A disinfecting and virus inactivating device performs disinfection treatment or inactivation treatment in a target space that a moving body enters and exits. The disinfecting and virus inactivating device includes a locus detection module configured to detect a movement locus of locations where the moving body comes into contact with respective objects or respective portions of an object in the target space, a substance generating module configured to generate a particular substance for use in the disinfection treatment or the inactivation treatment, and a transmission module configured to generate an air flow and transmit the particular substance generated by the substance generating module to the movement locus.

An air cleaner includes: a generation unit configured to discharge an electric current by being applied with a high voltage, and generate a plurality of types of discharge products; an air-sending device configured to form a flow of air, and spray the plurality of types of discharge products generated from the generation unit to a space; an estimation unit configured to estimate an amount of dust floating in the space by selecting whether an amount of dust floating in the space is a first estimation amount smaller than a predetermined threshold or is a second estimation amount larger than or equal to the predetermined threshold and larger than the first estimation amount; and a control unit configured to control a generation amount of the plurality of types of discharge products to be generated from the generation unit based on the amount of dust estimated by the estimation unit.

A water treatment device generates a bubble in water to be treated inside a treatment tank, and treats the water to be treated through use of radicals that are generated by bubble electric discharge caused via the bubble. The water treatment device includes main electrodes for forming a main discharge area between a first main electrode and a second main electrode, auxiliary electrodes for forming a preliminary discharge area between a first auxiliary electrode and a second auxiliary electrode, and a bubble generator generating a bubble in water to be treated through use of an externally supplied gas. When a bubble generated by the bubble generator passes through the preliminary discharge area, discharge is caused via the bubble, and, when the bubble in an excited state subsequently passes through the main discharge area, the bubble causes discharge again to generate radicals.

A light guide including a light scattering portion that reflects light guided inside the light guide, and a light emitting surface portion emitting light reflected by the light scattering portion to outside the light guide. A light emitting surface portion includes first and second light emitting surface portions, the first light emitting surface portion has a longer circumferential length than that of the second light emitting surface portion in the transversal cross section, and circumference curvature of the first light emitting surface portion in the transversal cross section increases away from the second light emitting surface portion. A normal line to the light scattering portion, passing through the center of the light scattering portion in the transversal cross section, intersects with the first light emitting surface portion, at a point at a near side to the second light emitting surface portion in the transversal cross section.
