A method for forming gas barriers on electronic devices is provided. The cross flow fan may include a fixing member having a plate shape, and a plurality of blades fixed to one surface of the fixing member. An integrated disconnect clutch controls pump speed and a torsional damper attenuates vibrations transmitted through the housing. Then, the integrated circuit device is bonded to the glass substrate without suffering from damages by sharp edges of the glass substrate. Preferably, the angular field of observation is no smaller than 180\xb0, and in particularly preferred fashion, it is substantially equal to 360\xb0.
