A cleaner capable of more effectively collecting dirt or dust on a complex-shaped surface or in fine portions including corner sections. The capacitor is disposed in alignment with a first direction in which the semiconductor modules are stacked. The system can be used to narrow down the angular coordinates of a transmitting satellite by emulating antenna patterns that cover portions of a search space. A peripheral edge of the middle layer may be sealed with the wall to prevent the upper and lower chambers from being in fluid communication with each other. Also, the touch sensor of the present invention does not require any adhesive for bonding to a separate substrate, which reduces its manufacturing costs.
