摘要： Barium sulfate having a specific crystal structure and optical characteristics is disclosed. The crystals have a plate-like structure of which the aspect ratio is 5-100 and the ratio of the square of the circumference of the plate and the area of the orthogonal projection plane is 20:1-150:1. In a preferred embodiment, a thin film of 25 .mu.m thickness with 20% by weight of the barium sulfate powder concentration has a scattering transmittance of 70% or greater and a total transmittance of 85% or greater. The cosmetic compositions to which the barium sulfate is incorporated exhibits excellent extendibility and adhesion to the skin and can effectively hide the spots or freckles on the skin. The cosmetic composition satisfies both the fine naked skin feeling and the skin covering effect, which have never been satisfied by conventional cosmetic compositions.

摘要： A nuclear magnetic resonance imaging apparatus for deriving a signal from a moving part of an object to be imaged, includes a gradient magnetic field generator for applying a gradient magnetic field to the object; and a radio frequency magnetic field generator for applying a radio frequency magnetic field to the object to present a nuclear magnetic resonance phenomenon. Pulses of a 180 degree pulse method are generated to remove an adverse effect of ununiformity of a static magnetic field; two gradient magnetic fields having the same amplitude and grading oppositely to each other are applied at a certain time interval therebetween to the moving part of the object in the direction of motion of the moving object; a radio frequency magnetic field is generated by applying a pulse in the pulses of the 180 degree pulse method succeeding a 180 degree pulse at the time corresponding to the center of an echo signal generated by the 180 degree pulse, the radio frequency magnetic field making a nuclear spin vector at the stationary part of the object in parallel to the static magnetic field; a resonance signal is detected which is produced from the object upon application of the radio frequency magnetic field; the above process is performed to further obtain another resonance signal, reversing the polarities of the gradient magnetic fields; and a difference between the two resonance signals is derived as a signal from the moving part of the object.

摘要： Disclosed is a light source having an envelope containing therein an anode and a hollow cathode, in which the hollow cathode is supported by a hollow metal cylinder. The hollow cylinder externally extends out of the envelope and a plurality of radiation fins are attached on the outer wall of the externally extending portion of the cylinder. Meshes are provided on the inner wall of the hollow chamber of the cylinder. Water is sealed in the hollow chamber under a reduced pressure to facilitate evaporation. The condensed water is displaced toward a high temperature portion by capillarity. The water is evaporated at the high temperature portion while taking away the latent heat of evaporation. In such an arrangement, the cathode is maintained at a low temperature so that the self-absorption of the spectral line can be reduced.

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： An ion source includes a body having a gas passage and an orifice. A capillary is inserted into the gas passage so that a tip portion of the capillary extends into the orifice. A gas supplier supplies a gas into the gas passage to form a gas flow through the gas passage along the capillary and through the orifice past a tip of the capillary so that the gas flow sprays a sample solution flowing through the capillary from the tip of the capillary. A flow controller regulates a pressure of the gas in the gas passage to adjust a characteristic value F/S to a predetermined value, where F is a flow rate of the gas flow at standard conditions (20.degree. C., 1 atmosphere), and S is a difference between a cross section of the orifice and a cross section of the tip portion of the capillary in the orifice.

摘要： In an optical measurement system and imaging method adapted to measure in vivo information in a living body without harming the living body, light rays of a plurality of wavelengths which are modulated in intensity with a plurality of different frequencies are irradiated on a plurality of irradiation positions on the surface of a living body, and time-variable changes in living body transmitting light intensity levels corresponding to the respective wavelengths and the respective irradiation positions are measured at different positions on the surface of the living body. Light is utilized to image the results of the measurements, in which the measuring time is shortened by estimating fluctuation attributable to the living body, and the presence or absence of a change in measured signal can be decided easily by displaying an estimation signal and a measured signal at a time.
