Abstract:
The present invention relates to an intake manifold for a vehicle and comprises tanks for stabilizing intaken air introduced from a throttle body; a plurality of zip tubes diverged from the tanks; a plurality of runners connected to the zip tubes and communicated with respective cylinders; and a adjustment apparatus provided at one side of the zip tubes and the runners for varying the diameter of the zip tube and the diameter of the runner according to an engine operation range. Due to the above structure, the diameter of the zip tube and the diameter of the runner can be varied continuously within the overall operating range of an engine by the adjustment apparatus. Hence, the performance of the engine can be enhanced.
Abstract:
An apparatus and a method for transmitting and receiving moving picture data, which can stream the moving picture through the near narrowband communication network in real time by using a portable terminal having a near field communication module like a Bluetooth module. The apparatus transmits some of audio visual data stored in the form of a file which is prescribed by Moving Picture Experts Group to the portable terminal connected to the near field communication network to allow the portable terminal to replay the audio visual data. Then, the apparatus divides the residual data into files with a desired size and transmits the files to the portable terminal, so the portable terminal can simultaneously receive and replay the moving picture.
Abstract:
The present disclosure relates to a light driving apparatus which may stably drive an LED light at a normal operation by feeding back the output voltage of the LED light and stably drive the LED light at an abnormal operation by feeding back the voltage supplied to the LED light, and the light driving apparatus includes: a rectifier circuit; a transformer circuit; a power factor correction circuit; a smoothing circuit; a constant-current driving circuit; a dimming control circuit; a photo-coupler; a sample and hold circuit; a first photo-coupler driving circuit for feeding back the voltage output from the sample and hold circuit and applying the feedback voltage as a driving voltage of the photo-coupler; and a second photo-coupler driving circuit for feeding back the voltage output from the smoothing circuit and supplied to the LED module and supplying the feedback voltage as a driving voltage of the photo-coupler.
Abstract:
Disclosed is an apparatus for electrifying spacers and an apparatus for scattering spacers using the same. For the purpose of maintaining a cell gap of a LCD, the spacer is electrified to have a first electrified voltage by a first electrifying pipe having a first curvature, and the spacer is electrified by a second electrifying pipe having a second curvature to have a second electrified voltage level high enough to prevent the spacers from being lumped. Thus, the spacer is not lumped by increasing an electrified voltage thereof, thereby preventing a quality of an image from being deteriorated, the spacer from being lost.
