Title: Heat exchanger
Inventor: MURATA SHIGETO
IPC: F28D7/16
Filed: 1986-12-15
Abstract: PURPOSE:To remove the deflection of a heating medium without increasing the fluidized resistance and to improve the heat exchange efficiency of a heat exchanger by installing one or more vanes inclined in a specific range with respect to the flow direction at a vessel inlet nozzle through which a primary heat medium flows. CONSTITUTION:One or more vanes are provided on the side of a plenum of a high-temperature side outlet nozzle by inclining the same in a range of 0-90 degrees with respect to the flowing direction of a heat medium. The heat medium flows into a shell 1 from the high-temperature side inlet nozzle 3 and reaches the plenum 7. At this time, since the heat medium forms a turning flow by the vane 8 fitted to the plenum side of the high-temperature side inlet nozzle, the flowing direction of the heat medium does not deflect only to the central part within the plenum but the flow rate of the heat medium becomes substantially uniform in the radial direction. Therefore, heat mediums which do not contribute to heat exchange are eliminated, and hence the heat exchange efficiency can be improved.

Title: Liquid-crystal-panel inspecting method
Inventor: KAWAGUCHI TAKAO
IPC: G01J1/42
Filed: 1990-11-01
Abstract: PURPOSE:To decrease the dispersion in judgments between inspecting workers and to make it possible to perform the highly accurate inspection of the quality of a panel by setting the luminance of the transmitted light through a liquid crystal panel at a certain value, and judging the quality of the liquid crystal panel. CONSTITUTION:This apparatus comprises a liquid crystal panel 11, a light emitting means 12 for displaying the liquid crystal panel 11, e.g. a light box, a luminance measuring means 13 for measuring the luminance of transmitted light l1 through the liquid crystal panel, e.g. a luminance meter, and a driving means 14 for the liquid crystal panel 11. The liquid crystal panel 11 on which light is emitted from the light emitting means 12 is driven with the driving means 14. The luminance of the transmitted light l1 through the liquid crystal panel 11 is detected with the luminance measuring means 13. The luminance of the transmitted light through the liquid crystal panel 11 is set at a specified value beforehand. Therefore, when a luminance signal s1 is fed back to the driving means 14, an inspection worker 15 can judge the presence or absence of the irregularities of the luminance under the specified luminance and can judge the quality of the liquid crystal panel. Thus, the dispersion in judgments between the inspection workers is decreased, and the highly accurate quality inspection of the panel can be performed.
