  • Patent number: 9701302
    Abstract: In a vehicle energy management device, a travel route calculator calculates a travel route of a vehicle, and an energy consumption-related information obtaining unit obtains energy consumption-related information along the travel route. An energy consumption amount computing unit calculates, based on the energy consumption-related information, an estimated value of an energy consumption amount by vehicle devices (required travel energy amount) when the vehicle travels along the travel route. A control plan preparing unit prepares a control plan for the vehicle devices based on the required travel energy amount. A feedback control unit performs feedback control of the vehicle devices to reduce a difference between the estimated value and an actual measured value of the energy consumption amount by the vehicle devices.

  • Publication number: 20160225913
    Abstract: Transistors using nitride semiconductor layers as channels were experimentally manufactured. The nitride semiconductor layers were all formed through a sputtering method. A deposition temperature was set at less than 600° C., and a polycrystalline or amorphous InxGayAlzN layer was obtained. When composition expressed with a general expression InxGayAlzN (where x+y+z=1.0) falls within a range of 0.3?x?1.0 and 0?z<0.4, a transistor 1a exhibiting an ON/OFF ratio of 102 or higher can be obtained. That is, even a polycrystalline or amorphous film exhibits electric characteristics equal to those of a single crystal. Therefore, it is possible to provide a semiconductor device in which constraints to manufacturing conditions are drastically eliminated, and which includes an InGaAlN-based nitride semiconductor layer which is inexpensive and has excellent electric characteristics as a channel.
