed much Ar gas into furnace 1, thereby quickly exhausting SiO powder and SiO vapor from furnace 1. When the concn. of SiO powder is lower and the grain size is smaller, the vol. of Ar gas fed is reduced.

Abstract: PURPOSE:To increase flashing speed while reducing lighting rate to facilitate the confirmation of flashing by providing a comparator for comapring current in a display element with the reference current and an oscillation circuit for comparing threshold voltage with voltage across a time constant circuit. CONSTITUTION:When a switch S1 is turned either left or right, output 4 from a nonstable oscillation circuit constituted from an amplifier A2 and ambient circuits operates a relay RY to close a switch SRY and turn on and off incandescent lamps L1-L3 or L4-L6. An amplifier A1 is a comparator constituted from a difference amplifier used for detecting load current (or for detecting disconnection of wire) and compares voltage applied to the positive input terminal 6 of the amplifier A1 with the threshold value voltage. Also, the amplifier A1 is subjected to negative feed-back in the interior to constitute as a whole a logarithmic conversion circuit. Thus, the change of current in the incandescent lamp changes the threshold voltage of the oscillation circuit according to the output of the comparator to thereby change the flashing speed and lighting time.
