摘要： A microscope turret assembly and a microscope with the turret assembly are provided so that active use is made of the space formed on an underside surface of a turret by providing an illuminator or an optical detector therein. The turret retains multiple objective lenses and, by rotation thereof, enables the selection of a single objective lens. At least a part of an illuminator that casts light on an observed specimen via the selected objective lens, or a part of an optical detector that detects light from an observed specimen, is located in the space.

摘要： Fine metallic nitride powders having a high purity are prepared, without causing any plugging or other problems in the reaction apparatus and with easy heat control of the reaction, by reacting a metallic halide with liquid ammonia in the presence of an organic solvent which has a specific gravity higher than that of liquid ammonia, and also is not miscible or is only slightly miscible with liquid ammonia at a reaction temperature. The process according to the present invention is effected by introducing the metallic halide into the lower organic solvent layer of the reaction system.

摘要： An AF dark field illumination device and an objective lens are moved in unity. A tissue sample in a Petri dish is illuminated by infrared light incident with an oblique angle from an LED light source. The casting of the infrared light causes scattered light from the tissue sample. A part of the scattered light passes through the objective lens, thereby forming a dark-field microscope image, which is captured by a CCD camera. The sharpness of the dark-field microscope image is dependent upon the position of the objective lens. The position of the objective lens at which the dark-field microscopic image exhibits the highest sharpness is determined to be the focus position.
