| 20090060500 | DATA PROCESSING SYSTEM AND STORAGE DEVICE - A storage device includes a memory that stores data, a memory controller that controls reading and writing of data from and to the memory, and a host controller. The host controller transmits and receives the data to and from a host via a transmission line. The host controller transmits and receives the data, via an optical transmission line, to and from (i) the memory controller and (ii) a memory controller of at least one other storage device. | 03-05-2009 |
| 20090101797 | OPTICAL SIGNAL TRANSMITTING APPARATUS, OPTICAL SIGNAL TRANSMITTING DEVICE, AND OPTICAL SIGNAL RECEIVING DEVICE - An optical signal transmitting apparatus includes a light-emitting element, a light-receiving section, a conductive line and a controller. The light-emitting element converts an electric signal into an optical signal. The light-receiving section converts the optical signal, which is received from the light-emitting element through an optical transmission medium, into an electric signal. The conductive line is connected to an output terminal of the light-receiving section. The light-receiving section outputs an analog signal through the output terminal. The controller controls an extinction ratio of the light-emitting element in accordance with a characteristic impedance of the conductive line. | 04-23-2009 |
| 20090196620 | STORAGE DEVICE, STORAGE DEVICE ARRAY, AND DATA PROCESSING SYSTEM - A storage device includes a storage section, a first control section, a communication section, a second control section and a wireless transmission and reception section. The storage section stores data. The first control section controls reading and writing the data from and into the storage section. The communication section transmits and receives the data to and from a higher-level device via a first transmission line. The second control section transmits and receives the data to and from the first control section and the communication section. The wireless transmission and reception section is provided to face a predetermined direction, and wirelessly transmits and receives data to and from another storage device provided in the predetermined direction under control of the second control section. | 08-06-2009 |
| 20100037021 | STORAGE DEVICE, STORAGE DEVICE ARRAY AND DATA PROCESSING SYSTEM - A storage device includes a data storage section, a first control section, a communication section, a second control section and a wireless transmission/reception section. The data storage section stores data. The first control section controls reading and writing the data from and into the data storage section. The communication section transmits and receives the data through a transmission line to and from a host device. The second control section transmits and receives the data to and from the first control section and the communication section. The wireless transmission/reception section is connected to the first and second control sections, is directed toward a predetermined direction, and wirelessly transmits and receives data to and from another storage device provided in the predetermined direction. | 02-11-2010 |

| 20090245887 | DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE COMPRISING THE SAME - To downsize a developing device in the developing carrier axial direction without generating image concentration irregularities from recirculation of developer in the magnetic roller end regions, an N2 pole and an N3 pole, which are mutually adjacent having the same polarity (N polarity), and which are for generating a magnetic force for removing from a developing sleeve a developer that has passed through a developing region, are provided on a magnetic roller. Magnets of this developing device, which are for generating a magnetic field to displace to the inside in the axial direction magnetic force lines that cause peeling force in the direction of separation from the developing sleeve to act on developer on the developing sleeve, based on the magnetic force of the N2 pole and the N3 pole, and that pass through the axial direction end regions within a developer separation region on the developing sleeve, are provided on the outside of the magnetic roller. | 10-01-2009 |
| 20110058858 | DEVELOPING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - There is provided a separation member for separating a first conveying path formed by a first conveying member from a second conveying path formed by a second conveying member. There is also provided an opposed member facing a magnetic pole H4 at an upstream side of two magnetic poles H4 and H6 that forms a developer-releasing magnetic pole H5. | 03-10-2011 |
| 20110194874 | DEVELOPMENT DEVICE, AND PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A development device includes a developer container, a developer carrier, exposed partly from a casing, facing a latent image carrier in a development area, a magnetic field generator inside the developer carrier, having multiple magnetic poles including a conveyance pole to convey the developer downstream from the development area to a developer release portion, a developer agitator, and a developer regulator. A predetermined gap is kept between an outer surface of the developer carrier and an inner wall of the casing downstream from an opening of the casing, upstream from a developer release portion, in a direction in which the developer carrier rotates. Multiple recesses are formed in the outer surface of the developer carrier at a pitch in a circumferential direction shorter than half a width of a magnetic flux density of the developer conveyance pole in a direction perpendicular to an axial direction of the developer carrier. | 08-11-2011 |
