摘要： A turbo-molecular pump of high safety and reliability was presented, so that if an abnormal condition should develop on the rotor side, it will not lead to any damage to the stationary portions such as the stator or pump casing to cause loss of vacuum in a vacuum processing system. The turbo-molecular pump includes a rotor; a stator assembly surrounding the rotor; and a casing portion surrounding the stator assembly, wherein at least a partial clearance is formed between the stator assembly and the casing portion, so that, when an abnormal torque is applied from the rotor to the stator assembly, direct impact transmission is prevented from the stator assembly to the casing portion.

摘要： An electron beam emitted from an electron gun (G) forms a reduced image on a sample (S) through a non-dispersion Wien-filter (5-1), an electromagnetic deflector (11-1), a beam separator (12-1), and a tablet lens (17-1) as an objective lens. The beam separator (12-1) is configured such that a distance by which a secondary electron beam passes through the beam separator is approximately three times longer than a distance by which a primary electron beam passes through the beam separator. Therefore, even if a magnetic field in the beam separator is set to deflect the primary electron beam by a small angle equal to or less than approximately 10 degrees, the secondary electron beam can be deflected by approximately 30 degrees, so that the primary and secondary electron beams are sufficiently separated. Also, since the primary electron beam is deflected by a small angle, less aberration occurs in the primary electron beam. Accordingly, since a light path length of a primary electro-optical system, it is possible to reduce the influence of space charge and the occurrence of deflection aberration.
摘要翻译：从电子枪（G）发射的电子束通过非分散维恩滤波器（5-1），电磁偏转器（11-1），光束分离器（12- 1）和作为物镜的平板电脑镜头（17-1）。束分离器（12-1）被构造成使得二次电子束通过分束器的距离比一次电子束通过分束器的距离大约三倍。因此，即使将分束器中的磁场设定为使一次电子束偏转等于或小于约10度的小角度，二次电子束可以偏转大约30度，使得初级和次级电子束充分分离。此外，由于一次电子束以小角度偏转，所以在一次电子束中产生较小的像差。因此，由于一次电光学系统的光路长度，可以减小空间电荷的影响和偏转像差的发生。
