A cutting apparatus includes a handle frame, a cutting blade, and a blade rotation arrangement. A plurality of bar-shaped members formed of an evaporative material and a plurality of connecting members formed of an evaporative material are prepared. As such, when the triggering event defined by a callback trigger is detected during consumption of the electronic document by an end user, a corresponding callback action is performed. The x-ray tube can be mounted in a manner that it can pivot, allowing it to move and align itself. This semiconductor epitaxial structure can be used in a semiconductor light-emitting device to obtain high emissive efficiency and an operating characteristic that remains linear into the high current injection region. The head suspension 31 properly maintains electric insulation between the piezoelectric element 13 and the attaching part, sufficiently demonstrates original functions, and secures a rigidity balance and proper vibration characteristic.
