Abstract: A method for producing a battery, the method includes a liquid injecting process. In this liquid injecting process includes: a first liquid-injecting step of injecting an electrolytic solution of a first injection amount (V1) determined so that a liquid-level height of the electrolytic solution falls within an intermediate liquid-level range in which the liquid-level height is equal to or higher than a first reference height but is lower than a second reference height while an air pressure in a metal battery case is regulated to a first air pressure; and a second liquid-injecting step of injecting the electrolytic solution in a remaining second injection amount up to a specified amount while increasing the air pressure in the metal battery case to a second air pressure higher than the first air pressure and maintaining the liquid-level height of the electrolytic solution within the intermediate liquid-level range.

Abstract: A method for producing a battery includes discharging bubbles, which stick to an inner surface of an injection nozzle, to outside of an injection nozzle together with an electrolyte ejected from the injection nozzle by ejecting the electrolyte from the injection nozzle under atmospheric pressure before evacuating is performed.

Abstract: A battery case includes a case-penetrating hole. An external terminal includes a member-engaging hole and is stacked on an outside of the battery case so that the member-engaging hole and the case-penetrating hole align with each other. An internal terminal includes a shaft portion and a fastening portion. The shaft portion is inserted through the case-penetrating hole and the member-engaging hole from an interior of the battery. The fastening portion is fastened to a circumferential periphery of the member-engaging hole by crushing a tip end of the shaft portion. The internal terminal is stacked on an inside of the battery case. The fastening portion and the external terminal include a welded portion welded along a weld line set across a periphery of the fastening portion. The welded portion has a length K1 along the weld line and a width K2 along a direction perpendicular to the weld line, and the length K1 is at least 1.5 times longer than the width K2.

Abstract: An open/close adjustment device is connected to the door of a heating chamber of a cooking device, and the open/close adjustment device pulls the door back to its totally closed position. The open/close adjustment device adjusts an operation force when the door is passing a predetermined open angle. The operation force indicates a maximum value when the door is passing the predetermined open angle, and the maximum value is given by two protrusions disposed at front-side and rear-side with distance between them. Each of the protrusions each produces a load when they go over a support member, and a following one of the two protrusions produces a load larger than a load firstly produced by a preceding one of the two protrusions when the door is opened.
