摘要： A fuel-cell system is advantageous for repressing water from flowing backward from a reservoir to a condenser, flowing backward which results from the inside of the condenser being turned into negative pressure. The fuel-cell system has a fuel cell for generating electric power by reactant gas, a condenser for generating condensed water by condensing water content included in the reactant gas to be supplied to the fuel cell or in off gas of the reactant gas, and a reservoir for reserving the condensed water collected at the condenser. A drain valve is disposed between the condenser and the reservoir. The drain valve is switchable between a closed state in which communication between the condenser and the reservoir is shut off and an opened state in which the condenser is communicated with the reservoir to discharge the water in the condenser to the reservoir. A controller carries out inner-pressure increment and drain controls for opening the drain valve after increasing inner pressure in the condenser.

摘要： A presentation system includes a screen device, a projecting device that projects a visible image onto the screen device, and a laser pointer operated by a user, that projects a laser beam onto the screen device. The laser pointer includes an infrared light emitting section and a laser beam emitting section. A projected image of the infrared light projected onto the screen is sensed by an infrared light sensing section. Movement direction and movement distance of the projected image and button click signal are converted into mouse data usable by computer. An image based on the mouse data from the computer is projected from a projector to the screen. A human body sensor which senses heat of human body existing in a projected direction of the laser beam is settled to supply a safe presentation system by controlling the projection of the laser beam in case this sensor is operated.
