  • Publication number: 20110057646
    Abstract: There is provided a position sensing apparatus when a non-orbital movable truck moves over a spherical surface, a cylindrical surface, or a flat surface, which is capable of position sensing even when, e.g., the non-orbital movable truck circumferentially moves over the spherical surface or the cylindrical surface to be hidden from the position sensing apparatus. A second linear encoder is disposed which includes a wire in a main body thereof to output an amount by which the wire is withdrawn as an encoder value. The tip of the wire of the second linear encoder is fixed to a position at the non-orbital movable truck to which the tip of the wire of a linear encoder is fixed. From an amount by which the wire of the linear encoder is withdrawn and the amount by which the wire of the second linear encoder is withdrawn, the position of the non-orbital movable truck is calculated in a calculation device.

  • Patent number: 5610960
    Abstract: With an arrangement that the axial distance from the upper end of a first opening area to the upper end of the second opening area is equal to the axial distance from the upper end of a first coupling member to the upper end of a second coupling member, when a spring member is moved upwardly relative to round cells, the upper end of the second coupling member comes into contact with the upper end of the second opening area, and the spring members receives upwardly acting forces from fuel elements. The spring member is thereby prevented from inclining with respect to flow of a coolant. Simultaneously, the upper end of the first coupling member contacts the upper end of the first opening area, and the spring member is stably held in a condition where it is aligned with the direction of the coolant flow.
