Abstract:
A streamer discharge type lightening rod is disclosed, which is capable of generating lots of ions so that a certain object can be effectively protected from lightening in such a manner that an induction current is formed using ions in the air as thundercloud is formed, and ions having polarities corresponding to the ions in the air are greatly generated at a surface of the lightening rod, and a streamer by a corona discharge is increased at a surface of the thundercloud for thereby inducing lightening from a thundercloud as fast as lightening is naturally generated.
Abstract:
A method for controlling a portable personal device having facilities for storing and playing digital contents by a computer and an operation method of the portable personal device thereby are provided. The operation method of the portable personal device by control from a computer through a serial or parallel cable has the steps of (a) receiving a format request command from the computer for formatting an internal memory installed in the portable personal device or an external memory in an external memory card; (b) sending from the portable personal device a signal indicating that the portable personal device is ready to format to the computer; (c) receiving an execution command from the computer for executing the format request command received in the step (a); and (d) formatting the corresponding memory and then sending the result to the computer.
Abstract:
The present invention relates to cinnamic acid dimers, their preparation and the use thereof for treating neurodegenerative disease, which have excellent effect on enhancing the learning and memory-retention ability in vivo and have fewer side-effects by showing no hormone properties, even when administered for a long period of time, and thus which can be used for neurodegenerative disease including dementia.
Abstract:
It is very common phenomenon that babies drop their toys or spoons down on the floor or ground while they playing with toys or eating food with spoons as sitting on the baby carriage or babies' chair.The present invention is a protection net on which a purse or bib is attached; which is designed to catch a toy or spoon when one-to-three-year-old baby drops his or her toy or spoors, down while he or she plays with a toy or eating food with a spoon as sitting on the babies' chair or babies' carriage.
Abstract:
Disclosed are compositions and methods for producing a cathode for a secondary battery, where lithium manganese fluorophosphate such as Li2MnPO4F can be used as an electrode material. Li2MnPO4F is prepared by chemical intercalation of lithium, and can be used as an electrode material, and a non-lithium containing material can then be used as an anode material for manufacturing of a full cell. Furthermore, it is possible to provide a carbon coating for a cathode material for a lithium battery, which has improved electrical conductivity.
Abstract:
The present invention relates to a metalizing film including a polyester-based film layer having a heat-shrinking property, and a use of the metalizing film used as a film label capable of replacing a paper label attached to a glass bottle.
Abstract:
There is provided a base assembly for a motor, the base assembly including: a base supporting rotation of a rotating member of the motor; and a pulling plate provided to the base to thereby prevent excessive floating of the rotating member, wherein the pulling plate includes a body part not in contact with the base and an extension part extended from the body part to thereby contact the base.
Abstract:
A network identifier position determination system and method. The network identifier position determination system includes a network identification module. When a terminal is connected to a network system through a wired/wireless network, the network identification module checks a network identifier that the terminal uses in order to be connected to the network system. A positioning module checks position information of a user corresponding to the terminal that is connected to the network system using the network identifier. A control module which maps a determination position that is determined based on the position information checked by the positioning module to a position of the network identifier.
Abstract:
A solar cell module includes a substrate, a lower electrode layer, a semiconductor layer and an upper electrode layer for an embodiment. The lower electrode layer may include a plurality of area-separating grooves separating the substrate into an active area and a peripheral area surrounding the active area, and a plurality of first cell-separating grooves formed in the active area. The semiconductor layer is formed on the lower electrode layer. The semiconductor layer includes a plurality of second cell-separating grooves that are spaced apart from the first cell-separating grooves. The upper electrode layer is formed on the semiconductor layer. The upper electrode layer includes a plurality of third cell-separating grooves that are spaced apart from the second separating grooves.
