A method of manufacturing an electrode for a battery and a system for drying an electrode are disclosed and the system is used to manufacture an electrode. The system for drying an electrode includes a coil disposed along a movement route for an electrode. The electrode includes a base layer made of metal and an electrode active material applied onto the base layer. An electric current may be applied to the coil.

A heat treatment apparatus includes a furnace body and a cooling device. The furnace body has therein a processing space where a workpiece is heat-treated. The cooling device cools the processing space within the furnace body. The furnace body is provided with a first opening and a second opening. The cooling device includes an inner pipe, an outer pipe, a refrigerant supply unit, and an air supply unit. The inner pipe is provided outside the furnace body. The inner pipe couples the first opening and the second opening. The outer pipe encloses at least a portion of a periphery of the inner pipe. The refrigerant supply unit supplies a refrigerant between the inner pipe and the outer pipe. The air supply unit sends air through the inner pipe from the first opening toward the second opening.

A cylinder for drying a fibrous web has a cylinder shell, wherein an electric heating device for heating the cylinder is arranged inside the cylinder. The electric heating device is arranged on the inside of the cylinder shell, forming a conductive thermal connection, wherein the electric heating device comprises at least one electric heating element with carbon nanotubes. This provides a cylinder with a heating device with improved efficiency.

A heating apparatus, an image forming apparatus, and a liquid discharge apparatus. The heating apparatus includes a heating roller having a heat source inside, an end holder in which a portion of the heat source is disposed, the end holder holding an axial end of the heating roller rotatably, and an air supply device configured to supply air into the end holder in a direction intersecting with an axial direction of the heating roller. The heating apparatus includes a heating roller having a heat source inside, and an end holder in which a portion of the heat source is disposed, the end holder rotatably holding an axial end of the heating roller. In the heating apparatus, the end holder has an air inlet opening through which air is supplied into the end holder and an air outlet opening through which air is ejected outside from inside the end holder.
