    摘要： It is an object of the invention to relax magnetic saturation and realize a high-performance magnetic shield effect that is suitable for magnetic devices such as an MRAM. A magnetic shield member of the invention is suitable for a magnetic memory device in which a magnetic random access memory (MRAM) consisting of a TMR element formed by stacking a magnetization fixed layer with a direction of magnetization fixed and a magnetic layer, in which a direction of magnetization can be changed, via a tunnel barrier layer is sealed by a sealing material such as resin. A planar shape or a sectional shape of magnetic shield plates provided on the sealing material in order to magnetically shield the MRAM is a shape in which a side substantially perpendicular to a direction of an outer magnetic field and a side substantially parallel to the direction of an outer magnetic field are not orthogonal to each other, in particular, circular, polygonal, or the like, whereby it is possible to relax magnetic saturation of the magnetic shield plate and keep the magnetic shield effect.

    摘要： In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glass 14 is broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.

    摘要： There is disclosed a thinner-layered radio wave absorber having high absorption performance for a high frequency electromagnetic wave. The radio wave absorber, even when having a magnetic layer of not more than 1 mm in thickness, achieves satisfactory absorption characteristics for the high frequency electromagnetic wave by adopting a structure that a conductor is fixedly attached to a face opposite to an electromagnetic-wave incident face of the magnetic layer of single-layered structure, and also arranging the magnetic layer to have values of a real part &mgr;′ and an imaginary part &mgr;″ of complex relative magnetic permeability of the magnetic layer satisfying an expression of &mgr;″≧m&mgr;′−n (m: real number of m>0, n: real number of n≧0) outside an impedance mismatching region.
