Abstract: A biometric information processing device (1) includes a brain wave detecting unit (10), a control unit (20), and a movement assisting unit (30). The brain wave detecting unit (10) detects biometric information in at least one brain region from among a plurality of brain regions that are selectable in accordance with a body part that is a target of function recovery or function improvement. The control unit (20) determines, based on the detected biometric information, at least one activity state in the brain including the location of the brain region(s) that is (are) activated in a subject while attempting to move the body part, and an activation level of such activated brain region(s). When the control unit (20) determines that the at least one activated state of the brain satisfies a predetermined condition, the movement assisting unit (30) executes a predetermined motion to assist movement of the body part.

Abstract: A process for producing a superconductor of an oxide system, which comprises uniformly mixing metal elements for constituting the oxide system at least partly in the form of alkoxides having CN.sup.--, X.sup.-- wherein A is a halogen atom and/or an amine, with the rest, if any, being in the form of acetylacetonates, carboxylates and/or water-soluble inorganic compounds to obtain a homogeneous mixture, and sintering the mixture.

Abstract: An improved method for producing superconductive oxide substance, wherein a solution containing therein a plurality of elements to constitute the superconductive oxide substance is atomized into mists, then the thus atomized mists are transported on a carrier gas into a chemical reaction device, and, after the chemical reaction in this chemical reaction device, the superconductive oxide substance is deposited on a substrate in a desired shape, with further heat-treatment of the thus deposited superconductive oxide substance in an oxygen-containing atmosphere at a temperature ranging from 200.degree. C. to 1,200.degree. C.
