Title:
マイクロカプセルの壁膜の厚み算出装置
Document Type and Number:
Japanese Patent JP4115313
Kind Code:
B2
Abstract:
A thickness-determining apparatus for determining a wall thickness of a microcapsule having a refractive index n 1 comprises a sensor 1 for detecting a light scattering intensity data I 1 with respect to the microcapsule dispersed in a medium having a refractive index n 1 , and a light scattering intensity data I 2 with respect to the microcapsule dispersed in a medium having a refractive index n 2 ; a memory circuit 3 for storing a theoretical equation correlating a light scattering intensity characteristic with a particle size; and an arithmetic circuit 5 for calculating an inner diameter r 1 and an outer diameter r 2 from the theoretical equation based on the light scattering intensity data I 1 and I 2 , and calculating the wall thickness.
