Abstract: An apparatus is disclosed which can shape fruits and root and tuberous vegetables. The shaping apparatus is operated in such a manner that: when root and tuberous vegetable or fruit is placed in a cutting blade case and rotated, the object is spirally tracked and the spirally tracked object is removed from the lower side of the cutting blade case, so that the spirally tracked object is picked up by an additional stick and then ornamented into various forms. The shaping apparatus allows fruits and root and tuberous vegetables to be easily treated in a variety of ways, as per the second process, thereby enhancing the product value of processed foodstuffs produced from the first process.

Abstract: An aerosol spray apparatus and a method of forming a film using the aerosol spray apparatus are disclosed. The aerosol spray apparatus in accordance with an embodiment of the present invention includes: a carrier gas injection unit, which forms carrier gas by vaporizing liquefied gas and increases the pressure of the carrier gas; an aerosol forming unit, which forms an aerosol by mixing the carrier gas with powder; and a film forming unit, which sprays the aerosol in a normal pressure environment such that the film is formed on the surface of the board. The apparatus can perform a coating process with no restriction of the type and size of powder, simplify the process because the film can be formed in a normal temperature and pressure environment, and control a wide range of film thickness in a short time.

Abstract: A cylindrical battery including a wound electrode assembly and a center pin disposed in a center space of the electrode assembly, the center pin having a gap along its length, the gap defined by opposing edges of the center pin, wherein at least one of the opposing edges is sloped.

Abstract: This invention relates to a method of conducting search of moving picture data stream and repeating playback of a data stream section based on the caption information, which is displayed with moving pictures, and a reproduction apparatus using such method. The present method creates and stores link information between caption data and position of moving picture stream which is reproduced concurrently with the caption data; displays a part of the caption data during playback; searches for a moving picture data section, which is concurrently presented with a particular caption chosen from the displayed caption data by a viewer, based on the created link information; and repeats playback of the found moving picture data section. This method is very useful to language practice because it can repeat to play a video section containing captions that a viewer wants to listen repeatedly.

Abstract: A system for preparing nanoparticles using non-thermal pulsed plasma is provided. The system comprises a reaction chamber having two divided regions, i.e. a first region where nanoparticles are to be formed and a second region where the nanoparticles are to be received, to prevent the formation of a thin film of nanoparticles in the second region. The use of the system enables the preparation of nanoparticles with improved uniformity and high collection efficiency. In addition, collection and deposition of nanoparticles can be simultaneously performed in the second region. Therefore, the system can find applications in various fields, including devices, secondary cells and sensors. Further provided is a method for preparing nanoparticles using the system.

Abstract: A drum-type washing machine is equipped with a drying device, which increases condensing efficiency by increasing the contact of air flowing along a condensing duct with cooling water, and prevents water formed in a condensing duct from flowing into a fixed drum. The washing machine is equipped with a drying device, which includes a discharging duct to connect an outlet of a blowing fan with an air inlet of a fixed drum and provided with a heater therein, and a condensing duct to connect an air inlet of the fixed drum with an inlet of the blowing fan and provided with a condensing unit to remove moisture. The condensing unit includes a cooling water dispersion member disposed in the lower portion of the inside of the condensing duct and a cooling water supply pipe configured to supply cooling water to the cooling water dispersion member.

Abstract: A can for a lithium secondary battery and a lithium secondary battery using the same, where guide slots are formed in a bottom wall and a sidewall of the can of the lithium secondary battery so that the can is symmetrically bent about a longitudinal axis thereof when the lithium secondary battery is compressed in a direction orthogonal to the longitudinal axis, thus preventing a short circuit from occurring between electrode plates of the of the electrode assembly located within the can resulting in improved safety of the lithium secondary battery. Alternatively, embossing portions are formed in a bottom wall of the can for the lithium secondary battery while protruding toward an inner portion of the can, so that the bottom wall of the can is outwardly bent when the lithium secondary battery is subject to compression in a direction orthogonal to the longitudinal axis, resulting in improved safety of the lithium secondary battery.

Abstract: The present invention relates to an individual answering method for an automatic answering telephone set which can selectively ring the telephone when a call is received by distinguishing absent users from users who are at home. A plurality of individual answering mode setting buttons are provided and enable each user to individually set an automatic answering function. Also, the user can push an automatic answering mode setting button or individual answering mode setting button during a conversation to allow the caller to leave a voice message for another user.

Abstract: A robot cleaner, a system thereof, and a method for controlling the same. The robot cleaner system includes a robot cleaner that performs a cleaning operation while communicating wirelessly with an external device. The robot cleaner has a plurality of proximity switches arranged in a row on a lower portion of the cleaner body. A guiding plate is disposed in the floor of the work area, the guiding plate having metal lines formed in a predetermined pattern, the metal lines being detectible by the proximity switches. Since the recognition of the location and the determination of traveling trajectory of the cleaner within a work area becomes easier, performance of the robot cleaner is enhanced, while a burden of having to process algorithms is lessened.
