  • Patent number: 10863005
    Abstract: A data transmission method for transmitting compressed data is disclosed. The method includes: classifying transmission target files into transmission groups; calculating, for each of the transmission files, a first compression time taken to compress the file by a first compression system and a first transmission time taken to transmit the file after being compressed by the first compression system; and determining, for each of the transmission groups, transmission order of files belonging to the transmission group based on the first compression time and the first transmission time.

  • Patent number: 8173804
    Abstract: The invention provides a process for production of mirtazapine as a convenient process for obtaining mirtazapine from a reaction mixture obtained by cyclization of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol with concentrated sulfuric acid, at high purity and in a form suitable for safe use as a drug. The production process for mirtazapine is characterized in that a reaction mixture obtained by cyclization of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol with concentrated sulfuric acid is diluted with water, the dilution is alkalinized in the presence of propanol, the mirtazapine is extracted with propanol and the mirtazapine is crystallized from the extract.

  • Patent number: 4173061
    Abstract: Scrap bars of extruded goods are reclaimed as billets for extrusion. An external force is applied to an aggregate of scraps, in which the scraps are piled in the form of a bundle having a predetermined length, so as to reduce its size in directions perpendicular to the longitudinal axes of the scrap bars, thereby forming a billet. The extruded goods produced from the billet have almost no pores and are not inferior to those produced from cast billets.
