A nonaqueous electrolyte secondary battery is provided. The sample holder comprises a sample holder body with a sample cavity to receive the sample and a cover movably mounted to the holder body between an open position to allow access to the cavity and a closed position to seal the cavity. The high gain circuit element generates an amplified transducer signal, and the summing amplifiers sum the amplified transducer signal with a positive reference voltage and the negative reference voltage, respectively, to generate a first summation signal and a second summation signal. The string retaining chambers have an upper and lower portion corresponding with the upper and lower portions of the block. The method further includes electronically associating the context information indicative of a recognizable aspect of an item and the annotation information indicative of a user expression associated with the recognizable aspect of the item. The adhesive sheet S is cut along the outer periphery of the wafers by a cutter blade 63 mounted at the free-end side of a robot 15.
