An air conditioner includes an inlet; a suction channel through which air sucked from the inlet flows; a spray unit configured to spray water to be vaporized; a first channel through which first air to be cooled by heat of vaporization of water sprayed from the spray unit flows; a heat exchanger configured to exchange heat between the first air and the air flowing through the suction channel to cool the air flowing through the suction channel; wall body defining the first channel located downstream of the heat exchanger in a flow direction of the first air; and an electric device configured to generate heat with power consumption by the air conditioner. The electric device is thermally connected to the wall body.

Air conditioner

An air conditioner includes a housing having a first outlet and a second outlet, a first channel communicating with the first outlet, a second channel communicating with the second outlet, a tank unit configured to hold water for cooling first air and second air, the first air flowing through the first channel, the second air flowing through the second channel, a cooling unit configured to cool the first air by heat of vaporization of water held in the tank unit, a water supply channel for supplying water held in the tank unit to the cooling unit, and a water recovery channel for collecting water remaining in the cooling unit to the tank unit.

A suturing device includes first and second holding members, a plurality of needles, a needle moving mechanism, and a suture hook. The first and second holding members are configured to move toward and away from each other to sandwich therebetween edges of a cut. The needles are disposed at the first holding member and aligned in a needle arrangement direction with their points pointing to the second holding member. The needles are configured to hold a suture at tips thereof. The needle moving mechanism is configured to move the plurality of needles toward the second holding member. The suture hook is disposed at the second holding member and configured to move along the needle arrangement direction to catch the suture that has reached the second holding member via the edges of the cut by movement of the needles toward the second holding member by the needle moving mechanism.

Suturing device

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

Vibration-powered generator

A vibration energy generator includes a case, a coil, a permanent magnet, and a shield magnet. The case is elongated in one direction and is made from a nonmagnetic material. The coil surrounds around an outer surface of the case. The permanent magnet reciprocates inside the case along the one direction. The permanent magnet is magnetized with a polarity oriented in the one direction. The shield magnet is disposed in one end portion of the permanent magnet in the one direction. Each of a surface of the one end portion and a surface of the shield magnet facing the surface of the one end portion has the same magnetic polarity. The length of the shield magnet in the one direction is less than the length of the permanent magnet in the one direction.
