    • Disclosed herein is a method for producing a polyurethane foam dressing that protects injuries such as wounds or burns and is useful for wound healing. More particularly, the present invention provides a method for manufacturing a polyurethane foam dressing with remarkably improved productivity and processing efficiency, which can improve physical properties of the polyurethane foam dressing. The method comprises: preparing a moisture permeable waterproof polyurethane film layer; preparing a polyurethane prepolymer; preparing a polyurethane foaming mixture; obtaining a tacky gel type polyurethane foam layer; laminating the tacky gel type polyurethane foam layer on the polyurethane film layer; and winding the produced polyurethane foam dressing in a roll form and then ageing the foam dressing. The method further includes, impregnating the polyurethane foam with a moisturizer and drying the foam and, then, treating the foam with oxygen plasma to modify a surface of the foam dressing, thereby improving absorption rate of the foam dressing. The method of the present invention has advantages such as remarkably improved productivity and processing efficiency allowing mass production of foam dressings, thereby considerably reducing production costs and enabling supply of low cost foam dressings with improved physical properties.

    • A liquid nitrogen and electric motor car using a heater pump is provided to drive a car fast by generating huge pressure by using a low boiling point of liquid nitrogen. A liquid nitrogen and electric motor car using a heater pump comprises a liquid nitrogen tank(1), a waste heat recovery unit, an external air heat exchanger(4), a liquid heat exchanger(8), a heat pump, and a condenser. The liquid nitrogen tank compresses and transfers liquid nitrogen to the waste recovery unit by using a nitrogen pump(2). The waste heat recovery unit evaporates the liquid nitrogen. The external air heat exchanger re-evaporates the liquid nitrogen by using a fan. Nitrogen gas is injected to the liquid heat exchanger. The condenser and the tank are filled with an antifreezing solution. The liquid heat exchanger heats the condenser and the tank by using the heat pump and liquefies a refrigerant.

    • A gear expander turbine is provided to increase the rotation speed by simultaneously rotating inner and outer gears and to achieve high output by increasing the volume between the gears. A gear expander turbine includes an inner gear(1) and an outer gear(2). The inner and outer gears are simultaneously rotated. The number of teeth of the inner gear is two, which is less than that of the outer gear by one to form a volume. A sealing plate is engaged with the outer gear by a bolt at a rear surface of the inner gear to maintain a sealing. A power transmission shaft is connected to the sealing plate to transmit a power to outside. Gas is introduced or discharged through a suction port(4) or a discharge port(5) in order to generate the power.
