A sparing device comprising of a liquid storage tank for storing liquid and a spraying mechanism for spraying the liquid from the liquid storage tank through a nozzle. A storage box is provided having first and second lid sections. The transmitting device may include a transfer count unit to maintain a data transfer count based on a number of transmitted data bytes. When multiple such neighbors are grouped together they can be used to indicate relevance in current data under consideration on a same or different computing device. As a result, when the piezoelectric element laminate 20 expands to seat the diaphragm valve 11 on a valve seat 10, the valve spring 29 is compressed and repulsing force of the valve spring 29 acts on the diaphragm valve 11 through the piezoelectric element laminate 20 and the diaphragm valve 11 is pressed against the valve seat 10 by the repulsing force.
