摘要： A mixed gas supply device includes: a hydrogen gas generation unit that includes a hydrogen generator, the hydrogen generator generating hydrogen gas by decomposition of water and supplying the hydrogen gas; a nitrogen gas generation unit that includes a filter, the filter separating nitrogen gas from air and supplying the nitrogen gas; a gas mixing unit that mixes the supplied hydrogen gas and the supplied nitrogen gas and generates mix gas including the hydrogen gas and the nitrogen gas; and a single base on which the hydrogen gas generation unit, the nitrogen gas generation unit, and the gas mixing unit are mounted, the hydrogen gas generation unit, the nitrogen gas generation unit, and the gas mixing unit being integrated. The gas mixing unit supplies the generated mixed gas to outside.

摘要： A wheeled tire includes a tire, and a wheel disposed on the tire. A space between the tire and the wheel is filled with a filler gas. The filler gas includes nitrogen gas having a concentration equal to or greater than a concentration of nitrogen gas in air, and hydrogen gas having a concentration of 0.5% or more. A concentration of oxygen gas in the filler gas is less than a concentration of oxygen gas in air.

摘要： There is provided a gas sensor fault detection device that detects a sensor fault in a gas leak inspection device. The gas sensor fault detection device includes: a gas blowing unit that blows a gas toward a detection area of a gas sensor of the gas leak inspection device; and a position fixing unit that fixes a position of the gas blowing unit with reference to a hypothetical gas leak position of an inspection target being inspected by the gas leak inspection device.
