    摘要: The object of this invention is to provide an atomic absorptiometer and a metal specimen atomic vapor generation apparatus used in the atomic absorptiometer, which enable a light absorption measurement based on the Zeeman effect highly capable of background correction and eliminate the need for the troublesome work of dismounting a magnet. For this purpose, the following configuration is employed. First, the specimen, hydrochloric acid, and sodium borohydride are delivered and mixed by the peristaltic pump 10 to produce a metallic hydride. The generated gas-liquid mixture solution is separated by the separator 12 into a specimen gas and liquids. The separated specimen gas is introduced into the heating section 30. Electricity is supplied from the power source 28 to the specimen heating section 30 where the specimen gas introduced is heated and separated into hydrogen and a specimen metal vapor to be measured. The specimen metal vapor is then introduced into the measuring section 34 arranged between magnetic poles of the magnet 32 where the metal vapor is subjected to the atomic absorptiometric analysis based on the Zeeman effect.

For this purpose, a graphite tube type cuvette mounted in a graphite atomizer furnace for an atomic absorption spectrophotometer comprises a large-diameter portion for retaining a sample in place, a small-diameter portion connected to the large-diameter portion and having a smaller diameter than the large-diameter portion, and a step portion for demarcating between the large-diameter portion and the small-diameter portion. The graphite tube type cuvette is formed such that its cross-sectional area in a plane perpendicular to the direction of passage of an electric current supplied to the cuvette is the same in any of the large-diameter portion, the small-diameter portion and the step portion. The amount of resistance heat is thereby also the same in any portions.

    摘要: A grinding machine provided with an apparatus for changing a feed rate of a grinding wheel relative to a workpiece just before the grinding wheel comes into contact with the workpiece. An electrode device is mounted adjacent to the grinding wheel and connected to an electric power source for applying a potential to the surface of the grinding wheel. A detecting device detects a difference of potential between the grinding wheel and the workpiece to generate an output voltage. A memory device memorizes the output voltage detected when the grinding wheel is distant from the workpiece. A setting device reduces the memorized output voltage at a predetermined rate to provide a reference voltage corresponding to a predetermined gap between the grinding wheel and the workpiece. A comparator circuit compares the output voltage with the reference voltage to generate a feed rate changing signal when the output voltage attains the reference voltage. A control device controls a feed device so as to change the feed rate of a wheel slide in accordance with the feed rate changing signal.

    摘要: A size of particle or defect in an object is measured. A laser beam is guided through an optical system into the object. A light receiving element receives scattered light from a particle or a defect in the object. A scattering image is formed by an image processor from the scattered light thus received. The size of particle or defect is obtained by integrating a scattering intensity of the scattered light. Also, a size distribution of particle or defect in an object may be acquired by detecting a maximum scattering intensity of each particle or defect. A polarization dependency of scattering may be checked as well.
