An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.

Air cleaning module

An air cleaning module includes a filter, an air blower spaced apart from the filter to provide a fluid to the filter through a blowing port, a light source unit provided between the air blower and the filter to provide a light to the filter, and at least one guide provided between the air blower and the filter to guide a flow path through which the fluid flows. The guide guides a width of a passage of the fluid to become wider toward the filter.

A mobile communications terminal using a multi-functional socket and a method thereof, the mobile communications device comprising a connector capable of connecting the mobile communications device to at least one external device for establishing an electrical connection between the at least one external device and the mobile communications device; a switching unit; and a controller cooperating with the connector and the switching unit to perform, sending and/or receiving at least one signal with respect to the at least one external device via at least one dedicated path according to at least one identification signal; and generating a control signal to control the at least one signal, wherein the at least one signal comprises at least one of a power signal and data.

A hard disc drive includes a base having a moving region in which an air damping ramp adjacent to a recording surface of a disc, a slider, and a driving unit which holds the slider, move. A bottom of the moving region is lower than the air damping ramp, and has a channel that is recessed at the bottom of the moving region and extends along a moving path of the slider. Thus, the hard drive reduces a vortex that forms around a head gimbal assembly (HGA) due to an application of insufficient preload onto HGA or a defective HGA. Accordingly, vibration of the HGA due to the vortex decreases, thus rendering a position error signal (PES) more accurate and reliable.
