Title: Plasma fusion experimentation apparatus
Inventor: YAMAGUCHI SAKUTARO
IPC: G21B1/11
Filed: 1989-05-24
Abstract: PURPOSE:To control effectively a large current flowing through plasma by conducting controls of removal, amplification, attenuation, etc. with respect to an induction field induced in the direction of the torus great circle of a torus-shaped vessel due to a change in a current of an external coil or others. CONSTITUTION:Confinement of plasma changes with a change incoordination of a helical magnetic field. On the occasion, the intensity and direction of an induction field or the amplitude and polarity of a plasma current and detected and, based on detection signals obtained thereby, a current having an amplitude and polarity enabling removal of the induction field is made to flow through a coil 12 for field control. An induced electromotive force in the direction reverse to that of the induction field is generated in a helical coil 6 by magnetic coupling. Thereby the induction field is removed and a large current flowing through the plasma is suppressed.

Filed: 1990-05-22
Abstract: PURPOSE:To measure the performance index of a magneto-optical disk with high accuracy by forming patterns for measurement not only on an information recording band but also on the both side guard band so that the magnetizing direction can be made same. CONSTITUTION:On a magneto-optical disk 1, an information recording band 6 and guard bands 7 are spirally or concentrically provided. The patterns for measurement are formed so that the magnetizing directions of the information recording band 6 and the both side guard bands 7 can be changed at constant intervals. In an area A voided in the figure, the magnetizing direction is downward and in an area B shown by hatched lines, the magnetizing direction is upward. In this way, the patterns for measurement are recorded to the information recording band 6 and the guard bands 7 so that the magnetizing direction can be alternately inverted along the lengthwise direction at constant intervals. Thus, the performance index can be measured highly accurately without being affected by the forming condition of the pattern or the like.
