Abstract: The object of the present invention is to provide a method for producing simply a positive electrode active material which can further increase charge-discharge capacity of secondary batteries when the positive electrode active material is used for positive electrode of secondary batteries, particularly non-aqueous electrolyte secondary batteries. A method for producing a positive electrode active material includes the step of heat-treating a lithium mixed metal oxide represented by the formula Li2MO3 in the presence of a hydride wherein M is at least one element selected from the group consisting of Ti, V, Mn, Fe, Co and Ni.

Abstract: The problem of the present invention is to provide a sulfide solid electrolyte material having excellent ion conductivity. The present invention solves the problem by providing a sulfide solid electrolyte material comprising an M1 element (such as a Li element), an M2 element (such as a Ge element and a P element), and an S element; having a peak in a position of 2?=29.58°±0.50° in an X-ray diffraction measurement using a CuK? line; and having an IB/IA value of less than 0.50 when a diffraction intensity at the peak of 2?=29.58°±0.50° is represented by IA and a diffraction intensity at a peak of 2?=27.33°±0.50° is represented by IB.

Abstract: A conductive resin composition which includes (a) a curable resin and (b) hard spherical carbon formed by coating the surface of a spherical base carbon particle with fine carbon particles and/or pitch-derived fine carbon pieces is used to electrically bond two conductive elements. The conductive resin composition is supplied to a space between areas of at least two works respectively having the areas to be electrically connected to each other, and the conductive resin composition is cured while applying a pressure between the areas.

Abstract: Card-type apparatus and method for generating a zero magnetic field are disclosed. The generator includes a printed wiring board and a pair of spiral circuits located at corresponding locations on the front and rear sides of the printed wiring board. The winding directions of the spirals are opposite to each other for generating mutually canceling magnetic fields, i.e. a zero magnetic field, upon application of electric current. A through hole is provided through the printed wiring board for connecting the spiral circuits, and a pair of power terminals are provided on the printed wiring board for supplying power to the spiral circuits.

Abstract: Disclosed is a liquid epoxy resin composition comprising (A) a liquid epoxy resin, (B) a dimethylpolysiloxane having epoxy groups at its both ends, and (C) a dispersing agent comprising the reaction product of (C-1) a dimethylpolysiloxane having amino groups or carboxyl groups reactive with epoxy resins at its side chains or both ends and having phenyl groups or polyether groups for improving its compatibility with epoxy resins at its side chains, and (C-2) an epoxy resin having the same structure as the component (A). The composition has a reduced internal stress, while maintaining the heat resistance intrinsic to epoxy resins, and has excellent resistance, crack resistance and heat shock resistance.

Abstract: A system for denitrating a starting nitric acid solution by irradiation of microwaves to obtain oxide product of the solution comprises a receiver for receiving the solution, a rectangular oven vessel provided with a bottom plate on which the receiver is put, and a conveying mechanism located below the bottom plate for continuously conveying the receiver on the bottom plate throughout the oven vessel. A microwave generator is operatively connected to the oven vessel for generating microwaves to irradiate the content of the receiver when it passes throughout the oven vessel. The receiver may be rotated and vertically moved when it is subjected to denitration and calcination in the oven vessel.
