Characteristics of each seal[5]
위의 표에서 보면, 가장 성능이 좋은 것은 종합적으로 봤을 때 Leaf seal임을 판단할 수 있다. 이러한 이유에서 우리 조에서는 이러한 Leaf Seal의 성능을 개선할 수 있는 방향을 모색해보고자 한다.

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
2. Marketing in Mobile Industry
In mobile product industry, Apple uses different strategy. Although Apple is maintaining the same brand and product image, and positioning itself in a similar manner, it is targeting on broader users. As a result, Apple possesses large market share in this sector. This sector consists of three products: an iPod, an MP3 player, iPhone, a smart phone, and an iPad, a
1. Introduction
1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
Crosstalk among neighboring interconnects
Capacitive crosstalk roughly proportional to kc=CIMD /CILD
⇒ Mainly fixed by the aspect ratio of lines and vias
⇒ Crosstalk level increases at each new generation
Induces delay uncertainty
A low-κ dielectric materials with a dielectric constant less than the dielectric constant of silicon dioxide, κ<4
First low-κ was applied at the
