Abstract: A nebulizer includes: a suction mechanism configured to suck a liquid for humidification from a water bottle containing the liquid and form an aerosol of the sucked liquid by a negative pressure produced by an oxygen gas jetted from a gas jetting part of a nozzle member; a liquid receptor configured to store the liquid residing in the form of droplets into which the aerosol turns; and a receptor-side aerosol forming member configured to suck the liquid from the liquid receptor and form an aerosol of the sucked liquid by the negative pressure. Consequently, germs are prevented from getting into the liquid in a container during use, and the liquid is prevented from dripping when the container is replaced.

Abstract: Appropriate performance design of various mechanisms, e.g. a mist removing filter, employed in post-paint treatment of various mechanisms, e.g. a deodorizer, employed in post-dry treatment is realized. Paint weight calculation is executed. Firstly, the amount of dry adhered paint is calculated by multiplying the work area by a coating thickness distribution value and stored, and the weight of dry adhering paint is calculated by multiplying the amount of dry adhering paint by the specific gravity of the dry paint and stored. Meanwhile, the weight of dry paint or the weight of dry paint sprayed from a paint machine is calculated by multiplying the weight of sprayed paint by a paint NV and stored, the weight of dry non-adhered paint is calculated by subtracting the weight of dry adhering paint from the weight of dry sprayed paint and stored, and then capacities of various mechanisms are designed using it.
