We can expect that after 2010, the cost of hydrogen as one ofthe resources should be lower than that of fossil fuel.

to make Ultra high vacuum (UHV), Roughing pump, High vacuum pump and Ultra high vacuum pump. After Roughing pump step, low vacuum state is caused. After High vacuum pump step, high vacuum state is caused. After Ultra high vacuum pump step, Ultra high vacuum state we want is caused. To make this process fast, using one High vacuum pump and one Ultra vacuum pump at the same time or using two of Ult
