摘要： PURPOSE: To check the deterioration of a seed crystal and to prevent the deterioration of a single crystal which is pulled up by providing a cooling means for protecting the seed crystal before and the seeding is carried out in the titled device for growing a single crystal by a pulling method.
CONSTITUTION: A crucible 6 is arranged in a pressure vessel 5, a semiconductor material is charged into the crucible 6, and the material is heated by a heater 7 and melted. A pulling shaft 1 is then lowered, the seeding is carried out by a seed crystal 2 attached to the leading end of the shaft, and a single crystal is pulled up. In this case, the seed crystal 2 before the seeding is carried out is cooled by a refrigerant circulating through the inside of a refrigerant circulating pipe 3 which is coiled around the side periphery of the seed crystal 2. Consequently, the formation of chapping on the seed crystal 2 before the seeding is carried out due to the heat on the crucible 6 side which is transmitted by convection and radiation to the crystal is prevented. Accordingly, the deterioration of a single crystal which is pulled up can be prevented.

摘要： PURPOSE: The value which is obtained by measuring the distance between the side face of the single crystal and the side wall of the crucible opposing to the crystal by roentgenographic pictures is subtracted from the radius of the crucible to detect the outer diameter of the single crystal even with a beam width of X-rays narrower than the outer diameter of the single crystal.
CONSTITUTION: A seed crystal 4 is brought into contact with the melt of starting materials for single crystal and the liquid selant 2 and pulled up to allow a single crystal 5 to grow at the center of the crucible. An X-rays generator 7a and an X-ray detector 9a are set oppositely in front and in rear of the crystal 5 so that the X-rays 9a from the generator 7a may pass through the center of the crucible 3 and the side wall opposing to it. Thus, the distance between the side of the single crystal 5 and the opposing side wall of the crucible is measured with a roentogenographic picture of the single crystal 5. The value is subtracted from the radius of the crucible to detect the outer diameter of the single crystal 5.

摘要： PURPOSE: To calculate and determine the outer diameter of a crystal, easily, in small error, with a relatively low X-ray intensity, by irradiating a crystal with X-ray from the direction perpendicular to the pulling up axis, and measuring the thickness and the surface position of the liquid encapsulant before and after the pulling of the crystal.
CONSTITUTION: The molten liquid 3 of the crystal raw material encapsulated with the liquid encapsulant 2 in the crucible 4 heated with the heater 5, is irradiated with the X-ray generated from the X-ray generator 6 placed outside of the heater 5 perpendicular to the pulling up axis. The thickness (t, t') of the encapsulant and the distance (l, l') between the bottom of the crucible 4 and the surface of the encapsulant are determined from the image of the transmitted X-ray detected by the X-ray image detector 7 when the lower end of the seed crystal is brought into contact with the upper surface of the molten crystal raw material liquid, and when the seed crystal is pulled up and the grown crystal is emerged from the surface of the encapsulant 2 following the seed crystal 1. The outer diameter of the crystal can be calculated from the variation of the above values.

摘要： PURPOSE:To obtain a smooth inclined end surface by applying flaws at a position where bending stress of an optical fiber was produced. CONSTITUTION:By supporting an optical fiber 1 with a pair of clamps 2a, 2b, tensile stress and torque are given, and by bending the central part along a convex surface of a jig 3, at this part bending stress is produced. When with this state a maximum part of bending stress is pressurized with a diamond cutter 4, etc., and the part is scraped, stress rupture is produced and a smooth inclined end surface is obtained. An inclination angle at the inclined end surface changes with torque and bending stress. If torque is not applied, an end surface perpendicular to the center of the optical fiber 1 is obtained.

摘要： PURPOSE: To obtain a single crystal having high purity and low dislocation and which is semiinsulating by exchanging a liq. sealant wherein impurities, etc., are mixed and melted in the preparation stage, etc., for a fresh liq. sealant when a single crystal is manufactured by the liq. sealant pulling method.
CONSTITUTION: A crucible 2 is arranged in a high-pressure vessel 1, and a raw material 3 and a liq. sealant 4 are charged into the crucible 2. The crucible 3 is heated in the high-pressure atmosphere by a heater 5 to melt the raw material 3 and the liq. sealant 4. Since impurities, etc. may be mixed into the materials in the preparation and arrangement stages, the molten liq. sealant 4 is sucked up into a recovery vessel 6 by utilizing the pressure difference and recovered. Then a liq. sealant 24 in a filled vessel 7 is pushed out from a filling port 17 by the pressure of the high-pressure gas, and charged onto the raw material melt 3 in the crucible 2. After a specified time, seeding is carried out by a seed crystal 15 attached to the leading end of a lifting shaft 13 and a single crystal is pulled up.
