  • Publication number: 20060224080
    Abstract: In a body fat measuring apparatus, a constant electric-current is flowed between hand electric-current electrodes and leg electric-current electrodes. From two detected voltages generated between an annular-shaped voltage electrode placed on an abdominal portion and two voltage electrodes placed at the both sides of a lumbar portion, two abdominal impedances are determined. Two electric-current electrodes and two voltage electrodes are placed such that they are spaced apart by a small interval from one another at an umbilicus portion. A constant electric current is flowed between the two electric-current electrodes and the impedance in the vicinity of the subcutaneous of the abdominal portion is determined from the detected voltage generated between the two voltage electrodes. From the two abdominal impedances, the impedance in the vicinity of the subcutaneous of the abdominal portion, and the input physique information, a viscera impedance is calculated.

  • Patent number: 6918808
    Abstract: A discharge lamp arc tube in which a pair of electrode assemblies each having an electrode rod, a sheet of molybdenum foil and a lead wire integrally series-connected to one another have respective molybdenum foil containing regions pinch-sealed with glass, and electrodes are disposed opposite to each other in a closed glass bulb containing a light emitting substance or the like enclosed therein. The surface of the sheet of molybdenum foil sealed at each of the pinch seal portions has a micro-asperity surface roughened by an etching treatment including oxidation and reduction, so that silica glass is closely packed in the micro-asperity of the surface of the sheet of molybdenum foil. As a result, the adhesion (mechanical bonding strength) in the interface between silica glass and molybdenum foil is improved so that foil rising is suppressed and, accordingly, the lifetime of the arc tube is extended.

  • Patent number: 6555836
    Abstract: A method of inspecting bumps provided on a surface of an object to be inspected includes the steps of: (a) irradiating a first irradiation beam on said object in an oblique direction and (b) imaging a first reflected beam from said object so as to obtain a first reflection image including a first reflection region and a height data of said bump corresponding to said first regular reflection region produced by a part of the first reflected beam reflected near an apex of the bump. The method further includes the steps of (c) shifting a position of said first regular reflection region in said first reflection image in accordance with a value derived from said height data and said predetermined angle, (d) extracting said first regular reflection region within a predetermined region from said first reflection image after said step c), and (e) detecting a height of said bump based on said height data corresponding to the extracted first regular reflection region.

  • Patent number: 6104493
    Abstract: The bump height is measure din a sample area on a wafer, the bump height distribution on the wafer is estimated on the bases of the measured value, the portion where the estimated height distribution is out of a predetermined range is determined as an inspection area, and the bump height is measured in the inspection area, and a chip area having a bump height out of a predetermined range is judged to be defective. Data of the inspection areas and inspection results are accumulated, and the inspection density is renewed on the basis of the accumulated data. In another method, the inspection area is divided into rectangular blocks so that each block has a width of approximately equal to a light beam scanning length and a distance between any adjacent bumps in the feeding direction is less than a predetermined value, feeding path being perpendicular to the scanning direction.

  • Patent number: 5999266
    Abstract: The present invention is a method for inspecting height, scanning the surface of a subject item having zones of different reflectance with incident light of a prescribed intensity, causing the reflected light from the surface to be imaged with means for detecting light spot positions, and detecting the height of said surface from the light spot position which was imaged, said method comprising: a step of scanning, in a second zone with low reflectance surrounding a first zone with high reflectance with a first intensity of incident light, which is low to the degree that said means for detecting light spot positions is not saturated even with said high reflectance; and a step of scanning, if it is detected that the quantity of light of the imaged light of said reflected light exceeds a prescribed threshold value, with an appropriate second intensity of incident light found from said intensity of incident light and said detected quantity of light at the time of the preceding scan.
