Abstract: A secondary battery negative electrode according to the invention includes: a three-dimensional current collector formed of a self-supporting sponge-like structure of carbon nanotubes; a metal active material contained inside the three-dimensional current collector; and a plurality of seed particles contained inside the three-dimensional current collector and made of a material different from the metal active material, in which the secondary battery negative electrode does not include a foil of the metal active material.

Abstract: An end of a shell forming a high-pressure container is opened to form an opening. A cap is disposed partially inside the opening to close the opening. A shell reinforcing layer having a first reinforcing layer that is made of a first fiber-reinforced resin having a fiber direction oriented in a circumferential direction, and a second reinforcing layer that is integrated with the first reinforcing layer and made of a second fiber-reinforced resin having a fiber direction oriented in an axial direction, is wrapped in layers around an outer circumferential surface of the shell. The second reinforcing layer is placed over a region of the first reinforcing layer.

Abstract: A high-pressure vessel includes a liner, an outer layer, a ferrule, and a seal member. The liner has a cylindrical shape, and is made of a first resin. The outer layer is joined to an outer peripheral surface of the liner, and is made of a second resin having a linear expansion coefficient that is lower than a linear expansion coefficient of the first resin. The ferrule is made of metal, is at least partly disposed radially inward of an inner peripheral surface of the liner, and is configured to provide communication between an internal space of the high-pressure vessel and an outside of the high-pressure vessel. The seal member is disposed between the inner peripheral surface of the liner and the ferrule, and is configured to seal a gap between the inner peripheral surface of the liner and the ferrule.

Abstract: A conduction-breaking device breaks conduction between a pair of devices in an electric circuit. The conduction-breaking device includes a conductive body having a cuttable portion, an arc-extinguishing chamber having a pair of fixed blades, a gas generator, a cutting member having a pair of movable blades, and a deforming mechanism. When the cuttable portion is cut at two positions by the fixed blades and the movable blades, the cuttable portion forms a separated piece, which is separated from the electric circuit, and first and second remaining portions, which remain connected with the electric circuit. The separated piece has cut ends at opposite ends. The deforming mechanism deforms the separated piece such that the cut ends of the separated piece are located on a leading side in a moving direction of the cutting member with respect to a part of the separated piece between the cut ends.

Abstract: A breaker includes conductors, each including an elongated flat cut portion, cutting chambers arranged in correspondence with the cut portions, a single cutting member that includes blades to cut the cut portions in the cutting chambers, a gas generator that generates gas to move the cutting member toward the cut portions, and an arc attenuation portion located between the two cut portions that are adjacent to each other. The conductors are located between two devices. Each cut portion is cut to form two separated cutting ends and electrically disconnect the devices. The arc attenuation portion attenuates an arc generated between the two cutting ends of one of the two adjacent cut portions and the two cutting ends of the other cut portion.

Abstract: The conduction breaking device includes a conductive body, a fixed blade, an arc-extinguishing chamber, a gas generator, a cutting member, and a cutting delaying portion. The fixed blade and the arc-extinguishing chamber are located on one side of the cuttable portion with respect to a thickness direction of the cuttable portion in the conductive body. The gas generator is located on the opposite side of the cuttable portion with respect to the thickness direction. The cutting member is arranged between the cuttable portion and the gas generator and includes a movable blade. The cutting delaying portion is provided at the movable blade and configured to allow a part of an area of the cuttable portion that is, in the width direction, closer to the center than the edges are to the center to be cut after the other parts are cut.

Abstract: A magnetic card in which a magnetic layer is successfully concealed without lowering the magnetic output of the magnetic layer and giving any restriction to the design of the card. Such a magnetic card can be produced in the following manner. A magnetic layer (magnetic stripe) 12 is formed on a substrate 11 by means of thermal transfer, and a thin film layer 13 is formed, by vacuum deposition or the like, on the entire surface of the substrate 11 including the surface of the magnetic layer 12 to conceal the magnetic layer 12. Patterns, etc. are printed on the surface of the thin film layer 13 to form a print layer 14, and a light-diffractive structure layer 15 is further formed on the print layer 14 of thermal transfer. On the other hand, a print layer 14A is provided on the back surface of the substrate 11, and a reverse side protective layer 16 is further provided on the print layer 14A to cover it.
