Abstract: An aquafarming system is provided that includes a cultivating barrel with a multi-floor net assembly for the cultivation of shellfish creatures or the like. In the aquafarming system, the use of the multi-floor net assembly allows an increased cultivating area such that the quantity of the shellfish creatures being cultivated can be increased to thereby increase the productivity. At the harvest time, the multi-floor net assembly can be lifted up so as to be separated from the cultivating barrel such that the cultivated shellfish creatures can be easily and conveniently collected to reduced labor time and cost.

Abstract: A method for the retraction of an explosive component from a high explosive, including the steps of loading a high explosive containing an explosive component into an striping down vessel; supplying a supercritical fluid to the striping down vessel; contacting the high explosive with the supercritical fluid at a temperature below the melting point of the explosive component and at a pressure sufficient to strip down the explosive component; and inducing a sonicating process on the striping down vessel simultaneously at a frequency of 2 MHz to 10 MHz.

Abstract: A method for the retraction of an explosive component from a high explosive, including the steps of loading a high explosive containing an explosive component into an extraction vessel. A supercritical fluid is supplied to the extraction vessel. The high explosive is contacting with the supercritical fluid at a temperature below the melting point of the explosive component and at a pressure sufficient to extract the explosive component.

Abstract: A recycling facility includes a receptacle for receiving the ammunition to be cleaned, a gas tank for receiving a pressurized gas and coupled to the receptacle, for supplying the pressurized gas to the receptacle, and a heater coupled between the gas tank and the receptacle, for preheating the pressurized gas before the pressurized gas flowing into the receptacle, and for melting and removing the TNT material from the ammunition. The receptacle includes a control valve coupled between the heater and the receptacle, and a control valve coupled between the heater and the gas tank. A collecting casing may be coupled to the receptacle, and coupled to the gas tank via a filter.

Abstract: An aging device includes an aging container having a chamber formed by a peripheral wall, a bottle received in the chamber of the aging container for receiving a liquid fermented product, and a vibrating device disposed in the aging container for applying a frequency to vibrate the liquid fermented product received in the bottle in order to oxidize the liquid fermented product. A vibrating medium is arranged between the bottle and the peripheral wall of the aging container. A heater may be disposed in the aging container for heating the bottle. The aging container includes an inner peripheral space formed in the peripheral wall for receiving the heater or a heat exchanging medium.

Abstract: The present invention provides a safe, efficient, nonpolluting and economical method for inactivating viruses in a biomaterial, characterized in comprising a step of introducing a high-pressure fluid into a container containing a biomaterial to be treated at a speed capable of forming non-turbulent flow with Reynold's number of 2000 or less, thereby inactivating viruses potentially existing in the biomaterial. The method in accordance with the present invention can inactivate or eliminate viruses in a heat-sensitive biomaterial such as proteinous material, without decreasing the biological activities of the biomaterial significantly.

Abstract: A motor system for a sewing machine includes a motor unit rotatable at a first rotation speed; a clutch unit with an output shaft capable of being coupled to or separated from the motor unit; a speed changing unit for switching the first rotation speed to a second rotation speed; a position control unit with a sliding disk being movable to a first position, a second position or a third position, making the sliding disk rotate at the second or first rotation speed or stopped; an auxiliary driving shaft for transmitting the rotation of the sliding disk to the output shaft; a first sensor for detecting the position of the clutch unit; and a second sensor for detecting the position of a sewing mechanism of the sewing machine. Thereby, a first speed control, a second speed control and a stopping position control can be achieved for the sewing mechanism.
