A method of manufacturing a surface-coated cutting tool includes: forming an aluminum oxide layer having a layer thickness of 0.05 to 5 μm and an α-alumina structure with a corundum type crystal structure on a cutting tool body using a sol-gel method. The step of forming includes adding an alcohol to aluminum alkoxide; adding an acid; stirring the mixture at 10° C. or lower to form a sol; applying the sol on a surface of the cutting tool body or an outer-most surface of a hard-coating layer formed on the surface of the cutting tool body; performing a drying process at least once, the applied sol being dried at 100 to 400° C. in the drying process; and annealing the cutting tool body with a dried sol layer at 500 to 1000° C.

摘要:
The present invention provides a novel NMR metabolomics method for observing an animal by labeling the animal itself. A labeled animal labeled with a stable isotope is produced by feeding an animal a labeled food labeled with the stable isotope. Metabolism of a biological substance in the animal is analyzed based on nuclear magnetic resonance data of the biological substance containing the stable isotope. The nuclear magnetic resonance data is acquired by performing NMR measurement on a body of the labeled animal, a portion of the body, or an extract.
摘要:
The present invention provides a method of analyzing metabolism of a plant in which measurement sensitivity for nuclides such as 13C and 15N having low natural abundance ratios is improved using NMR. A labeled plant uniformly labeled with a stable isotope is produced by providing the plant with a nutrition source labeled with at least one type of stable isotope while growing the plant from a seed or a germinating seedling. The metabolism of a biological substance in the plant is analyzed based on NMR data of a biological substance that contains the stable isotope. The NMR data is acquired by performing NMR measurement on a body of the labeled plant, a portion of the body, or an extract.
摘要:
For higher thermal conductivity, stronger adhesion strength, excellent insulating characteristics, and multilayer interconnection, an aluminium sintered body for circuit substrates comprises a novel conductive metallized layer on the surface of the sintered body. The metallized layer comprises at least one element selected from the first group of Mo, W and Ta and at least one element selected from the second group of IIa, III, IVa group elements, lanthanide elements, and actinide elements in the periodic table, as the conductive phase element. The first group element serves to improve the heat conductivity and resistance, while the second group serves to increase the wetness and adhesion strength between the insulating body and the metallized layer. Further, the plural insulating ceramic bodies and the plural metallized conductive layers can be sintered simultaneously being stacked one above the other to permit a multilayer interconnection.
