Abstract: The power storage device includes power storage units arranged with a conductive plate interposed therebetween in the vertical direction, each of the power storage units includes an electrode stack including bipolar electrodes stacked with a separator interposed therebetween, and a sealing member provided around the electrode stack so as to seal a housing space formed between adjacent electrodes of the electrode stack. At least one of the power storage units is provided with an overhang member on an outer peripheral surface of the sealing member. The overhang member includes an inclined portion that extends from the outer peripheral surface of the sealing member toward the outside of the power storage unit and inclines downward as it leaves away from the outer peripheral surface of the sealing member, and a top portion formed at a lower end of the inclined portion.

Abstract: A single-tube color television camera is disclosed wherein the optical image of a subject is split into three color images by an optical color filter consisting of first vertical stripes for transmitting therethrough all of the three primary color components, second vertical stripes for transmitting therethrough only two of the primary color components, and third vertical stripes for transmitting therethrough only one of the two primary color components, the first, second and third sets of stripes being arrayed cyclically; the three color images projected on the target of a television camera tube are scanned by the electron beams in the direction at right angles to the stripes of the optical color filter; and the predetermined components of the color video signal outputs from the television camera tube are added or substracted so that the three primary color video signals may be derived.
