| 20090196615 | DISPERSION MAPPING OF TRANSMITTED CHANNELS IN A WDM SYSTEM - Chromatic dispersion is determined based on the arrival times of different frames of data in a wavelength division multiplexed (WDM) system having an optical communication link.

The relative time delay is the sum of the transmission time difference and the propagation time difference (the time difference attributable to chromatic dispersion) between the two frames. Thus, by subtracting the transmission time difference from the relative time delay, the propagation time difference can be obtained.

| 20090196659 | Image Forming Apparatus and Developing Apparatus - A casing of a developing apparatus defines a developing chamber and a developer accommodating chamber, that accommodates developer, therein. The developing chamber and the developer accommodating chamber are arranged side by side. The casing is formed with a replenishing port for supplying new developer from a developer replenishing unit into the developing chamber. The supply roller is disposed in the developing chamber. The replenishing port is located right above the supply roller when the developing apparatus is disposed in an orientation in which the developing apparatus is intended to be placed in a main casing of an image forming apparatus. The control unit controls the supply roller to rotate when the developing apparatus is mounted in the main casing. The supply roller stirs old developer that have already been located in the developing chamber and the new developer, and transports the old developer and the new developer from the developing chamber into the developer accommodating chamber. | 2009-08-06 |
| 20090196660 | DEVELOPING APPARATUS CAPABLE OF CONVEYING DEVELOPER UNIFORMLY AND DEVELOPER CONVEYER THEREOF - A developer conveyer for conveying developer includes a shaft, and a plate structure connected to the shaft. Flexural rigidity of a central part of the plate structure is less than flexural rigidity of a lateral part of the plate structure. Deformation of the central part of the plate structure is greater than deformation of the lateral part of the plate structure so that developer moves from the lateral part to the central part of the plate structure when the shaft drives the plate structure to rotate for conveying the developer. | 2009-08-06 |
