    Abstract: During epitaxial growth of an n?-type drift layer having a uniform nitrogen concentration, vanadium is doped in addition to the nitrogen, whereby an n?-type lifetime reduced layer is selectively formed in the n?-type drift layer. The n?-type lifetime reduced layer is disposed at a depth that is more than 5 ?m from a pn junction surface between a p-type anode layer and the n?-type drift layer in a direction toward a cathode side, and the n?-type lifetime reduced layer is disposed separated from the pn junction surface. Further, the n?-type lifetime reduced layer is disposed in a range from the pn junction surface to a depth that is ? times a thickness of the n?-type drift layer. A vanadium concentration of the n?-type lifetime reduced layer is 1/100 to ? of a nitrogen concentration of the n?-type lifetime reduced layer.

  • Publication number: 20190347879
    Abstract: An image display system includes a first processor, a second processor, and a comparator. The first processor acquires a behavior estimation result of a vehicle, and generates future position information after a predetermined time passes of the vehicle based on the behavior estimation result. The second processor acquires present information about the vehicle, and generates present position information on the vehicle and a peripheral object based on the acquired information. The comparator compares the future position information on the vehicle and the present position information on the vehicle and the peripheral object, and generates present image data indicating present positions of the vehicle and the peripheral object and future image data indicating future positions of the vehicle and the peripheral object. Further, the comparator allows a notification device to display a present image based on the present image data and a future image based on the future image data together.

  • Publication number: 20190344798
    Abstract: An information processing system includes a safe behavior determiner, clustering range controller, and safety determiner. The safe behavior determiner classifies parameter values indicating a travel state of a vehicle into multiple ranges based on travel safety. The safe behavior determiner also determines a safe behavior for the vehicle by which the travel state of the vehicle is adjusted such that the parameter values fall under a safety range with high travel safety. The clustering range controller changes a position of a boundary between the ranges according to an external environment of the vehicle. The safety determiner acquires a behavior estimation result of the vehicle and the safe behavior determined by the safe behavior determiner, and determines behavior control of the vehicle on the basis of at least the acquired behavior estimation result or safe behavior.

  • Patent number: 10444737
    Abstract: A numerical controller operates a machine tool based on a plurality of parameters and a machining program. A user is allowed to refer to a parameter that has not been set, in other words, a parameter not falling within the range of recommended setting values, among parameters that may influence the shortening of a cycle time of the operation of the machining program on a display screen. For this reason, the user can use the parameter as a reference for reviewing the parameter setting for the purpose of shortening the cycle time or the like.

  • Publication number: 20190237547
    Abstract: On a front surface of an n+-type starting substrate containing silicon carbide, a pin diode is configured having silicon carbide layers constituting an n+-type buffer layer, an n?-type drift layer, and a p+-type anode layer sequentially formed by epitaxial growth. The n+-type buffer layer is formed by so-called co-doping of nitrogen and vanadium, which forms a recombination center, together with an n-type impurity. The n+-type buffer layer includes a first part disposed at a side of a second interface of the buffer layer with the substrate and a second part disposed at side of a first interface of the buffer layer with the drift layer. The vanadium concentration in the second part is lower than that in the first part. The vanadium concentration in the second part is at most one tenth of the maximum value Vmax of the vanadium concentration in the n+-type buffer layer.
