Title: Production of single crystal of compound semiconductor
Inventor: USHIZAWA JISABUROU
IPC: C30B27/02
Filed: 1983-03-30
Abstract: PURPOSE:In the liquid encapsulating method, the temperature gradient near the solid-liquid inter face in the starting melt for compound semiconductor is set higher outward in the radial direction in a certain temperature range to produce single crystals which causes no B-Pit and have less transition density of the wafer and less residual stress. CONSTITUTION:In the liquid encapsulating method, the starting materials for GaP crystals and B2O3 as a liquid encapsulating agent are melted in the quartz crucible 2 inside the pressure vessel 1 by heating with the carbon heater 3 to cover the surface of the GaP melt 4 with the B2O3 layer 5. The vessel has been previously filled with N2 gas by vacuum replacement and is pressurized, as the temperature is raised up, to avoid GaP from decomposing and vaporizing. Then, the seed crystal 6 is pulled up, as being rotated to form the GaP single crystal 7. At this time, the temperature gradient near the solid-liquid interface in the melt 4 is set higher outward in the radial direction in the range from 4 to 30 deg.C/cm within the zone of at least crossing the outer periphery 15 of the pulled-up crystal 13.

IPC: B21J5/06
Filed: 1987-03-10
Abstract: PURPOSE:To better the uniformity of a metal structure by preventing an inner part crack by inclining the rolling reduction face of die at specific angle in the case of reducing the diameter of the material to be forged in an axial shape by subjecting to a rolling reduction by a die. CONSTITUTION:A forging is effected by die by arranging at equal intervals in the four directions of orthogonal direction for the axial direction of the material 1 to be forged. In this case those which have the rolling reduction face inclining at an angle delta (2 deg..7 deg.) for the vertical face in the rolling reduction direction of the anvil are used. Dies 2a-2d are moved in the centripetal direction simultaneously from the orthogonal four directions for the axial direction of the material 1 to be forged to subject the material 1 to be forged to rolling reduction. Then the dies 2a-2d are simultaneously pulled in to rotate the material 1 to be forged in an arrow mark A direction and the dies 2a-2d are again moved in the centripetal direction simultaneously from the four parts in the orthogonal direction for the axial direction to effect rolling reduction. By repeating this the axial cogged roll stock having uniform metal structure is obtd.

Title: Method of injection-molding extremely high molecular weight polyethylene
Inventor: YOKOTA AKIRA
IPC: B29C45/23
Filed: 1990-03-05
Abstract: PURPOSE:To prevent the interlayer separation of a molding by injecting molten polyethylene into a die cavity at high pressure and for a short time after the plastic measurement, and then molding it in a highly pressurized state. CONSTITUTION:In concurrence with the injection commencement, the rotary valve 4 is opened and the screw 2 is forwarded at an injection speed of previously set value.

At this screw advanced position, resin within the cavity 7 of a die 6 is filled at a pressure of 1000kg/cm<2> or higher. After the injection commencement, the movement of the screw 2 is detected by a screw position detector 11 wherein the value set by a setter 12 and the detected value detected by a position detector 1 are compared by a comparator 13 and, when both values come to be equal, the injection speed control device 20 is commanded to receive the order to stop the injection and the driving device 18 is also commanded to receive the order to close the valve 4, and they are kept during the period of solidifying resin by injection pressure. Whereby, a molding having no interlayer separation and with highly dimensional accuracy can be obtained readily.
