| 20110018656 | WAVEGUIDE ADAPTER ABLE TO GENERATE CIRCULARLY POLARIZED WAVE - Disclosed is a waveguide adapter able to generate a circularly polarized wave. The waveguide adapter to be coupled with a horn antenna realizes a polarized wave conversion function for converting a linearly polarized wave signal into a circularly polarized wave signal, or vice versa, and an adapter function for converting a waveguide signal into an external transmission line signal, resulting in a simplified configuration and small size of a communication system using a circularly polarized wave signal. The waveguide adaptor includes a probe to transmit a linearly polarized wave signal from an external transmission line to a waveguide transmission line, a polarized wave conversion line reflector located in the rear of the probe to convert a vertically polarized wave into a horizontally polarized wave, and a back-short member to forwardly transmit a rearward signal. The waveguide adapter is applicable to communication systems using circularly polarized wave signals. | 01-27-2011 |

| 20090134957 | Film bulk acoustic resonator package and method for manufacturing the same - A film bulky acoustic resonator (FBAR) package and a method for manufacturing the package are provided. A top surface of a FBAR on a substrate is entirely covered with a cap and a signal line connected to an external circuit unit is directly attached to a bonding pad of the FBAR through a substrate via-hole formed through the substrate. Since the signal line connected to the external circuit unit is directly attached to the bonding pad of the FBAR through the substrate via-hole formed through the substrate, a process for attaining a signal line connection space of the external circuit unit can be omitted. Therefore, an overall working process can be simplified and the manufacturing cost can be reduced, while improving the production yield. Furthermore, a size of the FBAR can be remarkably reduced. In addition, as described above, when the signal line connected to the external circuit unit is directly attached to the boding pad through a bottom of the substrate, a length of the signal line can be minimized and thus the deterioration of the FBAR, which may be caused during a wafer level packaging process, can be reduced. | 05-28-2009 |

| 20110017170 | 8-STROKE INTERNAL COMBUSTION ENGINE - The present invention relates to an 8-stroke internal combustion engine which generates power in a highly efficient manner by injecting water such that the combustion gas is re-circulated, retaken into a cylinder block and recompressed immediately after 4-strokes resulting from the burning of fuel such that 4-strokes resulting from the combustion of fuel and 4-strokes resulting from the evaporation and volume expansion of injected water are alternately repeated. The 8-stroke internal combustion engine of the present invention includes a cylinder block for generating rotating power by receiving up and down reciprocation of a piston through a connecting rod and consequently rotating a crank shaft, a cylinder head coupled onto the cylinder block and having one side connected with an intake manifold which opens/shuts via an intake valve and the other side connected with an exhaust manifold which opens/shuts via an exhaust valve, a first camshaft which is arranged on the cylinder head, rotates in tandem with the rotation of the crank shaft, and equipped with an intake cam for driving the intake valve, a second camshaft which is arranged on the cylinder head, rotates in tandem with the rotation of the crank shaft, and equipped with an exhaust cam for driving the exhaust valve; a water injection unit arranged on the cylinder head to inject water into the cylinder block; a third camshaft arranged on the cylinder head, rotates in tandem with the rotation of the first camshaft, and equipped with a water injection mechanism for operating the water injection unit, a combustion gas bypass pipe for interconnecting the intake manifold and the exhaust manifold, a combustion gas intake controller arranged on the intake manifold and connected to the combustion gas bypass pipe to selectively control mixtures of air, intake air, or re-intake of combustion gas, and a combustion gas exhaust controller arranged on the exhaust manifold and connected to the combustion gas bypass pipe to selectively control the exhaust or re-circulation of combustion gas. | 01-27-2011 |
| 20110061617 | INTAKE AND EXHAUST APPARATUS FOR FOUR-STROKE INTERNAL-COMBUSTION ENGINE - The present invention comprises a cylinder block wherein vertical reciprocation of a piston is transmitted to a connecting rod then rotates a crank shaft to generate torque. A cylinder head is joined to the top of the cylinder block, whereof one side is connected to a primary intake and exhaust manifold which is opened and shut by a primary intake and exhaust valve and the other side is connected to a secondary intake and exhaust manifold which is opened and shut by a secondary intake and exhaust valve. A primary cam shaft is placed on the upper side of the cylinder head and rotates to interlock with the rotation of the crank shaft and is connected with a primary intake and exhaust cam driving the primary intake and exhaust valve. A secondary cam shaft is placed on the upper side of the cylinder head and rotates to interlock with the rotation of the crank shaft, and is connected with a secondary intake and exhaust cam driving the secondary intake and exhaust valve. A tertiary cam shaft is placed on the upper side of the cylinder head and rotates to interlock with the rotation of the secondary cam shaft.
