| 20100079221 | RESONATOR AND FILTER - The present invention provides a resonator and a filter that reduce the resonator radiation loss so as to achieve a high Q value that is inherent to a low-loss material while maintaining high power handling capability. In this manner, both high power handling capability and a high Q value can be achieved at the same time. The resonator is a microstripline structure and includes a line structure formed with resonance lines in which current standing waves are generated in a resonant state in a line, and currents in each two adjacent lines flow in the opposite directions from each other, and a connection line that connects the resonance lines at the portions having in-phase voltages among the nodes of the current standing waves of the resonance lines in the resonant state. The filter includes resonators of the same type as the above resonator. | 04-01-2010 |

| 20080259242 | POLARIZED LIGHT EMITTING DEVICE - A polarized light emitting device has a planar emitting device, a phase-shift device, a polarizing reflecting device, and a reflecting device. The planar emitting device emits light from a front and back surfaces of the planar emitting device. The phase-shift device transmits the light emitted from said planar emitting device, and changes the polarization direction of the light. The polarizing reflecting device transmits or reflects the light according to the polarization of the light emitted from the front surface or transmitted by said phase-shift device. The reflecting device reflects the light emitted from the back surface or transmitted by said phase-shift device. | 10-23-2008 |
