  • Patent number: 9915284
    Abstract: A terminal supporting apparatus is provided with: a hub that is attached to an end of the outer cable and is provided with a flange on an outer periphery; a cushion member that is provided to surround the outer periphery of the hub and abuts on the flange at both a front surface and a back surface of the flange; and a housing that houses the cushion member. The cushion member includes a large-diameter portion that abuts on the flange. At least within a range contacting with the hub, at least a part of an outer peripheral surface of the large-diameter portion is fixed to an inner surface of the housing, while a clearance is formed between the cushion member and the inner surface of the housing over an entire region of an end surface of the large-diameter portion in a cable axis direction.

  • Patent number: 9899112
    Abstract: A structure configuring a ridge filter has line symmetry about a line vertical to a depth direction passing the center of the structure. A small structure obtained in such a way that the structure is divided by this line has a bilaterally asymmetric shape about a center line in an iterative direction, and has a point symmetric shape about an intersection between the center line in the iterative direction and the center line in the depth direction. Thicknesses in the iterative direction of an uppermost stream surface and a lowermost stream surface in the depth direction are equal to each other. The structure is configured so that a thick portion in the iterative direction of the uppermost stream surface and the lowermost stream surface is not present in the depth direction.
