PURPOSE:To extend a charge-and-discharge cyclic life by adding tin oxide doped with antimony trioxide in a positive electrode active material. CONSTITUTION:Tin oxide doped with antimony trioxide is added in a positive electrode active material to be supported by a grid. Thereby, a quantity of tin oxide to be added shall be in the range of 1-20 weight % to the quantity of the active material and a ...

PURPOSE:To prevent a life termination caused by battery casing breakage at the final period of life by specifying internal dimensions of the casing as against the plate size. CONSTITUTION:A gradual elongation of anode plate during the use of battery causes a decrease in capacity. The internal dimension of a battery casing is specified 110% or more of the plate size, in order to avoid abutting of t...

PURPOSE:To prevent contaminated air from diffusing to respective rooms and also to prevent malodor contamination and bacteria propagation within a heat exchanger by providing a damper operating in linkage with lighting of an illuminator of a toilet to communicate the suction port of the toilet with the outlet side of the heat exchanger of an exhaust passage, and operating in linkage with putting-o...

Crosslinked macromolecular products having a perfluoropolyether structure, wherein the crosslinking is due to C-C bonds between carbon atoms of different perfluoropolyether chains, said crosslinked products being obtainable by irradiation of certain perfluoropolyethers containing at least three groups of the formula arranged along and at one or both ends of the chain; the crosslinking C-C b...

A composition obtained by mixing fly ash, calciumsulphate hemihydrate and oxisludge, a product caught from gases emanating from converters during steel production. Oxisludge containing substantial amounts of iron is used in an amount comprised between 0,2 and 10%, preferably 1 to 5%. The composition is a loose mass or consists of granular products.

A conditional replenishment video data transmission system involves the transmission of updating digital data for clusters of consecutive picture elements, all or most of which show a change since the previous frame, in lines of a raster over an image to be transmitted. The lines of the raster are numbered cyclically in groups of 8, the numbers being part of line synchronizing code words, and the ...

A furnace burns coal where the coal is decreased to a fine size to expand the surface of the carbon in the coal to a predetermined amount of free oxygen from air to militate against reduction of alkali compounds in the coal. Further, the temperature of the combustion is controlled to a predetermined maximum by recirculation of cooled flue gas to complete the control over the alkali compounds in th...

PURPOSE:To release the long-time exclusively used state of a commonly used file, and to reduce the logging quantity and the check quantity, by providing a reexecuting part for an updating condition resource and inhibiting exclusively the updating of the commonly used file during the time from an updating processing request to the end of the updating by an executing part. CONSTITUTION:In accord...
