The pharmaceutical use of lipases related to the Thermomyces lanuginosus lipase comprising amino acids 1-269 of SEQ ID NO: 2, optionally in combination with a protease andor an amylase. The field of the semiconductor wafer may be located at an edge of the wafer, such as the lower-left or upper-right edge of the wafer, and is exposed using a full-image mask, such as a positive photoresist mask, and that can be inclusive of the alignment mark. Each of the hollow-bodied rebar supports has a support arm which supports the horizontally-positioned rebar. A control unit, after all of the metal pieces having various sizes and shapes are melted, causes the operation of the inverter to continue for a first time period and, after that, to suspend the operation of the inverter for a second time period so that the heating can be stopped. The elastic body connects the fixed support with some rods thereof and connects with the electrostatic vibrating body with some other rods thereof.
