According to the present invention, there are provided a base station device, a terminal device, a communication method, and an integrated circuit capable of performing communication more efficiently when the terminal device transmits an uplink signal based on scheduling by the base station device. The opposite ends of the prongs are connected to a tubular member which, in turn is slidable within a housing connected to the pipe. The pin wheel assembly is formed with a pin wheel sandwiched between adjacent cylindrical segments and the end cap. Flood valves are located on the expellable members and, on activation, allow flooding of the tubular member by external fluid. The anode is provided with a metal fluoride layer to enhance the overall performance of the device, including higher power efficiency, lower voltage threshold and improved device operation stability. The retaining arrangement for securing the measuring arrangement to the vehicle is constructed so that the measuring arrangement can be easily separated from the retaining arrangement and used to investigate material in a stationary application.
