摘要:
A method for separating a hydroxide ion, characterized in that a hydroxide ion (OH - ) in an aqueous solution is separated by a chromatograph. The method allows the separation and the measurement with high precision of a hydroxide ion which has not been achieved by a conventional pH titration method and pH meter method, and further allows the selective extraction and concentration thereof.
摘要:
A method for the separation of hydrogen ion, characterized in that a substance having a conjugate base (A - ) of an acid (HA) as a functional group is used as a stationary phase, and an electrolyte containing a cation having a larger ion exchanging force than that of hydrogen ion is used as an eluent. The method allows the selective separation of hydrogen ion and the quantitative analysis thereof with high precision.

Laminate unit C obtained by fixing article B to support plate A through pressure sensitive adhesive double coated sheet 1 capable of being deformed by heating to thereby exert a detachment effect is held between a pair of sandwiching means, the sandwiching means so arranged as to enable interposition of the laminate unit C. The laminate unit C is heated by heating means 7 so that the pressure sensitive adhesive double coated sheet 1 is deformed to thereby reduce an area of contact of the pressure sensitive adhesive double coated sheet 1 with the article B with the result that the article B comes up from the pressure sensitive adhesive double coated sheet 1. Thereafter, the article B is detached from the pressure sensitive adhesive double coated sheet 1. Thus, there can be provided a method of detaching an article fixed through a pressure sensitive adhesive double coated sheet and a detachment apparatus therefor, which realize effective detachment of articles and ensure suitability to processing by an automatic line.
摘要:
A method of producing a composite material of a bismuth 2212 phase and a metallic substrate, wherein the first and second baking are conducted as an isothermal heat treatment. According to this process, temperature control is easy, high productivity is obtained, and the property of the critical current density is improved.
摘要:
The present invention provides a recording material comprising a support, a recording layer provided on the support, and at least one protective layer provided on the recording layer, wherein, the recording layer contains a coloring component A encapsulated in heat-responsive microcapsules, and a substantially colorless compound B, which is outside the heat-responsive microcapsules and has a coloring site that colors when reacted with the coloring component A, and wherein, at least one of the protective layer or a layer adjacent thereto comprises a layer containing titanium oxide.
摘要:
A hydrodemetalation catalyst of a hydrocarbon oil comprising a support and a catalyst component supported by the support, and provided on a part of a catalyst surface with a coating layer made of an inactive material not substantially having a demetalation function and not substantially permeating a reaction fluid. Preferably, this catalyst has a reaction flow path inside the catalyst through which a reaction fluid flows, and is preferably having a cylindrical or honeycomb structure having a single or a plurality of through-holes. In a hydrodemetalation treatment of heavy oils using such a hydrodemetalation catalyst of a hydrocarbon oil, fixation of catalysts can be prevented, a rapid rise of differential pressures can be prevented by keeping spaces between the catalysts, and a continuous operation can be carried out for a long time.

For the purpose of improving optical and mechanical properties, the present invention provides a cesium-lithium borate crystal, of which the chemical composition is expressed by any of the following formulae: Cs1-xLi1-yMx+yB6O10 , and Cs2(1-z)Li2LzB12O20 (where, M is an alkali metal element, and L is an alkali earth element), in which an exotic element is doped, or which is annealed.
摘要:
The present invention provides a method for stabilizing an oxide-semiconductor interface, which is free from the formation of an interface layer (reactive layer) between a semiconductor and an interface oxide and which thereby allows satisfactory exhibition of performance capabilities of a functional oxide and achievement of the stability of oxide-semiconductor interface, yet independent of temperature; it also provides a stabilized semiconductor.
