Abstract: A battery case of a rectangular battery has a main body member that has the shape of a bottomed rectangular tube, and a lid member that has the shape of a rectangular plate. The main body member has a rectangular opening portion that is constituted of opening long side portions, opening short side portions, and opening R portions. The lid member seals the opening portion. The opening portion is configured such that each thickness of the opening R portions is larger than each thickness of the opening long side portions respectively. In addition, the opening portion and a lid peripheral edge portion are welded to each other in an airtight manner along an entire circumference thereof, by an energy beam that is radiated from outside the lid member in a thickness direction thereof.

Abstract: This battery is provided with a power generating element, a battery case main body, a battery case lid, an electrode terminal member which is connected electrically to the power generating element inside of the battery case body and which extends outside of the battery case lid, and an outer insulation member which is arranged on the battery case lid and insulates the electrode terminal member from the battery case lid. The battery case lid is fitted inside of the opening and welded to the battery case main body by irradiating a laser from above the battery case lid towards the boundary section between the battery case lid and the battery case main body. Furthermore, this battery is provided with a plume control portion which prevents the plume that rises from the boundary portion during welding from rising towards the outer insulating member.

Abstract: A liquid jet apparatus comprises a liquid jet head, a carriage carrying the liquid jet head in a side-to-side direction, a liquid flow channel, and a liquid container in fluid communication with the liquid jet head through the liquid flow channel. The liquid container includes a liquid containing chamber arranged along a front/back direction orthogonal to the side-to-side direction; a liquid outlet port, from which the liquid contained in the liquid containing chamber flows to the liquid flow channel; and a liquid inlet port, through which the liquid is injected into the liquid containing chamber. The liquid inlet port has an end surface that does not face in a vertical direction relative to a normal posture of the apparatus.

Abstract: A battery includes an external terminal member and an insulating member on an outer surface of a lid member so that an interval between the insulating member and the lid member is smaller in a long side of the lid member than in a short side. A weld mark is formed over the entire circumference of the lid member to extend across the outer surface of the lid member and an open end face of the case body. The weld mark not only extends across the outer surface of the lid member and the open end face of the case body but also reaches an outer side surface of the case body in a zone of the long side of the lid member facing the insulating member, but does not reach the outer side surface of the case body in a zone except the former zone.

Abstract: A battery houses an electrode body inside a battery case including a bottomed cylindrical case body having an opening part, and a plate-like lid member inserted in the opening part so as to seal the opening. The opening part and a lid peripheral edge part are welded hermetically by an energy beam irradiated from outside in the thickness direction of the lid member. In a specific section, the inner peripheral surface of the opening part and the peripheral edge surface of the lid peripheral edge part are welded in close contact with each other. A bead at the specific section takes a fan shape having a central angle of 160 to 200 degrees in a cross section, and the center of the fan shape is positioned on the inner peripheral surface and the peripheral edge surface.

The liquid container includes a liquid containing chamber arranged along a front/back direction orthogonal to the side-to-side direction; a liquid outlet port, from which the liquid contained in the liquid containing chamber flows to the liquid flow channel; and a liquid inlet port, through which the liquid is injected into the liquid containing chamber. The liquid inlet port has an end surface that does not face in a vertical direction relative to a normal posture of the apparatus.

Abstract: A liquid container includes an ink chamber containing an ink to be supplied via a tube to a liquid ejecting head consuming the ink; an outlet port from which the ink contained in the ink chamber flows to the tube side; an injection port through which the ink can be injected into the ink chamber; and an air intake port taking air into the ink chamber from a further vertically upper position than a liquid level of the ink when the ink is contained in the ink chamber. If the ink equal to 5% of containing capacity containable in the ink chamber flows from the outlet port, the liquid container has an area where a fluctuation range of the liquid level of the ink inside the ink chamber becomes 5% or less of the cubic root of the containing capacity.

Abstract: When an ink film between an outer cap and a nozzle face is broken, an ink film formed between an inner cap and the nozzle face is not broken for the following reason. That is, when the ink film between the outer cap and the nozzle face is broken, a negative pressure is not generated on a space formed by the inner cap because the ink film between the inner cap and the nozzle face is formed to be thick and the space communicates with the outside environment by cutouts. Therefore, the ink film formed on the inner cap is not broken at a time when the ink film formed on the outer cap is broken to the inner side with a negative pressure. This makes it possible to suppress splashing droplets from traveling to nozzle rows.
