The locking arm includes a flexible arm main body and an engaging projection portion protruding from an outer surface of the arm main body. The locking protrusion includes a protrusion main body on which an arm guide surface, a protruding tip surface, and an engaging surface are disposed along the engagement direction, and a jig groove that is formed in the protrusion main body. The engaging projection portion is formed on the outer surface at a position away from an arm tip of the arm main body in the engagement direction. The protruding tip surface is longer than the arm tip in the engagement direction. The jig groove cuts out the protrusion main body in the engagement direction from the arm guide surface to the protruding tip surface.

    Abstract: A wire harness arranged in a vehicle has an electrical connection box at the terminal thereof. The electrical connection box includes an electronic component block to which a plurality of electronic components are assembled and a casing to be an assembly destination of the electronic component block. The casing has a structure in which an upper opening portion surrounded by an edge of a frame peripheral wall is rotatably moved and covered by a separate upper cover. In the casing, a protrusion is formed on one of the frame peripheral wall or the upper cover. On the other thereof, a protrusion engaging portion is formed with respect to the protrusion. The protrusion is formed so as to be engaged with the protrusion engaging portion in an inserted state. In such protrusion, a projection is integrally formed so as to at least prevent the upper cover from coming off.

  • Publication number: 20190158839
    Abstract: An encoder includes processing circuitry, a block memory, and a frame memory. The processing circuitry defines at least one parameter for each of plural types of segment_ids, splits an image into blocks, assigns, to each of the blocks, segment_id according to a type of the block, among the plural types of segment_ids, and sequentially encodes the blocks. In encoding the blocks, the processing circuitry identifies segment_id of a current block to be encoded, and encodes the current block using the at least one parameter defined for identified segment_id. The at least one parameter includes seg_context_idx for identifying probability information associated with context used in context-based adaptive binary arithmetic coding (CABAC).
