Abstract: A bottle type fire extinguisher structure includes a high-pressure aluminum bottle. A seal cover of the high-pressure aluminum bottle is provided with a positioning disc. The positioning disc has engaging blocks for engagement of the seal cover. The seal cover is provided with a press control head having a flared nozzle. The upper end of the positioning disc is provided with a cap to cover the press control head. The cap has an opening and a notch. The inner surface of the cap is provided with an annular protruding rib to be fitted to the positioning disc, such that the cap and the positioning disc are assembled together. There is no need to open he cap. The user's finger passes the notch to press the press control head, the fire-extinguishing chemical is sprayed out through opening. Through the flared nozzle, the fire-extinguishing chemical can be sprayed further and aimed at the fire exactly to put out the fire instantly.

Abstract: A LED module with separate heat-dissipation and electrical conduction paths is disclosed, having a metal substrate; a plastic layer, including one or more hollow regions, and attached to the metal substrate; one or more conducting elements attached to the plastic layer; one or more LED chips positioned in the one or more hollow regions of the plastic layer and directly attached to the metal substrate; and a plurality of conducting wires for electrically connecting the one or more conducting elements and the one or more LED chips; wherein inner sides of the one or more hollow regions include one or more inclined surfaces each having an included angle with an upper surface of the metal substrate, and the included angle is between 90˜180 degrees.

Abstract: Methods for merging files and related systems. A first file comprising a plurality of columns is provided. Each column comprises at least one data field for a row corresponding to a string identification. It is determined whether the string identification corresponding to the row is in a second file. If the string identification is in the second file, data for the row corresponding to the string identification in a first column of the second file is written to the row in the first column of the first file. If the string identification is not in the second file, data for the row in a second column of the first file is copied to the row in the first column of the first file.

Abstract: A multi-language system for quickly selecting a font file corresponding to a character includes a font database and a code allocation table. The font database contains at least one character code range and at least one font-storage unit. Each font-storage unit is for storing at least one font file corresponding to a natural language, and each font file corresponds to a character code. A method for quickly selecting the font file includes finding a character code range containing the character code from the code allocation table according to the character code to obtain a font-storage unit corresponding to the character code; obtaining a font file address of a font file corresponding to the character code from the font-storage unit according to the character code; and selecting the font file corresponding to the character code from the font-storage unit according to the address of the font file address.

Abstract: A multi-language system containing a language information module and a related method capable of updating language information are provided.

Abstract: A liquid coenzyme reagent comprises the coenzyme nicotinamide adenine dinucleotide (NAD), or nicotinamide adenine dinucleotide phosphate (NADP), and a sulfhydryl compound capable of counteracting the inhibitory effects of NAD (or NADP) degradation products on LD-L activity. The reagent is maintained at a pH of less than about 31/2. The liquid reagent has a shelf life of at least about 2 years, maintaining a LD-L activity of at least 90% that of the reagent when fresh, when stored at a temperature of from 2.degree.-8.degree. C.
