    摘要： A fiber placement device that includes a placement surface on which a reinforcing fiber tow is placed and stacked; a tow arranging mechanism which presses and places the reinforcing fiber tow against and on the placement surface; and a heating mechanism which is configured to heat the placement surface. In one placement cycle, the tow arranging mechanism presses a group of the reinforcing fiber tows against the placement surface heated in advance by the heating mechanism, moves by a predetermined length in a first axial direction to glue and fix the group of the reinforcing fiber tows onto the placement surface, and move the placement surface in a second axial direction which substantially intersects the first axial direction.

    摘要： A fiber placement device that includes a placement plane on which a reinforcing fiber tow is placed and stacked; a tow arranging mechanism which presses and places the reinforcing fiber tow against and on the placement plane; and a heating mechanism which is configured to heat the placement plane. In one placement cycle, the tow arranging mechanism presses a group of the reinforcing fiber tows against the placement plane heated in advance by the heating mechanism, moves by a predetermined length in a first axial direction to glue and fix the group of the reinforcing fiber tows onto the placement plane, and move the placement plane in a second axial direction which substantially intersects the first axial direction.

    摘要： The present invention aims to provide a sheet-shaped reinforcing fiber substrate having shear deformability to conform to a three dimensional shape and restraining the generation of waste pieces to realize a large improve in the yield of reinforcing fibers and a reduction in production cost, and also provide a production method therefor.
    The sheet-shaped reinforcing fiber substrate has a layered structure containing N layers (N being an integer of 3 or more) produced by arranging a plurality of reinforcing fiber bundles with appropriate lengths and meets the requirements (1) to (5) given below:



    (1) in each layer, mutually adjacent reinforcing fiber bundles are aligned parallel to each other in such a manner that the clearance between mutually adjacent reinforcing fiber bundles is not smaller than the width of the reinforcing fiber bundles,
    (2) the reinforcing fiber bundles in a layer and those in the layer located immediately above or below and in contact therewith are aligned in different directions,
    (3) the length direction of the reinforcing fiber bundles in a randomly selected odd-numbered no'th layer (no being an odd number not less than 3 and not more than N) and the length direction of the reinforcing fiber bundles in the (no-2)'th layer are parallel to each other and the reinforcing fiber bundles in each layer do not overlap each other,
    (4) in the case where N is 4 or more, the length direction of the reinforcing fiber bundles in a randomly selected even-numbered ne'th layer (ne being an even number not less than 4 and not more than N) and the length direction of the reinforcing fiber bundles in the (ne-2)'th layer are parallel to each other and the reinforcing fiber bundles in each layer do not overlap each other, and
    (5) mutually intersecting reinforcing fiber bundles are joined together in at least part of the intersection regions where a reinforcing fiber bundles in any of the odd-numbered layers directly overlaps a reinforcing fiber bundle in any of the even-numbered layers.

    摘要： A flow channel switching system (1, 1′) including: a first on-off valve (10) which is disposed between a merging portion (6) and a branching portion (5) and in a raw water path (4); a second on-off valve (11) which is disposed in an outward path for raw water (7); and a sensor (13) that measures a state of water flowing through the raw water path, in which control is performed so as to open the second on-off valve and close the first on-off valve if a signal indicating that water is flowing in the raw water path is received from the sensor, then a signal indicating that no water is flowing in the raw water path is received, and then, within a predetermined time period, a signal indicating that water is flowing again in the raw water path is received.

    摘要： A fiber placement device includes an accumulation portion that stores and discharges a reinforcing fiber bundle including: a movable roller guided by a guide mechanism able to be moved in a constant movable range; a cylinder; a piston arranged within the cylinder; a coupling member coupling the movable roller and the piston; and an adjustment portion adjusting a force applied to the piston within the cylinder by discharging fluid from a space with the cylinder sealed on a side opposite the coupling member with respect to the piston within the cylinder or supplying the fluid into the space, the fluid is discharged from the space within the cylinder to apply a force to the piston to move the piston, a force is also applied to the movable roller through the coupling member to move the movable roller and thus a tension is applied to the reinforcing fiber bundle.
