摘要： A lubricant composition comprising from 0.1 to 10% by weight of a phosphate glass, characterized in that said phosphate glass comprises from 45 to 75 mole % of P.sub.2 O.sub.5, from 10 to 35 mole % of M.sub.2 O (M represents alkaline metals) and from 0 to 45 mole % of B.sub.2 O.sub.3. Phosphate glasses are in the form of powder with white to ash-colored appearance, and do not cause dirt of working surroundings. Phosphate glasses are less expensive than solid lubricants which are conventionally used, and also excellent load carrying capacity can be attained by adding a small amount of phosphate glass to a lubricant composition. Accordingly, the lubricant composition of the present invention shows better load carrying capacity than a conventional lubricant composition.

摘要： An inspection device (1) includes a light source (10) projecting excitation light to an inner surface of a container (20); an imager (11) capturing a fluorescence image of fluorescence emitted from a foreign substance in response to the excitation light projected; and a detector (13) detecting the foreign substance adhering to the inner surface of the container from the fluorescence image captured by the imager. The foreign substance contains a material emitting fluorescence in response to the excitation light projected to the material. The detector includes a calculator (14) calculating an average brightness value in an inspection target region, and an adjuster (15) adjusting an image-capturing condition where the fluorescence image is captured such that the average brightness value falls within a preset range.
