A non-contact IC card readerwriter device includes antennas that perform carrier wave transmission and reception with a non-contact IC card, an AD converter that detects the voltage level of each carrier wave received from the non-contact IC card through the antennas, and a control unit that calculates the location of the non-contact IC card from the voltage levels detected by the AD converter. The drain plug housing further comprises a first threaded aperture having a first diameter terminating at the interior of the oil pan and a second threaded aperture having a second diameter greater than the first diameter, with a hollow cavity therein between. When the pressure difference between the pressure measured by the pressure sensor and the target pressure is larger than a predetermined pressure difference, the control section corrects operating conditions of the compressor, so that the measured pressure becomes the target pressure. Each of the RFID circuit elements To has an IC circuit part for storing information and an antenna connected to said IC circuit part. The EI24 mRNA was also induced in a p53-dependent manner by ionizing irradiation of primary murine thymocytes. The surface layer is grown by anodizing at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange.
