| 20120083989 | COMBUSTION DETECTING METHOD OF ENGINE - A combustion phase detection method is able to reduce exhaust gas and to improve combustion stability, to compensate injection and ignition delay time between combustion chambers and between cycles, and to detect a combustion phase in real time such that a heat generation rate and a heat release can be effectively calculated at an early state of the combustion by using a combustion pressure and a motoring pressure difference of an engine not affected by an offset value of the cylinder pressure. The combustion phase detection method of an engine may include detecting a combustion phase according to fuel injection timing by using a specific point of DHdP that is calculated by the following heat release equation: | 04-05-2012 |
| 20120083992 | COMBUSTION DETECTING METHOD OF ENGINE - A combustion phase detection method of an engine has the advantages of being able to reduce exhaust gas and to improve combustion stability, to compensate injection and ignition delay time between combustion chambers and between cycles, and to detect a combustion phase in real time such that a heat generation rate and heat release can be effectively calculated in an early state of combustion with a simple calculation method to control combustion of an engine, by using a combustion pressure and a motoring pressure difference of an engine not affected by an offset value of the cylinder pressure. For this, a combustion phase detection method may include detecting a combustion phase by using a specific point of DRdV as follows: | 04-05-2012 |

| 20100223420 | Memory system and data management method of flash translation layer thereof - A data management method includes determining the size of input data, storing the input data in a log block if the size of the input data is determined to be a write unit, and storing the input data in a partial block if the size of the input data is determined to be smaller than the write unit. The log block is a temporary block storing data of same addresses and the partial block is a temporary block storing data regardless of their addresses. The memory system includes a nonvolatile memory and a memory controller configured to control the nonvolatile memory. The memory controller is configured to temporarily store input data smaller than a write unit in a selected memory block even when the input data have different addresses. | 09-02-2010 |

| 20110239236 | OPTICAL DISC DRIVE - An optical disc drive is disclosed. The optical disc drive comprises an optical pickup base including an optical pickup movable in the radius direction of an optical disc; and a main base holding the optical pickup base, wherein the main base comprises a guide rib protruding from the main base and guiding the air flow generated by the rotation of the optical disc to the optical pickup. Further, the optical pickup comprises an air spoiler for preventing contamination of an objective lens included in the optical pickup. The optical disc drive is able to control the temperature of an optical pickup unit by guiding the air flow generated by the rotation of an optical disc to the optical pickup. Moreover, the optical disc drive can reduce contamination of the objective lens of the optical pickup due to the air flow generated by the rotation of the optical disc. | 09-29-2011 |
| 20110239237 | OPTICAL DISC DRIVE - An optical disc drive is disclosed. The optical disc drive comprises a housing including an upper housing and a lower housing; and a herringbone pattern that is protruded toward the inner space of the housing on the inner surface of the upper housing and causes an air flow generated by the rotation of an optical disc to be switched to the direction of the optical disc. The herringbone pattern comprises at least one inflection point, and makes an acute angle at the inflection point relative to the direction of the air flow formed along the inner surface of the upper housing. Accordingly, the optical disc can be stably chucked and rotated by switching the air flow generated by the rotation of the optical disc to the direction of the optical disc. | 09-29-2011 |
