  • Patent number: 10060095
    Abstract: A hybrid work machine includes a controller and a temperature sensor that detects an electric storage device temperature. In a case where (Tp+Tc)?Te_min, the controller carries out a first comparison in which the controller compares a value of [(Tp+Tc)?Te_min] with a value of Ta_SOC, and the controller then selects a lower value of the first comparison. The controller then carries out a second comparison in which the controller compares the selected lower value of the first comparison with a value of [(Tp+Tc)?Te_max)]. The controller then sets a higher value of the second comparison as the torque of the assist motor Ta, wherein Tc is an accessory torque, Ta_SOC is an adjustment assist motor torque based on a current state of charge of the electric storage device, Ta is the torque of the assist motor, and Te_max is an engine maximum torque.

  • Publication number: 20150303719
    Abstract: Provided is a battery combined system in which a system operation rate is improved by reducing, in comparison with a conventional method, a frequency at which an SOC of a power type battery reaches an upper limit or a lower limit. The battery combined system according to the present invention is a battery combined system in which a capacity type battery and a power type battery having a higher output value with respect to a capacity (output/capacity) than that of the capacity type battery are connected in parallel. The battery combined system changes a threshold value to distribute charge/discharge power to the power type battery or the capacity type battery in the case where the charge/discharge power is equal to or less than maximum charge power and equal to or larger than maximum discharge power of the capacity type power.

  • Publication number: 20130344474
    Abstract: The novel means by which whether a subject has chronic hepatitis B or not can be determined easily with a high degree of accuracy is disclosed. The method for detection of chronic hepatitis B according to the present invention comprises measuring the amount of anti-HBc IgG in a sample separated from a subject. In this method, the measured amount of anti-HBc IgG which is not less than a predetermined cut-off value is indicative of chronic hepatitis B in the subject. The cut-off value may be a value not less than 40 IU/mL, e.g., a value selected from the range of 100 IU/mL to 200 IU/mL. By the present invention, chronic hepatitis B can be detected based on the amount of anti-HBc IgG without measuring the total amount of HBc antibodies including anti-HBc IgM.

  • Patent number: 6125443
    Abstract: An interrupt processing system and method for an information processing system of pipeline control type are disclosed. The occurrence of an exception is detected for each plurality of instructions to be processed in parallel. The occurrences of exceptions, when detected for a plurality of the instructions to be processed in parallel, are reported collectively according to each cause of the exceptions. In the case where the occurrences of exceptions are reported for a plurality of the instructions to be processed in parallel by an exception reporting unit, an interrupt request is issued. In response to the interrupt request, the pipeline processing is restored by an instruction control unit to the state before execution of the leading one of the plurality of the instructions to be processed in parallel for which the occurrences of exceptions are detected, and the instructions are reexecuted one by one sequentially from the leading one of the plurality of instructions through the instruction control unit.
