  • Patent number: 10040224
    Abstract: An optical shaping method according to the present invention is an optical shaping method for shaping a three-dimensional structure by repeating a process for forming a cured resin layer 53 by irradiating an optically curing resin liquid 51 with light so that cured resin layers 53 are laminated. The process for forming the cured resin layer 53 includes, while applying a sheet light Ls to the optically curing resin liquid 51, applying a first light beam L1 intersecting the sheet light Ls to this optically curing resin liquid, and thereby forming the cured resin layer 53 in an area where the sheet light Ls intersects the first light beam L1. The irradiation place of the sheet light Ls is moved and the process for forming the cured resin layer 53 is repeated.

  • Patent number: 8676409
    Abstract: Even when a rigidity table stored in a RAM at the time of a start of a brake operation does not coincide with an actual rigidity characteristic of an electric caliper which changes according to brake conditions including how often and how long a brake operation is applied, it is possible to reduce a deviation between a pressing force instruction value and a generated pressing force by updating the characteristic of the relation between a pressing force instruction value and rotational position each time an estimated thrust force value is calculated during one brake operation. It is possible to steadily keep followability to a pressing force instruction according to an actual state of the rigidity characteristic of the electric caliper, thereby ensuring generation of an appropriate brake force.
