Abstract: PURPOSE:To prevent the sensitivity due to a noise occurring due to a displaying operation from being lowered by stopping the displaying operation of a message during the operation period executing the reception processing in response to the arrival of a desired signal. CONSTITUTION:For a displaying control circuit 25, an intermittent reception operation signal (a) is inputted through an inverting circuit 26, only while both intermittent reception operation signal (a) from the inverting circuit 26 and displaying control signal from a decoder 17 become 'H', the displaying control circuit 25 sends a signal to execute the displaying operation to a central processing unit(CPU) 27, drives an LCD 28 and displays the message. When a time-up signal showing the prescribed time passage is inputted from a timer 32, the decoder 17 makes the displaying control signal to the displaying control circuit 25 into 'L'. Accordingly, when the displaying of the message by the LCD 28 is executed when the intermittent reception operation signal (a) outputted from the decoder 17 becomes 'L', namely, outside the reception operation period, and the displaying is executed only for the prescribed time by the timer 32. In such a manner, the lowering of the receiving sensitivity is prevented.

Abstract: PURPOSE:To remove radioactive particles and an iodine by providing a filter device to remove the radioactive particles and the iodine contained in a vent gas, in case that the radioactive particles and the iodine contained in a backwashing water are separated freely and intrude into a compressed air. CONSTITUTION:On an occasion of a backwashing operation, an inlet valve 2V and an outlet valve 3V are closed, while an air pressurizing valve is opened with regulating its opening degree so as not to pressurize exceedingly a bearable pressure of a filter media in a filter 1, and then feed air valves 5aV and 5bV of the first branch pipe 5a and the second one 5b in an air feed piping 5 are opened.
