摘要:
Under a magnetic field gradient, solid particles floating and/or sinking in a supporting liquid (most suitably a paramagnetic one) are levitated or anti-levitated at different locations depending on their densities and diamagnetic susceptibilities.

A mold product comprising liquid crystal composition for conducting heat. The liquid crystal composition contains liquid crystal polymer having an orientation degree α obtained by equation 1 below: Orientation degree α=(180−Δβ)/180 equation 1 In equation 1, Δβ is a half width in the intensity distribution obtained by fixing peak scattering angle in X-ray diffraction measurement and by varying the azimuth angle from 0 to 360 degrees, and orientation degree α is in a range between 0.5 and 1.0.

This invention relates to a method of producing polymer spherical bodies and is to produce a large size spherical body having no residual strain. This method comprises suspending a liquid monomer in a supporting liquid having a magnetic susceptibility χ2 larger than a magnetic susceptibility χ1 of any one of the monomer and the resulting polymer and not dissolving substantially the monomer, and applying a gradient magnetic field to the supporting liquid to float droplets of the monomer at a given position in the supporting liquid, and polymerizing and solidifying the droplets while maintaining a state that the droplet is substantially shaped into a sphere through surface tension. This method is made possible to produce polymer spherical bodies capable of using in optical application and the like.
摘要:
A thermally conductive formed article according to the present invention includes a matrix, and short carbon fibers which are present in the matrix. The short carbon fibers are oriented in a fixed direction in the matrix. A ratio I(002)/I(110) between an intensity I(110) of a diffraction peak ascribable to a (110) surface of carbon and an intensity I(002) of a diffraction peak ascribable to a (002) surface of carbon, occurring when X-rays are irradiated onto the thermally conductive formed article along the direction of orientation of the short carbon fibers, is 10 or less.
