Abstract: In an electrochemical device of an embodiment, a cell stack has a spacer disposed to be arranged next to an insulating sealing member in a direction orthogonal to a stack direction. A plurality of the spacers are arranged in the stack direction between a pair of end plates, and the spacer is interposed between a pair of separators adjacently arranged in the stack direction. The spacer is formed of a material whose thickness reduction ratio when an operation of the electrochemical device is executed is smaller than that of the insulating sealing member. Before the execution of the operation of the electrochemical device, the thickness of the spacer is thinner than the thickness of the insulating sealing member. Further, the thickness of the spacer keeps a state of being equal to or less than the thickness of the insulating sealing member when the operation of the electrochemical device is executed.

Abstract: An interconnector for a solid oxide electrochemical cell stack of at least one embodiment includes a metal base that contains an iron-base alloy containing chromium, a protective film provided on a surface of the metal base, and an interlayer provided between the metal base and the protective film arranged to relieve stress.

Abstract: A display device includes a display panel and a reinforcement body. The display panel includes in at least a part thereof a flexible section that is flexible. The reinforcement body is attached to the flexible section. The reinforcement body includes a reinforcement main body, a dispersion medium, a plurality of particles, and an aggregation section. The reinforcement main body has an accommodation space overlapping the flexible section. The reinforcement main body is flexible. The dispersion medium is contained in the accommodation space. The plurality of particles are dispersed in the dispersion medium. The aggregation section aggregates the plurality of particles so as to form an aggregation layer in the accommodation space.

Abstract: A display device includes an active matrix substrate; a light-emitting element layer including a plurality of first electrodes, a function layer, and a second electrode; and a sealing layer. The light-emitting element layer further includes an edge cover layer configured to cover an end portion of each one of the plurality of first electrodes. The edge cover layer includes a plurality of openings configured to expose the plurality of first electrodes included in a plurality of pixels. The plurality of openings include a first opening with a rectangular shape. A first individual vapor deposition film with a rectangular shape is formed on the first electrode covering the first opening. In the first individual vapor deposition film, projection portions projecting from sections corresponding to at least some opposing vertices of the first opening to an opposite side to the first opening are provided on the edge cover layer.

Abstract: Provided is a measuring device configured to measure an outer shape of a metal plate containing a magnetic body. The measuring device includes a stage on a front face of which the metal plate is set, a light source configured to radiate light toward the stage, an image acquisition unit configured to acquire an image of the metal plate, a plurality of magnetic force generation units configured to generate magnetic force on a back face side of the stage, and a controller configured to control positions at which the magnetic force is generated.

Abstract: The present invention is concerned with improved means for etching circuit structures on printed circuit board or wafer substrates of copper or copper alloys in a manner effectively removing unwanted copper from such circuit structures leaving behind a smooth copper surface applying an etching solution containing an Fe(II)/Fe(III) redox system and sulfur containing organic additives. It is an advantage of the present invention that the solution can also applied for plating of copper prior to etching.
