The present invention relates to a mutant of Monascus purpureus NTU 568, a nucleotide sequence for Monascus purpureus NTU 568 and primers for nucleotide sequence of Monascus purpureus NTU 568, wherein the Monascus purpureus NTU 568 having the nucleotide sequence of SEQ ID NO 1, SEQ ID NO 2 or SEQ ID NO 3 is deposited with Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH on Nov. The upper frame and the lower frame are adjustable relative to one another in at least one of a linear and rotational manner. The group intersects with the diagonal line if the surface is viewed from the sensor toward the shaft, and a position of the intersection changes according to rotation of the case around the axis when viewed from the shaft. A lower insulator is disposed between the support structure and a plate allowing the lower insulator to interact with the bottom and cylindrical skirt of the support structure and the plate to isolate forces in a vertical andor lateral direction.
