Naturally all instruments used in industrial fields are artifacts designed by engineers then their behavior are derived from their design information. In addition to the fact, the method for disassembling/assembling them can be obtained through analysis of the information and it leads to an automatic generation of interface which gives us a plain explanation. The research aims to develop such an intelligent fault diagnostic system. For the purpose the following three works have been studied.(1)Development of consulting system: From the description of the instrument to be examined, possible ways to disassemble it are derived and the most efficient one is selected to reach the component suspected by the diagnostic system. In this case, graceful graphic explanation is generated for the user not to misunderstand the object to be disassembled.(2)Derivation of disassembling method and behavior of an instrument: More efficient disassembling way than that obtained in (1) are obtained using a standard assembling sequence which is given in a manual. Naturally objects are divided into several modules, and the whole object will be completed after each module have been achieved. By analyzing texts and estimating what kind of joint relations are made among mechanical parts, the behavior of the assembly and efficient disassembling way can be found.(3)Understanding of illustration in manual: Verbal explanation is not always adequate as a method to give instruction, especially to tell how to disassemble/assemble an object. To understand texts in a manual needs to recognize the meaning of an illustration attached to them. Auxiliary lines are the key to determine an orientation of a parts and the result constraints the orientation of the parts to be mated with the one.

当然，工业领域中使用的所有仪器都是由工程师设计的工件，然后它们的行为来自它们的设计信息。除此之外，通过对这些信息的分析，还可以得到拆卸/组装它们的方法，并自动生成界面，这给了我们一个简单的解释。本研究旨在开发一个智能故障诊断系统。为此，研究了以下三项工作。（1）咨询系统的开发：从被检仪器的描述中，推导出可能的拆卸方法，并选择最有效的方法到达被诊断系统怀疑的部件。在这种情况下，为用户生成优美的图形解释，以避免误解要拆卸的对象。（2）拆卸方法的推导和仪器的性能：使用手册中给出的标准组装顺序获得比（1）中获得的更有效的拆卸方法。自然地，对象被划分为若干模块，并且在实现每个模块之后，整个对象将被完成。通过对文本的分析，判断机械零件之间的连接关系，可以发现装配行为和有效的拆卸方式。（3）对说明书中插图的理解：口头解释并不总是足以作为一种给予指导的方法，特别是告诉如何拆卸/组装一个物体。为了理解手册中的文本，需要认识到附在它们上面的插图的含义。辅助线是确定零件定位的关键，其定位结果约束着待配零件的定位。
