A Schottky diode is fabricated by a sequence of fabrication by a sequence of fabrication steps. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention. The character variant is a variation of a character in a set of variations of the character such that each variation of the character in the set is represented by a unique Unicode code point. The work sheet conveying device has work sheet holding means 20 capable of holding a work sheet W2, and moving means having a function of moving the work sheet holding means 20 parallel to a position switching direction corresponding to a direction in which the trays are drawn out.
