Abstract: PURPOSE:To improve production efficiency and permit mass production by installing a plurality of grindstones concentrically and making the peripheral speed of the grindstone nearly equal and carrying-out polishing by setting the articles to be polished in multistages in the radial direction of the revolving grindstone. CONSTITUTION:An article 8 to be polished is freely fitted into holding bodies 33 and 34, and a holding mechanism 32 is lowered by an elevation mechanism, and the article to be polished is pressed onto grindstones 5 and 6. A power shaft 13 is revolved in the direction of arrow 38 b driving a motor 12. Then, an outside polishing article 24 revolves in the direction of arrow 39 through spur gears 14 20, and 21, while, an inside polishing article 25 revolves in the direction of arrow 39 through spur gears 15, 22, and 23. The polished article 8 rotated following to the revolution of the polishing articles 24 and 25. Therefore, the polishing work for the polished article 8 is carried-out at a nearly equal speed, and the working completion time is made equal between two polished articles 8. Since there is no difference between the working speed for the polishing articles 24 and 25, the polished articles 8 can be set in the radial direction in two stages, and production efficiency can be improved.

Abstract: PURPOSE:To produce a refractive index-distribution lens having the action of concave lens, by contacting a glass filament or rod with a molten salt mixture consisting of TlNO3 and KNO3 at a specific ratio, thereby mutually diffusing and exchanging Tl cation in the molten salt with the cation in the glass. CONSTITUTION:A glass filament or rod composed of SiO2 and containing Na2O is made to contact with a molten salt mixture containing nitric acid salts such as TlNO3 and KNO3 at a molar ratio of 1:12 and TlNO3 concentration of 3-20mol% and kept in the contacting state at 500 deg.C for a long period. The Tl cation in the molten salt and the Na cation in the glass are mutually exchanged at the surface of the glass and the Tl ion is diffused and migrated into the glass from its surface. The lens produced by this process has Tl ion concentration increasing from the core toward the surface and has higher refractive index at the outer circumference than at the core to form a refractive index distribution to give a diverging light-transmission material having the action of convex lens.

Abstract: PURPOSE:To detect the choking of a sampling probe by detecting the length of an air layer to be sucked to a sample holding flow route for dilution prevention by an optical detecting apparatus installed in the middle of the sample holding flow route. CONSTITUTION:A semiconductive photodetecting element 2 is installed in the middle of a sample holding flow route 4 which joins a sampling probe 3 and a measuring syringe 5. An optical detecting apparatus is composed of a light source 1 and a detecting element 2.
