Title: Apparatus for producing semiconductor single crystal by continuous charging method and production thereof
Inventor: KUROSAKA SHOEI
IPC: H01L21/208
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a semiconductor single crystal from having the dislocation by liquid level vibration at the time the melt surface falls and a raw material supplying pipe detaches from the melt when the raw material supply ends in production of the semiconductor single crystal by a continuous charging method. SOLUTION: The bottom end face of the raw material supplying pipe 24 to be mounted at the raw material supplying section of the apparatus for producing the semiconductor single crystal is inclined at a prescribed angle θ from the axial center of the raw material supplying pipe 24 and further, the bottom end face is provided with a notch 24a. The notch 24a initiates the detachment of the raw material supplying pipe 24 from the liquid at the time the pipe detaches from the melt by falling of the melt surface, and further, the detachment thereof from the liquid is improved by the inclination of the bottomed face. Then, the fall of the melt lifted by adhesion to the bottom end face of the raw material supplying pipe and the consequent occurrence of the melt surface vibration encountered heretofore do not arise.  If the pressure of the raw material supplying section is equaled to the pressure of the crystal growing section after the end of the raw material supply, the melt level in the material supplying pipe falls and, therefore, the detachment of the pipe from the liquid is additionally improved.

Title: Loop gain setting method for focusing servo loop
Inventor: ISHII HIDEHIRO
IPC: G11B19/06
Filed: 1989-03-18
Abstract: PURPOSE:To automatically set the optimum loop again by setting a loop gain based on plural sampling values representing the magnitude of the amplitude of a focusing error signal. CONSTITUTION:A system controller 7 repeats up-and-down motion against the focusing position of an objective lens for several times by driving rotatably a spindle motor 2, and fetches values representing the magnitude of the amplitude of the focusing error signal obtained at that time as plural sampling values. And the loop gain can be set based on the maximum value out of those plural sampling values. Therefore, since the level of a noise is low even when the noise similar to an S-curve due to a flaw or dust on a disk, etc., generates, it is not erroneously detected as the original S-curve of a focusing error. Thereby, it is possible to automatically set the optimum loop gain regardless of the fluctuation of a power in a light source or dispersion in the reflectance of the disk, etc.

Title: Deodorizing apparatus
Inventor: SATOU YOSHIO
IPC: B01D53/77
Filed: 1983-04-16
Abstract: PURPOSE:To prevent the discharge of a deodorizing liquid to the outside of the apparatus by communicating the water accumulating part of water content separating chamber with an air suction pipe through a communicating pipe, and returning a deodorizing liquid, which accumulates in the water accumulating part, to a deodorizing tank with the negative pressure caused by the flow velocity of the odorous air in the air suction pipe. CONSTITUTION:A water accumulating part 28 at the lower part of a water content separation chamber, which is partitioned with an inner cylinder 6, an outer cylinder 7, and a bottom plate 25, is communicated with an air suction pipe 8 through a communicating pipe 29. The water content of the deodorizing liquid in the waste gas, which is deodorized by mixing with the deodorizing liquid spouted from a spout 17, is accumulated at the lower parts of water content separating chambers B-F. The water content, accumulated in the water content separating chambers B-E, is returned to a deodorizing liquid tank A with its own weight. Since, in the waste gas from a vacuum tank, the pressure of the projected part of the communicating pipe 29 in the air suction pipe 8 is lower than that of the inside of the water content separation tank F, the water content, accumulated in the water accumulating part 28 of the water content separating chamber F, is sucked into the air suction pipe 8 and returned along with the odorous waste gas to the deodorizing liquid tank A. In this way, the deodorizing liquid is never disharged into the open air.
