A process for production of a chain metal powder, which comprises the steps of reducing metal ions contained in an aqueous solution, while applying a magnetic filed to the solution, in the presence of both a reducing agent capable of generating a gas during the reduction of metal ions and a foamable water soluble compound, through the generation of a gas, a bubble layer on the surface of the aqueous solution to form a chain metal powder, separating the bubble layer formed on the surface of the aqueous solution from the solution, and collecting the chain metal powder contained in the bubble layer.

Process for production of chain metal powders, chain metal powers produced thereby, and anisotropic conductive film formed by using the powders

A chain metal powder, which is free from branches and has a small distribution of the chain length, can be produced by a process of reducing metal ions contained in an aqueous solution, while applying a magnetic field to the solution containing ferromagnetic ions, in the presence of a polymer compound comprising repeating units of the formula (1): and repeating unit of the formula (2): or repeating unit of the formula (4); or a process which comprises the steps of reducing metal ions contained in an aqueous solution, while applying a magnetic filed to the solution, in the presence of both a reducing agent capable of generating a gas during the reduction of metal ions and a foamable water soluble compound, through the generation of a gas, a bubble layer on the surface of the aqueous solution to form a chain metal powder, separating the bubble layer formed on the surface of the aqueous solution from the solution, and collecting the chain metal powder contained in the bubble layer.

Solid ion conductive polymer electrolyte and composition and production

The present invention is directed to a metal/hydrogen alkaline storage battery, which comprises a positive electrode of a metal oxide, a negative electrode of a hydrogen-storage alloy, and a separator impregnated with an alkaline electrolyte and placed between the positive and negative electrodes. The electrodes and separator are housed within a sealed type battery casing. The casing has a device for maintaining the pressure in the battery in a selected range of from an equilibrium pressure required for absorbing hydrogen by the negative electrode to about 20 kg/cm.sup.2.
