| 20080240799 | DESKTOP COLOR IMAGE FORMING APPARATUS AND METHOD OF MAKING THE SAME - The present invention relates to an electrophotographic color image forming apparatus using a tandem-drum development, an indirect image-transfer method, and a vertical sheet supply path. An intermediate image-transfer member is angled relative to a horizontal line such that a rear side of the intermediate image-transfer member away from a recording sheet is lifted and a front side of the intermediate image-transfer member closer to the recording sheet is lowered. Further, image creating mechanisms of the tandem-drum development are aligned and arranged in parallel to a moving image transfer bed of the intermediate image-transfer member, such that one of the image creating mechanisms firstly forming an image faces the rear side of the moving image transfer bed and another one of the image creating mechanisms lastly forming an image faces the front side. | 10-02-2008 |

| 20110055463 | SEMICONDUCTOR DEVICE AND DRIVING METHOD THE SAME - It is an object to prevent miswriting by radio in a relatively easy way in a semiconductor device which is capable of data communication (reception/transmission) through wireless communication, in particular, in an RFID tag provided with an OTP memory or a write-once memory. Alternatively, it is an object to prevent data from being tampered. Further alternatively, it is an object to inhibit access to a memory in a relatively easy way and to inhibit reading of data in a semiconductor device which is capable of data communication (reception/transmission) through wireless communication. In a semiconductor device including a control circuit and an OTP memory, a memory includes at least a sector for preventing additional writing and an information sector. When data for preventing additional writing is written to the sector for preventing additional writing and information is written to the information sector which is electrically connected to the sector for preventing additional writing, additional writing to the information sector to which the information is written is impossible. | 03-03-2011 |

| 20100183310 | DISPERSION COMPENSATOR - Conventional dispersion compensators were not sufficient to satisfy a demand to set a different dispersion value for each WDM wavelength in a ring-mesh type network that utilizes wavelength selective switches or the like. The devices were insufficiently reduced in size and power consumption and used with difficulty to change dispersion characteristics for each wavelength flexibly in a simple manner. A dispersion compensator of the present invention uses general-purpose optical components including a spatial light modulator for providing discrete phases to set appropriately the relationship between the focusing beam radius and the spatial light modulator pixel, thereby providing various dispersion compensation characteristics. Attention is focused on the correspondence between multiple pixels on the spatial light modulator providing discrete phases and a communication channel band, thereby allowing for changing the flexible dispersion characteristics and realizing the setting of an independent dispersion value for each WDM wavelength. | 07-22-2010 |
| 20100316385 | OPTICAL SIGNAL PROCESSING DEVICE - A conventional optical signal processing device had a disadvantage where the temperature dependency of the spectroscopic characteristics of a spectroscopic element causes a deteriorated performance. In order to solve the temperature dependency, there has been a method to form a plurality of grooves for dividing a core on the array waveguide of the AWG. However, this method cannot avoid an excess loss and causes a high manufacture cost. By directly controlling the modulation characteristic profile formed by an element device of a spatial light modulator, athermalization can be achieved in a simpler and low-cost manner. This consequently provides a remarkable reduction of the light coupling loss in the spatial optical system of the optical signal processing device. More accurate temperature compensation can be realized that copes with an actual behavior of the device to a temperature fluctuation, including causing factors of a complicated temperature fluctuation of the optical system. | 12-16-2010 |
| 20110228374 | OPTICAL SIGNAL PROCESSING DEVICE - In a conventional optical signal processing device, a confocal optical system is configured in which a focusing lens is positioned at a substantially-intermediate point of a free space optical path. Thus, the free space optical system had a long length. It has been difficult to reduce the size of the entire device. The optical signal processing device of the present invention uses a lens layout configuration different from the confocal optical system to thereby significantly reduce the length of the system. The optical signal processing device consists of the first focusing lens positioned in the close vicinity of a signal processing device, and the second focusing lens positioned in the vicinity of a dispersing element. A distance between the dispersing element and the signal processing device is approximately a focal length of the first focusing lens. Compared with the conventional technique, the length of the optical path can be halved. | 09-22-2011 |

| 20100013960 | SIGNAL PROCESSING APPARATUS AND IMAGE DATA GENERATION APPARATUS WITH ELECTRONIC REDUCTION AND ENLARGEMENT SIGNAL PROCESSING CAPABILITIES - A recording mode control circuit controls a first recording mode in which still image data having a first image size corresponding to the number of pixels of an image sensing element is generated and recorded and a second recording mode in which moving image data having a second image size smaller than the first image size is generated and recorded. In generating the moving image data in the second recording mode, a camera signal processing circuit executes electrical zoom processing to obtain the second image size. At this time, a maximum magnification ratio setting circuit sets the maximum variable magnification ratio of electrical zoom processing in the camera signal processing circuit. With this processing, an image recording apparatus which allows a user to select a zoom mode with a small degradation in image quality in electrical zoom processing can be implemented. | 01-21-2010 |
