Abstract: The present disclosure relates to a cleaning module-integrated beverage dispensing head, capable of selectively providing a cleaning function in addition to a conventional beverage dispensing function. A cleaning module-integrated beverage dispensing head includes a gas distributor (200) outputting a gas flowed in, and a pulse generator (100) receiving a supply of the gas supplied via a hose (300). The gas distributor (200) includes a first gas outlet (220) discharging the gas to the pulse generator (100), a second gas outlet (230) discharging the gas to a container (C) for storing liquid, an internal structure (200a) that is rotatable, and an external structure (200b) that is coupled to the internal structure (200a), to control rotation of the internal structure (200a). Whether or not to supply the gas to the pulse generator (100) through the first gas outlet (220) is determined according to whether or not the internal structure (200a) rotates.

Abstract: A reduced iron production method using an electrowinning method and reduced iron is provided. The method includes, preparing a mixture by mixing, a solid electrolyte containing sodium peroxide (Na2O2) and boron oxide (B2O3), with iron oxide (Fe2O3); and putting the mixture in an electrowinning device provided with an anode and an insoluble cathode and heating to form a molten oxide and then applying a voltage to the anode and the cathode to form iron on the cathode. Therefore, by reducing iron oxide through an electrowinning method, a reduced iron in a pure iron state can be obtained. Although it is very difficult to obtain pure iron by refining an iron ore, by using the electrowinning method in which the composition of an electrolyte is controlled and electrolysis conditions are controlled, reduced iron that is pure can be obtained.

Abstract: The present disclosure relates to a method for preparing titanium by using electrowinning and, more specifically, to a method for preparing titanium by using electrowinning, comprising the steps of: preparing a mixture by mixing a solid electrolyte, which contains an oxide of a Group 1 element and boron oxide, with titanium dioxide; and forming a molten oxide from the mixture by putting the mixture in an electrowinning apparatus comprising an anode and an insoluble cathode and heating the same, and then forming titanium on the cathode by applying voltage to the anode and the cathode.

Abstract: A cleaning apparatus using a gas-mixed liquid includes a first inlet port into which a liquid supplied from the outside is introduced, a second inlet port into which a gas to be mixed with the liquid introduced from the first inlet port is introduced, a mixing chamber in which the liquid introduced from the first inlet port and the gas introduced from the second inlet port are mixed with each other, and an outlet port through which the liquid mixed with the gas in the mixing chamber is discharged. According to the present invention, it is possible to efficiently remove slime such as scale generated in a variety of industrial conduits in which liquids flow, and germs, etc. deposited in various conduits.

Abstract: A method of manufacturing an optical waveguide is disclosed. The method in accordance with an embodiment of the present invention includes providing a carrier, fixing a base substrate to the carrier by using a first insulation layer such that the base substrate is directly stacked on the carrier, stacking an optical waveguide layer on at least one of the base substrate and the first insulation layer, and severing the base substrate such that the base substrate and the optical waveguide layer are separated from the carrier. Accordingly, the optical waveguide layer can be formed with a uniform thickness since wrinkles in the base substrate supporting the optical waveguide layer are prevented from forming during the manufacturing process.
