    • A stand pipe is disposed so as to be fitted with the inner periphery surface of a piston rod with a hollow structure and a reservoir is incorporated into the inside of the stand pipe, whereby it becomes possible to reduce the size of an EHA device. Besides, since the reservoir is separated from both an annulus-side oil chamber and a bore-side oil chamber, a stable reservoir performance can be exhibited without being influenced by a fluid pressure resulting from an external force. Moreover, as a result of installation of the stand pipe, a difference between the amount of fluid required per unit stroke in the annulus-side oil chamber and that in the bore-side oil chamber becomes smaller, so that the required volume of the reservoir oil chamber can be reduced and it is possible to constitute an efficient EHA device with little difference between the energy consumption during compressing and that during extending. Consequently, it is possible to provide a reservoir built-in type actuator capable of exhibiting a stable performance without being influenced by an external force acting on the actuator and capable of attaining the reduction in size of the entire EHA device.
    • 立管设置成与具有中空结构的活塞杆的内周面配合,并且将储存器结合到立管的内部,从而可以减小EHA装置的尺寸。 此外,由于储存器与环空侧油室和孔侧油室分离,所以可以显示稳定的储存性能,而不受外力所致的流体压力的影响。 此外,由于安装立管,环形侧油室与孔侧油室的每单位行程所需的流体量之间的差异变小,所以容器的所需体积 可以减少油室,并且可以构成在压缩期间和延伸期间的能量消耗之间几乎没有差异的有效的EHA装置。 因此,可以提供能够显示稳定性能而不受作用在致动器上的外力的影响并且能够实现整个EHA装置的尺寸减小的储液器内置式致动器。

    • A plasma processing apparatus of the present invention can reduce a manufacturing cost of the apparatus and a footprint by decreasing a load applied to a device for varying a distance between electrodes in comparison with a conventional apparatus and, at the same time, easily meet a scaling up of a substrate to be processed. A lower electrode and an upper electrode are installed inside a vacuum chamber. Provided at a lower electrode supporting member are openings for operating the upper electrode by using a driving mechanism installed outside the vacuum chamber. An intermediate ring is installed at bellows for air-tightly sealing the openings. Further, the intermediate ring is connected to a connecting member connected to an upper electrode supporting member and the driving mechanism.
    • 本发明的等离子体处理装置与传统装置相比可以减小施加在用于改变电极之间的距离的装置上的负载,从而可以降低装置的制造成本和占地面积,并且同时容易地满足缩放 待处理的基底。 下电极和上电极安装在真空室内。 设置在下电极支撑构件处是通过使用安装在真空室外部的驱动机构来操作上电极的开口。 中间环安装在波纹管上,用于气密密封开口。 此外,中间环连接到连接到上电极支撑构件和驱动机构的连接构件。
