Abstract: PURPOSE: To determine easily and accurately the surface density of a material such as atoms and pigment by measuring photographic density through an X-ray film, by irradiating a thin plate, original paper applied with pigment, etc., including metal atoms, with X-rays produced by two fixed selected bulb voltages.  
     CONSTITUTION: On original paper 5a such as paper and a plastic film, pigment 5b such as calcium carbonate is applied, charged or laminated to form thin plate 5. This thin plate 5 is irradiated with X-rays by selecting X-ray bulb voltage greater and less than the maximum value of mass absorption coefficient μ b  of calcium carbonate, thereby measuring through X-ray film 5 the photographic density by transmitted X-rays. Next, the condition, μ a1 μ b2 -μ b1 μ a2 ≠0, is satisfied on the basis of equation I to determine accurately surface density values W a  and W b  of the original paper and calcium carbonate. Further, when the photographic density is measured by irradiating atoms and pigment independently with X-rays by bulb voltages nearly equal in absorption coeffcient, the surface density of the thin plate of them is determined. Here, I 1 , I 01 , I 2  and I 02  represent actually-measured absorbance.

Abstract: PURPOSE:To improve working environment and the quality of cut surfaces in the stage of cutting a thin sheet by using gaseous Ar+N2 plasma with a hand type small-sized plasma torch of a water shielding system, by specifying the distance between an electrode and a nozzle. CONSTITUTION:A plasma torch body 1a supplies gaseous Ar upon starting, and joins gaseous N2 with the gaseous Ar and supplies the mixture as gaseous plasma 7 at the same instant when plasma 2 is generated. When the cutting of a thin sheet 5 is started by supplying water 16 to the outside circumference of a nozzle tip 12 at the same instant as the above, the generation of harmful gases together with the nitriding and oxidation of the cut surfaces can be prevented by the sealing effect of the water 16.

The thin sheet is thus cut satisfactorily so as to have the sharp cut surfaces with small shoulder droops and with virtually no dross stuck thereon.
