A method of producing an atomized powder includes: an atomizing step of forming magnetic alloy particles from a molten metal by an atomizing method, to obtain a slurry in which the magnetic alloy particles are dispersed in an aqueous dispersion medium; a slurry concentration step of causing magnetic separation means to separate the magnetic alloy particles from the slurry to form a concentrated slurry having the magnetic alloy particles of more than 80% by mass, the magnetic separation means using a rotary drum including a magnetic circuit part fixedly disposed at a position where at least a part of the magnetic circuit part is immersed in the slurry and an outer sleeve capable of rotating outside the magnetic circuit part; and a drying step of causing drying means using an air flow dryer to dry the concentrated slurry to form a magnetic alloy powder.

A battery is fabricated on the basis of at least one of the following four concepts, i.e., lead terminals passing through a package not lower than the uppermost surface of an electrolyte cell, lead terminals projecting from a package in directions opposite to each other, a film package with a crushed portion expandable for accumulating gas and sheets of gas barrier sealant for keeping the boundaries between component parts of a package sealed; the seal is hardly broken so that the battery is durable and highly reliable.

Film packaged battery having a cupped portion

A film-packed battery includes a battery element and a packing film which houses the battery element and includes a main heat-sealed portion which is formed around the battery element, and a projecting heat-sealed portion which projects from the main heat-sealed portion toward the battery element, and a gas releasing portion formed in the projecting heat-sealed portion and the main heat-sealed portion adjacent to the projecting heat-sealed portion, wherein a distal end of the gas releasing portion reaches the projecting heat-sealed portion and the gas releasing portion connects external air with a heat-sealed interface of the packing film.

Film-packed battery and method of manufacturing the same

In a film-packed battery which stores a battery element () with packing films () and sealed by heat-sealing heat-sealed surfaces of the packing films around the battery element, a heat-sealed portion () projecting toward a battery element is provided at part of a heat-sealed portion (), and a gas releasing portion () is formed close to the projecting heat-sealed portion. A pressure safety valve for safely releasing a gas to the outside when the gas is generated in the battery is provided without lowering the reliability of the battery.

A urine receiver which is sanitary, easy to attach, and furthermore, prevents urine leakage even when a wearer repeatedly changes positions is provided. A urine receiveris implemented in a urine collection processing system wherein urine discharged from the wearer is suctioned into a urine tank via a urethral tube. The urine receivercomprises, at the least: a liquid permeable, air-impermeable sheetwhich is placed opposite of and covering the urethral meatus of the wearer; a leak-proof sheetwhich is placed on the surface of the air-impermeable sheetopposite to the urethral meatus and bonds to the outer border of the air-impermeable sheet; a suction partwhich is provided between the air-impermeable sheetand the leak-proof sheetand to which the urethral tubeis connected; and a gathers partfor sealing the space between the air-impermeable sheetand the wearer's skin surface which is provided on the outer border part of the air-impermeable sheeton the urethral meatus side.
