摘要： Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled. In this calcination step, after subjecting the formed body to primary sintering at a temperature of 1, 600-1, 900 K, the resulting primarily-sintered body undergoes hot-isotropic-press sintering (or HIP processing) at a temperature of 1,600-1,900 K.

摘要： Provided is a method for manufacturing a translucent polycrystalline material with optical properties continuously varying in the material. A slurry including a group of single crystal grains that are acted upon by a force when placed in a magnetic field is immobilized in a gradient magnetic field with a spatially varying magnetic flux density and then sintered. For example, where a slurry including a group of single crystal grains of YAG doped with Er and a group of single crystal grains of YAG undoped with a rare earth material is immobilized in a magnetic field with a non-uniform distribution of magnetic field intensity, the region with a strong magnetic field becomes a laser oscillation region that is rich in Er-doped YAG and has aligned crystal orientations, whereas the region with a weak magnetic field becomes a translucent region rich in YAG undoped with a rare earth material. A polycrystalline material can be manufactured in which a core with laser oscillations and a guide surrounding the core and guiding excitation light to the core are obtained at the same time.

摘要： A method for forming II-type cellulose, which comprises introducing together a slurry having water and a I-type cellulose dispersed therein and water in the state of high temperature and high pressure to a tubular reactor (28), contacting the I-type cellulose with a hot water in a supercritical state or subcritical state for a predetermined time in the tubular reactor (28), to thereby decompose a part of the hydrogen bonds in the I-type cellulose and dissolve the I-type cellulose into the water in a supercritical state or subcritical state, cooling a cellulose solution discharged from the tubular reactor (28) in a cooler (30) to room temperature or lower, followed by allowing to stand, to thereby precipitate crystals of II-type cellulose having a molecular weight lower than that of the I-type cellulose, and separating the resultant II-type cellulose from a solvent. The method allows the preparation of pure II-type cellulose by the use of a simple process.

摘要： A method of determining the base sequence of a nucleic acid by detecting a single dye molecule, which involves the following steps: (1) fixing to a solid surface a nucleic acid molecule or a primer having a sequence complementary to a part of the sequence thereof; (2) annealing the above nucleic acid molecule or primer with the corresponding primer or nucleic acid molecule; (3) supplying a solution containing DNA polymerase and a dye-labeled dNTP or RNA polymerase and a dye-labeled NTP to the fixed nucleic acid molecule and reacting the nucleotide with the 3'-end of the primer to thereby allowing the polymerase to incorporate the nucleotide forming a base pair with the base opposite to the reaction site; (4) detecting the dye-labeled dNTP or NTP thus bonded; (5) disrupting the dye molecule of the bonded dye-labeled dNTP or NTP; (6) repeating the procedures of the steps (3) to (5) while successively changing the type of the dye-labeled dNTP or NTP so as to bond the dNTP or NTP forming a base pair with the nucleotide of the nucleic acid molecule; and (7) determining the base sequence of the nucleic acid molecule based on the dNTP or NTP thus bonded.
