  • Patent number: 11131874
    Abstract: An optical film includes a first pattern layer including a first base portion and first protruding portions disposed on the first base portion to be spaced apart from each other and having a first refractive index and a second pattern layer disposed on the first pattern layer and having a second refractive index. Each of the first protruding portions includes a first sub-protruding portion having a first width in a cross-section perpendicular to the first base portion, a second sub-protruding portion disposed between the first base portion and the first sub-protruding portion and having a width that increases from the first sub-protruding portion to the first base portion, and a third sub-protruding portion disposed on the first sub-protruding portion and having a width that decreases as a distance from the first sub-protruding portion increases.

  • Publication number: 20130032124
    Abstract: A fuel circulation system for a dimethyl-ether fuel vehicle may include a fuel tank storing a fuel, a fuel supply line connected to the fuel tank, a fuel supply pump disposed in the fuel supply line and supplying the fuel to a fuel injection system under pressure, a common rail maintaining the pressure of the fuel pressurized from the fuel supply pump, the fuel injection system injecting the fuel supplied from the common rail, a fuel return line fluid-communicating with and diverging from the fuel injection system and/or the common rail to collect remaining fuel of the fuel, and a fuel cooling system disposed on the fuel return line such that a return fuel returned from the fuel injection system and/or the common rail passes therethrough, wherein the fuel cooling system may be disposed close to a heater core to exchange a heat of the return fuel.
