Abstract

PURPOSE:To raise the magnetic permeability and electric conductivity, as well as to improve the anticorrosion properties and to make resistance against the mechanical bending and strain by mainly consisting a magnetic shielding spring of Fe, Co, Ni, and B. CONSTITUTION:The periphery of a door 31 is coated with magnetic shielding material 311, the surface of the pillars 32,33 of the frame body, on which the door 31 of a magnetic shield room is to be attached, is coated with magnetic shielding material 34 continuing from the wall body surface. For filling the air gap between the door 31 and the frame, a magnetic shielding spring 20 is attached at both ends of the door 31. The attaching work is done by screwing the screws by the screw holes in the door 31. The magnetic shielding spring consists mainly of Fe, Co, Ni, Si, and B and is consisting of noncrystalline metal rich in flexibility, anticorrosion and strongly resistant to the bending and mechanical strain.
