▪ US Patent No. 8,722,257 (Korea Electrotechnology Research Institute)
발명의 명칭: Pressing-type cylindrical metal air battery
대표도면:
대표독립항:
1. A metal air battery, comprising:
an external case formed in a cylindrical shape, and having a cathode terminal at a first end thereof and an anode terminal hole at a second end thereof;
an internal case formed in a cylindrical shape, coaxially received in the external case, and having at a first end thereof an anode terminal, the internal case being moveable in a coaxial direction within the external case and having air inflow holes formed in a cylindrical wall portion of the internal case to permit inflow of air therethrough; and
elastic sealing means provided at a second end of the internal case, the elastic sealing means enabling the internal case to elastically move in the coaxial direction and thereby causing the anode terminal to elastically move into the anode terminal hole and allow the air to flow into the anode terminal hole and into the air inflow holes of the internal case as the anode terminal is elastically pressed when the battery is inserted into a battery compartment, the elastic sealing means further enabling sealing the anode terminal hole to block the air from flowing through the anode terminal hole and through the air inflow holes of the internal case as the anode terminal elastically restores its initial position when the battery is separated from the battery compartment.

발명의 명칭: Apparatus for controlling the operation of an LED, and method for controlling drive current thereof
대표도면:
대표독립항:
1. An apparatus for controlling the operation of LEDs using an AC power source, comprising:
a first LED array configured to have a first side connected to an output side of the AC power source;
a second LED array configured to have a first side connected to an input side of the AC power source;
a rectification unit configured to have an input side connected between the output side of the AC power source and the first side of the first LED array, between the input side of the AC power source and the first side of the second LED array, to a second side of the first LED array, and to a second side of the second LED array; and
an operation control unit configured to have an input side connected to an output side of the rectification unit and an output side connected to the input side of the rectification unit and to control a plurality of input currents output from the rectification unit and then received through the input side of the operation control unit so that the plurality of input currents is selectively output to the second side of the first LED array and the second side of the second LED array.

발명의 명칭: Rope-conveyer structure for supporting plates of wind or water power generator
대표도면:
대표독립항:
1. A rope-conveyor structure for supporting plates of a wind or water power generator in which the plates are coupled to a rope at positions spaced apart from each other so that a flowing force of a fluid applying to the plates rotates the rope, the rope-conveyor structure comprising:
a plurality of couplings connected to the rope between the respective plates; and
a plurality of connection wires having first ends thereof connected to the respective couplings and second ends thereof connected to the respective plates, wherein a fastener is provided at the first end of each of the connection wires, the fastener being detachably coupled to the corresponding coupling so that the connection wire is able to be selectively coupled to one of the couplings that is disposed either ahead of or behind the corresponding plate.
