    In 1970, Mitsubishi Heavy Industries, Ltd. (MHI) started to manufacture and market scales under a technical alliance with Inductosyn Corp., a scale manufacturer in the U.S. This alliance was formed for the establishment of position detection technology as the core of enhancing machine tool positioning accuracy. After the product name was changed to MP (Mitsubishi Precision) Scale in 1990, MHI continued with its original technology-incorporated and market needs-addressed product development. At present MP Scale is used in machine tools and presses not only in house, but also by our customers as a harsh environment-resistant, high-speed/high-accuracy scale. This paper introduces the Linear MP Scale, which detects the linear position, and its downsized and performance-improved controller (A/D converter) for the MP Scale, as well as the Rotary MP Scale with a built-in A/D converter for angle detection.
