In the image formation apparatus, an active filter converts an AC power supply supplied from an AC power supply to a DC voltage, and first and second DC-DC converters convert the DC voltage converted by the active filter to voltages at predetermined levels and respectively supplies the voltages to an image forming engine and an engine control unit. The sensor array is used to detect perturbations. Furthermore, each support member is configured to contact a respective inner portion of the glass sheet to support the respective inner portion of the glass sheet until the glass sheet has been sufficiently cooled. Based on the input of a user on a touch panel, the packs are supplied to a grouping table via a supply conveyor in a predetermined sequence. The invention further encompasses novel compounds from which sulfinamides and sulfoxides can be prepared.
