  • Publication number: 20200241988
    Abstract: An information processing apparatus includes: a plurality of control processing devices and a plurality of information processing devices. The control processing devices control operations compatibly with each other. The information processing devices perform various types of information processing through an interface shared by the control processing devices under control of any of the control processing devices. Before a first control processing device, which controls the information processing devices, is switched to a second control processing device among the control processing device, the second control processing device is set as a copy of the first control processing device. The information processing devices are sequentially switched to be controlled by the second control processing device in a period where the information processing devices do not execute tasks constituting the information processing.

  • Patent number: 8225854
    Abstract: A heat sink including a compact cooling system, superior uniformity of heating, provides a compact cooling unit superior in uniformity of cooling. A heat sink includes a header for distribution connected to a cooling fluid inlet, a header for confluence connected to a cooling fluid outlet and parallel to and adjacent to the header for distribution and a heat transfer vessel including a heating element mounting surface as well as channels inside. The channels are connected to the header for distribution and the header for confluence.

  • Patent number: 8107241
    Abstract: In a conventional cooling device, a heat pipe or a circulation-type liquid cooler provided with a pump is used and therefore, a large space is needed for the cooling device. There is provided a cooling device which includes a plurality of cooling modules having cooling units for cooling heat-generating elements by coolant and radiation units for radiating heat from the coolant heated in the cooling units, the plurality of cooling modules being bubble-pump-type ones in which the coolant is circulated between the radiation units and the cooling units by the coolant being boiled in the cooling units, the radiation units being arranged side by side, and a cooling fan for generating wind blowing the radiation units.

  • Patent number: 7881086
    Abstract: A power conversion device in which the inductance of a main circuit is reduced, a surge voltage is suppressed, elements are properly cooled, which is miniaturized and reduced in weight as a whole, and is excellent in handling performance in a manufacturing process and a maintenance work. A positive side arm unit includes IGBT modules, a coupling diode module, a cooling plate on which the modules are mounted, and a first laminated bus bar connected to the respective modules. A negative side arm unit includes IGBT modules, a coupling diode module, a cooling plate on which the modules are mounted, and a second laminated bus bar connected to the respective modules, and both the laminated bus bars and the capacitors are connected to one another by a third laminated bus bar. Both the cooling plates are parallel to each other so that the mount surfaces thereof are set in the same direction.
