摘要： The present invention provides an optical disk control device that can perform focus pulling in a short time for a target information surface of an optical disk having a plurality of information surfaces. An objective lens (23) is moved toward an optical disk (1) having a plurality of information surfaces (1A, 1B) by the output signal of a driving signal generating circuit (42B), passage of an initial focused focal position is detected by a focal point passage detecting circuit (44), and when the objective lens moves past that position only a predetermined amount closer to the optical disk, an n-rotation delay circuit (70) outputs a reversal instruction f. After changing directions and moving the objective lens away from the optical disk, a focus pulling-in circuit (32B) switches a signal “a” that is output to an actuator driving circuit (21) from the output signal of the driving signal generating circuit to the output signal of the control circuit, activates a control circuit and performs focus pulling-in.

摘要： To find out a crystalline material for a high speed scintillator in place of BaF2 and the like, and a method for producing the material at a low cost. A single crystal of (Zn1−xMx)O1+x (M: Al, Ga, In, Y, Sc, La, Gd, Lu) (x=0 to 0.0500), (Zn1−xM′x)O1+2x(M′: Si, Ge, Sn, Pb)(x=0 to 0.0250) or (Zn1−xCdx)O (x=0 to 0.0500) is used as a scintillator. Defects of a ZnO single crystal can be reduced by using a platinum inner cylinder in order for a solution not to directly contact with an autoclave, for reducing impurities in the ZnO single crystal and precluding impurities interfering with scintillation, and by using LiOH and KOH as a mineralizer. ZnO can be doped with Al2O3, Ga2O3, In2O3, Si, Cd or the like by adding those materials to a starting material for the hydrothermal synthesis. The doping amounts can be controlled by changing charging amounts thereof. The doping of those elements inhibits the emission of visible lights, which results in the efficient transformation of the excitation energy to the luminescence from a free exciton.
