Title: Adjustment method for x-ray optical system
Inventor: SUZUKI SHINJI
IPC: G01N23/00
Filed: 1992-07-02
Abstract: PURPOSE:To enable highly accurate adjustment satisfying the adjustment condition of an optical system to be made by setting a laser beam perpendicularly to the target of an X-ray source across an X-ray focal point position, and adjusting the optical system using the beam as an optical axis. CONSTITUTION:A laser beam perpendicular to the target of an X-ray source 1 is set, using a half mirror 3. A mirror is first attached to an optical part requiring perpendicular alignment, for example, a fluorescent screen holder. Then, the half mirror 3 is observed with an observation camera 4, and a laser beam travelling toward a fluorescent screen 5 through the half mirror 3 is detected as emitted from the position P1 of the mirror 3. Furthermore, it is observed that this laser beam has arrived at the position P2 of the mirror 3 after reflection on the attached mirror. Then, the inclination of the fluorescent screen holder in both horizontal and vertical directions is so adjusted so as to keep the positions P1 and P2 superposed on top of each other. According to this construction, the perpendicularity of the fluorescent screen 5 can be accurately maintained.

Title: Magneto-optical recording medium
Inventor: TANAKA HIROTAKA
IPC: G11B11/10
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of the film over the entire part of a magnetic layer having an axis of easy magnetization in an intra-surface direction and to improve C/N by disposing a nonmagnetic layer or the magnetic layer between a reproducing layer (R layer) having perpendicular magnetic anisotropy and a recording layer (M layer) and transferring magnetization by magnetostatic bonding without an exchange bonding of the R layer and the M layer. SOLUTION: The nonmagnetic cut layer 4a having a film thickness of 1 to 30Å is disposed between the R layer 3 and the M layer 4. (The cut layer having the axis of easy magnetization in the intra-surface direction is otherwise disposed in all the operating temp. range). As a result, the exchange bonding strength between the R layer 3 and the M layer 4 is controlled to the desired value and the magnetization direction is transferred to the R layer 3 with the static magnetic bonding by the leak magnetic fluxes of the M layer 4. A recording assisting layer (W layer) 6 is merely necessitated to transfer the magnetization direction by the exchange bonding only to the M layer 4 and therefore, the reduction of the film thickness of the W layer 6 is made possible and further the reduction of the film thickness of an initialization layer 8 is made possible, by which the thickness over the entire part of the magnetic layer is reduced. The thermal conductivity and heat radiatability are improved by the reduction in the film thickness, the sensitivity of information recording and erasing is improved and the stable execution of overwriting is made possible.

Moreover, the number of the notches along the spool shaft direction is reduced, and the valve can be miniaturized and lightened.
