Abstract: PURPOSE:To obtain a single crystal production device capable of efficiently transferring heat to the central part of a crucible, by setting a heater to heat and to melt raw aqueous melt in the crucible below the bottom of the crucible and laying an electric current circuit for magnetic field application, having an circuit part in parallel with the central axis direction of a furnace, at the side of the crystal pulling up furnace. CONSTITUTION:A heater 25 is set below the bottom of a crucible 24 and single crystal 26 is pulled up from raw material melt 23 while feeding a raw material 30. In the pulling up, a rod of the raw material 30 (Si polycrystal) is melted from the top of the crucible 24 by high-frequency induction heating and continuously fed to the crucible 24. Then, Si is fed to the crucible 24, the heater 25 set below the crucible is heated by sending electric current and the single crystal 26 is pulled up while heating and keeping the melt 23 warm. Further an electric current is sent to an electric current circuit 31 for magnetic field application laid in the periphery of a furnace 21 and magnetic field in the horizontal direction is impressed to the melt 23. Consequently, agitating flow by heat convection in the melt 23 is suppressed and Si single crystal having extremely excellent quality, drastically reduced formation of defect and very slight degree of impurity segregation is obtained.

Title: Optical disk driver
Inventor: SHIMODA KYOJI
IPC: G11B7/085
Filed: 1988-12-05
Abstract: PURPOSE:To surely control the actuation of focusing servo with an simple constitution by detecting the pulling-in of the focusing servo from the number of track crossing times of a tracking error signal caused by the eccentricity of an optical disk medium. CONSTITUTION:At the time when pulling-in of focusing servo is started, a comparator 13 makes level discrimination after a drive control circuit 14 commands a focusing initializing signal generator 7 to send a tracking initializing signal A and an actuator is driven. Then, when it is discriminated by the comparator 13 that the focusing servo almost completes, the circuit 14 causes the generator 7 to stop the sending of the signal A and a focusing servo loop is closed. When the focusing servo operations are started thereafter, a tracking error signal detector 5 outputs a signal D and the signal D is inputted to a comparator 9 by means of which the number of track crossing times is detected. The number of track crossing time is discriminated by means of a counter 15 and, when the number exceeds a specific value, the actuation of the focusing servo is completed. Therefore, focusing servo can be actuated surely with a simple constitution.
