Abstract: ABSTRACT OF THE DISCLOSURE     A supporting insulator     to support the driving mechanism     of a disconnect switch part       and a supporting insulator     of a breaker      are unified. The heights of the fixed contact     and the driving mechanism     of the disconnect switch part       as well as the height of the upper end of the common supporting insulator     supporting the breaker      are substantially the same.  Setting area is thus decreased, while ensuring a high spatial insulation distance.

Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus for acoustic wave generation and transmission into a subsurface earth formation.  A logging sonde adapted to be suspended in a borehole within the formation houses a generator means for simultaneously generating a plurality of acoustic waves traveling in the direction of and spaced substantially evenly about the longitudinal axis of the sonde.  An acoustic energy reflector means within the housing reflects the waves radially outwards of the axis and into the formation at angles generally perpendicular to the axis.          Detectors within the housing spaced longitudinally from the generator and reflector detect acoustic energy in the formation resulting from the reflected waves.  In a preferred embodiment, the generator means comprises four cylindrical magnetostric-tively energized elements disposed about the central axis of the sonde, each having an axis parallel to the central axis, so that the four axes of the elements, when viewed in the direction of the central axis, define four corners of a square.  The elements are designed so that upon energization, a given element vibrates longitudinally out of phase relative to the two elements adjacent thereto, vibration of the four elements in concert generating two positive and two negative waves which, when reflected into the formation, interfere to produce a quadrupole shear wave.
