A method for fabricating a copper indium diselenide semiconductor film using a self cleaning furnace is provided. The non-relational database object may then be mapped into a relational database model, such as a model associated with a business intelligence platform. Since the motor 3 is a three phase motor, an utilization efficiency of coils is higher, which decrease a heat generation of a stator 38. The front cover opens and folds at the rear of the container to form a stand that holds the container upright to display the gift object. The present invention also provides cutaneous array electrodes that may be used non-invasive to stimulate the vagus nerve.
