  • Publication number: 20200265052
    Abstract: It is possible execute processing large-scale data and improve the processing efficiency while suppressing the complexity of a hardware circuit. A data processing device includes a processor and a FPGA connected to the processor. The processor is configured to acquire a query plan including target identification information identifying data to be processed and a processing detail for the data to be processed, generate, based on the query plan, a plurality of FPGA commands to process a plurality of row group data items constituting the data identified by the target identification information and to be processed, and transmit the FPGA commands to the FPGA. The FPGA is configured to execute processing on the row group data items based on the transmitted FPGA commands and return results of executing the processing to the processor.

  • Publication number: 20200071863
    Abstract: Provided is a fiber reinforced plastic member made by a braiding technique to obtain high rigidity and superior vibration damping performance under a bending load. A reinforcing member made of carbon fiber reinforced plastic resin extends in a specific direction along an axis of the reinforcing member and includes a carbon fiber braided structure. The carbon fiber braided structure has a structure in which a plurality of axial yarns, a plurality of first braid yarns, and a plurality of second braid yarns are braided. A plurality of first braid yarns are wound to intersect the axis at a first braid angle. A plurality of second braid yarns are wound to intersect the axis at a second braid angle. The first braid yarns and the second braid yarns intersect each other.

  • Patent number: 10363882
    Abstract: A temporary fixing unit includes a supporting portion including a distal end portion passed through an aperture, and a holding portion provided with an inclined surface that slides along an edge portion of the aperture when passed through the aperture. The temporary fixing unit also includes a spring portion connecting the distal end portion of the supporting portion and the holding portion and that deforms in a twisted manner as the holding portion is pushed down when the inclined surface of the holding portion slides along the edge portion of the aperture. When the holding portion is passed through the aperture, a portion of a door panel is held between the holding portion and an elastic portion. Furthermore, the elastic portion is elastically deformed so as to press the door panel.

  • Publication number: 20190228009
    Abstract: An accelerator is mounted on each server which is a worker node of a distributed DB system; a query generated by an application of an application server is divided into a first task that should be executed by the accelerator and a second task that should be executed by software and is allocated to the server of the distributed DB system; the server causes the accelerator to execute the first task, and executes the second task based on the software.

  • Publication number: 20190161068
    Abstract: A multiple drive source-equipped vehicle includes two temperature detection parts configured to detect a temperature of external air. When a heating operation is performed at a time of vehicle driving by a first drive source, the controller determines whether or not an external air temperature is lower than a predetermined value based on a detection temperature of a temperature detection part of which a detection temperature is higher among the two temperature detection parts. The controller continues a heating operation by a first heating apparatus when it is determined that the external air temperature is not lower than the predetermined value. The controller operates the second drive source and performs a heating operation by a second heating apparatus when it is determined that the external air temperature is lower than the predetermined value.
