Title: Radar signal processing device
Inventor: AKEI MASAHARU
IPC: G01S7/292
Filed: 1992-10-30
Abstract: PURPOSE:To realize easy tracking even in the case of the target with small reflected signal width by specifying an arbitrary pixel on the stored initial scan screen as the imaginary target, and obtaining the target probability from the target movement probability of each path and the non-noise movement probability of the pixel on the path. CONSTITUTION:A noise removing part 11 invalidates the information of the pixel amplitude below a reference amplitude on each scan screen. The information of the pixel amplitude which is valid in the removing part 11 is transmitted to an amplitude/ non-noise probability converting part 12. The converting part 12 refers to the amplitude/non-noise probability converting table 13, and converts the amplitude information of each pixel on the removing part 12 into the non-noise probability information. An imaginary target specifying part 15 reads the information on the initial scan screen from a pixel information storage part 14, and specifies the arbitrary perforated pixel as the imaginary target. A target movement probability computing part 17 refers to the target probability computing table 18 for the path where the imaginary movement path 16 is set, and the average target movement probability is obtained. The target probability computing part 19 obtains the true target probability from the target movement probability obtained by the computing part 17 and the non-noise probability.

Title: Washing machine
Inventor: NOMURA TOSHIHIRO
IPC: D06F17/10
Filed: 1988-11-18
Abstract: PURPOSE:To satisfactorily wash, to make the structure small in size, and to improve the convenience to use by equipping the machine with a magnet provided for either a rotating member or a stirring body, another magnet or a magnetic material, and a protruding piece part provided so that it can be lapped from the upper part of the peripheral part of the stirring body and rotatively driving the stirring body by a magnetic force. CONSTITUTION:When a motor 7 is driven, a rotating member 8 is rotated, magnets 9 are rotated, and a stirring body 13 is rotated according to the rotation of a magnet 16. The stirring body 13 is supported through a rib part 17 on the bottom part of a tank 10 under a point contact state. Since the stirring body 13 is rotated by the magnetic force, a stirring action and a scrubbing action soft for wash can be obtained. After washing completes, water in the tank 10 is drained by inclining the tank 10, and since a protruding piece part 19 is provided for the bottom part of the tank 10, the falling of the stirring body 13 can be obstructed. Since the machine has the structure in which the tank 10 is attachably and detachably provided for a driving part, when the water in the tank 10 is to be drained, the internal water can be drained in a draining place. Thus, provision of a draining means, is made unnecessary and the structure can be simplified.

Title: Method and apparatus for leading-in focus control state
Inventor: YAMADA SHINICHI
IPC: G11B7/085
Filed: 1989-11-10
Abstract: PURPOSE:To stabilize the leading-in of a focus by controlling a relative speed so as to be a prescribed value based on the output of a relative speed detecting means, thereby bringing the relative speed to the prescribed speed when a recording face and a focal position are coincident with each other. CONSTITUTION:A relative speed detecting means 21 detects the relative speed between a focal position and a recording face with a normalized focus error FE signal and gives an output to the terminal B of an arithmetic circuit 29 and a subtraction circuit 22. The circuit 22 subtracts the output of the circuit 21 from the output of an object speed setting circuit 30 and sends the result to a switch 23. The circuit 29 calculates the speed based on the just preceding relative speed inputted to a terminal A when the terminal B reaches a high level and gives the result to a switch 24. Then the switch 23 is opened and the switch 24 are closed to operate the focus control system, thereby applying the leading-in operation. Thus, the relative speed when a recording face and a focal position are coincident with each other is brought into the prescribed speed and the leading-in of focus is made stable.

Title: Heat pressure fixing device
Inventor: FUSE MASASHI
IPC: H05B6/10
Filed: 1985-12-25
Abstract: PURPOSE:To obtain good heat efficiency and to reduce power consumption by generating Joule's heat to a heat fixing roll made of a ferromagnetic body and heating a desired part concentrically. CONSTITUTION:An AC current is supplied to an exciting coil 6 to excite an exciting iron core 6, and then a closed magnetic path is constituted as shown by a dotted-line arrow to produce magnetic flux which penetrates a cylinder body 4 between the magnetic pole of the exciting iron core 5 and the magnetic pole of an auxiliary iron core 7. Thus, the magnetic flux which penetrates the rotating cylinder body 4 is produced to generate an eddy current at the magnetic flux penetration part of the cylinder part 4, so that the temperature of the cylinder body 4 rises owing to the Joule's heat. Namely, the cylinder body 4 is generated by the Joule's heat generated with the eddy current which flows through the cylinder body 4 itself. Consequently, the heat efficiency is good and the heating speed is increased.

IPC: G01N29/22
Filed: 1989-11-14
Abstract: PURPOSE:To obtain a peak level accurately by estimating the envelope of the waveform in full-wave rectification, computing the attenuation coefficient based on the peak value, and estimating the shape of the envelope accurately. CONSTITUTION:The absolute value of the reflected wave from a test piece T obtained with an ultrasonic wave probe with an absolute-value obtaining means 2. The output undergoes Fourier-series transformation in a Fourier-series transforming means 3. In a filtering operation means 4, the spectrum component higher than the natural vibration frequency of the probe is removed in order to remove the high frequency noise component based on overlapping minute defects and the like in a propagating path. The filtered output undergoes inverse Fourier transformation in an inverse Fourier transformation means 5. Thereafter, the output is multiplied by pi/2 in a pi/2 multiplying and converting means 6. When the first wave, the second wave and the like are processed in this way, an adequate envelope can be estimated. The peak values of the first wave, the second waves and the like are obtained in a peak-value operating means 7, and the operation is performed. Thus the ultrasonic wave attenuation rate can be evaluated highly accurately.
