The present invention aims at providing a method of screening a gene that controls the production of amyloid protein. The spindle 4 comprises a first spindle part 402 for rotation about its longitudinal an axis by means of a motor and having an inwardly directed rim 406, and a second spindle part 404 for supporting a drill bit of the hammer drill and having an outwardly directed rim 410. Upon receiving the fault signal, an interconnection relay is opened to cancel the interconnection and simultaneously, a timer is started. In some embodiments, mapping the device-oriented digital rights to digital rights supported in the cluster includes supporting in the cluster only those device-oriented digital rights having direct analogs in the cluster.
