A ceramic heater capable of reducing temperature uniformity at the periphery of through holes such as insertion holes and vacuum suction holes is provided, which protects wafer against thermal shocks and has improved controllability for temperature control parts such as thermocouples and temperature fuse. In an illustrative embodiment of the invention, the analyte is a drug, such as marijuana, cocaine, methamphetamine, methyltestosterone, or mesterolone. A testing section is disposed along the conveyor upstream from the battery feeding section for testing the electrical condition of the batteries as they move along the conveyor. In this way, a robust and reliable measuring operation is guaranteed, which is little influenced by oscillatory in-couplings. Embodiments detect an error condition has been satisfied at a first one of the plurality of processing elements, wherein the first processing element contains a plurality of fused operators. The composite member has a projecting portion at which a peripheral edge of the first member projects outside a peripheral edge of the second member.
