Title: Magnetic flaw detection for pipe inside face
Inventor: KAMIMURA SHIGENORI
IPC: G01N27/84
Filed: 1981-06-06
Abstract: PURPOSE:To detect accurately defects in the axial direction of a wide-range part of a steel pipe having a proper magnetic field, by arranging a rectangular electromagnet in the steel pipe eccentrically toward one side. CONSTITUTION:An electromagnet 6 is arranged in a steel pipe 1 so that a magnetic pole 6a is parallel with the axial direction of the steel pipe 1 and the electromagnet 6 is deflected to one side from a center axis 11 not to be brought into contact with the inside face of the steel pipe 1. By this arrangement, the inside of the steel pipe 1 is divided to a narrow arc part in one side of the electromagnet 6, namely, a narrow-range part A and a wide arc part in the other side, namely, a wide-range part B. When an AC current is supplied to a coil 7 of the electromagnet 6 to make the narrow-range part A saturated magnetically by a magnetic flux 12 and a proper magnetic field is given to the wide- range part B by a magnetic flux 13, the magnetic powder pattern of a defective part 5 is formed accurately because the fluorescent magnetic powder scattered from a nozzle 10 is scattered in the proper magnetic field.

Title: Oil-water separating film and its production
Inventor: KONDOU YOSHIKAZU
IPC: B01D69/14
Filed: 1982-05-22
Abstract: PURPOSE:To form a porous film suited for separating oil and water selectively from a liquid mixture of oil and water by filming a hydrophobic polymer and a hydrophilic polymer so as to have the specific phase sepn. structure. CONSTITUTION:A hydrophobic polymer A such as fluorinated vinyl polymer, polyolefins, synthetic rubber or the like and a hydrophilic polymer B such as celluloses, PVA deriv., PVC deriv. or the like are mixed at a specific ratio and a film wherein one of the polymers is dispersed in a granular state is formed. The film is stretched at least uniaxially to form holes between the separated two phases of the polymer A and the polymer B. The film wherein the polymer B is dispersed in a granular state in the polymer A is used to separate water selectively from a mixture of oil and water and the film wherein the polymer A is dispersed in the polymer B is used to separate oils selectively. The film has the surface less vulnerable to contamination by oil and water and has a small decrease in the rate of treatment.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce the degree of narrowing dynamic range within the absolute minimum in order to cut off spike noises by obtaining the difference between a gradation maximum index and a gradation minimum index and using it for a range index. SOLUTION: A fixed length compression section encodes data in 128 bits, according to a prescribed compression system into 48-bit data consisting of an 8-bit range index LD denoting a density range in a block, of an 8-bit density index LA expressing a block density, and of a quantized pixel value in total in 32 bits, comprising each 2-bit obtained on the basis of the range index LD and the density index LA. This fixed length compression section obtains the gradation maximum index Qmax and the gradation minimum index Qmin. Thus, this image processor is reduced in the number of comparison processings and simplified in circuit configuration. Furthermore, the image processor obtains the mean value index LA and the gradation width index LD, on the basis of the gradation maximum index Qmax and the gradation minimum index Qmin.  Thus, the dynamic range is prevented from being narrowed unnecessarily.

Abstract: PROBLEM TO BE SOLVED: To ensure a reflection part without caring of a protruded object such as a reinforcing member, a fluorescent lamp holder and a mounting bolt, by illuminating the front surface of an external signboard with direct light from a light source and also reflected light by a foldable reflection film arranged behind the light source. SOLUTION: The display parts 1A for lines of an external signboard 1 and others such as a display part for character and figure are illuminated by both light beams of direct light from a fluorescent lamp 12 incorporated in the external signboard 1 and also reflected light from a reflection film 70 arranged along from the fluorescent lamp 12 to a plastic frame 51. In this case, when the central part of the fluorescent lamp holder supporting the fluorescent lamp 12 is cut off, the whole rear part of the fluorescent lamp 12 easily reflects the light.  Consequently, an observer seeing the external signboard 1 sees both light beams of direct and reflected light from the fluorescent lamp 12 as the light beam transmitted through the transmitting part 1A2 of the display part 1A of the line of the external signboard 1 and as the light beam illuminating the surrounding of a display part 1A3, etc.

Title: Oil leakage sensor
Inventor: KATO MASAO
IPC: G01V9/00
Filed: 1987-04-08
Abstract: PURPOSE:To rapidly and surely detect an oil leakage even in a slight amount by fitting a rubber accommodating vessel of an inverted truncated cone shape and swelling rubber pieces, coupled with a lever action to obtain a large quantity of motion even by a slight volumetric expansion change. CONSTITUTION:When an oil leakage occurs in a pipeline of a petroleum machinery product or connecting parts thereof, oil drips and splashes on rubber pieces 1 from the upper part of a spiral disk 3 via punch holes 4, and the rubber pieces 1 begin to cause volumetric expansion. The movements of rubber pieces 1 restricted by a tapered rubber accommodating vessel 2 are all directed to slipping out toward an upper opening and pushing the spiral disk 3 upward. Although the outer peripheral part of the spiral disk 3 is fixed, since a spiral hole is formed, the spiral disk 3 expands upward in a spring form, and a central protrusion pushes up a first lever 7. Its movement is slightly expanded and pushes up a second lever 8. The second lever 8 further enlarges its action to push up a contact plate 10 and opens a contact part 14 to emit signals for stopping the operation of an electronic control part and warn of the oil leakage.

Abstract: PROBLEM TO BE SOLVED: To enable to simply and easily remove soil or old wax on sporting goods, by attaching a wiping mat on a can main body of a cleaner to remove soil or old wax. SOLUTION: On the surface of a can main body 1, a wiping mat 2 constituted of paper in a laminated form is attached. The wiping mat 2 is structured to have an adhesive face on one side and a face with a releasing function, such as a synthetic resin sheet, on the other side only in the periphery part so as to use the paper peeling in a layer on use so that it is disposed when it became old. Since the wiping mat 2 does not cover whole the periphery of the can main body 1, desired design, notice, trade mark, etc., can be shown as it is on uncovered parts of the main body 1. The number of wiping mat layers to be provided is properly decided considering the volume of the cleaner can or soil on sporting goods.

Filed: 1981-06-10
Abstract: PURPOSE:To improve the characteristc of a coded color signal and to reproduce a high-quality color picture, by extracting a coded signal through a low pass digital filter. CONSTITUTION:The three primary color picture signals R, G and B given through a color camera 1 are fed to a matrix circuit 2 and converted into a luminance signal Y and two color difference signals R-Y and B-Y. These signals are applied to the low pass analog filters 3-5 respectively to be almost eliminated for the undesired high band component and then applied to the A/D converters 6-8 to be coded. These coded signals are converted into a coded luminance signal and two coded color difference signals resectively. These coded color picture component signals are applied to the low pass digital filters 9-11 to be limited to each prescribed signal band and then fed to a sampling circuit 12. Thus the first sample values are thinned properly with each prescribed sampling cycle. After this, the signals are supplied to a video switch 13 and transmitted to a transmission system within a station, etc. for example.
