摘要:
A suction brush for a vacuum cleaner including a body, the bottom side of which is formed with a suction port; a cover for covering the top side of the body; and an air jetting path for absorbing ambient air from the bottom side of the body and jetting the air toward a surface to be cleaned, to space the bottom side from the surface to be cleaned.
摘要:
A suction nozzle of a vacuum cleaner includes jet units for jetting air into positions where air streams collide with each other as air is drawn into a suction port of the nozzle from both side portions thereof, so as to prevent substantially the collision of air streams.

A backlight unit and method of use are provided having a first light guide plate, a linear light source disposed along at least one side edge of the first light guide plate, a plurality of second light guide plates facing the first light guide plate, and a point light source disposed along at least one side edge of each second light guide plate. Accordingly, the present invention can provide a backlight unit using both a point light source and a linear light source at substantially the same time, and having superior color reproducibility and low power consumption.

A vacuum type pickup apparatus may include an absorption pad having an absorption inlet for contacting and/or picking up an object. A pad holder may be connected to the absorption pad. The pad holder may also have a vacuum line. A separator may be provided in the pad holder for forcibly releasing the object from the absorption inlet of the absorption pad. During the forcible release of the object, the air around the absorption pad may be drawn into the pad holder, thus reducing or preventing the potential contamination by impurities of the object as well as the equipment around the object. Also, an additional vacuum extinguisher may not be required, thus simplifying the structure of the vacuum type pickup apparatus and reducing installation costs. Furthermore, the object may be picked up and released in a relatively expedient, safe, and accurate manner, despite the suction force of the vacuum that may be maintained in the pad holder.

A complementary metal-oxide-semiconductor image sensor may include: a semiconductor substrate; a photodiode formed on a first portion of the semiconductor substrate; a transfer gate formed on the semiconductor substrate, near the photodiode, to transfer optical charges accumulated in the photodiode; a floating diffusion area formed on a second portion of the semiconductor substrate, on an opposite side of the transfer gate from the photodiode, to accommodate the optical charges; and/or a channel area formed under the transfer gate and contacting a side of the photodiode to transfer the optical charges. The transfer gate may be formed, at least in part, of transparent material. A method of manufacturing a complimentary metal-oxide-semiconductor image sensor may include: forming the photodiode; forming the floating diffusion area, separate from the photodiode; and/or forming the transfer gate, near the photodiode, to transfer optical charges accumulated in the photodiode.
摘要:
A semiconductor memory device includes a first conductive line on a semiconductor substrate, an interlayer insulating layer on the first conductive line, a second conductive line on the interlayer insulating layer, and a memory cell in an hole through the interlayer insulating layer wherein the first and second conductive lines cross, the memory cell including a discrete resistive memory material region disposed in the hole and electrically connected between the first and second conductive lines. The resistive memory material region may be substantially contained within the hole. In some embodiments, contact between the resistive memory material region and the interlayer insulating layer is substantially limited to sidewalls of the interlayer insulating layer in the hole.
