  • Patent number: 11136064
    Abstract: A rotation detection device includes a plurality of detectors each including a plurality of calculators respectively calculating a detection value. A control unit of the rotation detection device monitors abnormality of detection values respectively detected by the plurality of detectors, and, when determining abnormality, identifies a calculator calculating an abnormal detection value based on a result of comparison between the detection values of the plurality of calculators. Then, the control unit continues calculation of an absolute angle by using the detection values from the calculators other than the identified calculator.

  • Patent number: 9489843
    Abstract: In order to enable information about dangers from the perspective of users using various means of transportation to be collected, a map provision server (1) is equipped with: a data acquisition unit (11) that acquires from multiple vehicles (20) driving information (FCD) containing instances of sudden braking and the locations where the sudden braking occurred; a dangerous location identification unit (121) which, on the basis of the acquired driving information, identifies dangerous locations (41) where many instances of sudden braking have occurred; and a posting column generation unit (122) that places the dangerous locations (41) on a map and generates a posting column (60) capable of receiving postings from users and associated with the dangerous locations (41) placed on the map. The map on which the dangerous locations (41) have been placed is provided to a user terminal (4).

  • Patent number: 8668843
    Abstract: An M-C—N—O based phosphor including a group IIIB element (M), carbon (C), nitrogen (O), wherein an amount of the group IIIB element (M) contained is 1%<(M)<50% by mass, an amount of carbon (C) contained is 0.005%<(C)<10% by mass, an amount of nitrogen (N) contained is 1%<(N)<60% by mass, an amount of oxygen (O) contained is 1%<(O)<75% by mass, and (M)+(C)+(N)+(O)=100% by mass. Colors of the M-C—N—O based phosphor can be changed by adjusting a peak top of an emission spectrum. Highly environmentally-compatible polymer dispersions, inorganic EL devices, light emitting devices, fluorescent tubes, and the like are also provided, which use the M-C—N—O based phosphors.

  • Publication number: 20100109508
    Abstract: M-C—N—O based phosphors having high emission intensity are provided without using heavy metals, rare metals, and special activator agents. Colors of the M-C—N—O based phosphors can be changed by adjusting a peak top of an emission spectrum. Highly environmentally-compatible polymer dispersions, inorganic EL devices, light emitting devices, fluorescent tubes, and the like are also provided, which use the M-C—N—O based phosphors. The M-C—N—O based phosphors of the present invention comprise a group IIIB element (M), carbon (C), nitrogen (N), and oxygen (O). Colors are changed by changing an amount of carbon (C) contained in the M-C—N—O based phosphors. The polymer dispersions, inorganic EL devices, light emitting devices, and fluorescent tubes are produced using the M-C—N—O based phosphors.
