摘要:
Additional charge of a solid raw material 13 in the shapes of granules/lumps, low in raw material cost, and with no risk of cracking, is performed into a molten raw material 14 in a crucible in a static manner without solidifying a surface of the molten raw material 14 in the crucible 3. A bottom of a cylindrical raw material vessel 10 made of a material non-meltable when being in contact with the molten raw material 14 in the crucible 3 is closed with a bottom cover 11 made of a material meltable and removable when being in contact with the molten raw material 14 in the crucible 3. The raw material vessel 10 in a state of being filled with the solid raw material 13 in the shapes of granules/lumps is hung down above the crucible 3 to immerse the lower portion thereof into the molten raw material 14 in the crucible 3. The bottom cover 11 is molten and removed by putting the bottom cover 11 into contact with the molten raw material 14 in the crucible 3 to thereby charge the solid raw material 13 in the raw material vessel 10 into the molten raw material 14 in the crucible 3.

To provide a method for selectively amplifying a target nucleic acid and a method for detecting a nucleic acid by the method, which are useful as a method for synthesizing the nucleic acid. A method for amplifying a nucleic acid sequence (EVA (Endonuclease V-dependent Amplification) method) which selectively amplifies a target nucleic acid in a sample, by the use of an oligonucleotide primer containing a base which can be recognized by an endonuclease V, the endonuclease V and a DNA polymerase having a strand displacement activity, and a method for detecting a nucleic acid by the method.

A novel mutant endonuclease V not exhibiting a nonspecific nucleic acid cleavage activity but showing a specific activity. The present invention relates to a mutant endonuclease V not exhibiting a nonspecific nucleic acid cleavage activity but having a specific activity, to a gene coding for the endonuclease V, to a recombinant DNA containing the gene, to a transformant or transductant containing the recombinant DNA, and to a method for producing the endonuclease V. The present invention also relates to a method of using the endonuclease V for nucleic acid cleavage, and to a reagent kit for detection or modification of a nucleic acid or gene that contains the endonuclease V.
摘要:
A method of detecting an obstacle that disturbs a printing operation to be performed on a printing surface of a printing portion of a workpiece by a printing head of an ink-jet printer such that the printing head and a planar platen on which the printing portion of the workpiece is set are moved relative to each other between a first position and a second position, with a predetermined spacing maintained between the printing surface of the workpiece and the printing head in a direction perpendicular to the printing surface, wherein the obstacle existing on a plane of printing by the printing head is detected by a sensing device, by scanning the predetermined spacing in a direction intersecting a direction of a relative movement of the printing head and the platen, while the printing head and the platen are moved relative to each other between the first and second printing positions. Also disclosed are an ink-jet printing method and printer wherein the obstacle is detectable.

In supplying crystalline materials in the Czochralski method, it is made use of an apparatus equipped with an inner vessel having an opening portion at the lower part or bottom thereof, which is to be charged with a granular solid material, an outer vessel containing the inner vessel therein with the function of sliding movement and thus closing the opening portion, and pull-up means for suspending the inner vessel and outer vessel in a manner causing them to ascend or descend, wherein the opening portion is opened through a sliding motion of the inner vessel or outer vessel for additional charging or recharging of the solid material into the molten material in the crucible, with the result that the molten material in the crucible can be prevented from splashing, the additional charging can be carried out in a static manner, the material cost becomes low and there is no risk of cracking due to rapid heating. Further, the productivity in silicon single crystal growing can be improved, the crucible can be used efficiently and the life of the furnace parts can be prolonged and, as a result, the cost of silicon single crystal growing can be markedly reduced.
