Title:
MEASURING APPARATUS FOR ELECTRIFICATION AMOUNT
Document Type and Number:
Japanese Patent JP3560400
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which the saturation electrification amount and the saturation time of a sheetlike or filmlike sample are measured efficiently without hardly damaging the sample to be measured.
SOLUTION: A measuring apparatus is composed of a sample plate 3 in which a sample layer 2 is formed so as to come into contact on a conductive substrate 1, of a sample-plate holding member 4 which holds the sample plate 3, of a roller 5 which is installed so as to come into contact with the sample plate 2, of a sample-plate movement mechanism 6 which moves the sample-plate holding member to a direction perpendicular to the tangent line of the roller 5 to the sample layer 2 and of an electric-charge measuring device 7 which measures the electric charge amount of the sample plate 3. The sample plate 3 is moved back and forth by the sample-plate movement mechanism 6, it is repeatedly brought into contact with, and separated from, the roller 5, and an electric charge which is generated in the sample layer 2 is measured by the electric-charge measuring device 7.
