The purpose of the present invention is to provide a crucible which has high viscosity at high temperature, can be used for a long time, and can be manufactured at low cost, and a method of manufacturing the crucible. The loudspeaker magnet assembly includes an annular outer magnet having a top surface and the surround suspension system may include a surround suspension member. 2:1 to 50:1, and the molar ratio of e:c is in the range of from 3. If the current operating condition of the interlocking shifting element indicates that engagement of the interlocking shifting element has to be carried out and the interlocking shifting element engaged, then the interlocking shifting element is engaged andor the force flow in the transmission device is interrupted. In some embodiments, the controller is configured to receive the pass-through vendor specific command from an application software module of a host through an interface that is configured in accordance with a standard that does not allow communication to occur between the controller and the function module.
