Abstract: Disclosed herein is a method of printing a nanostructure including: preparing a template substrate on which a pattern is formed; forming a replica pattern having an inverse phase of the pattern by coating a polymer thin film on an upper portion of the template substrate, adhering a thermal release tape to an upper portion of the polymer thin film, and separating the polymer thin film from the template substrate; forming a nanostructure by depositing a functional material on the replica pattern; and printing the nanostructure deposited on the replica pattern to a substrate by positioning the nanostructure on the substrate, applying heat and pressure to the nanostructure, and weakening an adhesive force between the thermal release tape and the replica pattern by the heat.

Abstract: A wafer manufacturing method, an epitaxial wafer manufacturing method, and a wafer and epitaxial wafer manufactured thereby, are provided. The wafer manufacturing method enables the manufacture of a wafer with a low density of micropipe defects and minimum numbers of particles and scratches. The epitaxial wafer manufacturing method enables the manufacture of an epitaxial wafer that has low densities of defects such as downfall, triangular, and carrot defects, exhibits excellent device characteristics, and improves the yield of devices.

Abstract: A camera module is provided. The camera module includes a lens module including one or more lenses; an image sensor configured to convert light passing through the lens module into an electrical signal; and a filter configured to perform a polarization function, wherein the filter is configured to be movable in a space formed between the lens module and the image sensor.

Abstract: The present invention discloses a vacuum cleaner including a main body (1) of the vacuum cleaner, a wheel (2) rotatably mounted at the body, a driving unit for driving the wheel (2), a sensor (71) positioned at the main body, for sensing an inclined direction of the main body (1), and a control unit for controlling the driving unit according to the inclined direction of the main body (1) sensed by the sensor (71). In this configuration, the posture of the main body (1) of the vacuum cleaner can be controlled according to the inverted pendulum control theory. Therefore, the main body (1) of the vacuum cleaner can maintain the posture thereof not to fall down.

Abstract: A vacuum cleaner is provided that includes a vacuum cleaner main body having a suction pump, a suction nozzle portion that sucks impurities by a suction force supplied by the suction pump, a suction passage that connects the suction nozzle portion to the suction pump, an agitator installed at the suction passage, and a driving device that makes the agitator perform a linear translation. As the agitator is formed narrow and long, a bottom surface of the suction nozzle portion may maintain a small suction area. Therefore the vacuum cleaner attains a high surface pressure which is an advantage of an ordinary type suction nozzle portion, and a high drag coefficient of impurities which is an advantage of a brush type suction nozzle portion.

Abstract: The present invention discloses a vacuum cleaner which can improve the cleaning performance by filtering off impurities from the sucked air twice according to a cyclone method, and allow the user to easily discharge the collected impurities. The vacuum cleaner includes a primary cyclone unit (100), a secondary cyclone unit (120), and a passage partition unit (131) formed between the primary cyclone unit and the secondary cyclone unit. The sucked air is primarily filtered in the primary cyclone unit (110), and secondarily filtered in the secondary cyclone unit (120), thereby improving the cleaning performance. In addition, a dust container (140) is detachably coupled to the primary cyclone unit (110) or the secondary cyclone unit (120). Therefore, the user can easily remove the impurities collected in the dust container (140) by separating the dust container (140) from the primary and secondary cyclone units.

Abstract: In a top-loading type washing machine, a detergent input device is installed at a control panel. Accordingly, a process for opening a lid and putting a user's hand into a cabinet for detergent input is omitted. Furthermore, can be solved a problem occurring when the user inputs a precise amount of detergent to the detergent input device inside the dark cabinet. As a result, the entire process for detergent input is simplified. Furthermore, since the detergent input device is installed at the control panel not inside a top cover, the entire appearance is not degraded even when the top cover is formed of steel.

Abstract: A laundry machine includes: a casing; a door installed on an upper surface of the casing; a tub installed within the casing; and a buffering unit for buffering an impact when the door is closed. A collision noise or vibration of the door or the casing can be reduced and damage of the washing can be prevented. Also, a hinge assembly for connecting the door to a top cover is provided to stably support the door made of a heavy material such as tempered glass and minimizes an impact or noise when the door is closed.
