  • Patent number: 9522448
    Abstract: A predetermined component such as a recliner is attached to a long member in advance, and thereafter by bending the long member, a pair of side frames and an upper frame are integrally formed. Therefore, the recliner can be attached to the long member not bent yet and thus in a substantially flat state, and in addition, the pair of side frames and the upper frame can be integrally formed, which does not require labor and contributes to a reduction in manufacturing cost. Moreover, by adjusting a position where the bending is performed, it is possible to manufacture seat frame structures different in dimension even if the long members not bent yet have the same length, and from this viewpoint as well, it is possible to reduce labor and manufacturing cost.

  • Patent number: 7400556
    Abstract: An electronic timepiece with a solar cell includes a timepiece movement, a timepiece case for housing the timepiece movement, a casing ring for housing and holding the timepiece movement in the timepiece case, a solar cell and a dial. The solar cell is disposed almost vertically to a solar cell positioning portion provided in the casing ring, and the solar cell has a slender strip shape formed on a flexible substrate. Consequently, the solar cell is not disposed in the timepiece movement, and it is only necessary to change the casing ring as an external component even when a panel cover diameter is changed. Further, a solar cell can be coiled to match the size of the casing ring when it is incorporated in the casing ring, so that a common solar cell can be used despite a change in the panel cover diameter of the timepiece.
