Abstract: A display having high resistance to counterfeiting is provided. A display (1) includes a micro concavo-convex structure layer (4) on a predetermined reference surface (H), the micro concavo-convex structure layer (4) having a plurality of microstructures (4A) arranged on the reference surface (H). Each of the microstructures (4A) is formed of a prism structure made of a material that transmits light with a triangular cross-section having a first surface (4Aa) inclined relative to the reference surface (H) in side view, and a second surface (4Ab) having an inclination angle relative to the reference surface (H) such that the inclination angle is larger than an inclination angle of the first surface (4Aa) relative to the reference surface. A color layer 7 as an example of a functional layer is provided on the second surface (4Ab) of all or some of the plurality of microstructures (4A).

Abstract: A light control unit includes a light control sheet and a buffer member. The light control sheet includes a pair of transparent conductive layers and a light control layer that is located between the pair of transparent conductive layers and that contains a liquid crystal composition. The light control sheet is bonded to a surface of a transparent plate having an edge that is held in a window frame. The buffer member has a harder and thicker portion than the light control sheet. The buffer member is located outside an edge of the light control sheet at the edge of the transparent plate on the surface.

Abstract: There is provided an electrode catalyst layer that is greatly improved in power generation performance under low-humidity conditions and high-humidity conditions, a membrane-electrode assembly including the electrode catalyst layer, and a method for producing the electrode catalyst layer. The electrode catalyst layer according to the present embodiment has platinum particles as a catalyst, further includes carbon particles, fibrous substances, and polymer electrolyte, and is a single layer. The electrode catalyst layer satisfies the following equation (1) where D/W represents the ratio of a thickness D and a platinum support amount W of the electrode catalyst layer, C represents the ratio of mass of the carbon particles to mass of the electrode catalyst layer, and F represents a ratio of mass of the fibrous substances to the mass of the electrode catalyst layer. 6.0 > C + F ⋅ D / W ≥ 1.0 cm 3 / g

Abstract: Provided is an ultrasonic sealing anvil capable of applying more uniform sealing pressure in a sealing direction. The ultrasonic sealing anvil has a strip-shaped pressing surface (10) that faces a vibration applying surface of an end of a horn and extends along a welding position of sheet members, the pressing surface (10) having a step (10A) and a pair of extending surfaces (10B), the step (10A) having a concave shape formed at a position at which the step abuts a thick layer portion R with a relatively large thickness of the laminated sheet members and having inclined surfaces (10Ab) on both left and right sides, the pair of extending surfaces (10B) being continuous to the respective inclined surfaces (10Ab) on the both left and right sides of the step (10A) and extending leftward and rightward along the welding position with the step (10A) interposed therebetween, wherein the inclined surface (10Ab) has one or more grooves (20) that extend in a width direction of the pressing surface (10).
