20140053600 | SYSTEM FOR SUPPLYING FUEL TO HIGH-PRESSURE NATURAL GAS INJECTION ENGINE HAVING EXCESS EVAPORATION GAS CONSUMPTION MEANS - Provided is a fuel supply system for a high-pressure natural gas injection engine. The fuel supply system includes: a BOG compression unit configured to receive BOG, which is generated in a storage tank, from the storage tank and compress the received BOG to a pressure of 12 to 45 bara; a reliquefaction apparatus configured to receive and liquefy the BOG compressed by the BOG compression unit; a high-pressure pump configured to compress the BOG liquefied by the reliquefaction apparatus; a high-pressure gasifier configured to gasify the BOG compressed by the high-pressure pump and supply the gasified BOG to the high-pressure natural gas injection engine; and an excess BOG consumption unit configured to consume excess BOG corresponding to a difference between an amount of BOG generated in the storage tank and an amount of BOG required as fuel for the high-pressure natural gas injection engine. | 02-27-2014 |
20140060110 | FUEL SUPPLY SYSTEM FOR MARINE STRUCTURE HAVING RELIQUEFACTION APPARATUS AND HIGH-PRESSURE NATURAL GAS INJECTION ENGINE - Provided is a fuel supply system for a marine structure. The fuel supply system includes a BOG compression unit configured to receive and compress BOG generated in a storage tank, a reliquefaction apparatus configured to receive and liquefy the BOG compressed by the BOG compression unit, a high-pressure pump configured to compress the liquefied BOG generated by the reliquefaction apparatus, and a high-pressure gasifier configured to gasify the liquefied BOG compressed by the high-pressure pump. The fuel supply system includes a recondenser installed at an upstream side of the high-pressure pump and configured to recondense a portion or all of the generated BOG by using liquefied gas received from the storage tank. The BOG compression unit compresses BOG to a pressure of about 12 to 45 bara such that the BOG is liquefied under the compression pressure of the BOG compression unit. | 03-06-2014 |

20140290279 | LIQUEFIED GAS TREATMENT SYSTEM FOR VESSEL - A liquefied gas treatment system includes: a first stream of boil-off gas, which is generated from the liquefied natural gas in the cargo tank and is discharged from the cargo tank; a second stream of the boil-off gas, which is supplied as fuel to the engine in the first stream; and a third stream of the boil-off gas, which is not supplied to the engine in the first stream. The first stream is compressed in a compressor and is then branched into the second stream and the third stream. The third stream is liquefied by exchanging heat with the first stream in a heat exchanger, so that the boil-off gas is treated without employing a reliquefaction apparatus using a separate refrigerant. | 10-02-2014 |

20100283708 | EXTENDABLE SWIVEL ANTENNA - Disclosed is an extendable swivel antenna, specifically a swivel antenna with enhanced durability, which can prevent deformation of a hinge unit and an outermost antenna covering the hinge unit. The swivel antenna includes: a power feeding unit | 11-11-2010 |
20110227802 | LOG PERIODIC ANTENNA AND MANUFACTURING METHOD THEREOF - Disclosed is a log periodic antenna and a manufacturing method thereof. In the log periodic antenna, antenna elements are attached to an antenna body to thereby simplify a structure of the antenna, the antenna can be manufactured in various designs without restriction to the configuration of the antenna, and the number of contacting points between the antenna element and a feeder is minimized to thereby simplify the manufacturing process. By the antenna, it is possible to produce the log periodic antenna of the simple structure and of various designs without the restriction to the antenna configuration by attaching the signal pattern and ground pattern to the pattern receiving surface. | 09-22-2011 |
20120086674 | TOUCH SCREEN OPERATING PEN - A touch screen operating pen, by inserting a pen rubber supporter supporting the inside in the pen rubber section which touches and drags the touch panel/screen, which prevents the pen rubber section from being slipped to one side direction when the pen rubber section drags on the touch screen, and by securing a wider area where the pen rubber section contacts with the touch screen, which can touch and drag the touch panel/screen with a small power, and can effectively perform the touch and drag action while the pen rubber section contacts with the touch panel/screen. In addition, by interposing the plate spring having elastic force between the touch pen body and the pen rubber section which touches the touch panel/screen, it improves the click feeling and greatly raises the success rates of touch and click. Furthermore it can be used with the removable antenna or the constant pressure type touch pen. | 04-12-2012 |
