20120009344 | PROCESS AND APPARATUS FOR PRODUCING COMPOSITE MATERIAL - A process and an apparatus for producing a composite material utilize a rotatable hollow body that is inclined with an upstream side being higher than a downstream side. A reaction zone is defined within an elongated chamber in the hollow body. Protrusions inwardly extend from an inner peripheral wall of the hollow body adjacent to the reaction zone. Base material is input into the chamber via a base material introduction port and a carbon source vapor is input into the chamber via a carbon source supply port. A heater heats the reaction zone to a temperature at which carbon nanotubes form on the base material from the carbon source vapor. The protrusions catch base material disposed on the inner peripheral wall of the hollow body when the hollow body rotates and then drop the base material through the reaction zone so that the base material contacts the carbon source vapor. | 01-12-2012 |
20110065058 | ROTARY KILN AND PRODUCT - A rotary kiln includes: a cylindrical shell that includes a supply-side end portion and a discharge-side end portion at both ends in an axial direction of the shell, and a heat treatment chamber which is defined inside the shell and in which a heat treatment is performed on a process material; a supply-side holder that holds the supply-side end portion; a discharge-side holder that holds the discharge-side end portion; a supply-side rotary shaft that allows rotation of the supply-side holder; and a discharge-side rotary shaft that allows rotation of the discharge-side holder. The shell is rotated about its own axis by rotating at least one of the supply-side rotary shaft and the discharge-side rotary shaft. | 03-17-2011 |
20110065005 | ROTARY KILN AND BATTERY MATERIAL MANUFACTURED BY THE ROTARY KILN - A rotary kiln includes a cylindrical shell that rotates about its own axis and that has a heat treatment chamber provided radially inward of the shell. In the rotary kiln, a heat treatment is performed on a process material in the heat treatment chamber to manufacture a battery material. The shell is made of a carbon material. Since the shell is made of a carbon material, the rotary kiln can suppress contamination of metal scale, which adversely affects the battery material, into the battery material. | 03-17-2011 |
