| 20120073875 | SLIDE-TYPE CORE RETAINER FOR SAMPLE COLLECTOR - A slide-type core retainer for a sample collector including a sampler tube driven into a sea floor. The slide-type core retainer includes a catcher holder detachably coupled to a tip end of the sampler tube; a catcher installed on an inner peripheral surface of a tip end of the catcher holder and configured to allow sediment introduction into the sampler tube and preventing sediment from being lost using resiliency. A control member slidably installed inside the catcher holder controls opening and closing of the catcher. The control member is coupled to the catcher before sample collection so that the catcher remains opened. The control member slides into an inner side of the catcher holder while being separated from the catcher by the resistance of the solid sediment such that the catcher is closed, when resistance is generated by solid sediment after the sampler tube is driven into the sediment. | 03-29-2012 |

| 20100072752 | POWER GENERATION SYSTEM USING HELICAL TURBINE - Disclosed is a helical turbine power generation system for generating electricity by using a helical turbine and an overload prevention generator, the system including: a helical turbine rotatably provided in a frame so as to continuously generate rotation force under unidirectional or multidirectional fluid flow; a step-up gear for increasing a rotational velocity of the helical turbine up to a level required for generating electricity; and an overload prevention generator for generating electricity by using the rotational velocity transferred from the step-up gear, and for preventing overload caused by a sudden increase in a rotational velocity. Therefore, it is possible to reduce equipment costs and to prevent environmental pollution. | 03-25-2010 |
| 20100066091 | POWER GENERATION SYSTEM USING HELICAL TURBINE - Disclosed is a helical turbine power generation system for generating electricity by using a helical turbine and a synchronous generator, the system including: a helical turbine rotatably provided in a frame so as to continuously generate rotation force under unidirectional or multidirectional fluid flow; a step-up gear for increasing a rotational velocity of the helical turbine up to a level required for generating electricity; a fluid coupling for preventing the rotational velocity increased by the step-up gear from increasing above a required velocity at a temporarily high rate of fluid flow; and a synchronous generator for generating electricity by using the rotational velocity transferred from the fluid coupling. Therefore, it is possible to reduce equipment costs and to prevent environmental pollution. | 03-18-2010 |
| 20100041926 | LIQUEFIED EXTRACT OF MARINE ALGAE FOR PRODUCING BIO-ETHANOL UNDER HIGH PRESSURE AND METHOD FOR PRODUCING THE SAME - A high-pressure liquefied extract of marine algae for producing bioethanol and a method of producing the liquid extract from marine algae under high pressure, and a method of producing the bioethanol from the high-pressure liquid extract by fermentation with yeast are disclosed. According to the production method of bioethanol using marine algae, the high-pressure liquefied extract can be obtained in high yield and fermentation time can be also reduced. Consequently, the yield of bioethanol is increased. Furthermore, the method gives economical and environmentally friendly values from natural marine algae. | 02-18-2010 |
