  • Publication number: 20210318301
    Abstract: The present disclosure relates to an integrated immunodiagnostic fluorescence reader having a multiple diagnoses function, the reader being configured to identify and classify samples through barcodes that are allocated differently by diagnosis marker and adjust an optimum reaction time in a lateral flow method, and the present disclosure utilizes barcode information formed on a surface thereof that is the same as that of a fluorometric window of a diagnostic cartridge, so as to identify barcodes even if different kinds of diagnostic cartridges are inserted, thereby preventing errors, and, when a sample is loaded, senses a sample flowing to a development film so as to automatically calculate reaction time, and senses fluorescent information measured through the fluorometric window, thereby enabling simultaneous analysis of diagnostic markers or types of samples and the like.

  • Publication number: 20080216604
    Abstract: The present invention relates to a method for manufacturing the nanostructured powder by a wire explosion in liquid and a device for manufacturing the same. To be more specific, the object of the invention is to provide a method for manufacturing the nanostructured powder by a wire explosion in liquid and a device for manufacturing the same, in which, a metal wire (18) is vaporized in liquid (14) by generating an electrical explosion using the same principle al in gas, with the characteristic of pulsed power, even though the liquid (14) with a low conductivity is used, and the nanostructured powder of a metal wire (18) is produced in the space made by the volume expansion of vaporized vapour, all of which was performed with an understanding that electrical explosion is not so different in principle weather in gas or in liquid.

  • Patent number: 6600123
    Abstract: A rotary arc gap (RAG) switch capable of handling large amounts of current flow is disclosed. The circular electrodes of the switch incorporate the use of a high-resistance material placed in a gap in the electrodes. The absence of an air gap in the electrodes reduces wear and broadening at the edges of the gap and thus improves the life span of the switch. Further disclosed is the use of a dual trigger mechanism that also improves the life span of the electrodes and the triggers.

  • Patent number: 6357356
    Abstract: The present invention relates to an electric blasting device using aluminum foil, the objective of which lies in providing an economical and safe electric blasting device. In line with this objective; a portion of the outer conductor of the cable is removed, and the aluminum foil is inserted therein in order to electrically connect the inner and outer conductors. Between the aluminum foil and the inner conductor, water, an insulator, and a teflon tube are inserted. When pulse high-current is made to flow, the aluminum foil changes into the condition of plasma. The aluminum therefrom and water react to generate explosive power. The invention is economical in that it uses commercialized aluminum foil, in addition to having a short scattering distance of the fragments. It also allows a low-vibration blasting due to the short reaction time therein.
