Title: Wind disturbance prediction system
Inventor: INOKUCHI HAMAKI
IPC: G01S17/88
Filed: 2001-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a wind disturbance prediction system for measuring three- dimensional wind disturbance and verifying whether it is a reliable warning or not in advance. SOLUTION: A system is adopted, where a laser anemometer utilizing the doppler effect is mounted to an aircraft, scattered light from a wind disturbance region in front of a body that is flying is measured by performing conical scanning of laser beams for illumination to measure the speed of three-dimensional air flow at a remote site. The measured, three-dimensional airflow information is converted to only upper/lower wind for simply displaying two-dimensionally by considering the influence given to the body by upper and lower wind and front and rear wind, and decomposition is made to turbulence strength and average wind for wind turbulence for expression. Additionally, when the measured airflow information is to be transmitted to a steering person, the disturbance position is displayed with time until the disturbance is encountered as a reference instead of distance, thus partially cutting the cylindrical optical system in a wind measurement rider for improving mounting properties.

IPC: C11D17/00
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a soap which allows secure attachment of a soap piece, which has become thin, small and difficult to use, to a new soap so that the small soap piece can be exhausted as a part of the new soap. SOLUTION: An indentation having a depth of >=5 mm and an area of from 100 to 1,500 mm<2> is formed on a soap.
