  • Publication number: 20220243072
    Abstract: A corrosion-resistant member including: a metal base material (10); and a corrosion-resistant coating (30) formed on the surface of the base material (10). The corrosion-resistant coating (30) is a stack of a magnesium fluoride layer (31) and an aluminum fluoride layer (32) in order from the base material (10) side. The aluminum fluoride layer (32) has a first crystalline region (32A) and a second crystalline region (32B) containing crystalline aluminum fluoride. The first crystalline region (32A) is a region in which diffraction spot arrays having regularity are observed in an electron beam diffraction image obtained by irradiation with electron beams having a beam diameter of 10 nm to 20 nm. The second crystalline region (32B) is a region in which a plurality of diffraction spots is observed but diffraction spot arrays having regularity are not observed in an electron beam diffraction image obtained by irradiation with the above-described electron beams.

  • Publication number: 20220242377
    Abstract: The vehicle control system includes a braking force generating device (6, 22) configured to generate a braking force to shift a load of a vehicle to a side of front wheels thereof at an initial stage of a cornering, and a control device (31) configured to control the braking force generated by the braking force generating device. The control device calculates an additional deceleration (Gxadd) according to vehicle state information, calculates a requested fore and aft acceleration (Gxr) according to a requested fore and aft force (Fxr) for the vehicle, calculates a correction coefficient (K) for weakening the additional deceleration according to the requested fore and aft acceleration, corrects the additional deceleration by the correction coefficient, and calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the corrected additional deceleration.

  • 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: 5924534
    Abstract: The invention provides a continuously variable transmission which is compact and high in operation efficiency, and allows smooth starting and smooth change-over between forward running and backward running. The continuously variable transmission includes a torque converter which in turn includes at least three runners of an impeller, a first turbine and a second turbine. The continuously variable transmission further includes a lock-up clutch operable to couple the impeller and the first turbine to each other, and a hydraulic brake disposed on a first turbine shaft connected to the first turbine and capable of being fixed to a housing. The second turbine is connected to a second turbine shaft connected to a pulley of a transmission via a one-way clutch which transmits a force only when the second turbine rotates in a direction reversed to the direction of rotation of the impeller.
