  • Patent number: 11959872
    Abstract: The present invention provides a method for accurately measuring a blood component despite uneven distribution of blood introduced into a capillary. The measurement method according to the present invention is characterized in that a plurality of electrode systems for measuring the hematocrit are provided in a capillary of a biosensor to measure the hematocrit at different positions in the capillary. By measuring the hematocrit at the plurality of positions in the capillary as described above, the hematocrit can be measured mom accurately despite uneven distribution of blood introduced into the capillary.

  • Publication number: 20140086927
    Abstract: Antibodies (Abs) play roles in protection against influenza. Neutralizing Abs either inhibit the binding of hemagglutinin (HA) to cellular receptors or prevent the conformational change of HA induced by low pH. The former Ab binds to the regions near the sialic acid-binding pocket on the globular head formed by HA1 and generally shows narrow strain specificity. The latter Ab binds to the stem region formed mainly by HA2 and shows broad strain specificity. We isolated a broadly neutralizing Ab against H3N2 viruses. X-ray analysis of the HA/Ab complex indicated that the Ab binds to the valley formed by two neighboring HA monomers at the side of the globular head. The Ab shows neutralizing activity by preventing the conformational change of HA induced at low pH.

  • Patent number: 7160049
    Abstract: An electromagnetic absorber formed of conductive fiber or the like, such as carbon fiber having an overall length corresponding to the wavelength of electromagnetic waves to be absorbed, is mixed into a base material to form an electromagnetic wave-absorbing pavement material. The electromagnetic wave-absorbing pavement material is used to form a pavement having an electromagnetic wave absorbing course. Further, an electromagnetic wave reflecting course is disposed under the electromagnetic wave absorbing course, and the electric length of the electromagnetic wave reflecting course is set to a predetermined value in relation to the dielectric constant so that electromagnetic waves reflecting off the surface of the electromagnetic wave absorbing course and electromagnetic waves reflecting off the electromagnetic wave reflecting course have opposite phases and thereby cancel each other out, whereby the electromagnetic waves are absorbed well.

  • Patent number: 5727327
    Abstract: A centering apparatus and method is provided which automatically measuring the radius or radius deviation of a large cylindrical bore, and shorten the time required for centering. The inspection apparatus is supported on a rise and fall base which is horizontally supported on a top portion of the large cylindrical bore in such a manner that it is allowed to vertically move in parallel with a fine wire which is hung perpendicularly from the center of the top portion. The inspection apparatus having a non-contact type two-dimensional position sensor for detecting the relative position of the fine wire to the cent-er of the inspection apparatus. The inspection apparatus is positioned at an arbitrary height.
