摘要:
According to the scientific phenomenon evaluation device of the present invention, a test liquid is injected into the first reservoir while sample liquids are injected into the second reservoirs. When the test liquid is supplied to the second reservoirs by being caused to flow through the branching-structure channel, the test liquid and the sample liquid mix and react with each other to cause, for example, a scientific phenomenon such that the colors of the sample liquid change. Thus, the plurality of sample liquids can be evaluated by injecting the test liquid one time. In this case, the scientific phenomenon can be grasped with a single glance since at least the scientific phenomenon in the second reservoirs is visually recognizable. Moreover, the scientific phenomenon evaluation device of the present invention can be effectively used as a portable pH measurement experimental device.

In the scientific phenomena evaluation device of the present invention, a plurality of elongated grooves each having a cross-sectional area of not more than 1 mm2 are formed, an end of each of the plurality of flow passages joins in at one meeting point and furthermore, a liquid absorption device is provided. Therefore, it is possible to qualitatively observe scientific phenomena, such as the dispersion phenomena of molecules. Also, accuracies sufficient for experiencing high technologies, for example, various phenomena such as the diffusion phenomenon of a liquid, heat transfer phenomenon of a liquid, mixing phenomenon of liquids and chemical reactions of a liquid that occur in this fine flow passage are obtained, consumption of chemical agents and the like is small and environmental burdens are small. Therefore, this evaluation device of scientific phenomena is appropriate as an educational tool for scientific experiments.

The mixing state of static mixing is optimized, so that it is possible to form silver halide emulsion particles in small sizes with an excellent mono-dispersion characteristic. An aqueous solution of haloid salt is blown out from a first nozzle into a mixing chamber as a rectilinear flow of turbulent flow, and before eddy viscosity formed when the rectilinear flow is blown out from the first nozzle of a small diameter to the mixing chamber of a greater diameter reaches a maximum, or before a maximum flow speed of the rectilinear flow is reduced to {fraction (1/10)} or below, an aqueous solution of silver nitrate is blown out from a second nozzle as a crossflow of turbulent flow which crosses the rectilinear flow at a substantially right angle and is entrained by the rectilinear flow, so that the two solutions are allowed to mix and react with each other instantaneously, and a liquid resulting from the mixing and reaction is discharged from a discharge duct.

At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.

摘要:
According to the present invention, a continuous layer liquid used as a continuous layer of a diffusion phenomenon is injected into the first reservoir, and passed through the channels to the second reservoirs to fill the plurality of radially formed channels with the continuous layer liquid. Then, a predetermined amount of diffusion experiment reagent, for example, a coloring liquid used as a diffusion substance of the diffusion phenomenon is injected into the first reservoir. This causes the diffusion experiment reagent to be diffused from the first reservoir to the second reservoirs only by the diffusion phenomenon. At this time, the radially formed channels have the different sectional areas, and thus the diffusion experiment reagent is diffused through the channels at different velocities. This allows the diffusion phenomena that occur in the micro channels or the diffusion velocities to be observed or measured with ease using an inexpensive device.
