摘要： A cuvette used in a flameless atomizer is hollow and includes an opening at both ends and a hole in a radial direction substantially at its central portion. The cuvette is made of a conductive material and Joule-heated by currents flowing therethrough. The interior of the cuvette is divided substantially into three sections: a sample mount section at which a sample introduced through the hole of the cuvette is disposed; a light beam path section through which light incident from the opening at one end of the cuvette passes and goes out of the opening at the other end; and an absorption cell section at which the light beam path section intersects with atomic vapors generated from the sample disposed at the sample mount section. The electric resistance of the cuvette is made smaller at the sample mount section than at a portion near the absorption cell section. This allows the higher temperature of the portions near the absorption cell section than that of the sample mount section. Therefore, almost all of the atomic vapors in the cuvette exist at the absorption cell portion, and the application of a magnetic field to the absorption cell section allows a great improvement in analysis precision and sensitivity of the flameless atomizer for atomic absorption analysis using a Zeeman effect.

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.

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 light beam emitted by a hollow cathode lamp is concentrated on a central portion of an electrothermal sample atomizing apparatus by a concave mirror. The light concentrated on the central portion of the electrothermal sample atomizing apparatus is further concentrated on a central portion of a flame produced in a burner type sample atomizing apparatus by a lens. The light traveled through the burner type sample atomizing apparatus is condensed by a concave mirror, reflected by a flat mirror, and concentrated on an entrance slit of a spectroscope.

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.
