Description
【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明はシート状の磁気じゃへい材に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a sheet-shaped magnetic barrier material.
（従来の技術） 従来の磁気じゃへいは、鉄等の強磁性体を用い。(Conventional technology) Conventional magnetic jaws use ferromagnetic materials such as iron.
第３図に示すような箱１で行なっていた。強磁性体の磁
界を吸い寄せる効果により、箱の内部を外部磁界からし
やへいしたい場合、及び箱の外部への箱の内部磁界のも
れを少なくしたい場合に箱は有効であった。This was done in Box 1 as shown in Figure 3. Due to the magnetic field attracting effect of the ferromagnetic material, the box is effective when it is desired to shield the inside of the box from external magnetic fields and when it is desired to reduce leakage of the internal magnetic field of the box to the outside of the box.
（発明が解決しようとする問題点）
しかし従来の強磁性体製の箱の場合、以下の問題点が存
在した。(Problems to be Solved by the Invention) However, in the case of conventional boxes made of ferromagnetic material, the following problems existed.
ω 強磁性体には、磁界の強い方向への磁気力が働くた
め、この力が問題となる箇所への適用は困難であった。ω Since magnetic force acts on ferromagnetic materials in the direction of the strong magnetic field, it has been difficult to apply this method to locations where this force is a problem.
■ 強磁性体は非線形の磁化特性をもつため、磁気しや
へい効果が磁界強度に依存した。■ Because ferromagnetic materials have nonlinear magnetization characteristics, the magnetic flux effect depends on the magnetic field strength.
（問題点を解決するための手段）
本発明の磁気じゃへいシートは酸化物超電導体の微粒子
をシート状の基材に埋め込んだ構成とする。(Means for Solving the Problems) The magnetic barrier sheet of the present invention has a structure in which fine particles of an oxide superconductor are embedded in a sheet-like base material.
（作用）
酸化物超電導体は、磁界を完全にはじき出す効果があり
磁界をしゃへいする。そのため本発明の磁気じゃへいシ
ートでは、磁気じゃへい効果が磁界強度に依存しない。(Function) Oxide superconductors have the effect of completely repelling magnetic fields and shield them. Therefore, in the magnetic barrier sheet of the present invention, the magnetic barrier effect does not depend on the magnetic field strength.
又、酸化物超電導体は微粒子としての製造は容易であり
、これを有機化合物中に埋め込みシート状とする事も容
易である。In addition, oxide superconductors can be easily produced in the form of fine particles, and can also be easily formed into a sheet by embedding them in an organic compound.
（実施例） 以下第１，２図に基づいて実施例を説明する。(Example) An embodiment will be described below based on FIGS. 1 and 2.
第１図は、本発明により磁気じゃへいシートの断面図で

る。第２図は、この磁気じゃへいシートを用いて作った
磁気カードケース４である。FIG. 1 is a cross-sectional view of a magnetic barrier sheet according to the present invention, in which 2 is an oxide superconductor particle and 3 is an organic compound. FIG. 2 shows a magnetic card case 4 made using this magnetic jacket sheet.
第２図の例に限らず、あらゆる分野の磁気じゃへいに本
発明を適用できる。The present invention is applicable not only to the example shown in FIG. 2 but also to magnetic devices in all fields.
本発明を実施する事により、完全な磁気じゃへいが可能
になる他、従来、しやへい材に働く吸引磁気力が問題で
あった分野にも使用可能となる。By carrying out the present invention, complete magnetic repellency becomes possible, and it can also be used in fields where the attractive magnetic force acting on refractory materials has conventionally been a problem.
又、しやへいシートとしての製造方法が簡便であり、任
意の形状のしゃへい体を構成できると言う利点もある。Further, there is an advantage that the manufacturing method for the shield sheet is simple and that a shield body of any shape can be constructed.
