A liquid transport apparatus constructed by stacking a plurality of plates includes a flow passage unit having pressure chambers, a common liquid chamber, and communication flow passages communicating the pressure chambers and the common liquid chamber, and a pressure-applying mechanism which applies a pressure to the liquid in the pressure chambers. UGA is a firmware standard, intended to wrap existing or planned hardware, including VGA. In an MRI device, a patient is subjected to a constant magnetic field, and RF pulses are used to excite the nuclei in the patient’s body, which release a corresponding RF signal as the nuclei relax, which is measured and mapped into a visual display. The closure member is movably supported in the inner sleeve in a vertical direction. The extenders may have rod interfaces that receive the rod in a manner that mimics the geometry of the pedicle screws so that the selected or configured contoured rod will properly fit into engagement with the pedicle screws.
