  • Publication number: 20160056260
    Abstract: A method for manufacturing a semiconductor device includes forming a thermal oxide film on one surface of an SiC substrate by thermal oxidation at a temperature of 1150° C. or above in a gas atmosphere including nitrogen and oxygen, and introducing highly-concentrated nitrogen to one surface of the SiC substrate while forming the thermal oxide film; forming a highly-concentrated n-type SiC layer on one surface of the SiC substrate such that the thermal oxide film is removed from one surface of the SiC substrate by etching and, thereafter, one surface of the SiC substrate is exposed to radicals so that Si—N bonded bodies and C—N bonded bodies on one surface of the SiC substrate are removed while leaving nitrogen introduced into a lattice of SiC out of highly-concentrated nitrogen introduced into one surface of the SiC substrate; and forming an ohmic electrode layer on one surface of the SiC substrate.

  • Patent number: 7273414
    Abstract: A loop track for racing objects is disposed at the center of a race game device, for example for a simulated horse race. A plurality of racing objects, such as race horses, run on the track. The X- and Y-directional positions of the race horses are detected by a separable position detecting means underlying the track. The separable position detecting means allows for easier maintenance, transport, assembly, and disassembly of the device. Information regarding the positions of the horses is displayed on a game screen. Players can write memos to themselves on individual game screens by pressing a trace over the game information on the game screen. A control unit provides game information corresponding to other races other than a current race, including future races, and players may select information corresponding to future races on the individual game screen.

  • Patent number: 5976019
    Abstract: A traveling simulator capable of controlling in real time the movements of model traveling members, irrespective of a traveling speed of a carrier, is disclosed. The model traveling members, modeled after actual traveling objects, are placed moveably on a traveling plate, and the moveable carrier is disposed below the traveling plate. These model traveling members are tracted by the carrier via the attractive force between magnets provided on a lower surface of the traveling members and magnets provided on an upper surface of the carrier. The magnets on the side of the carrier and those, which are opposed to the magnets on the side of the model traveling members consist of magnets rotatable around vertical shafts. These magnets are provided on the sides of the model traveling members and carrier, two each respectively, so that each set of magnets are spaced from each other.
