  • Publication number: 20150125592
    Abstract: A manufacturing method of a fiber-containing dispersion includes obtaining a crude dispersion 20 containing fibers 10 and removing foreign substances by passing the crude dispersion 20 through a filter medium 40. The filter medium 40 is constituted with a plate material having a plurality of opening portions 42 through which the crude dispersion 20 is passed and non-opening portions 44 which partition the plurality of opening portions 42 from one another. The filter medium 40 satisfies the following relational expressions. ½ of average major-axis length of fibers?Minor-axis width of opening portions 42?5 times the average major-axis length of fibers 10??(1) Minimum width of non-opening portions 44?Average major-axis length of fibers 10??(2) Aperture ratio of filter medium 40?0.9%.

  • Patent number: 7344378
    Abstract: 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.

  • Publication number: 20070071640
    Abstract: 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.
