A UV emission device includes an irradiator, a control unit, a determiner, and an exposure amount output unit. The irradiator irradiates a predetermined irradiation area in a predetermined space with ultraviolet rays. The control unit controls the irradiator based on a total exposure amount of a target person to ultraviolet rays. The determiner performs a determination process of determining whether or not the target person is present in the irradiation area. The exposure amount output unit outputs an amount of exposure of the target person to ultraviolet rays based on a determination result of the determiner and operation information on the irradiator. The control unit adds the amount of exposure of ultraviolet rays to the total exposure amount of ultraviolet rays in order to update the total exposure amount.

A correcting system includes an acquisition unit, a storage unit, and a correction unit. The acquisition unit acquires information indicating first capture efficiency of a filter for first microscopic particles. The storage unit stores correction data to correct the first capture efficiency to second capture efficiency of the filter for second microscopic particles. The correction unit corrects the first capture efficiency acquired by the acquisition unit to the second capture efficiency based on the correction data.

Correcting system, and correcting method

A shaft member has the same polarity as discharge electrodes. Each of the discharge electrodes has an electrode body and a tip end which is formed at an end of the electrode body facing an inner peripheral surface of a counter electrode. The discharge electrodes extend such that the tip ends and the electrode bodies are misaligned with each other in an axial direction of the shaft body. A streamer discharge travels from the tip ends of the discharge electrodes toward the inner peripheral surface of the counter electrode.

Electric discharge device and air purifying device

A discharge unit includes a discharge electrode, a counter electrode opposed to the discharge electrode, and an insulation member having a surface. The surface is continuous from the discharge electrode to the counter electrode. A wall portion is provided on one side with respect to a discharge region formed by the discharge electrode. The wall portion is configured to suppress a contaminant from adhering to the surface of the insulation member.
