Title: Radar echo video signal detection method and apparatus thereby
Inventor: JIYONII EI KOONETSUTO
IPC: G01S7/292
Filed: 1989-03-22
Abstract: PURPOSE: To track a target by averaging the magnitude of continuous radar echo signals for respective cells and generating a signal indicative of the average magnitude of respective cells. CONSTITUTION: Digitized video data corresponding to the position of respective cells are averaged over the number of continuous radar pulses in an azimuth sector. The number of pulses is a function of iteration rates. An averaging unit 30 sums up the magnitude of the signal for respective cells in a digital format and the accumulated value is divided by the number of trigger pulses in an azimuth angle sector of a line 24 to obtain an average video value for each cell. A first memory receives a data averaged for a distance starting set of one azimuth size and a second memory transfers a stored average data obtained for the azimuth size to a tracking unit 12 thus tracking a target.

Title: Flowing resistance controller for fluid by electric discharge
Inventor: ODA ATSUSHI
IPC: F15D1/12
Filed: 1995-02-20
Abstract: PURPOSE: To reduce the flowing resistance of fluid for an increase in flow velocity by generating electronic flow between an electrode oppositely-mounted onto an individual surface through a clearance, and an individual. CONSTITUTION: An electrode 6 is oppositely-mounted onto the top surface of the wing of an airplane, and a negative potential is given to the electrode 6 to generate electronic flow between the electrode 6 and the wing 1, by which the speed of air flow 2 over the top surface becomes high by destroying only the boundary layer of the top surface of the wing 1 to increase a difference between the air flow 2 over the top surface and the air flow 3 over a bottom surface, thus increasing lift. When an increase in a lift is required at the time of taking-off, landing or the like, the positive side of power supply is connected to the wing 1 by electric wiring from the power supply in an airframe to give negative potential to the electrode 6.  When the electronic flow is generated between the electrode 6 and the top surface 5 of the wing, the speed of the air flow over the boundary layer adhering to the top surface 6 of the wing 1 is high, and a difference in flow velocity between the air flow 2 of the wing top surface and the air flow 3 over the bottom surface increases, thus increasing the lift of the wing. Flowing resistance between fluid and an individual surface can be changed arbitrarily by electric operation, so it is possible to control flow velocity.
