Abstract: An air blower is disclosed. An air blower according to an aspect of the present invention includes: a fan member rotatably provided to provide transfer force to fluid; a flow passage-forming member accommodating the fan member, having a space that communicates with the outside, and including an outer periphery that encompasses the fan member; a scroll unit rotatably accommodated in the space of the flow passage-forming member; and a housing, which communicates with the space of the flow passage-forming member and the outside, covers the space of the flow passage-forming member and the scroll part, and is coupled to the flow passage-forming member, wherein the scroll unit includes: a scroll motor fixedly coupled to the housing; a scroll body coupled to the scroll motor so as to rotate by means of the operation of the scroll motor; and a scroll opening penetrating the outer periphery of the scroll body so as to allow the space of the flow passage-forming member to communicate with the outside.

Abstract: A signal processing apparatus detects a phase difference between two signals by applying the Lissajous figure and compensates for an error between the signals by recognizing a pattern, thereby easily detecting the phase difference between the signals.

Abstract: A refrigerant composition according to embodiments of the present disclosure includes trifluoroiodomethane (R-131I), 1,1-difluoroethane (R-152a) and difluoromethane (R-32), wherein a content of the trifluoroiodomethane (R-131I) may be 20 to 60 wt. % based on a total weight of the refrigerant composition. Accordingly, environmental pollution caused by the refrigerant composition may be suppressed, and the cooling performance of the refrigerant composition may be improved.

Abstract: A display device includes: a substrate; a first electrode on the substrate; a bank layer on the first electrode; an organic light-emitting layer on the first electrode; a second electrode on the organic light-emitting layer and the bank layer; a high-refractive lens on the second electrode and having a refractive index higher than a refractive index of a material that overlaps the first electrode and contacts a side surface of the high-refractive lens; a display panel including an encapsulation member that is on the high-refractive lens; and an optical path adjustment film on the display panel. The optical path adjustment film includes a plurality of protruding patterns on the encapsulation member and a cover layer in spaces between adjacent protruding patterns from among the plurality of protruding patterns. A refractive index of each of the protruding patterns is smaller than a refractive index of the cover layer.

Abstract: A display device may include a substrate including a display area and a non-display area; and a plurality of pixels disposed in the display area, the plurality of pixels each including an emission area and a non-emission area. Each of the plurality of pixels may include at least one light emitting element in the emission area; a first pixel electrode and a second pixel electrode electrically connected to the at least one light emitting element; a bank including a first opening corresponding to the emission area; a color conversion layer disposed in the emission area to correspond to the at least one light emitting element; a barrier layer disposed on the bank and the color conversion layer; and a low refractive layer disposed on the barrier layer. The barrier layer may include silicon oxide (SiOx) having cured polysilazane.

Abstract: An apparatus is disclosed which can shape fruits and root and tuberous vegetables. The shaping apparatus is operated in such a manner that: when root and tuberous vegetable or fruit is placed in a cutting blade case and rotated, the object is spirally tracked and the spirally tracked object is removed from the lower side of the cutting blade case, so that the spirally tracked object is picked up by an additional stick and then ornamented into various forms. The shaping apparatus allows fruits and root and tuberous vegetables to be easily treated in a variety of ways, as per the second process, thereby enhancing the product value of processed foodstuffs produced from the first process.

Abstract: A universal serial bus (USB) type wireless data card is used for wireless communication in a multi-in/multi-out (MIMO) environment. The USB type wireless data card includes a card body. A USB connector is installed at a first end of the card body and is connectable to a USB port of an electronic device. An antenna part includes a first antenna and a second antenna rotatable with respect to the card body to be spaced apart from the electronic device.
