  • By growing the capacity of container in the world, main container terminal in countries introduces the automated container equipments and try to improve the productivity for handling the container. ARMC(Automated Rail Mounted Crane) is installed in automated container terminal and expected the high efficiency of productivity by using minimum-time control method. However recently by the GREEN Port policy, high energy efficiency method for container equipments is importance issue in ports. In this paper, the 3-dimensional modelling of AMRC is discussed and the acceleration characteristics for ARMC is analyzed By using the results of this paper, the advanced controller for the crane will be developed in future.

  • Recently, As increasing cleanroom size, Stocker system is trending the large size and long distance for LCD material transfer system In order to rise a rate of production, the manufacturer are on the decrease of total tact time with Stocker system And the manufacturer are requested to high speed of next generation Stocker system Also manufacturers for the high oil prices through energy-saving conservation to minimize plant operating costs are required. Therefore, this paper propose optimal design of high efficiency Contactless Power Supply(CPS) system about high speed and energy savings of next generation Stocker system This paper proposes CPS system is applied in the long distance and straight section with Stocker system for energy savings. The test results of input!output characteristic and efficiency of CPS system on operating pattern of Stocker system were analyzed, and proved the applicability on commercial use.

  • This paper introduces the design concepts and characteristics of WinDS3000$^{TM}$ which is a trade mark of Doosan's 3MW offshore/onshore wind turbine. WinDS3000$^{TM}$ has been designed in consideration of high RAMS (Reliability, Availability, Maintainability and Serviceability) and cost effectiveness for the TC Ia condition in GL guideline. An integrated drive train design with an innovative three-stage gearbox has been introduced to minimize nacelle weight of the wind turbine and to enhance a high reliability for transmission. A permanent magnet generator with full converter system has been introduced to get higher efficiency in part load operation, and grid friendliness use of 50 Hz and 60 Hz grid. A pitch regulated variable speed power control with individual pitch system has been introduced to regulate rotor torque while generator reaction torque can be adjusted almost instantaneously by the associated power electronics. An individual pitch control system has been introduced to reduce fatigue loads of blade and system. The wind turbine has been also equipped with condition monitoring and diagnostic systems in order to meet maintainability requirements. And internal maintenance crane in nacelle has been developed. As a result, the maintenance cost was dramatically reduced and maintenance convenience also enhanced in offshore condition.

  • PFC(Perfluorocarbon) decontamination process is one of best methods to remove hot particulate adhered on the inner surface of hot cell and surface of equipment in hot cell. It was necessary to develop a filtration equipment to reuse the PFC waste solution generated on PFC decontamination due to the high cost of PFC solution and for minimization of the volume of second waste solution. The filtration equipment was developed to remove hot particulate in PFC waste solution. It was made suitable size and weight in consideration of hot cell gate and crane. And it has wheels for easy movement. Flux of the filtration equipment decreased with particulate concentration increase. It consists of pre-filter($1.4{\mu}m$) and final-filter($0.2{\mu}m$) for protection of the flux decrease along filtration time. It treatment capacity of waste solution is 0.2 L/min.
