    Abstract: Disclosed are: a process for producing a negative electrode precursor material for use in a battery, which enables the production of a negative electrode that has good adhesion between an Al current collector and an Sn coating film contained therein and therefore can be reduced in thickness, has good current collectivity, and does not undergo deformation or generation of dendrites during being operated; the negative electrode precursor material; and a battery equipped with the negative electrode precursor material as a negative electrode. Specifically disclosed is a molten salt battery (1) which comprises a positive electrode (2) comprising an Al-made current collector (21) and an active material layer (22) formed on the current collector (21), a separator (3) comprising a glass cloth impregnated with a molten salt that serves as an electrolyte, and a negative electrode (4) comprising a Zn coating film (42) and an active material layer (43) both formed on an Al-made current collector (41), wherein the positive electrode (2), the separator (3) and the negative electrode (4) are contained in an almost rectangular parallelepiped Al-made case (5). The active material (43) can store and release Na ions contained in the molten salt.

    Abstract: An anisotropic conductive film, and its production method, especially suitable for mounting a semiconductor package and sufficiently satisfying the requirements of higher density mounting because short circuit does not occur in the plane direction of the film even if the pitch of electrodes is small, or suitable for mounting a contact probe because conductive connection not fused with a high current can be ensured with a lower pressure and even a high frequency signal can be dealt with. The anisotropic conductive film contains metal powder having such a shape that many fine metal particles are linked as a conductive component, wherein the length of the chain of metal powder is set not longer than the distance between adjacent electrodes being bonded conductively when a semiconductor package is mounted, and the diameter of the chain is set in the range of 1 mu m-20 mu m when a contact probe is mounted. At least a part of the film is formed while orienting a chain formed of a paramagnetic metal with a magnetic field.

    Abstract: This invention aims at providing a method of obtaining fine alloy powders, which are extremely small in particle size, high in purity, and uniform in composition, providing fine alloy powders obtained by this method, and providing molding materials, slurries, and electromagnetic shielding materials, which use these fine alloy powders. This invention provides a fine alloy powder production method, which is characterized in that after performing the process of mixing at least a trivalent titanium compound and a complexing agent, which binds with the trivalent titanium ion, in an aqueous solution containing two or more types of metal ion, the two or more types of metal are made to deposit simultaneously. This invention also provides fine alloy powders, which are obtained by the above-described method, that are 1 to 100nm in particle size, and preferably exhibit the characteristics of soft magnetic material, and molding materials, slurries, and electromagnetic shielding materials, produced by dispersing an abovementioned fine alloy powder in a resin.
