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.

Abstract: A closure assembly for preventing transmission of interference fields, especially high-frequency magnetic fields. The assembly comprises a closure which is disposed to be movable with respect to a fixed structure, with the closure and/or the fixed structure being provided with elements for establishing contact and thereby preventing transmission of interference fields between the two. In accordance with the present invention, the closure is disposed to move substantially rectilinearly in a direction substantially perpendicular to a plane along a surface of the closure, and substantially rectilinearly in a direction substantially parallel to the plane of the closure.

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. When the member is threaded into an open, unlocked position, the locking of the second structure is released vis-a-vis the first structure, whereby the inner room is allowed to vibrate, irrespective of the vibration of the other shield structures, and hence, the potential vibration of the room is not transmitted to the shielding structures.

Abstract: A shield wall structure for a magnetically-shielded room and a method for producing a magnetically-shielded room in which the shield wall structure includes at least one shield structure layer, each shield structure layer having a first aluminum sheet layer, a two-ply layer of .mu. metal sheets, and a second layer of aluminum base sheets. In the aluminum sheet constituting the first layer, holes are made at a hole spacing equivalent to the width of the .mu. metal sheets. Support members are disposed in the holes. The first layer of .mu. metal sheets is suspended, supported on the support members, and on top of these, the second layer of .mu. metal sheets is suspended by the support members in another direction. On top of the two-ply .mu. metal sheet structure, the base sheets of aluminum are positioned in conjunction with the support members. Tightening members are then coupled to the support members for operatively compressing the entire wall structure into a compact package.

Abstract: A door assembly in a construction for preventing the transition of interference fields, in particular of high-frequency electromagnetic fields, into a space, wherein the contact zone between the door and a stationary structure is sealed by a labyrinth construction which attenuates the transition of interference fields. In prior art constructions, the provision of such labyrinth constructions increases the difficulty of door operation as a result of the high compression force which is required for closing the door as well as the tendency of the pivoting movement of the door to damage the labyrinth construction. In order to overcome this problem, apparatus are provided such that the movement of the door comprises the usual pivoting movement thereof with respect to an axis and, additionally, a substantially linear controlled final path of movement during which a contact preventing the transition of interference fields is produced.
