Compounds such as 4-methylcholest-7-en-3-ol, 4-methylergost-7-en-3-ol and 4-methylstigmast-7-en-3-ol which have an activity for improving pancreatic function are used as an active ingredient of a pancreas function improving drug and food or drink. The additive comprises solid colloidal particles coated with a dispersant during the comminution process of forming the particles. In some embodiments, the scheduling may result in increasing or maximizing the throughput of slides. The transition from one of the regulation ranges to a respective adjacent regulation range is achieved through an overmodulation of the pulse-to-width modulation and a limitation of the outputs from current regulators of the stator winding of the electrical machine. The user experience in performing inventory management is simplified and enhanced over existing methods. The saving is substantial as the current sensors will not drain a current when the AC outlets are disconnected from a load or when the load is switched off.
