Title: Pulser built-in type seal
Inventor: TAKAOKA SHUJI
IPC: F16J15/326
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To detect accurate number of revolution by alternately arranging N poles and S poles in the circumferential direction of the core metal of a hermetic seal. SOLUTION: An inner ring 1 and an outer ring 2 are so fixed that mutual rotation is possible via a ball 3 as a rolling element. A wheel and a brake pad are fixed to the outer ring 2. A hermetic seal 8 is fitted to the outer ring 2 inner periphery which rotates, and has an annular core metal 9 for stiffening which is composed of magnetic substance. N poles and S poles are alternately arranged in the circumferential direction of the core metal 9. A lip part 10 composed of elastic material is fixed to the core metal 9. On the facing surface of the hermetic seal 8, a proximity coil is fixed to a car body which does not rotate. Only by installing the hermetic seal 8, the effect that a pulse generation functional body is installed can be obtained.  Since the hermetic seal 8 is installed between the outer ring 1 and the inner ring 2, the possibility that small stones enter and cause damage does not exist, and accutate number of revolution can be detected.

The light transmitted through the sensor head 2 is output through an outgoing fiber collimator 10 and received through an optical fiber 22 to be converted into an electrical signal corresponding to the outgoing light (light signal). Then, the electrical signal from a light receiving element 24 is introduced separately to an equiangle frequency component detector 26 and a double angle frequency component detector 28, and a desired angle frequency component is extracted from an input electrical signal. Then, the results are outputted via a dividing circuit 30.

IPC: H04N1/409
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce noise from a binary gradation image consisting of black pixels and white pixels. SOLUTION: A converter 31 converts a '1' level (white pixel) and a '0' level (black pixel) in binary gradation image data stored in a 1st memory 21 into a '255' value and a '0' value respectively and the converted values are stored in a 2nd memory 23 in the noise reduction device. Then a calculation means of a filter section 24 sequentially scans pixels in the binary gradation image data stored in the 2nd memory 223, calculates a total sum of the pixel values in an area consisting of pluralities of pixels around a target pixel and stores the result to a 3rd memory 25. Then a pixel replacement means consisting of a setting value area 34 storing a prescribed reference value and a discrimination means 33 compares the total sum stored in the 3rd memory 25 with the reference value.  In the case that the total sum is higher than the reference value, either of the binary values (in this case, the value '1') is set again to the target pixel and in the case that the total sum is smaller than the reference value, the other binary value (in this case, the value '0') is set again to the target pixel.
