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.

摘要： A stress-tolerant transgenic plant comprising an exogenously-introduced polynucleotide encoding a protein kinase which activates stress-responsive transcription factors. The polynucleotide may encode a protein kinase which comprises SEQ ID NO: 2 (SRK-2C) or a sequence having a significant degree of similarity with SEQ ID NO: 2. The transgenic plant has increased stress-tolerance to environmental stresses, such as to dehydration, osmotic stress or low temperature stress, compared to a similar non-transgenic plant.
