Abstract: An air conditioner includes heat exchangers, an actuator configured to generate pulse-type air current by vibration of a diaphragm, a manifold connected to the actuator and having a plurality of blast ports to configured to blast multiple pulse-type air currents over a large area, and a Coand{hacek over (a)} surface configured to transfer the multiple pulse-type air currents blasted through the plurality of blast ports in a long distance. Therefore, the air conditioner can be useful in reducing generation of noise and being miniaturized.

Abstract: Disclosed herein is a ceiling embedded type air conditioner having a filter cleaning device to clean a filter. The filter cleaning device includes a cleaning unit to remove dust from the filter and a dust storage unit to store the dust removed by the cleaning unit. The filter may automatically and periodically be cleaned by the cleaning unit and the removed dust may be stored in the dust storage unit, which eliminates a need to separate and clean the filter.

Abstract: A clothes dryer having a lint cleaning device to collect and store lint generated during drying through a simple structure. The lint cleaning device, including a filter, a rectilinear blade performing a rectilinear motion to collect lint, and a rotary blade performing a rotary motion interlocking with the rectilinear motion of the rectilinear blade to collect lint, collects lint at a spot and stores the collected lint in a compressed state. The lint cleaning device is used for a long time without replacement.

Abstract: A device and method for cleaning a lint filter in a clothes dryer. The clothes dryer includes an air channel connected to a drum to supply air into the drum and to guide air discharged from the drum, a dehumidification unit disposed in the air channel to condense moisture contained in the air discharged from the drum, a waterspout to collect condensed water created by the dehumidification unit, a filter to filter lint from the air discharged from the drum, a cleaning nozzle to spray water to the filter to remove the lint from the filter, a recovery water tank to receive water from the waterspout, and a cleaning water tank connected to the recovery water tank to receive water from the recovery water tank and to supply the water to the cleaning nozzle.

Abstract: A soft X-ray photoionization charger includes a housing having a chamber and an aperture formed on one side surface of the housing and joined to the chamber. The chamber forms a flow path of an aerosol containing particles. A photoionizer is fixed to the aperture of the housing. The photoionizer includes a head for irradiating soft X-rays into the chamber to neutralize the particles. A transparent window is mounted between the chamber and the head. The transparent window is made of a material permitting passage of the soft X-rays. The photoionization charger further includes a soft support ring arranged around the transparent window and tightly fitted to the aperture.

Abstract: A microactuator including a base frame; and a moving plate having both ends supported by a plurality of elastic support portions inside the base frame, the moving plate having a first side on which a reflective mirror for changing a light path is disposed. At least one first rib is disposed along an edge of a second side of the moving plate, which is the reverse side of the first side of the moving plate, and a second rib is disposed in the center of the second side of the moving plate and correspondingly encloses a permanent magnet. Also, a portion of the second side of the moving plate, except for the first and second ribs, is removed to a predetermined depth to reduce the weight of the entire moving plate and to define the first and second ribs.
