Abstract: An energy storage apparatus includes: an energy storage device; an electrical component disposed on a path of a current that flows through a main circuit including the energy storage device; a first conductive member including a first connecting portion that is electrically connected to the energy storage device; a second conductive member that is connected to the first conductive member and is electrically connected to the electrical component; and an outer case accommodating the energy storage device, the electrical component, the first conductive member, and the second conductive member, wherein at least one conductive member of the first conductive member and the second conductive member includes: a second connecting portion being a portion that overlaps with an other conductive member and is connected to the other conductive member in a state where the second connecting portion is in contact with the other conductive member; and an extension portion extending from the second connecting portion in a direc

Abstract: A rupture valve is formed on a wall of a container and has a break line along which a wall thickness of the rupture valve is decreased. The break line has an outer edge line which defines an outer edge of an opening region and a plurality of division lines which divide the opening region. The outer edge line has: a first base line and a second base line formed discontinuously such that the first base line and the second base line extend in a first direction, and are formed in a spaced-apart manner in a second direction orthogonal to the first direction; a first support portion forming line formed on a breaking portion of the first base line and extending from the first base line toward the second base line; and a second support portion forming line formed on a breaking portion of the second base line.

Abstract: In a method for producing a de-dimethoxybenzylated compound by removing a dimethoxybenzyl group from a compound containing a dimethoxybenzyl group bonded to a nitrogen atom in the presence of an acid, the de-dimethoxybenzylated compound is obtained by removing the dimethoxybenzyl group without forming a poorly soluble product resulting from the removed dimethoxybenzyl group. The de-dimethoxybenzylation reaction is carried out in the presence of triphenylphosphine or diethylthiourea.
