A curved haptic actuator according to an embodiment may comprise: a housing having a receiving space and having a shape where the receiving space and an outer appearance thereof are bent outward; a vibration unit disposed in the receiving space, being movable along the longitudinal direction of the housing, and having a shape bent upward; elastic bodies connected to an inner wall of the housing and both sides of the vibration unit; and a magnetic field generation unit which is installed on the inner wall of the housing and generates a magnetic field and applies the magnetic field to the vibration unit.

Curved haptic actuator and wearable device comprising same

The coating composition of the present application has excellent antistatic properties and thus can be used as an antistatic hard coating film. The coating composition of the present application may comprise a salt based on a polyoxometalate anion and a radically polymerizable cation, and a radically polymerizable binder to form an antistatic hard coating film having excellent antistatic property, abrasion resistance and moist-heat resistance. Such a film can be used for an optical laminate and a display device, and the like.

Coating composition

A composite power generating device of the present invention includes an engine (), a first flow line (), a turbocharger (), a second flow line (), a third flow line (), a compressor (), a first medium line (), a medium turbine (), a second medium line (), a working medium cooler (), a recuperator (), a power generating unit (), a cross-line (), a first heat exchanger (), a second heat exchanger (), and a third heat exchanger ().

Combined power generation apparatus

A control method of a waste heat recover device, the control method includes measuring a first state value of an organic refrigerant discharged from an organic refrigerant evaporator by a first state value measuring unit; determining whether the first state value measured by the first state value measuring unit deviates from a first set range and controlling a flow rate of an organic refrigerant introduced into the organic refrigerant evaporator by a first organic refrigerant variable valve when it is determined that the first state value deviates from the first set range.

Waste heat recovery apparatus and control method therefor

A coating composition having excellent anti-static properties and suitable for use as anti-static hard coating films. The coating composition comprises a radical polymerizable binder and a salt based on an anion including a cage-shaped frame. The anti-static hard coating film formed using the coating composition has excellent anti-static properties, abrasion resistance and moist heat resistance. Such film may be used for an optical laminate a display device, and the like.

Coating composition including a salt having a silsesquioxane anion
