Abstract: Provided is a high-efficiency slim vacuum inhalation apparatus which cools heat generated from heat-generation sources without using particular heat radiation components, and a robot cleaner employing the same. The vacuum inhalation apparatus does not need particular heat radiation components since an impeller is closely adhered to a rotational shaft by a pair of washers and an impeller bushing, to thus avoid from sliding, and since an inhalation efficiency which is caused by a brushless direct-current (BLDC) motor increases, and thus power consumption decreases. Further, since a BLDC motor is incorporated in a vacuum inhalation apparatus so that the vacuum inhalation apparatus can be implemented into a slim type, a robot cleaner can be also compactly realized into a slim type.

Abstract: Provided are a radial core type brushless direct-current (BLDC) motor and a method of making the same, having an excellent assembly capability of division type stator cores in a double rotor structure BLDC motor. The BLDC motor includes a rotational shaft, an integrated double rotor including an inner rotor and an outer rotor, and a rotor supporter wherein a trench type space is formed between the inner rotor and the outer rotor, and an end extended from the inner rotor is connected with the outer circumferential surface of a bushing combined with the rotational shaft, and an integrated stator wherein one end of the stator is disposed in the trench type space and an extension axially extended from the other end of the integrated stator is fixed to the housing of the apparatus.

Abstract: Provided are a stator for an aspiration motor, an aspiration motor and an in-car sensor using the same, in which a bobbin is integrally formed with a stator, to thus use an inexpensive insulation wire and enhance a productivity and lower an inferiority using an insert-molding technology. The stator for the aspiration motor includes a stator support plate, a support boss which is vertically extended from the central portion of the stator support plate, a bobbin which is bent and formed on the lateral surface of the support boss, and which is separated from the upper side surface of the stator support plate, to thereby provide a space, and a stator coil which is formed by making a wire wound in the space provided by the bobbin.

Abstract: Provided is a driving device for a full automatic washing machine in which a clutch unit can stop rotation of a dehydration axis without having a particular brake unit, since the clutch unit is closely adhered to a first dehydration axis and a bushing when the rotation of the dehydration axis is controlled according to a wash or dehydration stroke in a full automatic washing machine. In addition, since a clutch coupler of the clutch unit moves at a wash or dehydration stroke in a driving device of a washing machine to thus be attached to and detached from a clutch gear which controls rotation of the first dehydration axis, and to thereby control a rotational force which is transferred to an inner tub, the washing machine is embodied to have a simple clutch coupling structure.

Abstract: An optical device such as an LCD has a package of optical films positioned between a backlight and a display panel for enhancing the optical performance of the device. The package of optical films includes a first layer and a third layer and a second layer disposed between the first and third layers. The second layer is smaller than the first layer, so that the second layer covers a first region of the first layer but not a second region of the first layer. The third layer is attached to the second region of the first layer. In some embodiments the first layer has a structured surface facing the second layer. In other embodiments, the second layer has a structured surface facing the third layer. In other embodiments, both the first and second layers have structured surfaces facing the third layer.

Abstract: Directly illuminated liquid crystal display (LCD) units include an LCD panel, a backlight cavity, an optical film stack located between the LCD panel and the backlight cavity, and a supporting structure. The supporting structure, which is relatively low-profile and lightweight, is positioned to maintain the optical film stack in a substantially flat condition. In some cases, the supporting structure includes a flexible support such as a film, a filament, or an array of filaments that are held taut in at least one dimension. In some cases, the supporting structure includes a rigid elongated support that covers only a portion of a useful area of the film stack.
