Abstract: A battery includes an electrode collector, two electrode active material layers, two solid electrolyte layers, two counter-electrode active material layers, and two counter-electrode collectors in this order, and includes a first insulating layer that covers side surfaces of the two counter-electrode collectors, the two counter-electrode active material layers, the two solid electrolyte layers, and the two electrode active material layers. A first region not covered with any of the two electrode active material layers is provided at ends of both principal surfaces of the electrode collector. A second region not covered with any of the two counter-electrode collectors is provided at an end of a principal surface of each of the two counter-electrode active material layers that faces toward a corresponding one of the counter-electrode collectors. The first insulating layer covers the second region. The electrode collector projects from an outer surface of the first insulating layer.

Abstract: A battery includes: a power generation element including battery cells each of which includes an electrode layer, a counter-electrode layer, and a solid electrolyte layer located between the electrode layer and the counter-electrode layer, and which are electrically connected in parallel and stacked; an insulating member covering an electrode layer at a side surface of the power generation element; and a terminal electrode covering the side surface and the insulating member, and electrically connected to a counter-electrode layer, in which the power generation element includes: a first parallel unit that includes first battery cells and has both ends in a stacking direction at each of which a counter-electrode layer is located; and a second parallel unit that includes second battery cells, has both ends in the stacking direction at each of which an electrode layers is located, and is stacked on the first parallel unit.

Abstract: A battery includes battery cells. A battery cell includes a positive electrode active material layer, a negative electrode active material layer, and a solid electrolyte layer disposed between the positive electrode active material layer and the negative electrode active material layer. On a side surface of the battery cell, in a plan view of the side surface of the battery cell, striated cut marks which are inclined with respect to the thickness direction of the battery cell are provided.

Abstract: In a governor device of a diesel engine, a control rack of a fuel injection pump is adapted to be controllably actuated by a balance between a governor spring and an engine revolution speed responsive means. A speed control member is adapted to be manipulated for adjusting a tension force of the governor spring. A fuel limiting actuation member serves to prevent an excessive fuel flow from being injected when the speed control member is manipulated for a quick acceleration. A quick acceleration state detecting means serves to detect a quickly accelerated state of the engine so as to selectively change over the fuel limiting actuation member to a fuel limiting position and to a fuel limitation cancelling position depending on the lapse of time.
