Abstract:
PURPOSE: A collecting apparatus for an on-line electric vehicle is provided to prevent the rapid increase of electromagnetic field by regardless of power transmission from a collector to load. CONSTITUTION: A collecting apparatus for an on-line electric vehicle includes a collecting core(121), collecting coils(124.1, 124.2), and a shielding coil(125). The collecting core is arranged at the bottom side of the electric vehicle. The collecting core is formed into a plane shape. The collecting coils wind around the collecting core. The shielding coils wind around the collecting core to the opposite direction of the collecting coils in order to offset electromagnetic field.

PURPOSE: A mobile taxi rail system is provided to efficiently process cargo transport of a large container ship by enabling unloading of the large container ship even in small-scale harbors. CONSTITUTION: A mobile taxi rail system comprises a rail structure(100) which is installed in a water section, a fixing and supporting part(110) which fixes and supports the rail structure on the sea bottom, a traction train(200) which moves on the rail structure, and a mobile taxi(300) which is connected to the traction train to move along with the traction train. The rail structure comprises a rail beam(120) supported with the fixing and supporting part and a conveyer belt(140) moving along the rail beam.

PURPOSE: A current collecting device with a cancellation coil unit, a shielding system which selectively cancels an electromagnetic wave, an on-line electric vehicle with the current collecting device, and a method for cancelling the electromagnetic wave of an on-line electric vehicle are provided to analyze distribution of an unnecessary magnetic field occurring in an on-line electric vehicle, thereby completely cancelling the unnecessary magnetic field. CONSTITUTION: A magnetic field is induced by the flow of currents in a metallic bar(200). A current collecting unit(300) generates an induced current in a current collecting coil. A cancellation coil unit(400) is wound on a cancellation coil of each end of the metallic bar and cancels an electromagnetic wave occurring an on-line electric vehicle.

PURPOSE: A power supply device and a current collecting device for an electric vehicle are provided to form a power supply device of a Z shape and broaden an interval of gaps. CONSTITUTION: A Z shaped power supply device includes an ultra thin U-shaped core(311) and a dual rail power supply line(313,314). N polarity and S polarity of a magnet line are alternatively generated on each magnetic pole(312) of the power supply core. The power supply line is formed on the power supply core. The end part of the magnetic pole of the power supply core is completely buried in a road. The power supply device broadens an interval of a gap by a Z shaped structure. An interval between a road(320) and a current collecting device(315) of a vehicle increases by increasing an interval between magnetic poles.

PURPOSE: A transformable floating body is provided to maintain balance even in case of waves and weight variation of cargo loaded and unloaded. CONSTITUTION: A transformable floating body(100) comprises a hull(200), a submerging body(400), a connection part(300), and a drive unit. A platform is formed on the top of the hull. The submerging body is installed on the lower part of the hull. The connection part connects the submerging body and the hull. The drive unit drives the connection part and moves the submerging body connected to the connection part.
Abstract:
PURPOSE: A deck for a mobile harbor is provided to achieve reduced weight while securing flexural rigidity and compressive strength due to the sandwich structure in which polymer concrete cores are interposed between upper and lower plates. CONSTITUTION: A deck for a mobile harbor comprises an upper plate(10), a lower plate(20), and cores(30). The upper and the lower plate are made of steel and arranged at an interval. The cores, made of polymer concrete and having a hollow, are interposed between the upper and lower plates. The upper plate, the lower plate, and the core are bonded with adhesive layers(40). A plurality of strips are interposed between the upper plate, the lower plate and the cores to maintain the intervals.
Abstract:
PURPOSE: A car-to-car distance control method of a vehicle using traffic information offering system is provided to control the distance between vehicles by providing a service based on GPS. CONSTITUTION: A vehicles communication unit is installed in vehicles. A traffic information supply system communicates with the vehicle communication unit. The speed of a front vehicle and passing time of a current position are received from a communication unit(101) which is installed inside the road. The speed and current position of a user vehicle is received from a vehicle ahead of the user. The speed is adjusted to control the distance between the vehicles ahead of the user.
Abstract:
본 발명은 공간분할 다중 급집전 장치에 관한 것으로서, 더욱 상세하게는 차량, 수중 이동체 또는 로봇 등의 다양한 이동체에 대한 비접촉 방식의 급전 및 집전을 위해, 이동체의 진행방향을 따라 위상분할, 시간분할 또는 주파수분할 등에 의한 다중급전 방식의 선로로 구성하고 이로부터 전력을 공급받게 하는 공간분할 다중 급집전 장치에 관한 것이다. 본 발명에 의하면, I형 급전선로에 이동체 진행방향을 따라 이와 같은 공간분할 다중급전 방식을 적용함으로써 이동체의 진행방향으로 발생하는 규칙적인 출력전압의 변동을 최소화하여 거의 일정한 출력전압을 얻을 수 있으며, 2차측으로 전달되는 평균출력전력을 향상시키고, 인접한 자극 간에 발생하는 누설자속을 감소시켜 줌으로써 공극간격을 크게 한다.
