A fuel gas supply system of a vessel, such as an LNG carrier, is provided for supplying fuel gas to a high-pressure gas injection engine of an LNG carrier, wherein LNG is extracted from an LNG storage tank of the LNG carrier, compressed at a high pressure, gasified, and then supplied to the high-pressure gas injection engine. In one embodiment, the system includes a boil-off gas reliquefaction apparatus for reliquefying boil-off gas generated in the LNG tank.
摘要:
A light emission device for improving high voltage stability and a display device using the same as a light source includes first and second substrates facing each other, an electron emission unit located on one side of the first substrate and including a plurality of electron emission elements, and a light emission unit located on one side of the second substrate and emitting a visible light. Each of the electron emission elements includes first electrodes spaced apart from each other by a predetermined interval along a first direction of the first substrate, second electrodes arranged between the first electrodes along the first direction, and first electron emission regions electrically connected to the first electrodes and formed at a predetermined height lower than that of the first electrodes.

A roller type developing apparatus for a cycolor type color video printer. A pair of said plates are mounted on a base of the color video printer and spaced apart from each other, the side plates each is provided with a vertical mounting hole. The upper and lower pressing rollers each is rotatably supported between the side plates, and provided with a clearance for allowing the cylith film and the receiver paper to pass therethrough at the same time. The upper and lower support bearings are vertically mounted in each mounting hole of the side plate and connected to respective end shafts of the upper and lower pressing rollers, respectively, and each is adapted for supporting the upper and lower pressing rollers. The pressure controlling member is adapted for controlling the clearance in order to control the pressure for the upper and lower pressing rollers. The present invention provides a roller type developing apparatus which is provided with the clearance, thereby preventing the deflection of the pressing rollers and the jamming the cycolor paper, and providing the equality of the coloring and the compactness of the color video printer.
