Title:
ASSESSMENT OF SUITABILITY OF INTERNAL PRESSURE OF CANNING CANS
Document Type and Number:
Japanese Patent JPS5273783
Kind Code:
A
Abstract:
PURPOSE: To assess whether the internal pressure of canning cans is good or not by decomposing acoustic waves generated through application of external force to the cover of a canning can to simple harmonic motirion, deriving the sound pressure of specific frequency according to the shape of the can to be measured and comparing the indicated value of the acoustic pressure difference with a reference value.
