Disclosed are a refractive optical screen and a floating hologram system using the same. The refractive optical screen is a refractive optical screen which refracts incident light beams and adjusts a travelling direction of the light beams, and includes a prism array in which a plurality of prisms refracting one or more light beams toward a viewing direction of a viewer located at the front side of the refractive optical screen is arranged in a line, and one or more virtual images generated by the one or more refracted light beams simultaneously form a floating hologram arranged in the viewing direction.

A hydraulic engine mount is provided in which related components out of two or more internal parts are coupled to reduce the number of components and to prevent oil leakage occurring due to coupling of the parts. The hydraulic engine mount includes a core that has a central bolt inserted into a central portion thereof, a rubber member formed on an outer circumferential surface of the core, upper and lower fluid chambers to seal a fluid therein. A diaphragm is disposed at a lower end of the lower fluid chamber and an orifice assembly divides the upper and lower fluid chambers from each other and has nozzle upper and lower plates. A nozzle upper plate-combined case that has a flow path is formed integrally with a lower part of the rubber member, and a lower part of the flow path is hermetically sealed by the nozzle lower plate.
