Abstract: An air purifier includes a housing having an air inlet, an air outlet, and a cavity portion connecting the air inlet and the air outlet, two blowers disposed in the cavity portion and each including a fan rotatable to generate a flow of air, and a filter disposed in the cavity portion. During rotation of the fan, the two blowers each suck in air from outside of the housing through the air inlet into the cavity portion, and blow the air having passed through the filter from the air outlet to the outside of the housing. A direction in which the air inlet is open crosses a direction in which the air outlet is open. An opening area of the air outlet is smaller than an opening area of the air inlet.

Abstract: A vibration-powered generator (100) has a vibrating element (10) and a coil (40) arranged therearound, and is configured to obtain electromotive force by moving the vibrating element (10) relatively to the coil (40). The vibrating element (10) has a plurality of magnets (20a to 20d) arranged so as to oppose the pole-faces of the same polarity; end supporting portions (12, 13) which support the plurality of magnets from both ends in the direction of arrangement; and a cushioning (16). The cushioning (16) is held between the end supporting portion (12) and the magnet (20c), while being compressed under a stress exceeding the repelling force between the pole-faces of the magnets, so as to keep the magnets (20a to 20d) in a row without leaving a gap in between, overcoming the repelling force.
