The hardware and software of a microcomputer-aided system of X-ray scattering radiog-raphy has been described. The system uses finely collimated X-ray beam with a mechanical scanning of the specimen, and can give scattering radiographs in color after various image processings. The system capability has been demonstrated in observation of plastically defor-med metal plates and wooden materials. An advantage of a substraction image is also empha-sized for detecting a local structual modulation.
A compact automatic system for measuring many meteorological parameters was made to compare with results by a lasar radar. Using only one one-board microcomputer (Z-80), they were automatically and remotely measured at very short time intervals (4 seconds). And, by using a soft logic method and time allotment of very short intervals for the measurement of each parameter, improvements were made in compactness and wide application of the system. The measured parameters and their ranges of the system were as follows; wind speed (2.0_??_51.2m/s, resolution 0.2 m/s), wind direction (16 directions), air temperature (-16.0°C._??_35.2°C, 0.2°C) and relative humidity (30_??_90%, 0.5%). These values were chosen to cover the ones for the past several decades in Nagano City. The data obtained by this system clearly showed variations of atmospheric conditions. On these experimental results, the usefulness of the system is discussed.
