A conveying system for material samples, especially medical samples, comprising a conveyor track forming at least one conveying section and at least one self-propelled sample holder displaceable along the conveying section holding a sample vessel. An adsorbent capable of adsorbing moisture from the air and desorbing the moisture into the air is supported on the surfaces of the fin set, the framework, the heat transfer tube and the connector tube, respectively. Furthermore, the ECC circuit performs third error correction on the result of the second error correction using a third error correction code. An interface between the output of the driver and the input of the receiver operates according to a set of one or more timing parameters, wherein the input termination, the output termination, and the set of timing parameters correspond to a bandwidth for data transfer or frequency for data transfer across the interface between the output of the driver and the input of the receiver. A second insulating layer is then formed on a surface of the first insulating layer while covering the gate electrode pattern. As thus formed, the high-side integrated circuit and the low-side integrated circuit can be formed without termination regions and without buried layers.
