    摘要： A lead frame unloading apparatus includes a pair of opposing plate members, one of which has a long horizontal slit. The opposing plate members define a central space where one or more sliding blocks are located, each of the sliding blocks having a vertical through hole at its center. A picker penetrates through the vertical hole within each respective sliding block, each picker is immobilized when it contacts a lead frame for pickup thereby allowing the sliding block to move vertically up and down on the immobilized pickers, each of the pickers having a vacuum suction device at one end thereof, and a vacuum screw at the other end thereof. The vacuum screw has a hollow projection connected to a vacuum supplier. A spring is disposed beneath respective of the one or more sliding blocks, with the spring being fitted to an outside of the vacuum suction device. Spring stoppers support the springs and fastening devices fasten the one or more sliding blocks to the opposing plate members. The one or more sliding blocks are horizontally movable within the central space between the two opposing plate members by loosening the fastening devices.

    摘要： Disclosed are a patterning method of a metal oxide thin film using nanoimprinting, and a manufacturing method of a light emitting diode (LED). The method for forming a metal oxide thin film pattern using nanoimprinting includes: coating a photosensitive metal-organic material precursor solution on a substrate; preparing a mold patterned to have a protrusion and depression structure; pressurizing the photosensitive metal-organic material precursor coating layer with the patterned mold; forming a cured metal oxide thin film pattern by heating the pressurized photosensitive metal-organic material precursor coating layer or by irradiating ultraviolet rays to the pressurized photosensitive metal-organic material precursor coating layer while being heated; and removing the patterned mold from the metal oxide thin film pattern, and selectively further includes annealing the metal oxide thin film pattern. Within this, there is provided a method for forming a metal dioxe thin film pattern using nano imprinting, which makes it possible to simplify the process for forming the pattern since the process of separately applying the ultraviolet resin to be used as the resist can be omitted, and forms a micro/nano composite pattern through a single imprint process.

    摘要： A claw-pole PM stepping motor includes a module that is formed in such a manner that a first driving unit and a second driving unit are symmetrically arranged with respect to a first claw-pole and a second claw-pole each oppositely disposed at a main yoke member internally disposed to substantially divide an inside of a housing, an inner portion of which is rotatably inserted and supported by a rotary shaft, and the first driving unit and the second driving unit have magnet rotors coaxially arranged to generate electromagnetic force; sub-yoke members; and coil bobbins. The claw-pole PM stepping motor is exempted from a structure where coil bobbins are concentrically arranged at a periphery of magnet rotors, and instead the coil bobbins are coaxially arranged and shifted from each other from the corresponding magnet rotors, such that a miniaturized motor with a reduced outer diameter can be embodied.
