The unconstrained vibration damping metal sheet of the present invention comprises: a metal sheet; an organic-inorganic pretreatment layer containing an acrylic resin formed on the metal sheet; and a foam resin layer formed on the pretreatment layer, the foam resin layer containing, based on weight % thereof, a thermoplastic polyvinyl chloride resin: 40-80%, a plasticizer: 5-40%, a foaming agent: 0.1-10%, an oxide-based crosslinker: 1-4%, and spherical silica: 1-10%.

Abstract: Provided are a constrained-type vibration-damping metal sheet having foam pores and a method for manufacturing same. The constrained-type vibration-damping metal sheet of the present invention comprises: a lower metal sheet; a foam resin film bonded to the lower metal sheet; and an upper metal sheet bonded to the foam resin film, wherein the foam resin film has foam pores comprising, by wt % of itself, 85-95% of a thermoplastic polyethylene resin having a number average molecular weight of 8000-12000, 0.1-1% of stearic acid, 1-5% of a styrene-ethylene-butadiene-styrene (SEBS) resin, 0.5-5% of a foaming agent, 1-4% of a dicumyl peroxide crosslinking agent, and 0.5-2% of ZnO foaming aid.

Abstract: The present disclosure relates to an electronic device for capturing a reproduction speed changing video which is reproducible in all devices without additional encoding, and a control method thereof. The method of controlling an electronic device for capturing a video includes generating, at a first frame rate, a first frame group obtained by photographing a subject, receiving an input for changing a reproduction speed, and determining a second frame rate based on the changed reproduction speed. The method further includes generating, at the second frame rate, a second frame group obtained by photographing the subject, and generating a single video file by encoding the first frame group and the second frame group based on the first frame rate.

Abstract: A washing machine includes a cabinet, a tub provided inside the cabinet to store wash water therein, a drum rotatably provided inside the tub, and a balancer comprising an upper side surface covering an outer surface of a bottom of the drum and a lower side surface formed at one side of the upper side surface in a planar shape while facing an inner surface of a bottom of the tub. The balancer is configured to counterbalance an unbalanced load of the drum, thereby saving energy and enhancing balancing efficiency.

Abstract: A washing machine including a filter device, a support, or an auxiliary damper, using pressure of water supplied thereto. The washing machine includes a casing, a reservoir installed inside the casing, a water supply tube connected to an upper portion of the reservoir such that wash water is supplied through the water supply tube, a drainage tube connected to a lower portion of the reservoir such that wash water is discharged through the drainage tube, and a filter device which allows wash water to be moved and eliminates foreign substances from the wash water at one side of the reservoir using pressure of the wash water supplied through the water supply tube. It may be possible to eliminate foreign substances from laundry using pressure of water supplied according to progress of operation of the washing machine without provision of additional power.

Abstract: An air blowing unit of an air conditioner includes a housing to guide suction and discharge of air, a centrifugal fan positioned inside the housing, and a motor to drive the centrifugal fan. The centrifugal fan includes a base coupled to a motor shaft coupled to the motor, a plurality of blades disposed spaced apart from each other in a circumferential direction of the base to guide air introduced in an axial direction of the base to the circumferential direction, a leading edge provided to the blades and arranged close to the motor shaft, a trailing edge provided to the blades and facing in an outer circumferential direction of the base, and at least one first blade of the blades, the leading edge of the first blade being shorter than the leading edge of the other blades.

Abstract: A washing machine includes a cabinet; a tub which is disposed in the cabinet and in which washing water is stored; a drain hose that guides the washing water in the tub toward an outer side of the cabinet; and a siphonage prevention unit disposed on the drain hose, wherein the siphonage prevention unit includes: a connection pipe having a connection flow path that communicates with the drain hose; an air pipe having an air flow path that communicates with the connection flow path; and a protrusion that is disposed adjacent to a communication portion in which the connection flow path and the air flow path communicate with each other and that protrudes from an inner side surface of the connection pipe. Through this configuration, a siphonage phenomenon in the drain hose can be prevented.
