The present invention relates to an adjustable spanner having a first fixed jaw and a second moveable jaw. The slide module includes a tilting unit configured to tilt the first body with respect to the second body at a predetermined angle in the open configuration and a slide member configured to slidably connect the first and second bodies to each other. A carrier fluid, such as a gas, is then directed toward the semiconductor substrate so as to move the resist stripper across the substrate. The image forming apparatus also includes an emission controller for controlling the ink emission from the ink emitting openings formed in the ink emitting surface. 6% by mass or less of Si; and 0. The semiconductor device comprises one or more transmission and reception coil pair, each pair comprising a single transmission coil and a plurality of reception coils, or a plurality of transmission coils and a single reception coil, or a plurality of transmission coils and a plurality of reception coils.
