    Abstract: A heat exchanger includes three flow paths, a first flow path, a second flow path, and a third flow path, which turn spirally in the space formed between an inner cylinder and an outer cylinder are provided. These flow paths are defined by an inner heat transfer body and an outer heat transfer body, and heat exchange is performed through the heat transfer bodies. The heat transfer bodies turn spirally, have a screw shape in an axial cross-sectional view, and are assembled into a screw shape. The flow path area of the first flow path is varied by changing the shapes of a male thread and a female thread, and the second flow path and the third flow path are formed in a spiral shape, allowing for exchange of heat through the heat transfer bodies.

    Abstract: The present invention addresses the problem of providing producing processes for garnet precursor microparticles (a precursor for microparticles of garnet structure) and microparticles of garnet structure. One of the processing processes comprises mixing ions of at least two elements with a basic substances that contain the at least two elements. The thin-film fluid is formed between at least two processing surfaces which are approachably and separably arranged facing each other with at least one of the processing surfaces rotating relative to the other. In the processing process, the precipitated microparticles are garnet precursor microparticles, and the molar ratio between the at least two elements in the garnet precursor microparticles is regulated by controlling the pH of the thin-film fluid after the mixing. Microparticles of garnet structure can be obtained by subjecting the garnet precursor microparticles to heat treatment. Specifically, the yttrium/aluminum molar ratio of yttrium-aluminum-garnet (YAG) precursor microparticles is regulated by controlling the pH of the thin-film fluid after the mixing, YAG being an example of the crystal of garnet structure.

    Abstract: The present invention addresses the problem of providing a method for producing metal microparticles in which the particle diameter and the coefficient of variation are controlled. Using at least two kinds of fluid to be processed including a fluid which contains at least one kind of reducing agent, the fluid to be processed is mixed in a thin film fluid formed between at least two processing surfaces, at least one of which rotates relative to the other, and which are disposed facing each other and capable of approaching and separating from each other, and metalmicroparticles are separated. At this time, the fluid to be processed containing one or both of the fluid which contains at least one kind of metal and/or metal compound and the fluid which contains at least one kind of reducing agent contains a water-containing polyol in which water and a polyol are mixed, and does not contain a monovalent alcohol, and the particle diameter and coefficient of variance of the separated metal microparticles is controlled by controlling the ratio of water contained in the water-containing polyol.

    Abstract: The present invention addresses the problem of providing a method for producing nickel microparticles in which the ratio of crystallite's diameter to the particle diameter of the nickel microparticles is controlled. At least two types of fluids to be processed are used, including a nickel compound fluid in which a nickel compound is dissolved in a solvent, and a reducing agent fluid in which a reducing agent is dissolved in a solvent. Sulfate ions are included in the nickel compound fluid, and polyol is included in the nickel compound fluid and/or the reducing agent fluid. The fluid to be processed is mixed in a thin film fluid formed between at least two processing surfaces (1, 2), at least one of which rotates relative to the other, and which are disposed facing each other and capable of approaching and separating from each other, and nickel microparticles are precipitated. The present invention is characterized in that at this time, the ratio (d/D) of crystallite's diameter (d) to the particle diameter (D) of the nickel microparticle is controlled by controlling the pH of the nickel compound fluid introduced between the processing surfaces (1, 2) and the molar ratio of sulfate ions with respect to nickel in the nickel compound fluid.
