• the control unit controls the operation of the solenoid valve 380 in response to the detection signal.
• the solenoid valve 380 is opened while the process chamber 210 is being charged with water at the initial operation stage and while the water in the process chamber 210 is being discharged through the water discharge pipe 342 after completion of the decomposing/liquefying process, so that the air in the process chamber 210 can pass through the solenoid valve 380.

• the system control unit maintains the pressure at a constant level using the regulator 394 and the solenoid valve 396 on the basis of the measured pressure. In the case in which the pressure inside the process chamber 210 increases higher than a predetermined value, the solenoid valve 396 is opened and thus a small amount of water is released, resulting in decrease of the inner pressure.
