Abstract:
A suction body for a cleaner is provided that can generate electric energy by itself using air drawn in by the cleaner. A suction body includes an ultraviolet sterilizer that radiates ultraviolet rays toward a surface to be cleaned and sterilizes the surface to be cleaned, a lighting device that emits light, a displaying device that displays a cleaning state, a fan that rotates by drawn-in air, and a generator that converts rotary energy of the fan into electric energy so as to supply the electric energy to the ultraviolet sterilizer, the lighting device, and the displaying device.
Abstract:
A suction port assembly and vacuum cleaner having the same is disclosed. The suction port assembly includes a casing comprising a suction port which draws in dust from a surface being cleaned; a drum brush which is disposed rotatably in the casing, on an external surface of which a plurality of bristles are arranged to shake off dust from the surface being cleaned; and a rib which is disposed at a position close to the drum brush, is mounted in the casing so that its one end is in contact with the bristles, and detaches the dust from the bristles when the drum brush rotates; and wherein the bristles are contacted on a slant relative to the rib to prevent the drum brush from rotating when the casing is pulled towards a user.
Abstract:
A vacuum cleaner includes a vacuum cleaner body, a cyclone unit which is mounted at the vacuum cleaner body, and separates dust from drawn air, a dust separating unit which is engaged with a lower end of the cyclone unit, said dust separating unit being configured to collect separated dust, said dust separating unit being detachable from the cyclone, and said dust separating unit comprising a compressing plate compressing the collected dust; and a driving unit which is disposed at a lower end of the dust separating unit, said driving unit being configured to ascend and descend the dust separating unit to be detachably connected to the cyclone unit and drives the compressing plate. As a result, the vacuum cleaner is capable of not only compressing dust in a dust separating unit by rotating a lever, but also detachably mounting the dust separating unit to a cyclone unit. Therefore, the vacuum cleaner having simplified structure and a convenient operation is provided.
Abstract:
A cyclone dust collector comprises a cyclone body including a cyclone chamber, a connection path and a dust chamber, wherein the cyclone chamber and the dust chamber are arranged in parallel, a cover unit connected to an upper part of the cyclone body and having a suction path for external air to flow in therethrough, and a backflow prevention member disposed at one sidewall of the dust chamber to prevent collected dust from flowing to the cyclone chamber.
Abstract:
Provided are a dielectric film, a method of manufacturing the same, and a semiconductor capacitor having the dielectric film. The semiconductor capacitor includes a lower electrode, a ferroelectric layer disposed on the lower electrode, a paraelectric layer disposed on the ferroelectric layer, and an upper electrode disposed on the paraelectric layer.
Abstract:
A mobile communication device includes a side key having at least three buttons disposed on the side of a device body. Each button of the side key has at least two functions assigned differently and independently according to operation mode and key press time. In a method for controlling the side key, at least two functions are assigned to the side key. Receiving a press input from the side key, a control unit determines a key setting type corresponding to the received press input. Then the control unit retrieves a function corresponding to the determined key setting type from the assigned functions, and then performs the retrieved function of the side key.
Abstract:
A delay locked loop for generating an internal clock signal locked to an external clock signal includes: a phase detector for detecting a phase difference between the external clock signal and the internal clock signal; a delay unit controller for generating a control signal and a selection signal in response to an output signal of the phase detector; a variable delay device (VDD), responsive to the control signal and a selection signal, to produce a delayed version of the external clock signal on a VDD output line, the variable delay device being configured such that, if the external clock signal undergoes a change from a first frequency to a second frequency significantly different than the first frequency, then a resultant load on the VDD output line nonetheless remains substantially the same.
