  • Patent number: 10094001
    Abstract: Method for producing eutectic copper-iron alloy in which crystal grain fragments containing iron are dispersed in a copper matrix, includes: a charging step charging a first melting furnace (MF) and second MF respectively with electrolytic-copper and pure iron grain fragments; molten copper (MC) deoxidizing step heating electrolytic-copper to at least melting-point in the first MF, melting and deoxidizing the electrolytic-copper; molten iron (MI) deoxidizing step heating pure iron to at least melting-point in the second MF, melting and deoxidizing pure iron; MI transfer step increasing the MI temperature generated in the second MF; transferring the MI to a primary reaction furnace; MC transfer step increasing the MC temperature in the first MF to at least the iron melting-point; transferring the MC to the primary reaction furnace; and a reaction step causing a crystallization reaction between copper in the MC and iron in the MI in the primary reaction furnace.

  • Patent number: 7697976
    Abstract: The invention relates to a non-invasive method to diagnose the changes of molecular structures of organism tissues from body surface and a dedicated apparatus. The apparatus is comprised of a Fourier Transform infrared spectrometer and a set of additional accessories. Said additional accessories include a mid-IR fiber optics sampling attachment, a fiber coupling part, and an infrared detector part. The detection method is comprised of placing the ATR probe of the dedicated apparatus on the skin surface of a region to be tested, and scanning more than one time in which the resolution of the apparatus is 1-32 cm?1 and the range of the spectrum is 800-4000 cm?1. It is possible to detect changes in molecular structures of living biological tissues in the early stages of cancer, and testees will not feel uncomfortable during testing. The method is easy to operate, quick, accurate, and it doesn't harm the body.
