  • Publication number: 20240116840
    Abstract: An object is to provide a compound that can be a novel curing agent. The compound suppresses volatilization of the curing agent that can lead to a decrease in function of a prepreg, contamination of equipment for producing the prepreg, and in addition a decrease in production yield of the prepreg, and further contributes to improving dielectric properties. As a solution, a tris(allyl ether) compound represented by general formula (1) below is provided.

  • Patent number: 9183966
    Abstract: A composite resin material particle is produced by a method including the steps of: forming a mixed slurry containing a resin material particle and carbon nanotubes; supplying the mixed slurry to a pressure vessel, followed by supplying carbon dioxide with stirring an inside of the pressure vessel; holding the inside of the pressure vessel at a temperature and at a pressure which allow the carbon dioxide to be maintained in a subcritical or supercritical state; and transferring the carbon dioxide to the outside of the pressure vessel.

  • Publication number: 20110318256
    Abstract: A method and apparatus for continuously synthesizing oriented carbon nanotubes, with which oriented carbon nanotubes can be stably synthesized in large quantities, is presented. The method and apparatus for continuously synthesizing oriented carbon nanotubes comprise: a coating and drying step in which a catalyst liquid is applied and dried to form a catalyst layer on a substrate surface; a catalyst substrate formation step in which the catalyst layer is heated to form a catalyst substrate having a catalyst particle layer on the substrate surface; a synthesis step in which a raw material gas heated to a temperature equal to or higher than a synthesis temperature for the oriented carbon nanotubes is brought into contact with the surface of the catalyst substrate to synthesize oriented carbon nanotubes; and a collection step in which the oriented carbon nanotubes are collected.

  • Patent number: 5743930
    Abstract: The apparatus for manufacturing inorganic spherical particles according to the present invention consists of a vertical sphering furnace, a sphering burner disposed at the top of the furnace, a particle outflow pipe through which spherical particles formed in the furnace are drawn out therefrom and an air inflow pipe for introducing air for carrying the spherical particles toward the opening of the particle outflow pipe; wherein the particle outflow pipe and the air inflow pipe are arranged to oppose each other horizontally at a lower position of the furnace. The opening diameter of the particle outflow pipe is designed to be larger than that of the air inflow pipe.
