    • An optical element of the invention comprises at least three laminated circular-polarization-type-reflection polarizers (a) whose wavelength bands for selective reflection of polarized light overlap one another; a layer (b1) which is placed between at least a pair of the circular-polarization-type-reflection polarizers (a) and has a front retardation of substantially zero (in the normal direction) and a retardation of at least λ/8 with respect to incident light inclined by at least 30° relative to the normal direction; and a layer (b2) which is placed between at least another pair of the circular-polarization-type-reflection polarizers (a) and has a front retardation of substantially zero (in the normal direction) and a retardation of at most λ/2 with respect to incident light inclined by 60° relative to the normal direction. The optical element condenses or collimates incident light from a light source and can control transmission of light at large incident angles relative to the normal direction, increase front brightness and reduce coloration.

    • Cell-to-cell connection plates (1) each integrally having a welding part (2) shaped to fall within a circular end of a battery case (7) and a connecting part (2) extending from this welding part (2) are provided. The cell-to-cell connection plates (1) are attached to one electrode terminal and the other electrode terminal of the battery case (7) by welding the welding parts (2), respectively. The connecting parts (3) of the respective cell-to-cell connection plates (1) attached to each adjoining pair of cylindrical batteries (Ba) are overlapped with each other and coupled into electric connection. Consequently, regardless of whether a plurality of cylindrical batteries (Ba) are axially arranged in series or radially juxtaposed, each adjoining two can be connected to each other by using the identical cell-to-cell connection plates (1) for cost reduction. It is also possible to provide a sufficient heat dissipation effect and achieve sufficient robustness and weight saving even when connecting large-sized cylindrical batteries.
    • 提供一体地具有成形为落入电池壳体(7)的圆形端部的焊接部分(2)和从该焊接部分(2)延伸的连接部分(2)的电池至电池连接板(1) 。 电池单电池连接板(1)分别通过焊接焊接部件(2)附接到电池壳体(7)的一个电极端子和另一个电极端子。 安装在每个邻接的一对圆柱形电池(Ba)上的各个电池单电池连接板(1)的连接部分(3)彼此重叠并且电连接。 因此,无论多个圆柱形电池(Ba)是串联还是并排排列,每个相邻的两个可以通过使用相同的电池单电池连接板(1)相互连接,以降低成本。 即使连接大尺寸的圆柱形电池,也可以提供足够的散热效果并实现足够的鲁棒性和重量节省。
