The invention relates to plants, especially transgenic plants, plant parts and plant cells overproducing an iron binding protein and having an enhanced resistance against a wide range of abiotic and biotic oxidative stress conditions. An upper pyrometer is used to detect infrared radiation from a test layer formed on a test substrate under standard processing conditions. An audio receiver is compatible with the ear of the user and a microphone transmits words spoken by the user, electronically therethrough. An upper layer contact is provided having a portion with a generally circular interior facing edge. The carrier transfer device control section controls the carrier transfer device such that the carrier, which has been judged to be capable of a liquid processing on the basis of the result of the inspection of the wafers W, is stored in the carrier stock section, and the liquid processing is started after completion of the inspection of a predetermined number of carriers. Applications: sensors for stringed musical instruments, sensor for measuring the tension of a cable, etc.
