A high-vacuum low-temperature atomic force microscope (AFM) for the direct observation of freeze-fracture samples has been developed. This AFM has a freeze-fracture mechanism inside the vacuum chamber. With this AFM it is possible to observe the fractured surface directly without both fabricating a replica and exposure to the ambient atmosphere. Both(More)
Multi-tasking machine tools have been increasing to shorten production time and improve productivity. It is indispensable for the operator of such machine tools to avoid collisions among the machine structures. In order to solve this problem, machine simulator is widely used before machining operations. In a commercial machine simulator, however, unexpected(More)
An autonomous machine tool has been developed to solve fundamental issues with the current command method using NC programs, and some key technologies for its realization have been devised. In the process planning system, various process plans are prepared, and the appropriate process plan can be selected to achieve flexible machining operations. Digital(More)
