Inventor: OGINO HIROSHI
IPC: G01N1/22
Filed: 1989-11-24
Abstract: PURPOSE:To allow the accurate analysis of trace impurities by bringing the gaseous hydrogen sampled in a sample introducing part into contact with a hydrogen storage alloy to absorb away the gaseous hydrogen before introducing the gaseous hydrogen into a sepn. column 2 by a carrier gas. CONSTITUTION:The gaseous sample in a sampling pipe 8b is delivered by the carrier gas to a sample delivery conduit 7 and flows into a hydrogen removing column 11 where the gaseous hydrogen as the gaseous sample is absorbed by the hydrogen storage alloy in the column 11. The impurities, such as argon, nitrogen, oxygen and krypton, in the gaseous hydrogen as the gaseous sample are not absorbed and, therefore, only the gaseous impurities pass the column 11 and flow into the sepn. column 2. Since the hydrogen is absorbed away in the process before the inflow into the sepn. column 2 in such a manner, the peak of the hydrogen which is the essential component does not appear and as a result, the interference with the peaks of the other components does not arise at the time of analyzing the impurities in the gaseous hydrogen.

Title: Composite building material
Inventor: MATSUNO KICHIYA
IPC: E04C2/04
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To improve impact resistance and to prevent the design of a surface decorative layer of a composite building material, from being distorted even if the decorative layer is impacted, by allowing a core member constituting the composite building material having the decorative layer with a specific thickness formed at least on one surface thereof to contain an inorganic amorphous body internally having fibrous materials. SOLUTION: Decorative layers 5 each formed of a decorative veneer are arranged on both front and rear surfaces of a core member 1, and a reinforcing layer 6 is interposed between the core member 1 and each decorative layer 5 having a thickness of 0.1-10 mm, to thereby form a composite building material. The core member 1 contains an amorphous body 2 which internally contains organic fibrous materials 3 and inorganic fine particles 4, and the reinforcing layer 6 is constituted of a fibrous backing 6b impregnated with a resin 6a. The amorphous body 2 is an inorganic amorphous compound generated by solution treatment or hydration of two or more kinds of oxides, which compound serves as a strength manifestation material.  In addition, the fibrous materials 3 are dispersed in the amorphous body 2 to improve a fracture toughness value, leading to improved bending strength value and impact resistance. Therefore, even if an impact acts, a gouge is rarely formed, whereby the design of the decorative layer 5 is not distorted.

IPC: G01N23/20
Filed: 1989-11-30
Abstract: PURPOSE:To perform continuous measurement in a non-destructive manner while operation is carried out by evaluating the high-order processability of a plated steel plate on the basis of the evaluation value obtained from the X-ray diffraction intensities of a zeta phase and a gamma-phase and the X-ray diffraction intensities of the backgrounds of both of them. CONSTITUTION:When a zinc plated steel plate is subjected to alloying treatment, the thicknesses, that is, the quantities of the zeta-phase and gamma-phase among the zeta-phase, delta-phase and gamma-phase successively grown after a eta-phase disappears from the surface of the plated layer correspond to the magnitudes of the total X-ray diffraction intensities thereof. Based on this, the evaluation values [I(zeta)-IB(zeta)]/I(zeta), [I(gamma)-IB(gamma)]/I(gamma) calculated from the X-ray diffraction intensities I(zeta), IB(zeta), and I(gamma), IB(gamma) of the backgrounds of the respective zeta-phase and gamma-phase has good correlation with the quality of a product regardless of a plating adhe sion amounts. Therefore, high-order processability can be evaluated on the basis of these evaluation values measurable in a manufacturing line or even when separated from said line.
