A correction data creating method is provided. In the method, a source voltage is sequentially selected among a plurality of source voltages determined in advance and the selected source voltage is supplied to a heater for heating a substrate support. At the source voltage supplied to the heater, a power supplied to the heater is adjusted such that a resistance of the heater becomes a resistance value corresponding to a predetermined first temperature based on temperature conversion data indicating a relationship between the resistance of the heater and a temperature of the heater. A temperature of the substrate support is measured at a position where the heater is disposed as a second temperature. A correction value corresponding to the difference between the predetermined first temperature and the second temperature is calculated, and correction data indicating a corresponding relationship between each of the source voltages and the correction value is created.

A heat treatment facility performing a heat treatment on a workpiece, the heat treatment facility includes: a treatment container in which the workpiece is housed; a heater which is provided in the treatment container and heats the workpiece by radiation heat at least from below the workpiece; and a plurality of support posts which are provided in the treatment container and support the workpiece.

An atomization unit has a tube-shaped furnace, and heats and atomizes a sample injected into the furnace. A light source unit emits light having a wavelength to be measured toward the atomization unit such that light passes through the furnace. An optical system transmits the light having the wavelength to be measured, of light passing through the furnace. A detection unit detects the light transmitted by the optical system. A light transmission plate is provided at a position in an optical path of the light passing through the furnace toward the detection unit, to obliquely cross an optical axis of the light. An image capturing unit is arranged outside the optical path, and captures an image inside the furnace by receiving light reflected by the light transmission plate, of the light passing through the furnace.

In various embodiments, apparatuses for receiving and supporting one or more components during processing thereof at process temperatures greater than approximately 1000 C. feature refractory metal shelves separated by refractory metal support posts.

A method and plant for the thermal treatment of friction elements including a convective heating step which is performed within a convective tunnel oven. The friction elements are arranged laid, in an orderly manner, upon a plurality of trays each tray having a perforated resting plate upon which the friction elements are laid in a position next to one another only, but not overlapped. The trays are piled on top of each other whilst being kept distanced from one another in a stacking direction by an amount that is greater than the thickness of the friction elements. Groups of piled up trays containing the friction elements are arranged side by side on belt conveyor means that pass through the tunnel oven in order to transport the friction elements therethrough.

The present invention relates to devices used during the thermomechanical treatment of workpieces. During thermochemical treatment, metallic workpieces are mounted on and/or shielded by a high-temperature-resistant device configured specifically for this purpose in order to reduce dimensional and shape changes or warping. The inventive devices provide support and flow guiding for metallic workpieces during thermochemical treatment, and include a plate or a ring having a first and a second face, in which the second face is equipped with three or more support elements and the support elements are bound to a support plane.

A multi-window platen oven for simultaneously heating a plurality of blanks, for example aluminum blanks, before forming the heated blanks in a production line is provided. The oven includes a plurality of vertically aligned shelves disposed in an existing press assembly so that no additional floor space is required. The shelves are attachable to an upper press bed and one another. The upper press bed lifts the attached shelves to present an open window for receiving an unheated blank and/or removing a heated blank from the oven. The remaining windows remain closed and continue heating while the blanks are transferred to and from the oven. After closing the one open window, another window opens to receive another unheated blank and/or remove another heated blank. Thus, the multi-window platen oven continuously provides blanks which are ready for warm or hot forming.
