  • Patent number: 10603869
    Abstract: A laminated structure has a first layer formed from a fiber reinforced plastic, a second layer formed from a fiber reinforced plastic and arranged opposed to the first layer, a first core layer formed from a first resin foam and arranged between the first layer and the second layer, and a second core layer formed from a second resin foam and arranged between the first core later and the second layer. The first resin foam has a higher flame resistance than the second resin foam. A laminated structure having flame resistance and high strength enough to endure a bird strike or the like at the same time can be manufactured at relatively low manufacturing cost.

  • Publication number: 20180372698
    Abstract: A liquid chromatography device includes a column that separates components in a specimen sample, an eluent supply mechanism that alternately supplies two or more types of eluent to the column, and a detection apparatus into which the eluents are introduced after having passed through the column. The detection apparatus detects a specified component of the sample contained in the eluents. The detection apparatus includes a flow cell, a light source, a light-receiving unit, and a scattering plate. The flow cell includes a flow channel through which the eluents flow. The light source is provided outside of the flow cell and irradiates light onto the eluents flowing through the flow channel. The light-receiving unit is provided outside of the flow cell and receives light that has passed through the flow cell. The scattering plate is provided between the light source and the light-receiving unit along a direction of travel of light from the light source.
