An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.

A dispersant for a more concentrated carbon nanotube solution, and a composition including the same are provided. The dispersant may have a hydrophobic chain structure with head groups capable of surrounding carbon nanotube particles. The dispersant may adsorbed onto the carbon nanotube particles. The composition may include the dispersant, an aqueous liquid medium and a carbon nanotube. The composition may further include an additive. It may be possible to produce a more concentrated carbon nanotube solution exhibiting an increase in dispersion of the carbon nanotube particles and/or more stability.

The present invention is directed to a liquid crystal display device and a method for driving the same for a fast transition into a bend state at initial operation such as immediately after power is inputted in a liquid display device with an OCB mode. According to one feature of the present invention, as power is inputted, a timing controller controls to output at least one of a gate voltage for a scan signal, a data voltage for a picture signal, and a driving voltage for a backlight by outputting a first switching signal to a switching unit, and controls to output one of an external bias voltage and a common electrode voltage by outputting a second switching signal to the switching unit so that fast transition into bend state of liquid crystal arranged in a LCD panel is accomplished. As a result, by applying a voltage of less level than that of the typical common electrode voltage to the LCD panel, as DC voltage of at least 10 volt to 20 volt is applicable to a common electrode, time for transition into bend state can be reduced at initial operation of the liquid crystal display device using the LCD panel with OCB mode.

A dust collection unit for a vacuum cleaner includes a dust collection container for collecting foreign objects contained in air introduced therein, covers defining a top and bottom of the dust collection container, and a filter-cleaning unit having a plurality of brushes rotating around the porous filter unit to remove the foreign objects clogging the outer surface of the porous filter unit.
摘要:
An apparatus for connecting a multi-conductor cable of a first device to a pin grid array connector of a second device, wherein said apparatus comprises a first printed circuit board (PCB) for terminating the conductors of the cable, which are connected to a first PCB surface mounted connector mounted on the first PCB. The first PCB surface mounted connector is mated with a second PCB surface mounted connector mounted on a second PCB, on which a PCB surface mounted socket grid array is also mounted for mating to the pin grid array connector of the second device. This apparatus allows the same (i.e., standardized) multi-conductor cable with the same first PCB and the same first PCB surface mounted connector to be used regardless of what style connector is used by the second device.
摘要:
A pulse of heat or cold is applied and conducted transversely through a ball grid array device and a printed circuit board via a selected one of the solder joints between them. Heat diffused through the other solder joints is neutralized by a thermal bias shield. The shield is then removed and a thermographic image of the printed circuit board is taken. The process is repeated for each solder joint, and the images are compared to identify defective solder joints.
摘要:
The present invention relates to a flat type heat transferring device, and manufacturing method of the same, which is comprises of a capillary wick that is provided inside a case and formed by weaving a wire in the horizontal direction and the vertical direction so as to absorb a liquid coolant, and a linear member that is formed to have a different wire diameter from the wire of the capillary wick and woven in the capillary wick to form a space where a vapor coolant flows. Accordingly, the mechanically stabilized support rigidity can be secured and an ultra thin configuration can be implemented with a light-weight, in particular, the problem of degrading the capillary force is resolved, and it has the effect that the cooling efficiency can be improved with smooth flowing of a coolant.

The present invention relates to a surface expression vector expressing a parvovirus antigen on the surface of microorganisms, the vector containing not only a gene encoding the capsid antigen protein of parvovirus causing canine parvovirus (CPV) infection and feline panleukopenia (FLP) but also at least one of pgsB, pgsC and pgsA genes encoding a poly-gamma-glutamate synthetase complex. Also, the present invention relates to microorganisms transformed with the surface expression vector, and parvovirus vaccines containing the transformed microorganisms. According to the present invention, the use of the recombinant bacterial strains expressing the parvovirus antigen on their surface allows the economical production of vaccines for the treatment and prevention of canine parvovirus infection and feline panleukopenia.
