  • Publication number: 20240144700
    Abstract: A moving body control device includes an outside recognition unit configured to acquire recognition data of an outside of a moving body, a reception unit which receives designation of a predetermined parking position from a user of the moving body, and a control unit configured to perform automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and register the predetermined parking position as a designated parking position. The control unit is configured to register feature points related to the designated parking position by using a plurality of patterns based on illuminance of the outside calculated from the recognition data of the outside.

  • Publication number: 20240135725
    Abstract: A control device for a moving body includes an outside recognition unit, a parking candidate position detection unit, and a reception unit. The parking candidate position detection unit is configured to be able to execute a first detection process of detecting an unregistered parking candidate position and a second detection process of detecting a registered parking candidate position, start the first detection process based on an operation by the user, stop the first detection process when detecting that a movement speed of the moving body during movement of the moving body becomes equal to or less than a predetermined speed, and start the second detection process based on stopping of the first detection process.

  • Patent number: 11806786
    Abstract: A stress controlled layer is constituted to include a compressive stress applied part that is a region to which a compressive stress is applied and a compressive stress non-applied part that is a region different from the compressive stress applied part. In a solidifying step, scanning of a laser beam or an electron beam is performed while a scanning direction for the compressive stress applied part is different from a scanning direction for the compressive stress non-applied part such that the compressive stress applied part expands further than the compressive stress non-applied part or the compressive stress non-applied part shrinks compared with the compressive stress applied part based on a relationship between the scanning direction and an expansion quantity or a shrinkage quantity at a time of temperature change or at a time of heat treatment.

  • Patent number: 6205111
    Abstract: A disk driving apparatus provided by the present invention comprises: a motor; a turntable mounted on the rotational shaft of the motor, the turntable used for mounting and driving into rotation a multi-disk set comprising a plurality of disk plates stuck to each other; and a disk holding mechanism comprising a fixed portion with such a height that only a particular one of the disk plates of the multi-disk set to be mounted on the turntable is brought in contact with the fixed portion, and a movable portion capable of moving in the radial direction of the turntable in contact with the particular disk plate. As a result, even a multi-disk set can be centered at the center of the turntable with a high degree of accuracy by means of a centering mechanism having a simple configuration which can be implemented at a low cost.
