Process and apparatus for laying fiber bands of filaments by changeably moveable weft or diagonal layers to form fiber arrangements stretched in different laying directions between two transport chains having guide hooks and retainer needles. The device includes a shunt at least partially enclosed in a conduit, a portion of the conduit being collapsible or inwardly deformable to control, reduce, or prevent fluid flow. The nozzle arrangement also includes a thermal actuator cantilevered on the wafer substrate so that the actuator partitions the nozzle chamber, the actuator having a heater layer which produces thermal expansion of said actuator upon activation, thereby ejecting ink from the nozzle chamber via the ejection port. The position designator 110 determines the displayed position of the child-frame video in accordance with displayable time information of the child-frame video and information on the displayed area or displayable area depending on time, included in the data for display. The collected media is stored on a database which accessible by the user using an access identifier. As the bicycle begins to ascend a slope the attachment member retracts to maintain the track in ground contact and as the bicycle begins to descend the slope the attachment member extends to maintain the track in ground contact.
