摘要:
In a fluorescent X-ray analysis method, a sample (1) is set on a sample stage (2) on an upper side of an X-ray irradiation chamber (7) and a sample cover (6) is closed from the upper part of the sample (1) to surround the sample (1), and then, a lower plane of the sample (1) is irradiated with X-ray for analysis. When the sample (1) is set on the sample stage (2) and the sample cover (6) is closed, a cover detecting means (8) detects that the sample cover (6) is closed and X-ray is automatically projected from an X-ray source (3) to start analysis.

The concentration(s) of element(s) contained in an unknown sample is measured without necessity of judging the sample relying on a human's eye and obtaining information from a supplier of the sample previously. The concentration(s) of trace element(s) such as Cd, Pb and Hg contained in parts for electronic or electric equipment is determined by (1) irradiating the sample with an X-ray so as to identify whether the type of the sample is a nonmetal-based material or a metal-based material; (2) selecting measuring conditions for a fluorescent X-ray analysis depending on the identified type of the sample; and (3) measuring the concentration(s) of one or more element(s) contained in the sample by the fluorescent X-ray analysis according to the selected measuring conditions.

摘要:
It is possible to solve the problem of the conventional fluorescent X-ray analysis that a concentration calculation result can be obtained only after elapse of a time set as a measurement time. In the fluorescent X-ray analysis method and fluorescent X-ray analysis device according to the present invention, a sample measurement condition is set before starting the measurement and the measurement concentration of the element contained in the sample and the measurement accuracy are calculated. When the measurement accuracy has become a value satisfying the predetermined measurement condition, the measurement is terminated and the concentration at that moment is outputted.

An object of the present invention is to shorten the time required by processing, and to simplify the work and increase the number of samples processed, in the X-ray analysis of a specific substance contained in a sample. To achieve the object, a method for assaying the content of a specific substance in a sample 106, comprises a measurement step (S3) of irradiating the sample 106 with X-rays, and measuring the spectrum of the sample 106, and an assay step (S4) of comparing the components of the specific substance in the spectrum of the sample 106 and in a reference spectrum that has been pre-stored for the sample 106, and determining whether the specific substance is contained in the sample 106 in an amount equal to or greater than a specific value.

The image display device of the present invention includes a display panel having a front surface for displaying an image and a rear surface facing a side opposite to the front surface, and a chassis to which a circuit-bearing member is attached. The chassis supports the display panel. The chassis has a frame shape that surrounds the display panel from outside in a direction perpendicular to a thickness direction of the display panel, and that allows the rear surface of the display panel to be exposed. Thereby, heat can be radiated to air directly from the rear surface of the display panel.

The present invention to provide a method of mounting a semiconductor laser component capable of preventing deterioration of laser characteristics and destruction of the semiconductor laser component due to residual stresses as well as preventing decrease of a lifetime due to increase in temperature of the semiconductor laser component. The method of mounting a semiconductor laser device which comprises a step of pressure bonding a semiconductor laser component on a submount by a collet while a bonding member is heated to be fused or melt on a submount by heating a table on which the submount is placed, for example, characterized in that the table and the collet are heated to a temperature higher than a fusing point of said bonding member so as not to occur the heat transfer substantially to a collet, and then heating of the table and the collet is terminated with maintaining the pressure bonding state.
