20080278726 | Device Having an Optical Part for Analyzing Micro Particles - Disclosed is a micro particle analyzing device illuminating light to fluid including micro particles, reading the lights emitted from the micro particles at a signal processing reading section and thus analyzing the micro particles. The device comprises a light source section emitting light which will be illuminated to the fluid; a lens regulating an amount and a focal distance of the light emitted from the light source; and a concave mirror condensing light emitted from the micro particle to reflect it to the reading section wherein the concave mirror is formed with a hole so that the light of the light source section having passed through the lens can pass through the concave mirror. When analyzing the micro particles using the analyzing device according to the invention, the amounts of lights emitted from the micro particles according to up-and-down positions of the micro particles are not different. | 11-13-2008 |
20080304720 | Channel Apparatus for Focusing a Fluid Flow - Disclosed is a focusing channel device which focuses fluid containing micro particles so that the micro particles flow in a line. The channel device comprises a nozzle formed by left and right walls each of which comprises an inclination surface. The cross sectional area in vertical direction decreases from the entrance of the nozzle toward the exit of the nozzle. The shape of cross sectional view in horizontal direction is asymmetric for the central line in the length direction. Using the focus channel device of the invention, the micro particles in the fluid are not combined with each other and passed through the channel one by one. Thus, blockage of the channel or combination and movement of two particles together does not occur. | 12-11-2008 |
20130058085 | CONDENSING LENS AND LIGHTING DEVICE EQUIPPED WITH SAID CONDENSING LENS - Provided is a condensing lens condensing a light from a light source, and a lighting device equipped with the condensing lens. The condensing lens may enable a light to be selectively incident upon a plurality of first incident portions based on an emission angle, may totally-reflect, using a second incident portion, the light refracted by the plurality of first incident portions, and may refract the totally-reflected light using a third incident portion. | 03-07-2013 |

20110196573 | METHOD OF CONTROLLING INVERTER-INTEGRATED ELECTRIC COMPRESSOR FOR VEHICULAR AIR CONDITIONING SYSTEM - Disclosed is a method of controlling an inverter-integrated electric compressor for a vehicular air conditioning system, which prevents an over-current from being generated due to a load of an inverter for driving the electric compressor and reduces an RPM even without stopping the vehicular air conditioning system, preventing damage to the air conditioning system due to an over-current. The method of controlling an inverter-integrated electric compressor for a vehicular air conditioning system includes the steps of: (1) calculating a target RPM of a motor for driving the inverter-integrated electric compressor in a vehicular air conditioning system; (2) checking whether a current applied to the motor driven according to the target RPM exceeds a threshold value preset in the inverter; and (3) decreasing, if the current applied to the motor exceeds the threshold vale, the target RPM in the inverter to perform a feedback control of reducing the current, and rotating, if the current applied to the motor does not exceed the threshold value, the motor according to the target RPM. | 08-11-2011 |
20120100012 | METHOD FOR CONTROLLING ELECTRIC COMPRESSOR - Disclosed is a method of controlling an electric compressor. The method includes: (I) starting the electric compressor by applying an electric power to an air conditioner; (II) determining, by an inverter, whether the electric compressor is started normally; and normally driving the electric compressor when the electric compressor starts normally in the step (II) and determining again whether the electric compressor starts normally by restarting the electric compressor. Therefore, abnormal operation such as malfunction, short, and overheating of the electric compressor is detected in the early starting stage to determine restarting and failure of starting the electric compressor so that reliability of the electric compressor may be enhanced. | 04-26-2012 |
