In order to realize high machining and measuring accuracy of nano-meter order rationally, It is necessary and indispensable to investigate on various error factors on the whole machine system. In such a system, the most important factor determining the limit and boundary of machining and measuring accuracy is mechanical and thermal characteristics of many machine joints existing in a machine structure. Thus, it is necessary to develop the functional machine joint of new type having active functions in order to construct an ultra-precision machine tool or an ultra-precision measuring machine of the future.However, the machine joint having active and plural functions has not been investigated so far.Therefore, in this research, we developed two functional machine joints based on the new concept, i.e., the four-ball type and air-cushioned layer type. Furthermore, we ascertained the validity and effectiveness of those functional joints by incorporating them as the connecting mechanism between the table and its ball screw type driving system of a precision table. And it has been made clear that the proposed and developed machine joints have functions of controlled stiffness, damping and thermal characteristics.

为了合理地实现纳米级的高加工精度和测量精度，有必要对整个机床系统的各种误差因素进行研究。在这样的系统中，决定加工和测量精度的极限和边界的最重要因素是机器结构中存在的许多机器接头的机械和热特性。因此，为了构建未来的超精密机床或超精密测量机，有必要开发具有主动功能的新型功能机械关节。然而，迄今为止，还没有研究过具有主动功能和多功能的机械关节。因此，在本研究中，我们开发了两种基于新概念的功能机械关节，即，四球式和气封层式。此外，我们确定了这些功能关节的有效性和有效性，将它们作为工作台和其滚珠丝杠型驱动系统的精密工作台之间的连接机构。研究表明，所提出和研制的机械关节具有刚度、阻尼和热特性可控的功能。
