  • Patent number: 9863058
    Abstract: A gallium nitride crystal having a hexagonal crystal structure includes a first region located on an inner side of a cross section intersecting c-axis of the hexagonal crystal structure, and a second region surrounding at least a part of the outer periphery of the first region in the cross section. An emission spectrum of each of the first region and the second region with electron beam or ultraviolet light excitation has a first peak including a band edge emission of gallium nitride and a second peak located in a longer wavelength area than the first peak. A peak intensity of the first peak is smaller than a peak intensity of the second peak in the first region, and a peak intensity of the first peak is greater than a peak intensity of the second peak in the second region.

  • Publication number: 20160348272
    Abstract: In a method for manufacturing a group 13 nitride crystal, a seed crystal made of a group 13 nitride crystal is arranged in a mixed melt containing an alkali metal and a group 13 element, and nitrogen is supplied to the mixed melt to grow the group 13 nitride crystal on a principal plane of the seed crystal. The seed crystal is manufactured by vapor phase epitaxy. At least a part of contact members coming into contact with the mixed melt in a reaction vessel accommodating the mixed melt is made of Al2O3. An interface layer having a photoluminescence emission peak whose wavelength is longer than the wavelength of a photoluminescence emission peak of the grown group 13 nitride crystal is formed between the seed crystal and the grown group nitride crystal.

  • Patent number: 9505398
    Abstract: A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase.

  • Patent number: 9499159
    Abstract: A vehicle control apparatus uses a travel mode selection unit to select between an EV travel mode, an engine travel mode, and an engine generation mode depending on comparisons between an engine generated power cost, an EV effect, and a surplus electric energy. In such manner, according to a travel condition of a vehicle, an appropriate travel mode is selected for an improvement of fuel consumption efficiency. The vehicle control apparatus also computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes based on an engine efficiency and an MG-INV efficiency. In such manner, fuel consumption increase/decrease for every travel mode may be computed.

  • Patent number: 9430283
    Abstract: An information processing apparatus includes a storage unit and a processing unit. The storage unit is configured to store therein a first execution time and a second execution time longer than the first execution time. The first execution time is a time expected to be taken to execute a first job included in a first job group. The processing unit is configured to determine in which time period an execution start time of the first job is included. The execution start time is a time at which execution of the first job is to be started. The processing unit is configured to select, as a predicted execution time of the first job, one of the first execution time and the second execution time based on a result of the determination. The processing unit is configured to perform scheduling of the first job group based on the predicted execution time.

  • Patent number: 9404196
    Abstract: A method of manufacturing a group 13 nitride crystal includes a crystal growth process to form the group 13 nitride crystal by growing the group 13 nitride crystal having a hexagonal crystal structure from a seed crystal which is a gallium nitride crystal having a hexagonal crystal structure in which a length “L” in a c-axis direction is 9.7 mm or more, and a ratio L/d of the length “L” to a crystal diameter “d” in a c-plane is larger than 0.813. The crystal growth process includes a process of forming an outer periphery containing a {10-10} plane and an outer periphery containing a {10-11} plane at side surfaces of the group 13 nitride crystal, and forming an outer periphery containing a {0001} plane at a bottom surface of the group 13 nitride crystal.

  • Publication number: 20160218573
    Abstract: An electric rotary machine includes a stator, which Is fixed to a housing, composed of a stator core having a coil end protruding at an end face of the stator core, a rotor core formed by laminating core sheets, and a rotor having a pair of rotor side-plates sandwiching both end faces of the rotor core. The rotor core is rotatably supported in the housing facing an inner peripheral surface of the stator with a gap between the rotor core and the stator. Either one or both of the rotor side-plates has a concave surface in an outer surface of the side-plate that does not abut the rotor core. An axial distance from the end face of the rotor core to the concave surface increases from an inner diameter side to an outer diameter side.
