  • Patent number: 10759304
    Abstract: A vehicle seat includes: a leg member, attached to a lower end portion of a seat main body movable between use and stowed positions and movable along with a seat main body, and a leg holding member, elastically deformable to hold a holding target portion of the leg member. The leg holding member includes separated first and second portions which are configured to hold the holding target portion having passed through an introduction opening of the leg holding member formed between the first and second portions with the holding target portion interposed between the first and second portions when the leg member moves along with the seat main body moving toward the use position. A deformation amount restriction portion restricts deformation generated when the leg holding member is elastically deformed so that the first and second portions are separated when the holding target portion passes through the introduction opening.

  • Patent number: 10228843
    Abstract: An image processing apparatus includes a display for displaying operational information for executing image processing, an operation unit for giving an input instruction in association with a display region appearing on the display, and a controller for controlling the display in accordance with the input instruction on the operation unit. The controller is configured to determine whether an input instruction of a flick operation is given through the operation unit in association with a prescribed display region appearing on the display. If it is determined that the input instruction of the flick operation is given, the controller is configured to enlarge a range of the prescribed display region in which the input instruction is allowed, and to display the enlarged display region on the display.

  • Publication number: 20190022934
    Abstract: Provided are a manufacturing apparatus and method for a three-dimensional object, and a material supply unit to be used in the manufacturing apparatus for a three-dimensional object which make it possible to obtain an intended three-dimensional object formed by accumulating a shaping material and to hardly form an unnecessary portion on the surface of the three-dimensional object. A nozzle part (4) for ejecting a shaping material (81) is provided with a shut-off pin (5) for opening/closing a channel end part (41) from inside E1. When closing the channel end part (41), a stop position x (mm) of a tip (501) of the shut-off pin (5) with respect to the position of a tip (411) of the channel end part (41) satisfies a relation of ?3D?x?6D wherein an equivalent diameter of the channel end part (41) of the nozzle part 4 is represented as D (mm).
