摘要:
A method for filament winding a pressure vessel having at both end domes thereof holes of different diameters and preferably used for a high pressure combustor of a rocket engine. The present method comprises first and second winding processes. In the first process, the first mandrel on which the winding band is wound is provided with a jig which makes the outer diameters of the opposite bosses of the mandrel be equal to each other and is removed after hardening process. In the second process, the winding band is again wound on the second mandrel comprising a first body obtained from the first process and provided with a jig which makes the outer diameters of the opposite bosses of the second mandrel be equal to each other and is removed after hardening process. In result, the winding band is always wound on the mandrel along straight winding passages in the two winding processes because the outer diameters of the opposite bosses of each mandrel are equal to each other, thereby causing the pressure vessel manufactured by the present method to have a good structural strength efficiently enduring high pressure.

The system and method of the present application is a microfluidic array system for biological, chemical and biochemical assessments including a microfluidic chip for reaction assays, wherein the microfluidic chip includes a control layer and a fluidic layer, wherein the control layer is pressurized through pneumatic or hydraulic means in order to control the flow of the reagents in the fluidic layer. The system and method of the present application further includes a method of fabricating such a microfluidic chip, and further a method for operating the same. Lastly, the system and method of the present application further includes a system for operating and analyzing the microfluidic array including a pressure source, a fluidic source, a biochip reader, and a processor configured to control the same.
摘要:
Disclosed is a copolymer coordination compound including two or more kinds of complexes, and a method of preparing the same. Herein, each of the complexes includes an organic ligand and a metal ion, and the two or more kinds of complexes are arranged in a line in a regular or irregular order, and are coordinated to each other. Also, the disclosed copolymer coordination compound functions as a gelator in a solvent, and is formed into a gel.
