Patent number: 6468352Abstract: Particles are cooled at a particle introducing section by a cooling device. A vapor of modifying agent for modifying the particles is produced by heating the modifying agent in a vapor producing chamber by a heating device.

The modifying agent condenses on the surface of the particles by the production of the supersaturated vapor, and consequently, a film of the modifying agent is formed on the surface of the particles. A thick film of the modifying agent can be formed if this film forming step is carried out repetitively. Thus, modified particles having formed thereon a thick uniform film of the modifying agent can be produced by quite a simple manipulation in a very short time.Type: GrantFiled: November 20, 1998Date of Patent: October 22, 2002Assignee: Sharp Kabushiki KaishaInventors: Takahiro Horiuchi, Kiyofumi Morimoto
