Title:
FALLOUT DECIDING DEVICE
Document Type and Number:
Japanese Patent JPS5548669
Kind Code:
A
Abstract:
PURPOSE: To realize a high-precision decision for the types of the sediments by providing such control means as to radiate the electric wave in parallel to the falling direction of the fallout.
CONSTITUTION: Based on the data detected by wind gauge 18, the falling direction of the fallout like the rain or snow. Then the remote control is given to turntable 20 via electric signal converter 19, and thus the transmission wave of fallout decision device 21 is set to always be parallel to the falling direction of the fallout. As a result, the effect of the wind can be eliminated by measuring the Doppler frequency, thus ensuring a high-precision decision for the fallout.
