The aluminum chelate complex useful as an organic EL material is represented by L | 05-21-2009 |
| 20110094433 | UNDERWATER POSTURE STABILIZATION SYSTEM AND DIVING APPARATUS EQUIPPED WITH THE SAME - Provided is an underwater posture stabilization system which, by being attached to various underwater equipment such as undersea equipment and underwater vehicles having different shapes and positions of the center of gravity according to their purpose and the like, allows simply and reliably setting their posture in water (basic posture), is excellent in versatility, is not only excellent in posture stability since, when the posture inclines under the effect and the like of tidal currents and pulsating currents, a moment to restore the posture to its original posture naturally acts, but is also capable of easily changing the posture as needed, and also is capable of stably controlling the posture even in the presence of complicated tidal currents and pulsating currents, and is excellent in reliability, stability, and certainty of posture control. The underwater posture stabilization system includes a frame to be attached to an apparatus body of the underwater equipment, a pair of sliding portions arranged so as to be freely movable back and forth on both side portions of the frame, a support member freely movable up and down which is fixed at a lower end thereof to each sliding portion, and arranged upward or obliquely upward, and a floating body arranged at a tip of each support member. | 04-28-2011 |

| 20080285915 | Optical transmission system - An optical transmission system ( | 11-20-2008 |
| 20090190882 | Optical device, optical communication apparatus, and method of controlling optical device - An optical device includes an I/O port group and a movable mirror reflecting light input through an input port of the I/O group, aligning the light reflected with an output port of the I/O port group, and changing the angle of the light reflected according to a driving voltage supplied thereto. The optical device further includes a control unit that adjusts the driving voltage within a range lower than the voltage at which the degree of alignment of the light with respect to the output port is maximized and controls attenuation of the light reflected by the moveable mirror. | 07-30-2009 |
| 20090244674 | MIRROR DRIVING CIRCUIT AND OPTICAL SWITCH - A mirror driving circuit applies a voltage to drive a mirror and switches an optical path of light output from a channel of an input port to a channel of an output port. The mirror driving circuit includes an offset-voltage applying unit that applies an offset voltage to the mirror, an applied-voltage determining unit that determines an applied voltage to be applied to the mirror based on a relation between the channel of the input port and the channel of the output port forming a path of the light, and a voltage applying unit that applies to the mirror a remaining voltage obtained by subtracting the offset voltage from the applied voltage. | 10-01-2009 |
| 20090244675 | ELECTRODE AND MIRROR DRIVING APPARATUS - An electrode includes a fixed electrode and a movable electrode. The electrode drives a mirror disposed on the side of the movable electrode by generating electrostatic force between the fixed electrode and the movable electrode when voltage is applied. The fixed electrode and the movable electrode are formed so that a distance between the fixed electrode and the movable electrode increases as an overlapping area between the fixed electrode and the movable electrode increases. | 10-01-2009 |
| 20100239269 | PHASE SYNCHRONIZATION APPARATUS AND DIGITAL COHERENT LIGHT RECEIVER - A phase synchronization method uses a removal path for removing an error component contained in an input signal and a delay addition path for adding a delay corresponding to a processing time period taken to remove the error component in the removal path. The removal path includes an averaging section. The averaging section includes a shift register and an obtaining unit. The shift register stores as many data as the maximum number of data to be averaged and successively receives processing data from which the error component has been extracted in the removal path. The obtaining unit obtains, among the successive processing data input to the shift register, as many processing data as the number of data to be averaged from a position near the center toward both ends in the shift register. | 09-23-2010 |
