  • Patent number: 10913402
    Abstract: An interior component includes: an interior component body; and a mount structure for mounting the interior component body on a vehicle body. The mount structure includes: a leg part extending from the interior component body; a guide part provided at a tip of the leg part; a pair of elastic engaging hooks extending from the guide part toward the interior component body while being spaced apart from and opposing to each other; and a slit provided between the leg part and one of the elastic engaging hooks. An interval in a spaced-apart direction of the pair of elastic engaging hooks is equal to or greater than a dimension in the spaced-apart direction of the leg part. Hence, the slide molds are shifted in parallel to each other in the long-side direction of the interior component body to be removed. Thus, the mount structure is formed.

  • Patent number: 10868744
    Abstract: An influence range identification apparatus includes a processor configured to acquire information indicating a first device in which a failure occurs. The processor searches for second devices starting from the first device based on a connection relationship among a plurality of devices. The second devices exist in a first influence range. The processor determines whether a third device exists among the second devices. The third device has abnormality due to the failure. The processor determines whether each of the second devices other than the third device exits in a second influence range starting from the third device based on the connection relationship among the second devices. The processor determines a rank of a degree of a possibility of being affected by the failure with respect to each of the second devices other than the third device.

  • Publication number: 20200076453
    Abstract: A signal source (44) supplies local signals having different phases to a first mixer (42) and a second mixer (43). The first mixer (42) and the second mixer (43) perform frequency conversion on reception signals using the local signals. A first phase changing unit (51) and a second phase changing unit (52) receive output signals of the first mixer (42) and the second mixer (43) as input signals and generate in-phase and reversed phase signals of these signals. A first adder (53) adds output signals of the first phase changing unit (51) to separate multiple signals. A second adder (54) adds output signals of the second phase changing unit (52) to separate multiple signals.
