Abstract:
PURPOSE: A computer input and output control method and an apparatus thereof are provided to minimize restriction in a hardware module size and to maximize flexible management of various requirements, thereby reducing design costs. CONSTITUTION: A computer input and output control method applying VPX(Versatile Performance Switching) bus standard and FPGA(Field Programmable Gate Array) IP(Intellectual Property) core technology includes following steps. A single board computer receives power through a backplane board(S600). The single board computer checks whether the single board computer communicates with a different module or not through an input and output module(S610). The single board computer communicates with the different module(S620). The backplane board includes a bus based on VPX standard for high-speed data processing. The input and output module loads an IP core in an FPGA chip. [Reference numerals] (AA) Start; (BB) End; (S600) Step of receiving power through a backplane board; (S610) Step of checking whether communicating with a different module or not; (S620) Step of communicating with the different module after checking the communication with the different module through an input and output module
Abstract:
PURPOSE: A manufacturing method of a titanium dioxide nanowhisker using a cycling heat treatment is provided to efficiently manufacture titanium dioxide whiskers by a cycling heat treatment. CONSTITUTION: A manufacturing method of a titanium dioxide nanowhisker using a cycling heat treatment comprises a step of first heating a sintered material of titanium alloy to 660-900>= in a tube furnace; a step of exposing the sintered body at room temperature for a first quick oxidation; a step of second heating the sintered body to 660-900>=; a step of exposing the sintered body at room temperature for a second quick oxidation; and a step of third heating a sintered material of titanium alloy to 660-900>=. The titanium alloy is one selected from Ti-xAl and Ti-xAl-yV. The sum of the first heating and second heating time is 20-60 minutes. The third heating time is 60-120 minutes.
