  • Patent number: 5736671
    Abstract: A door structure for a magnetically-shielded room intended to absorb interference magnetic fields, particularly very low frequency magnetic fields, and arranged to move substantially rectilinearly in the direction of the plane of the door leaf, and substantially rectilinearly in a direction which is perpendicular to the plane of the door leaf. The door leaf is attached to a support structure of the door leaf by hinge mechanisms so that the door leaf is movable perpendicular to the structure of the door leaf in order to provide a movement in a direction perpendicular to the plane of the door leaf. The door structure includes power transmission members arranged to exert an effect on press members on the edge areas of the door leaf such that the press members turn around hinging members whereby exposed .mu. metal sheet structure on the edge areas of the door leaf is pressed tightly against .mu. metal sheet structure of the shielding wall structure at an aperture in a wall of the magnetically-shielded room.

  • Patent number: 5613330
    Abstract: A support pillar system for a magnetically-shielded room including several support pillars, each support pillar including a nested structure formed by a first structure and a second structure surrounding the first structure. The upper end of the first structure has a threaded part and a member provided with a thread and disposed about the threaded part. The shielding structure of the magnetically-shielded room is attached to the second structure of the support pillar, whereby the floor of the room is supported on the upper end of the first structure. When the member provided with a thread is tightened in a locking position, it locks the first structure and the second structure together, whereby the vibration of the floor is transmitted to the shielding structure and the shield vibrates substantially in synchronization with the vibration of the floor of the room.
