Abstract:
There are disclosed a method of manufacturing fine metal powder and fine metal powder manufactured by using the same. The method of manufacturing fine metal powder includes forming a pattern having a predetermined size and shape on a base substrate, forming a metal film on the pattern, and separating the metal film from the pattern to obtain individual metal particles having a predetermined size and shape. The fine metal powder manufactured by the method has a uniform shape and a uniform particle size distribution. The fine metal powder is in the form of flakes, having a large ratio of particle diameter to thickness.

Abstract:
In an electro-motion type automatic clip-ejecting apparatus, when paper to be bound is inserted into the apparatus after a large number of clips are charged in the clip magazine, each clip is simultaneously ejected from the clip magazine so that a binding operation is performed so that it is possible to conveniently use the clip ejecting apparatus by only one hand of the user. The apparatus includes a wheel movement member and a clip ejecting member. The wheel movement member includes a pole, a spring for providing elastic force, and a pole movement bar for performing a linear movement so that the pole movement bar is interlocked with the pushing rack gear. The pole is interlocked with the pole movement bar according to linear movement of the pole movement bar. The clip ejecting member includes a spar gear, a fixed gear, and a pushing rack gear.
Abstract:
There is provided an electronic paper display device and a method of manufacturing the same. The electronic paper display device includes first and second electrodes opposing each other, a plurality of rotary bodies disposed between the first and second electrodes and having electrical and optical anisotropy, elastomer matrix blocks each surrounding at least one of the plurality of rotary bodies and spaced apart from each other, and an optical adhesive formed between the elastomer matrix blocks. The electronic paper display device achieves a high contrast ratio and a relative low driving voltage. Also, the use of the optical adhesive facilitates the adhesion of the first and second electrodes, and blocks the vaporization of dielectric liquid filing a cavity, thereby ensuring high reliability.
Abstract:
A data transmitting/receiving method and apparatus for allocating optimal sub-bands and transmission power levels and transmitting data in a ultra wide band (UWB) communication system. The method includes receiving data through sub-bands of each band group; determining performance ranks of the sub-bands based on error rates and differences of transmitting and receiving power levels of the received data; selecting a predetermined number of sub-bands according to the performance ranks of the sub-bands; generating power level adjustment information based on measured power levels of data of the selected sub-bands; and receiving data according to the selected sub-bands and the power levels.
Abstract:
An appliance including a cabinet having a first PCB located therein, a door connected to the cabinet, the door being moveable between an open position and a closed position to open and close the cabinet, and a second PCB located in the door. In addition, at least one first connector is connected to the first PCB. At least one second connector is connected to the second PCB and is electronically connectable to the first connector. In particular, the second connector is electrically connected to the first connector when the door is in a substantially closed position.
Abstract:
A method, apparatus, and medium for erasing information recorded on a rewritable recording medium. The method includes: searching for test result information on a recording power recorded on a recording management area disposed on the recording medium; if corresponding test result information is found, reading in the test result information; and by using a recording power determined according to the read test result, recording a unique pattern on at least part of a user data area of the recording medium where predetermined information is recorded. According to the method, the writing characteristic can be greatly improved.
Abstract:
In a method of classifying defects, actual information with respect to actual defects by each of processes on an object on which the processes are sequentially carried out is obtained. The actual information is accumulated in sequence of the processes to obtain composite information by each of the processes with respect to entire defects that are generated in preceding processes. Added information with respect to defects, which are generated only in each of the processes, among the actual defects is obtained by each of the processes based on the actual information and the composite information. The added information contains information with respect to the defects generated only in each of the processes so that the detected defects may be accurately classified as defects generated in any one among the processes based on the added information.
Abstract:
A cleaner comprises a cleaning fluid container installed at a cleaner body, for providing a space in which a cleaning fluid is stored; a cleaning fluid dispensing unit for dispensing a cleaning fluid in the cleaning fluid container to a cleaning region; a brush rotatably installed at a bottom of the cleaner body, for brushing a cleaning region by being rotated; a recovery unit for recovering a soiled fluid including a filth from the cleaning region; a recovery fluid container installed at the cleaner body, for storing the recovered soiled fluid; and a drying unit for heating air and dispensing the heated air to the cleaning region. Accordingly, the moisture remaining at a cleaning region is quickly removed, and so cleaning efficiency can be improved.
