Abstract: The present invention relates to an amorphous alloy having low frictional resistance and capable of improving abrasion resistance, a target made of the amorphous alloy, and a compressor comprising a layer of the amorphous alloy as a coating layer. According to the present invention, it is possible to secure high hardness and a low elastic modulus of the coating layer by controlling a microstructure having an amorphous phase as a primary phase by using Ti-based three-component to five-component amorphous alloys. As a result, it is possible to prevent the coating layer from being peeled off from a matrix or destroyed, and thus it is possible to achieve the effect of improving reliability or durability of a mechanical apparatus such as a compressor

Abstract: The present invention relates to a cooking appliance. The cooking appliance according to the present invention may have a cavity (S) formed inside cases (100 and 200), and a first heat source module (400) which emits microwaves may be disposed on the side surface of the cases (100 and 200). A second heat source module (600) which generates radiant heat may be disposed on the upper portion of the cases (100 and 200). In addition, it is possible to elevate the second heat source module (600), and whether the first heat source module (400) operates may be determined according to whether the second heat source module (600) is elevated.

Abstract: A cooking appliance is proposed. A casing (100, 200) may have a cavity (S) therein, and of which a front surface may have an air inlet part (242) and an air outlet part (243) at different heights. A plurality of heat sources modules may be arranged at different surfaces of the casing (100,200). A this point, a cooling fan module (810, 850) may be arranged in a first electric chamber (ES1) provided behind the air inlet part (242), and transfer suctioned air into a second electric chamber (ES2) provided behind the air outlet part (243). Accordingly, the air suctioned by the cooling fan module (810, 850) may be discharged after circulating to through the first electric chamber (ES1) and the second electric chamber (ES2), and in this process, the plurality of heat sources may be cooled.
