Title:
SHIELD MEMBER
Document Type and Number:
Japanese Patent JPH1126981
Kind Code:
A
Abstract:

To improve shielding property for a magnetic or electric gap, by partially overlapping end parts of a plurality of strip-shaped magnetic thin belts composed of amorphous alloy or nanocrystal alloy, arranging them in parallel and integrating them in an unified body with resin.

Amorphous thin belts are formed by using a liquid quenching method like a single roll method. After that, microcrystallization is performed by a thermal treatment at a temperature higher than or equal to the crystallization temperature, and nanocrystal material ribbons are obtained. The end parts are so partially overlapped that the ribbons as magnetic thin belts of amorphous alloy or nanocrystal alloy which are obtained in the above processes can be magnetically and electrically combined. The partially overlapped ribbons are arranged in a plurality of parallel rows, and sheets made of resin are bonded on the whole of both sides. Thereby shielding property of amorphous and nanocrystal material can be sufficiently exhibited.
