Abstract: PURPOSE:To manufacture a permanent magnet by a method wherein an alloy comprising principal components such as R(a rare-earth element containing Y), Fe, and B is melted and cast, next a cast ingot is heat-processed at a specific temperature, and next it is heat-treated at a predetermined temperature for a predetermined time. CONSTITUTION:In a method of manufacturing a permanent magnet, R (R is at least one kind of rare-earth element containing Y), Fe, and B are used as raw material principal components, an alloy comprising the principal components is melted and cast, next a cast ingot is heat-processed at a temperature of higher than 500 deg.C, and next it is heat-treated in a temperature range of 250 to 1100 deg.C for more than 4 hours. The rare-earth is employed by combining one or more kinds of Y, La, Ce, Pr, and Nd, etc., with each other.

Inventor: HAMADA KEINOSUKE
IPC: H01M6/34
Filed: 1994-05-02
Abstract: PURPOSE:To provide a battery free from environmental pollution and requiring no charge by using an electrically conductive material reactive with H in a negative electrode, a material less reactive with H<+> but passing an electron in a positive electrode, and a liquid which dissociates to release H<+> in an electrolyte. CONSTITUTION:A material with low ionization tendency, preferably carbon is used in a positive electrode, a material with high ionization tendency is used in a negative electrode for high voltage, and use of water or seawater is allowable as an electrolyte. Two kinds of electrodes are immersed in the solution to produce a water battery. Since electromotive force of the water battery is produced by the reaction represented by equations I and II, electric power is generated while electrode materials and water exist. When the electromotive force is decreased by decrease in H concentration in the electrolyte and stick of hydroxides on the electrode attendant on repeated discharge, the electromotive force is recovered by supplying an acid and brushing or ultrasonic cleaning of the electrode. The water battery is optimum as a power source of maritime applications, especially for sending distress signals.
