In shipbuilding, many sorts of measuring and datarecording tasks can be found in the production shops, and these tasks really occupy many man-hours, being compared with other works in production. Recently the remarkable development in the technology of electronics has made microprocessors and microcomputers available with very reasonable prices. The application of the these devices is expanding into various fields, taking advantages of the usefulness as a tool of automation and mechanization. Some examples of the application and development of microcomputers, as parts of machinery systems and devices in the following tasks in shipbulding, are reported in this paper. * measuring the thickness of coated paint. * measuring the dimensions of the container storage cells. * measuring the thickness of the chock-liners for main engine seats. * measuring the alignment of the center of the propeller shaft. * measurements in the test of the performance of the generators. These five microcomputer-applied devices have accomplished designed performance successfully, resulting in the remarkable reduction in man-hours of operation.
