20140044148 | DEVICE AND METHOD FOR MEASURING TEMPERATURE OF HEAT-TREATED WORKPIECE - A device is provided with a measurement window, which is provided in a heat treat furnace and which permits direct visual observation of a surface to be measured of a heat-treated workpiece, and a temperature sensor, which is provided outside the measurement window and which is capable of carrying out noncontact measurement of the surface temperature of the surface to be measured through the measurement window. The temperature sensor has a measurement wavelength range in which the absorptivity by water is low (e.g., 1.95 μm to 2.5 μm). Further, the measurement window is composed of a window material having a high transmittance in the measurement wavelength range (e.g., germanium). | 02-13-2014 |
20130142212 | GRAPHITIZATION FURNACE AND METHOD FOR PRODUCING GRAPHITE - Graphite is produced from powder as a carbon source by means of a graphitization furnace. The graphitization furnace is comprised of: an electrically conductive crucible including a hollow configured to house the powder; an electrode including a columnar shaft and a head provided at an end of the shaft, the head having a shape selected from the group consisting of a sphere, a hemisphere, a column with a rounded edge, a cone, and a cone with a rounded tip; and a power source configured to apply electric current to the powder through the crucible and the electrode. | 06-06-2013 |
