Abstract: PURPOSE:To flatten the solid-liquid boundary of a pulling up crystal and to decrease crystal defects by supporting a inverted circular cone part for separating the raw material melt for pulling up a crystal by means of a supporting member immersed in the melt. CONSTITUTION:The raw material 7 coated with a liquid sealant 8 is housed in a crucible 4 housed in a susceptor 5 supported to a freely rotatable lower shaft 6. A forming body 12 of an inverted circular cone shape having a small aperture 13 at the front end is provided in the lower part of a cylindrical body 15 fixed with the supporting member 16 to a heat insulating material 10 in the upper part in such a manner that the top end of the forming body 12 is positioned at the boundary of the raw material melt 7 and the liquid sealant 8. A seed crystal 2 mounted at the front end of the upper shaft 1 is immersed in the raw material melt 7. The single crystal 3 is pulled up while the crucible 4 and the seed crystal 2 are rotated in opposite directions. The liquid level height of the raw material melt 7 in the crucible 4 is changed by relatively moving the forming body 12 with respect to the liquid surface of the raw material 7, by which the diameter of the liquid surface in the forming body 12 is controlled.

Title: Gamma correction circuit
Inventor: KENJIYOU YOSHITOYO
IPC: H04N5/202
Filed: 1984-07-10
Abstract: PURPOSE:To keep proper white balance by constituting the titled circuit that gamma correction is applied to each color display element of a picture and decreasing the gamma of a red display element less than the others when a luminance signal level is large so as to prevent blooming. CONSTITUTION:An (R-Y) color difference signal and a luminance signal fed to terminals 6, 7 do not conduct a Zener diode 10 at a pattern with low brightness and then the gamma correction is performed by resistors 4, 8, 9. When the pattern reaches a high brightness, the Zener diode 10 and the diode 12 are conducted. Thus, the apparent amplification factor of a Tr2 is reduced. This is equivalent to increase the resistance value of the resistor 4 and to apply gamma correction. Thus, the red beam current is smaller than the other beam current to reduce the blooming. Further, white color with a high color temperature is reproduced by suppressing the red beam current.

Title: Production of single crystal
Inventor: YASUDA SADAO
IPC: C30B15/20
Filed: 1978-11-24
Abstract: PURPOSE: To obtain a high purity silicon single crystal by heating the inside of a chamber covering a crucible, etc. to a predetermined temp.; detecting a point of time at which the concn. of CO in the chamber becomes a predetermined value or less; and melting raw material in the crucible.  
     CONSTITUTION: Raw material polysilicon is charged into a crucible in a chamber, and the chamber is hermetically sealed. By continuously feeding Ar gas and evacuating the chamber an Ar gas atmosphere is formed in the chamber, and the chamber is preheated to a high temp. just below the melting temp. of the solid raw material. The concn. of CO in the chamber is then monitored with a detector such as a gas chromatograph. After confirming a CO concn. peak of several hundreds ppm and detection-confirming a preset CO concn. of about 10ppm, the raw material is melted with a heater to produce a smiconductor silicon single crystal with a usual single crystal pulling device. As a result, unlike a convnetional method CO, CO 2 , etc. generated from the structure are prevented from dissolving in the molten Si, so high purity is provided to the single crystal.
