An embodiment of the present disclosure relates to a heating device comprising a carbon nanotube, which comprises a carbon nanotube layer containing aligned carbon nanotube carpet, a first electrode and a second electrode having a predetermined distance between each other and electrically connected to the carbon nanotube layer respectively, wherein a current produced by applying a voltage to the first electrode passes laterally via the diameter direction of the aligned carbon nanotubes from the first electrode to the second electrode. The present disclosure also includes methods for manufacturing the aligned carbon nanotube carpet.

Nanotube heating device comprising carbon nanotube and manufacturing method thereof

The present invention discloses a method for producing carbon nanocoils, which comprises: providing a metal substrate; depositing a tin precursor on the substrate; heating the substrate with the precursor to a predetermined temperature to form a catalyst on the substrate; placing the substrate in a quartz tube furnace; and introducing carbon source gas and protective gas into the quartz tube furnace to allow carbon nanocoils to grow on the surface of the catalyst. Another method for producing carbon nanocoils is also disclosed, which includes: depositing a mixed solution of iron acetate and tin acetate on a substrate; heating the substrate with the mixing solution to a predetermined temperature to form a catalyst on the substrate; placing the substrate in a quartz tube furnace; and introducing carbon source gas and protective gas into the quartz tube furnace to allow carbon nanocoils to grow on the surface of the catalyst.

Method for producing carbon nanocoils

A power-saving switch control mechanism for hand-held electric appliance comprises a sensor to detect the approaching hand of user and then continuously transmit signals to activate a switch into a close-circuit status in order for a cell to supply power to a control circuit of the electric appliance. When the sensor fails to detect the hand on the electric appliance, the switch returns to an open-circuit status to stop the cell from supplying power to the control circuit and stop the operation of the electric appliance accordingly.
