  • Patent number: 11319846
    Abstract: An oil separator is provided, which can accurately control an interval between an introduction hole of a gaseous body and a separation member, and can ensure a stable and high separation performance. An oil separator 30 includes a wall portion 31 having a plurality of orifices 32, and a holding portion 34 holding a separation member 33. A facing surface 33A of the separation member 33 is disposed along a front face portion 42A of a positioning portion 42 having a plurality of opening portions 42D, so that an interval L between the orifices 32 and the facing surface 33A of the separation member 33 accurately has a desired distance. A gas separated from an oil smoothly flows downward along a flow path formed by the opening portions 42D so as to reduce a pressure loss.
    Type: Grant

  • Patent number: 9363196
    Abstract: The present invention is provided with: a data-driven processor comprising at least a firing control which determines whether or not firing conditions have been met by determining whether or not all packets necessary for instruction execution have been received when a packet that convey a part of partitioned data to be processed has been input, and a data processing unit for performing processing corresponding to the packets transmitted from the firing control if the firing conditions have been met; a power supply circuit for supplying power to the data-driven processor; and overload avoidance means for refusing input of the packets to the data-driven processor, if a determination has been made that a data processing load in the data-driven processor may reach an overloaded state in which the data processing may stall, on the basis of current consumption in the data-driven processor. Accordingly, power consumption in a networking system is reduced.
