Abstract: PURPOSE:To rapidly and accurately make qualitative and quantitative analysis of respective constituting materials in a mixture by condensing laser light through the light transparent window on the side face of a development cell to the surface of a development medium, then condensing, spectrally dividing and detecting the Raman light scattered on this medium. CONSTITUTION:The lower part of the development medium 2 spotted and loaded with a mixture sample 1 as a sample for analysis is immersed into the developing liquid 4 stored in the bottom of the development cell 3 which is hermetically closed by a cap 5; in addition, the medium 2 is so erected and installed as not to immerse the sample 1. The liquid 4 gradually rise in the medium 2 in the cell 3 by capillarity. The respective component materials constituting the sample 1 rise respectively at different speeds as the sample rises. These materials are thereby separated from each other. The respective materials are irradiated with the laser light 9 which is generated by a laser generator 6, is condensed 7 and is passed through a thin-plate glass window 8. The irradiation is executed in the order of the higher development speeds. The Raman scattered light rays 10 generated respectively from the respective materials are spectrally divided 11 and detected 12 through the window 8. The detection signals are subjected to data processing 13 by a computer and are outputted by a CRT monitor 14 or recorder 15.

Filed: 1990-02-13
Abstract: PURPOSE:To remove dirt from a gap of cement for seaming a groove between tiles and a gap between a floor and threshold by forming a lump with over heat and press on an end of a synthetic resin bristle. CONSTITUTION:A lump 2 is formed on an end of a bristle 1 by using synthetic resin for fiber portions of a cleaning implement such as brush and broom and pressing the end of the bristle while overheating it.
