A self-contained heated wax treatment apparatus includes an outer shell and a rack disposed inside the outer shell. The rack includes a receptacle holder and at least one heater holder. At least a first receptacle is mounted to the receptacle holder of the rack. The first receptacle contains a heat activated substance. A heater is mounted to the heater holder of the rack in thermal conductive contact with the first receptacle. Activation of the heater causes heat to flow to the first receptacle and activate the heat activated substance inside the receptacle.

The disclosed heat-treatment furnace, used in a semiconductor-substrate heat-treatment step, is characterized by the provision of a cylindrical core, both ends of which have openings sized so as to allow insertion and removal of semiconductor substrates. This reduces standby time between batches during consecutive semiconductor heat treatment, thereby improving productivity. Furthermore, the use of a simple cylindrical shape for the structure of the core reduces the frequency at which gas-introduction pipe sections fail, thereby decreasing the running cost of the heat-treatment process.

A method for heat treatment of an electric power cable, the electric power cable including a polymer-based electrical insulation system with a polymer composition. The method steps include placing the electric power cable having the polymer-based electrical insulation system into a heating chamber and exposing the polymer-based electrical insulation system to a heat treatment procedure when the electric power cable is located in the heating chamber. The step of placing the electric power cable into the heating chamber includes winding the electric power cable about a substantially vertical center axis to form a substantially horizontal first layer of a plurality of substantially horizontal turns of the electric power cable, winding the electric power cable about the center axis to form a plurality of substantially horizontal second layers, each second layer being formed by a plurality of substantially horizontal turns of the electric power cable and stacking the plurality of horizontal second layers above the first layer. An apparatus is provided for performing the method.

A method for heat treating a metal tube or pipe is provided to perform heat treatment in such a manner that metal tubes or pipes (1) to be accommodated in a heat treatment furnace are laid down on a plurality of cross beams (22) arranged along a longitudinal direction of the metal tubes or pipes with the distance between adjacent cross beams being in a range of 200 to 2500 mm. This makes it possible to inhibit bending and scratches of the metal tubes or pipes without causing discoloration and deterioration of the manufacturing efficiency for the metal tubes or pipes. When the metal tubes or pipes (1) are laid down on the cross beams (22), spacers may be interposed between the metal tubes or pipes (1) and the cross beams (22) on which they are laid down.

An apparatus for treating a disc-shaped article comprises a spin chuck and at least three individually controllable infrared heating elements. The infrared heating elements are mounted in a stationary manner with respect to rotation of said spin chuck. The infrared heating elements are arranged in a nested configuration so as to define individually controllable inner, middle and outer heating zones adjacent a disc-shaped article when positioned on the spin chuck.
