Abstract: This specification relates to a decoration member including: a substrate; and a decoration layer provided on the substrate in which there are one or more combinations of viewing angles ? and ? in which a contrast parameter Cn represented by Equation 1 is 0.1 or more.

Abstract: A wave power generator includes a frame unit mounted on the shore, an electric generator unit generating electricity by means of a rotating motion of a rotor, a drive unit having a plurality of wave-power receiving bodies receiving the energy of a reciprocating horizontal motion of wave power and reciprocating between the sea-side and the land-side, wherein the wave-power receiving bodies are mounted in the frame unit in a stepwise manner in a plan view so that the wave-power receiving bodies do not meet the waves at the same time, and a power transmission unit mounted in the frame unit to convert a linear motion of the drive unit into a rotating motion and transmit the rotating motion to the rotor of the generator unit.

Abstract: The present invention provides an anti-fog instrument for swimming goggles including: a main body (10) that is made of a transparent synthetic resin to have a shape corresponding to a see-through window of the swimming goggles; an anti-fog layer (20) that is formed at the opposite side of the see-through window of the main body (10), by coating a material having an anti-fog function; an adhesive layer (30) that is formed at a side-facing the see-through window of the main body (10), by coating an adhesive material; a release paper (40) that is attached to the surface of the adhesive layer (30) to be easily detached; and a grip (50) that integrally protrudes from one side of the edge of the main body (10), in order to be replaced at any time while preventing fog when an anti-fog agent is not coated on a see-through window.
