Abstract: PURPOSE:To produce a single crystal which has fewer lattice defects and maintains a lattice constant by adding impurity atoms which are liable to be magnetized to the melt of the single crystal raw material in a crucible and enclosing the outside peripheral face of the side wall of the crucible with a magnet at the time of pulling up the single crystal from the above-mentioned melt. CONSTITUTION:The single crystal material 2 in the crucible 3 is melted by a high-frequency heater 1 enclosing the outside peripheral face of the crucible 3 and the outside peripheral face of the heater 1 is enclosed by the magnet 6. The impurity atoms 4 which are liable to be magnetized are added to the single crystal material 2 heated to the melt state and a seed crystal 5 is used. the single crystal is pulled up while the crucible 3 or the seed crystal is kept slowly rotated. The impurity atoms 4 which are liable to be magnetized are attracted by the magnet 6 and are gathered near the wall of the crucible. The generation of the dislocation from the surface of an ingot is thereby suppressed with the smaller concn. of the impurity atoms than heretofore; in addition, the microdefects in a water and the ununiformity of the lattice constant arising from the added impurity atoms 4 are suppressed.

Abstract: PURPOSE:To control a data driving type processing operation even to a computer system having common data by giving a time attribute to each data in an information processing system and regarding data at a different time as different data. CONSTITUTION:In a data time attribute 6, a time attribute indicating a time completing the generation of the data for every data is held and in a processing time attribute 8, the time attribute of a process subjected to the generation of a wake-up request next for every work is held. Moreover, when an access complete report is sent from a computer system 1 to a control mechanism 2, the data time attribute of process are also sent together with the report to identify the completed processes. Namely, the process time attribute 8 performs expression based on a prescribed numerical expression against a data group registered in a reference data table 7 and, when the numerical expression holds to all the data, the process time attribute 1 is increased by ''1'' after the process start-up request is generated. Therefore, data at the different time are regarded as different ones even when they are the same data and the process operation can be controlled under a data driving mode.
