  • Publication number: 20180251910
    Abstract: A manufacturing method of an SiC composite substrate 10 that includes a single crystal SiC layer 12 on a polycrystalline SiC substrate 11. After manufacturing a single crystal SiC layer supporting body 14 by providing the single crystal SiC layer 12 on one surface of a holding substrate 21 including Si. A polycrystalline SiC is deposited on the single crystal SiC layer 12 through chemical vapor deposition to manufacture an SiC laminated body 15 laminated with the single crystal SiC layer 12 and the polycrystalline SiC layer 11 having a thickness t on the holding substrate 21?. At the same time, the single crystal SiC layer supporting body 14 is heated at a temperature less than 1,414 degrees Celsius, and a portion of the thickness t of the polycrystalline SiC is deposited.

  • Patent number: 9189431
    Abstract: A network system enables monitoring the status of peripheral devices from computers without concentrating a load on the network. A specific device driver that runs on a specific computer connected to the network has an initialization command transmission unit that sends a first initialization command to the specific printer when a process command is sent to a specific printer, and an operating status monitoring unit that, after initialization based on the first initialization command is completed, monitors the operating status of the specific printer until the printer power turns off. Because the specific computer does not initialize and does not monitor the operating status of the specific printer until the computer sends a process command, concentrating a load on the network is avoided when the network system starts up.

  • Patent number: 9098779
    Abstract: A host computer is connected to a printer that prints text according to settings specifying a text printing format. Using a function of a driver setup program, the host computer acquires a file set including an MOT file (recording device settings data) and a corresponding INF file (control device settings data) that are configured to produce the same or substantially the same printout as a printer with different printing format specifications, and configures settings stored in a registry that is referenced by a printer driver based on the acquired INF file. Using a function of a firmware setup program, the host computer generates or updates settings based on the MOT file.
