A fan, particularly for cooling internal combustion engines for earth moving machines, whose blades have an elastically deformable composite structure including at least one shape memory alloy foil adapted to be heated by means of electric current to vary the geometry of the blade. In a preferred embodiment, the equipment is lifted by attaching a plurality of equipment adapters to the equipment, attaching a jack assembly to each of the plurality of equipment adapters, lifting the equipment by simultaneously raising the jack assemblies, moving the transport under the equipment and lowering the equipment onto the transport. The surface of the liquid chamber member on the recording element substrate side includes a first region on which the adhesive for fixing the recording element substrate is applied; and a second region being a region other than the first region. The first connecting element is a magnetic element and is placed on one corner of the peripheral element. When the first dielectric plate and the second dielectric plate are moved in the longitudinal direction of the phase shift circuit, the overlapped areas between the intersecting parts of the signal line and the overlapping parts of the first dielectric plate and the second dielectric plate are changed.
