Title: Radar device
Inventor: FUJISAKA TAKAHIKO
IPC: G01S7/28
Filed: 1982-03-18
Abstract: PURPOSE:To suppress the clutters of the backgrounds of not only a moving target, but  also a still transversal target, by using a transmitter with a frequency agility function,  serial-parallel converter, maximum likelihood estimation device, and averaging device for the clutter suppression. CONSTITUTION:The transmitter 3 transmits the (m)th pulse of frequency fm and a high  frequency received signal of the transmitted signal is detected by a receiver 4 and converted into a received signal Xm of intermediate frequency fo. This signal Xm is a  mixed signal of a target signal, clutter, receiver's noise, etc., and expressed by a time  series of Xm1-XmN at N sampling points. Then, this time series Xm is converted by  the serial-parallel converter 5 into a parallel signal, from which the amplitude Am and  phase phim of the target signal are estimated by the maximum likelihood estimation  device 6. Further, the transmission frequency is varied from f1-fm while m=1-M to  repeat the transmission M times and after M amplitude estimated values Am are obtained, the averaging device 7 is used to calculate the mean value of the values Am.  Thus, the serial-parallel converter converts the received signal Xm which is time-series  data into the parallel signal Xm, only the target signal is extracted by the maximum  likelikood estimation device 6, and the averaging operation with frequency agility is  employed to suppress an error in the estimation.

Filed: 1978-04-14
Abstract: PURPOSE: To provide a drum type washer for having a large washing capacity and a high economical efficiency, by locating at an inner circumference surface of a drum a lifter, which lifts up the washing, and washing boards which rubs the washing.  
     CONSTITUTION: At an inner circumference surface of a drum 7 are located a lifter 9 and washing boards 25, which are placed in positions which divide an inner circumference into equal portions centering around the lifter. The washing boards 25 has the height which does not allow the washing to be lifted up. Since the boards 25 do not lift up the washing, a relative speed is provided between the boards and the washing. Thus a projecting part 26 of the washing boards gives a rubbing action to the washing, and removes stains of the washing for cleaning. The filter 9 has such a washing function that lifts up and fall down the washing, and also agitates the washing so that a uniform rubbing action of the washing board can be performed.
