    • A battery container and a battery and a layer-built battery using the container. The battery container can prevent the characteristic deterioration of the battery, in which cells are laminated upon another, caused by accumulated heat or temperature rises in the battery by solving such a problem that the internal temperatures of the cells rise due to the accumulation of the heat generated when the cells are charged or discharged and the temperature rises deteriorate the electricity storing elements of the cells or lower the performances and shorten the service lives of the elements. The battery container has a thick wall section on the outer edge of the wall constituting the container and a thin wall section being thinner than the thick wall section in the area surrounded by the thick wall section. In addition, since spacers composed of liner ribs or grid-like ribs and projections, cylindrical projections, etc., are arranged on the external surface of the thin wall section surrounded by the thick wall section and the external surfaces of the spacers are extended outward from the external surface of the thick wall section, the rigidity and durability of the container are improved and cooling air can be made to flow efficiently to the outer periphery of the container. Therefore, the container can easily transmit the heat in the battery to the outside, because the wall surface of the container can excellently radiate heat to the outside as compared with the conventional battery container, and can extremely improve the performance and service life of the battery.

    • Processing is started (S1), and control of each mounting processing is sequentially executed under a mounting program command in a storage section (S2). An electronic component is positioned on a mounting head, then taken out and held (S3). A BGA component is positioned by position detection of a reference mark and inspection, and correction is carried out in response to discrimination of holding attitude. In inspection using the reference mark as a reference position, the quality of the component is discriminated, for example, loss and shift of a solder bump and insufficiency of the quantity of the solder (S4). A normal component is moved to the vicinity of a mounting position on a printed board on a mounting table by the mounting head (S5). A recognition mark at the target mounting position on the printed board is confirmed and recognized (S6). The mounting position is corrected by mounting positioning based on the results of mounting position detection and component inspection (S7). The height of the mounting head is controlled and the component is mounted (S8). In response to the presence or absence of a mounting component, the processing shifts to processing S1 for continuation of processing, or shifts to processing S10 for end (S9) and the processing ends (S10).
