Provided is a method for inactivating a pathogenic microorganism even in the presence of an organic substance in a simple manner and with high reliability while reducing the burdens on the environment. An aqueous medium containing a pathogenic microorganism and an organic substance is treated by adding an active oxygen donor, chlorine dioxide and an active oxygen donor sequentially to the aqueous medium, thereby inactivating the pathogenic microorganism in the aqueous medium.

A gas fire-extinguishing apparatus according to an embodiment of the invention is configured such that a silencer is disposed on an ejection head which ejects fire-extinguishing gas supplied from a fire-extinguishing gas supply source via a conduit pipe, a diverging pipe and a branch pipe. The configuration suppresses ejection sound caused by an ejection flow of the fire-extinguishing gas.
A gas fire-extinguishing facility is configured in such a manner that a noise reducing device (17) is provided to a discharge head (13) for discharging a fire-extinguishing gas which is supplied from a fire-extinguishing gas supply source (15) through a conduit pipe (14), a dividing pipe (18), and a branch pipe (19). The configuration reduces the discharge noise caused by the discharge flow of the fire-extinguishing gas.

ODOR GENERATION ALARM AND METHOD FOR INFORMING UNUSUAL SITUATION
Provided is a high-security odor generation alarm exhibiting a strong action of attention calling. Also provided is a method for informing an unusual situation. An odor generation alarm (1) comprises an odorant container, a drive section (10), a detector (4) and a circuit section (7) working as a control section. The odorant container contains an odorant. The concentration of an odorant in the air which gives off odor intolerable to a human being is lower than the maximum non-action concentration of the odorant. The drive section (10) drives out the odorant from the odorant container . The detector (4) detects occurrence of an unusual situation and outputs a detection signal. The control section receives the detection signal from the detector and controls the drive section to discharge the odorant in response to the detection signal.
A smell outbreak alarm which can secure certainty of discharge operation and diffusibility of smell. Upon receiving information indicating occurrence of abnormal state from a sensor (4) for detecting occurrence of abnormal state, the smell outbreak alarm (1) operates an initiator (9) by a circuit section (7). The initiator (9) displaces the piston (19) of a drive section (10) and displaces a spray can (11) for the casing (12) and switches the spray can (11) to discharge state thus discharging smell liquid filling the spray can (11) while atomizing.
A method for controlling a respirator having a gas supply mechanism controlled with a stability having an increased margin. The flow F of an assist gas is measured, and an estimated flow ^F of the assist gas is determined by an observer (54). The flow difference F between the measured flow F and the estimated flow ^F is determined. Information on the spontaneous respiration pressure Pmus of a patient is collected, and a target pressure Pin to control the gas supply mechanism (20) is computed from the information. By thus computing the target pressure Pin from the flow difference F and adequately selecting a parameter by a regulation transfer function, the margin of the stability limit of the entire system (14) can be increased. Hence, even if the actual entire system varies, a run-away hardly occurs. Compared to the conventional PAV type, the assist response can be improved.
