Abstract: There is provided a request arbitration apparatus for arbitrating a plurality of request holding sections which hold requests having priorities when the requests are output from the plurality of request holding sections to the output device. The request arbitration apparatus includes: a setting section that sets the request holding section, which holds the highest priority request among all the requests held by the plurality of request holding sections, as a highest priority request holding section; and a control section that controls the highest priority request holding section so that the request held first among all the requests held by the highest priority request holding section is output to the output device.

Abstract: An image processing apparatus includes a plurality of cores that carry out binarization processes while shifting a target pixel from the first pixel in a processing line in order toward the last pixel in the processing line in accordance with a diffusion of error that takes unprocessed pixels surrounding the target pixel including the pixels of the following line of the processing line as a diffusion range; of the plurality of cores, the core that processes the following line carries out the binarization process in order while delaying the target pixel at least by an amount equivalent to the diffusion range relative to the target pixel of the core that processes the previous line. Accordingly, the lines can be processed in parallel while reflecting the error appropriately on the unprocessed pixels, and thus the binarization process using error diffusion can be carried out more quickly.

Abstract: There is provided a signal synchronization method of performing signal synchronization between a device which operates in synchronization with a first clock signal and a processor which operates in synchronization with a second clock signal with a different cycle from that of the first signal.

Abstract: A multi-processor system includes two or more processors, a message box in which messages are stored which have been sent from a transmitting processor to a receiving processor, which each correspond to one of the two or more processors, at an address in a matrix form which correspond to the transmitting processor and the receiving processor, and an interrupt signal output unit which outputs an interrupt signal to the receiving processor when a message is written in the message box.

Abstract: An ink cartridge supported on a housing portion includes a non-volatile memory. The non-volatile memory communicates with a control portion mounted to a recording apparatus main body through a memory access controlling portion as an interface.

Abstract: A carriage (recording head portion) which an ink cartridge including a non-volatile memory is to be mounted has a memory access controlling portion for controlling accesses to a non-volatile memory, thereby reducing the number of connection lines between the carriage (recording head portion) and a printer main body controlling portion. The apparatus main body controlling portion and the memory access controlling portion transmit and receive data therebetween by means of serial data communication. The memory access controlling portion reads out various information (the amount of remaining ink, use start year and month, and the like) stored in each non-volatile memory and then stores the readout information in a RAM in the memory access controlling portion. The apparatus main body controlling portion issues an access request command for the RAM to read information out from the RAM and update the readout information.

Abstract: An apparatus main body controlling section 2 and a memory access controlling section 3 transmit and receive data by means of serial data communication. The memory access controlling section 3 reads various information (the amount of remaining ink, use start year and month, and the like) stored in non-volatile memories 4 and 5 and stores the readout information in a RAM in the memory access controlling section 3. The apparatus main body controlling section 2 issues an access request command to the RAM to read out and renew the information. When a power supply to a printer is turned off, the apparatus main body controlling section 2 issues an information write back command. The memory access controlling section 3 writes the information in the RAM back to the non-volatile memories 4 and 5.

Abstract: The present invention relates to a process for producing an anode for a secondary battery, which is capable to reduce a contact resistance between a sintered material which contains silicon as an anode active material and a current collector. A binder and a solvent are mixed with a silicon-containing anode material to prepare a slurry. A base material made of a foil or mesh of conductive metal is coated with the slurry, and the solvent is removed to form a coated film. The coated film is sintered in a non-oxidizing atmosphere, thereby integrating a sintered material of the coated film with the base material.

Abstract: The present invention relates to a lithium secondary battery with a cathode and an anode, each electrode containing an active material capable of incorporating and releasing lithium ions. The anode includes a sintered material which contains 50 to 99 % by weight of silicon and 1 to 50% by weight of carbon material, and has an electrical conductivity not less than 1 S/cm. By employing the anode including the sintered material containing silicon as the anode active material and carbon material, an increased packing density of the active material and an increased capacity per volume can be obtained. Furthermore, the anode conductivity of not less than 1S/cm can provide a high capacity and improved cycle property.
