  • Publication number: 20100245893
    Abstract: An image forming apparatus includes: a communication unit that receives a request that requests a reply and includes a source of the request and a destination of the request; and a controller that returns from a low electric power condition after moving into the low electric power condition of which the power consumption is low, and that controls the communication unit, wherein when the controller is in the low electric power condition, the communication unit returns the reply to the request received and detects a duplication between an identification information that identifies the source and an identification information that identifies the destination based on the request.

  • Publication number: 20100246380
    Abstract: A communication control device includes: a first processing unit that converts an electrical signal received by a communication channel into digital data and outputs the digital data, and in a second operation mode in which an amount of power supplied to the communication control device is lower than in a first operation mode, outputs a notification signal upon receiving an electrical signal indicating an arrival of packet data; a clock controller that, in the second operation mode, initiates supplying a clock signal upon receiving the notification signal; and a second processing unit that (i) has a receiving unit that extracts packet data from the digital data and outputs the extracted packet data, and (ii) in the second operation mode, stops receiving packet data during a time that the clock signal is not supplied, and upon reception of the clock signal, starts receiving packet data using the received clock signal.

  • Publication number: 20100250811
    Abstract: An interrupt controller includes: a timer that repeatedly measures a predesignated length of time; an interrupt request unit that, when data is received by a receiving unit while the timer is measuring the length of time, outputs an interrupt request after measurement of the length of time is completed; a measurement unit that measures a frequency of data reception of the receiving unit; and an updating unit that changes the length of time measured by the timer so as to be shorter than the predesignated length of time when the frequency of reception measured by the measurement unit exceeds a threshold frequency.

  • Publication number: 20100241778
    Abstract: An interrupt control apparatus includes: an interrupt request supply unit that supplies interrupt request information; a processing unit that performs interrupt processing based on the interrupt request information supplied by the interrupt request supply unit; and a time measuring unit that is used to measure an elapse of a predefined time period from a time point when the interrupt request supply unit starts to supply the interrupt request information, wherein: even if new interrupt cause information is stored during the time when the time measuring unit is measuring the elapse of the predefined time period, the interrupt request supply unit does not supply interrupt request information based on the new interrupt cause information to the processing unit; and after the elapsed time measured by the time measuring unit reaches the predefined time period, the interrupt request supply unit supplies the interrupt request information to the processing unit.

  • Publication number: 20100128305
    Abstract: A receiver includes a first storage unit, plural second storage units, a selector, a storage controller, and a selection controller. The first storage unit stores at least one packet data. The plural second storage units respectively store at least one condition associated with packet data to be stored in the first storage unit. The selector selects at least one storage unit from the second storage units in accordance with a selection signal. The storage controller stores the packet data in the first storage unit if a received packet data corresponds to any condition stored in a selected storage unit, and discards the packet data if it does not correspond to any condition. The selection controller generates a selection signal for selecting at least one second storage unit in accordance with conditions to which the packet data stored by the storage controller corresponds, and transmits the signal to the selector.

  • Patent number: 7589147
    Abstract: The present invention is characterized by a resin composition for a thermal conductive material including a polymer (I), a liquid-state plasticizer (II) and a thermal conductive filler (III) having a thermal conductivity of 20 W/m·K or more, wherein the liquid-state plasticizer (II) is in a liquid state at 25° C., and has a mass loss rate of 2 mass % or less when kept at 130° C. for 24 hours. By using this resin composition for a thermal conductive material, it becomes possible to obtain a thermal conductive material having superior thermal conductivity and flexibility.

  • Publication number: 20090073490
    Abstract: A communication information processing device that includes a reception component, an image processing component, a memory component and a control component is provided. The reception component receives communication information through an external communication line. The image processing component performs image processing on image information. The memory component is provided for memorizing image information for image processing by the image processing component, and that memorizes image information and the communication information received by the reception component. The control component, when a pre-specified setting condition is satisfied, controls the memory component so as to delete the communication information memorized in the memory component and to memorize image information to be used by the image processing component as a priority.
