  • Patent number: 9857782
    Abstract: A first acquiring unit acquires initial output values of a physical quantity sensor. A second acquiring unit acquires target output values for the physical quantity sensor. A first calculating unit extracts first characteristic values by calculating a second-order first characteristics formula which indicates corrected output characteristics of the physical quantity sensor, based on the initial output values and target output values of the physical quantity sensor. The second calculating unit extracts second characteristic values by calculating a second-order second characteristics formula for correcting the first characteristic values, based on a predetermined temperature and the first characteristic values. A computing unit computes a corrected output value for the physical quantity sensor based on the first characteristics formula which is corrected by inputting the second characteristic values to the second characteristics formula.

  • Patent number: 8542384
    Abstract: An image processing apparatus includes a receiving unit, a recognition unit, a calculation unit, a determination unit, and a controller. The receiving unit receives a print job. The recognition unit recognizes hardware information regarding the image processing apparatus. The calculation unit calculates a time required for image processing of the received print job in accordance with the recognized hardware information and image data in the print job. The determination unit determines whether or not the calculated time required for the image processing of the print job is shorter than a predetermined time. The controller performs assignment control so that, when the determination unit determines that the time required for the image processing of the print job is not shorter than the predetermined time, a dynamic reconfigurable processor included in another image processing apparatus processes a portion of the print job.

  • Publication number: 20110290228
    Abstract: A warm air furnace prevents household articles from freezing in the case where combustion is discontinued due to lack of gas during combustion operation when a house is emptied. The warm air furnace is equipped with a retry operation controller 33 which carries out ignition action of a combustor 5, in the case where a predetermined period of time lapsed from the time it is determined that combustion at the combustor 5 is discontinued during combustion operation by a combustion operation controller which controls operation of the combustor, determines whether or not combustion at the combustor 5 is started, and repeats the ignition action for igniting the combustor 5 until it is determined that combustion at the combustor 5 is started, in the case where a predetermined time lapsed from the time it is determined that the combustion at the combustor 5 is not started.

  • Publication number: 20110057047
    Abstract: A hot air heater has a housing having formed therein an inlet port for sucking room air and an outlet port. A circulation fan, a burner, and a heat exchanger which causes to flow combustion gas from the burner through an inside of the heat exchanger are housed in the housing. The room air sucked by operation of the circulation fan into the inlet port is heated by the heat exchanger for blowing forward as hot air out of the outlet port. A supporting plate is disposed to support the heat exchanger inside the housing. In order to limit the temperature increase in the housing by heat transmission through the supporting plate, and in order to improve the thermal efficiency, the supporting plate is provided with radiating fins. Preferably, the radiating fins are made up of cut-and-raised pieces formed in the supporting plate.

  • Patent number: 7843107
    Abstract: A dynamoelectric machine including first and second permanent magnets held by first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces. The dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.
