hightemperatures. For safety reasons, all activities in the RCA clean procedure should be performed in a Clean Station Work Area which is located under an exhaust fume hood.
[Figure 1] RCA cleaning
the RCA clean proceedure consists of the following steps
: Chemical Storage ⇒ Mix Organic Solution ⇒ Mix Ionic Solution ⇒ Mix HF Solution ⇒ Set-Up Bubbler Rinse
Figure 13 shows that cryo pump is cooling pump. It means this pump is cooling, liquefaction and store air, not pumping. Generally, it has 3 processes like condensation, absorption and trap at low temperature. The cooled air or molecules do not have any momentum so it is no possibility to heat any molecules. It means vacuum.
Cryo pump have High emission velocity and high emission capacity so it
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for hightemperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
연구배경 : 자동차는 인간에게 편리함을 주는 동시에 위험을 내포한다. 이는 사고를 유발할 수 있는 잠재요인들을 초기에 관리하여야만 안전운전이 가능함을 말해주고 있다.
자동차는 수 많은 부품들로 구성된 프로세스
자동차 안전관리에 소홀할 경우 다양한 문제 발생
