Abstract: Disclosed is an ion gage using a carbon nano-tube, more specifically a pressure sensor using a field emission of the carbon nano-tube. An array of carbon nano-tubes is formed on a metallic layer. A first grid is disposed on the array of the carbon nano-tubes. A second grid is disposed on the first grid in such a manner as to be spaced apart by a certain desired distance from the first grid. A collector is disposed on the second grid in such a manner as to be spaced apart by a certain desired distance from the second grid. Electrons emitted from the carbon nano-tube are collided with gas molecules to be ionized. The ionized cation is sensed by the collector to be outputted as an electrical signal.

Abstract: In the present invention, time information is sent through a common power line in executing home automation devices or using various industrial equipments. In the power line broadcasting, a small amount of data, such as time information, is transmitted unidirectionally, and long-distance power line broadcasting can be possible using carriers of a low frequency band. time setting for various instruments is automatically performed in response to a power signal after a breakdown of electric current, making unnecessary a user's action to perform the time setting, and the existing power line can be used without change.
