Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of β stabilizer elements to the surface and melting and resolidifying the surface. An average value of β stabilizer element(s) concentration in a range of within 1 mm in depth is higher than β stabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the β stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.

Layered, and optionally dispersible fibrous structures containing fibrous elements that exhibit inter-layer voids between two or more layers within the fibrous structures, sanitary tissue products employing such layered, optionally dispersible fibrous structures, and methods for making same are provided.

The present invention relates to a polyvinyl acetal resin film, comprising a polyvinyl acetal resin material, wherein at least one surface has a relative diffuse reflectance of 3% or higher at a wavelength of 550 nm, an absolute difference between the relative diffuse reflectance of one surface at a wavelength of 550 nm and that of the other surface at a wavelength of 550 nm is 0.5% or larger, and the amount of a plasticizer in the polyvinyl acetal resin film is 0 to 20% by mass based on a total mass of the polyvinyl acetal resin film.

According to the present invention, provided are a molded article formed of a thermoplastic resin composition, the molded article having a mean deviation of surface frictional coefficient of 0.02 or more and 0.08 or less, a mean deviation of surface roughness of 4 μm or more and 12 μm or less, a work of compression of 0.05 gf.Math.cm/cm.sup.2 or more and 0.30 gf.Math.cm/cm.sup.2 or less, a bulk density of 0.20 g/cm.sup.3 or more and 0.70 g/cm.sup.3 or less, an area ratio of through-holes of less than 3%, and a thickness of 10 μm or more and 1000 μm or less, and a laminate having the molded article.

The invention relates to a structured body and a method for its preparation, whereby the structured body is produced of at least one powdery starting material by application of heat and/or pressure, and has several layers, whereby the starting material consists predominantly of thermoplastic basic material, and whereby the density of at least two layers of the structured body differ from each other, and whereby at least one layer of lower density contains hollow microspheres.

A treat-insulation material, includes: a first substrate layer that includes an aerogel and first fibers; and a second substrate layer that is layered on the first substrate layer and that includes an aerogel and second fibers, wherein a volume density of the aerogel in the first substrate layer is larger than a volume density of the aerogel in the second substrate layer, and an amount of the aerogel that is present around a first surface of the second substrate layer inside the second substrate layer, not adjacent to the first substrate layer, is smaller than an amount of the aerogel that is present around a second surface (inside the second substrate layer adjacent to the first substrate layer.

A sheet includes a first surface, a second surface, an adhesive portion, a fold-back portion, and a first area. The first surface extends in a first direction. The second surface is opposite to the first surface, and allows light to pass therethrough from the first surface to the second surface. The adhesive portion is a portion of the first surface to which an adhesive is applied, and is disposed at a first end portion of the sheet in the first direction. The fold-back portion is disposed on the first end portion. The first area is disposed on the adhesive portion between a first edge of the first end portion and the fold-back portion.

Provided are assemblies, each including a first structure having a uniform coefficient of thermal expansion (CTE) and a second composite structure having a variable CTE. Also provided are methods of forming such assemblies. The second structure has overlap, transition, and baseline regions. The overlap region directly interfaces the first structure and has a CTE comparable to that of the first structure. The baseline region is away from the first structure and has a different CTE. Each of these CTEs may be uniform in its respective region. The transition region may interconnect the baseline and overlap regions and may have gradual CTE change from one end to the other. The CTE variation with the second composite structure may be achieved by changing fiber angles in at least one ply extending through all three regions. For example, any of the plies may be subjected to fiber steering.
