A method for cleaning deposits of particulate material from the tip of a nozzle of a dispensing apparatus, such as, for example, the tip of the nozzle of a liquid reagent dispensing apparatus. In one method, potentially defective properties are enumerated for a board, without regard for how the potentially defective properties might be tested. By comparing the extracted objects with objects included in the plurality pieces of style information that are registered on the registration unit, style information to be output is selected. The first inverter includes a first n-type metal oxide semiconductor transistor having a first n-type threshold voltage and a first p-type MOS transistor having a first p-type threshold voltage.
