Disclosed is a semiconductor device which includes: a semiconductor element 200 including a first metal-insulator-semiconductor field-effect transistor 200a and a second metal-insulator-semiconductor field-effect transistor 200b which is connected in parallel with the first metal-insulator-semiconductor field-effect transistor; and a control section which controls the operation of the semiconductor element. The control section controls the semiconductor element so that in a forward direction mode, current flows in a forward direction through the first and second metal-insulator-semiconductor field-effect transistors but that in a reverse direction mode, current flows in the reverse direction through the first metal-insulator-semiconductor field-effect transistor but does not flow through the second metal-insulator-semiconductor field-effect transistor.

A molding machine includes a plurality of operating die units that are arranged in series while die opening/closing directions of the operating die units are respectively matched with each other. The operating die units can be closed and opened by a common drive source. The molding machine may further include a plurality of replacement die units that are respectively positioned adjacent to the operating die units and are arranged in a direction perpendicular to the die opening/closing directions of the operating die units, and support bases that are capable of moving the replacement die units to die operating positions in which the replacement die units can be closed and opened by the drive source. The support bases are capable of moving the operating die units in the direction perpendicular to the die opening/closing directions thereof and to shift the same in positions different from original positions of the replacement die units.

The object of the present invention is to protect completely a part of an article having penetrating hole(s) from a surface treatment. To attain said object, a masking member (1A), having fitting part(s) (11A) to fit into said hole(s) of said article, the bottom end(s) of said fitting part(s) reaching the end(s) of said hole(s), and flange(s) (13A) being formed around bottom end(s) of said fitting part(s) around the circumference(s) of said hole(s), is provided. When said masking member (1A) is attached to said part by fitting said fitting part(s) of said masking member (1A) into said hole(s), the bottom end(s) of said fitting part(s) of said masking member (1A) reach(s) the opposite side(s) of said hole(s), and flange(s) (3A) around the bottom end(s) of said fitting part(s) of said masking member (1A) cover(s) circumference(s) of said hole(s), to protect the inside(s) of said hole(s) from paint mist circulating around said article, and from reaching the opposite side(s) of said article, when said article is being spray coated with paint.
