Abstract: A filament winding apparatus includes a rail extending in a first direction, a core material support device that supports a core material, and a winding device that winds a fiber bundle onto an outer peripheral surface of the core material, the winding device including: a guide unit having an opening through which the core material passes, and guiding the fiber bundle; and a main frame on which the guide unit is mounted; wherein the main frame is movable relative to the core material in the first direction, the main frame is movable in a second direction orthogonal to the first direction, and the main frame is rotatable around a first rotational axis extending in a third direction orthogonal to each of the first direction and the second direction.

Abstract: A filament winding device includes a fiber bundle retainer that temporarily retains fiber bundles. The fiber bundle retainer includes: a reel member including an outer peripheral portion having pins movable in the axial direction relative to the fiber bundles supplied through fiber bundle guides and rotatable about the axis of the liner, the reel member capable of winding the fiber bundles onto the outer peripheral portion; a first cutting unit configured to cut a part of each of the fiber bundles in the circumferential direction, the part being between a part of the fiber bundle wound on the outer peripheral portion and a part of the fiber bundle wound on the liner; and a second cutting unit different from the first cutting unit and configured to cut a part of each of the fiber bundles in the axial direction, the part being wound on the outer peripheral portion.

Abstract: A pedometer which has a walking sensor for detecting a walking by the vibration of a walker's body, a counter for counting the number of walker's walking steps from the walking sensor, an indicator for indicating the value of the counter, a walking reference signal setter for storing a walking reference signal arbitrarily set in advance by the walker, a walking reference signal generator for generating a walking reference signal set by the walking reference signal setter, and sound producing unit for producing a sound upon reception of the output of the walking reference signal generator. Thus, the pedometer can measure a walking reference signal arbitrarily set in advance by a user or a pitch of user's walking when he actually walks with the pedometer by sounding the result as the walking reference signal to give the standard of the strength of his walking motion to the user, thereby providing the walking motion with high motion efficiency.
