Title:
The spreading analysis device of a lubricant, a method, a program, a recording medium
Document Type and Number:
Japanese Patent JP6161867
Kind Code:
B2
Abstract:
According to the present invention, a device for analyzing a spread state of a lubricant (1) in a device under test in which particles constructing a tablet and the lubricant are mixed with each other, includes: an electromagnetic wave output device; an optical element (14); an electromagnetic wave detector (10); a spectrum deriving unit; and a characteristic extraction unit. An electromagnetic wave output device (12) outputs an electromagnetic wave. An optical element has a total reflection surface for totally reflecting the electromagnetic wave, and causes the device under test to receive an evanescent wave generated from the total reflection surface. An electromagnetic wave detector detects the electromagnetic wave totally reflected by the total reflection surface. A spectrum deriving unit derives a reflectance of the electromagnetic wave on the total reflection surface or a value based on the reflectance based on a detection result by the electromagnetic wave detector while the reflectance or the value based on the reflectance is associated with the frequency of the electromagnetic wave and a manufacturing condition of the particle or the device under test. A characteristic extraction unit (20g) extracts a characteristic based on the manufacturing condition from a derived result by the spectrum deriving unit.
