摘要： An apparatus and a method for applying high voltage with high frequency. The apparatus includes a power generator for generating electric power with predetermined frequency, a voltage transformer receiving the electric power generated by the power generator, amplifying voltage of the electric power received, and applying the amplified voltage to a load, and an impedance matcher connected between the power generator and the voltage transformer to match impedances of the power generator and the voltage transformer to thereby transmit the electric power to the voltage transformer. High voltage with high frequency is obtained by transmitting the electric power generated from the power generator to the load without reflecting loss while conducting an impedance matching, and amplifying the voltage applied to the load using the coupled inductor and LC resonance.

摘要： An apparatus for maintaining the freshness of foods is provided. The apparatus comprises first and second electrodes spaced oppositely to a predetermined distance, a voltage generator unit applying voltage between the first electrode and the second electrode, heat transfer means connected to the first electrode or the second electrode to absorb heat from the space between the first electrode and the second electrode, and a temperature control unit controlling the heat transfer means such that the space between the first electrode and the second electrode is of predetermined temperature, whereby the heat transfer means is connected to the electrode for voltage application, so that both the application of electric field and the temperature regulation are advantageously obtained using a single electrode without installing a separate device for temperature regulation.

摘要： The present invention relates to a 3D printer using a metal alloy filament, wherein the 3D printer introduces a metal alloy filament (650) through a nozzle (610) formed inside an induction heating coil (620), melts and extrudes the filament, and laminates the filament three-dimensionally inside a chamber (500) heated to a similar temperature. The present invention forcibly introduces a metal alloy filament in a nozzle, heated by an induction heating coil which circularly encloses the exterior of the nozzle and forms a cooling passage therein, by means of a transfer gear connected to a transfer motor. A 3D printer for a metal alloy filament is provided in which, in order to prevent the oxidation of a metal alloy laminate (520), an inert gas is introduced, the outside and heat and air are blocked, and a metal alloy filament (650) that is melted in a nozzle and extruded is laminated one layer at a time on a floor plate (510) installed inside a heated chamber (500) and moving three-dimensionally with respect to the nozzle, in order to firmly attach the filament having little deformation.
