Abstract: The present invention relates to a non-therapeutic method, preferably a cosmetic method, of protecting keratin materials from pollutants, comprising: applying the keratin materials with at least one composition, preferably at least one cosmetic composition, comprising at least one particle having a wet point for oil being at least 100 ml/100 g, preferably at least 150 ml/100 g, and more preferably at least 200 ml/100 g, and a wet point for water being at least 100 ml/100 g, preferably at least 200 ml/100 g, and more preferably at least 300 ml/100 g. The present invention also relates to the use of the particle or the composition, and the like. The present invention can provide a method or process of protecting keratin materials from pollutants, as well as an anti-pollution agent and a use for the method or process.

Abstract: An optical fiber is held in a ferrule, and then the ferrule is located in a positioning groove formed in a substrate, thereby aligning the optical fiber with an optical device bonded to a surface of the substrate. Then, a lid is placed on the substrate in such a manner that the ferrule is located in a positioning groove formed in the lid and that the optical device is received in a cavity formed in the lid. The ferrule is thus held between the two grooves, and in this condition a resin is filled in the two grooves, thereby retaining the ferrule. Then, the lid is sealingly secured to the substrate. After these parts are thus assembled together, this assembly is put in dies, and then a package is molded.
