Title:
DAMPING PLATE
Document Type and Number:
WIPO Patent Application WO/2000/005518
Kind Code:
A1
Abstract:
A damping plate capable of suppressing a production cost to a low level and eliminating a dislocation from occurring on a substrate starting with a cracking even if an external force is applied to it from a side direction, wherein a linear bead part (24) is formed at a specified part of a metal plate (10) so as to provide a damping effect to the metal plate (10) by a cracking (26) caused in the bead part (24) and, in the steel plate (10) large in hardening capability, a linear hardened part (28) is formed at a specified part of the steel plate (10) so as to provide a damping effect to the steel plate (10) by a cracking (30) caused in the hardened part (28).
