Abstract: A vibratory plate includes a first layer (3) containing a fiber material and having a first surface and a second surface opposing the first surface, a second layer (2) containing a sliced natural wood in the form of a single sheet having a thickness less than 140 ?m, the second layer having a third surface arranged on the second surface and a fourth surface opposing the third surface, and a resin part (4) provided in the first layer (3) and the second layer (2) to join the first layer (3) and the second layer (2) adhesively. The resin part (4) is arranged in the second layer (3) so that a fill ration of the resin part on the fourth surface gets smaller than a fill ration of the resin part on the third surface.

Abstract: An electroacoustic transducer includes a magnetic circuit; a frame enclosing the magnetic circuit; and a diaphragm including a center vibrating portion and an outer circumferential vibrating portion, the diaphragm comprising: a first plate thickness area including an entirety of the center vibrating portion, having a double-layer structure of a wood sheet and a reinforcement sheet; and a second plate thickness area including the edge portion of the outer circumferential vibrating portion, having a plate thickness thinner than a thickness of the first plate thickness area, and having a single-layer structure of the reinforcement sheet.

Abstract: An organic electroluminescence element is composed of a plurality of first electrodes 18 that are disposed on a substrate 14 in matrix, a second electrode 26 that is disposed with being confronted with each of the plurality of first electrodes 18 and a emissive layer formed between each of the plurality of first electrodes and the second electrode on each of the plurality of first electrodes, wherein the emissive layer is composed of a blue (B) emissive layer, a green (G) emissive layer and a red (R) emissive layer as a set of pixels, the organic electroluminescence element is further characterized in that the B emissive layer contains a B emissive material, the G emissive layer contains B and G emissive materials, and the R emissive layer contains B and G and R emissive materials. Accordingly, the organic electroluminescence element is small in size and high in definition, performance and productivity.

Abstract: A magnetic recording medium has a substrate and a magnetic layer formed on the substrate. The magnetic layer includes magnetic powder and a binder for binding the magnetic powder on the substrate. The binder includes at least a resin component containing at least an aminoquinone structure selected from an aminoquinone structure group shown with formulas (1-1a), (1-1b), (1-3a) and (1-3b) as a constitutional unit and at least a polar group selected from a group shown with a formula (1-2) in a composition of the resin component. Thus, the magnetic recording medium has excellent corrosion resistance of the magnetic powder and excellent conservation and running durability.
