A magnetic disk substrate includes an aluminum alloy including one type or two or more types of Fe: 8.5 mass % or less, Mn: 2.5 mass % or less, Ni: 6.5 mass % or less, and Mg: 4.5 mass % or less, a balance being Al and unavoidable impurities, wherein, when f (Hz) is a resonance frequency, ρ (g/cm.sup.3) is a density, and t (mm) is a plate thickness, (f×ρ/t) is 3800 or greater; and a magnetic disk using the magnetic disk substrate.

A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.

A method for manufacturing a synthetic non-perforated drainable material is disclosed herein. Generally, the method includes injecting a coating material with air, applying the air-injected coating material to the first side of the material, and curing the air-injected material such that it adheres. Once cured, the material has a highly efficient drainage rate that remains consistent throughout the life of the material.

To improve the visibility of an image displayed on a display from the inside of a vehicle, in a vehicle window glass having the display.

The vehicle window glass has a glass member and a display mounted on said glass member, wherein the visible light transmittance T [%] of said vehicle window glass at the portion including said display and the luminance L [cd/m.sup.2] of the display satisfy T≤0.1×L.

Provided is a protective playmat comprising a first layer of natural rubber foam or neoprene foam or both, the first layer having a first layer top surface and a non-slip first layer bottom surface opposite said first layer top surface; a second layer comprising a second layer top surface and a second layer bottom surface opposite said second layer top surface, the second layer bottom surface being laminated to the first layer top surface, the second layer including a textured polyester cloth blend of between 150gsm and 250gsm; and a third layer comprising a third layer top surface and a third layer bottom surface opposite said third layer top surface, the third layer bottom surface being laminated to the second layer top surface, the third layer including an electrochemical aluminum foil on PET film forming silver dots or holographic dots or both.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

A display panel and a display device are disclosed and include a first non-bending region and a second non-bending region disposed opposite to each other, a support structure disposed between the first non-bending region and the second non-bending region, and a bending region connected to the first non-bending region and the second non-bending region. A step structure is formed on a side of the support structure near the bending region such that when the bending region is squeezed by an external force, the step structure on the support structure can disperse stress, and the bending region would not deform extremely easily, which prevents broken wires and improve a production rate.

Provided is a laminate that is useful as a temporary support for producing a large-area, high-definition, flexible electronic device, the laminate having stably low adhesive strength between a heat-resistant polymer film and an inorganic substrate even in the case of a large surface area, and having few blister defects. This laminate has an inorganic substrate, a silane coupling agent layer that includes amino groups, and a heat-resistant polymer film in the stated order, the laminate being characterized in that the elemental nitrogen component ratio in an inorganic-substrate-side peel surface after the heat-resistant polymer film has been peeled from the inorganic substrate at 90° is greater than 3.5 at % and no greater than 11 at %.

An improved personal flotation apparatus is presented. The personal flotation apparatus is a form-fitting body swimsuit garment having a plurality of uniformly sized and uniformly spaced cells configured to receive uniformly sized flotation material to enable a wearer to float while wearing the device.

A side rail assembly and a mattress assembly including the side rail assembly about at least a portion of a perimeter of the mattress assembly. The side rail assembly includes a laminate structure including one or more foam layers and one or more fiber layers in a stacked arrangement. The fiber layer can be a non-woven layer.
