LOW LEAKAGE SHAKING OPEN TYPE MAGNETIC SHIELD STRUCTURE
PROBLEM TO BE SOLVED: To provide a low leakage shaking open type magnetic shield structure capable suppressing leakage of shaking noise small.SOLUTION: On multiple stages of parallel planes Pz1, Pz2, ... crossing a first direction axis Az penetrating a magnetic shield object space 1 at predetermined intervals dz, annular band-like magnetic plates 10 are provided in such a manner that the object space 1 is surrounded with a predetermined band width W. In multiple portions that are distributed in an annular axial direction, on each of the stages of the annular band-like magnetic plates 10, a lead wire coil unit 20 is wound and fitted in a direction that is substantially perpendicular to the annular axis, and both ends 22a and 22b of the lead wire coil unit are pulled out adjacently in parallel. The annular band-like magnetic plate 10 is magnetically shaken by a magnetic field that is generated by applying a shaking current I1 in a predetermined frequency in parallel to the pulled-out portions 22a and 22b of each lead wire coil unit 20 by a coil drive device 30. Preferably, both the ends 22a and 22b of each of the lead wire coil units 20 are pulled out while being twisted mutually.SELECTED DRAWING: Figure 1
【課題】シェイキングノイズの漏洩を小さく抑えることができる低漏洩シェイキング式開放型磁気シールド構造を提供する。【解決手段】磁気シールド対象空間１を貫く第１方向軸Ａｚと所定間隔ｄｚで交差する複数段の平行な平面Ｐｚ１，Ｐｚ２，……上にそれぞれ対象空間１を所定帯幅Ｗで囲むように環帯状磁性板１０を設け，環帯状磁性板１０の各段の環状軸方向に分散した複数部位にそれぞれ環状軸と実質上直角向きに導線コイルユニット２０を巻き付けて取り付け且つその両端２２ａ，２２ｂを平行に隣接させて引き出し，コイル駆動装置３０により各導線コイルユニット２０の引き出し部２２ａ，２２ｂに所定周波数のシェイキング電流Ｉ１を並列に印加して発生させた磁場により環帯状磁性板１０を磁気シェイキングする。好ましくは，各導線コイルユニット２０の両端２２ａ，２２ｂを相互に撚りながら引き出す。【選択図】 図１
