Described herein are textured glass-based articles. The textured glass based articles may include a glass-based substrate including a first major surface and a second major surface. At least a portion of one or both of the first major surface and the second major surface is textured, wherein the portion of the one or both of the first major surface and the second major surface that are textured may have a sparkle at 140 ppi of less than or equal to 5% and an uncoupled distinctness-of-image of at least 78%. Methods for making such articles are also described herein.

A glass-based article with a textured surface exhibiting low haze is provided. The glass-based articles are produced by utilizing a combination of abrasion and etching, where hydrofluoric acid is not utilized. The process for producing the glass-based articles also includes an ion exchange process.

A band saw blade includes a body part made into a loop in an endless form at a joint part formed by welding, a blade part formed on one edge side of the body part, a first shot blasted part formed on at least one side plane of the body part, a second shot blasted part formed in a part of the first shot blasted par and visually recognized as a range having a surface state different from a surface state of the first shot blasted part, and an information part that is provided to the second shot blasted part and from which information can be acquired.

The present invention is to provide an antibacterial molded article that can increase options for the material and shape of the molded article, and a method for manufacturing the same. The object is achieved by an antibacterial molded article containing a plastic molded article, the plastic molded article having a rough region having an arithmetic average roughness Ra of a roughness curve in accordance with JIS B 0601 (2013) of 0.14 μm or greater and 0.72 μm or less provided on a surface with which bacteria can come into contact.

The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

The present invention improves surface roughness by knocking down protruding parts while leaving recessed parts in the surface of a metal product, protrusions/recesses having been formed in said surface via blasting, and improves surface hardness and compressive residual stress. Treatment is performed upon a metal product in which protrusions/recesses have been formed in the surface thereof via blasting. Spherical shot that are less hard than the surface hardness of the metal product and have a particle size that is greater than the width of recessed parts of the protrusions/recesses are sprayed toward and collide against the surface of the metal product as crushing shot, and the protruding parts of the protrusions/recesses formed on the surface of the metal product are selectively knocked down, thereby providing a metal product surface member in which the surface roughness of the metal product has been improved.

A mesh spray erosion assembly includes a spray board having a length, a width, and a material thickness, a tile blank having a length, a width, and a material thickness supported on one side of the spray board, a mesh frame having a length and width greater than that of the tile blank, and a material thickness equal to or less than that of the tile blank, the mesh frame centered over the tile blank and mounted to the spray board, and a mesh screen having a length and a width, the mesh screen centered over the mesh frame and mounted thereon, the mesh screen including non-masked portions and masked portions, characterized in that a user may apply a pressurized liquid spray through the non-masked portions of the mesh screen against the surface of the tile blank eroding material from the surface thereof according to artist design.

The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.

Disclosed herein is an antiglare glass sheet article for display devices in which at least one main surface of the glass sheet is roughened. The article has a roughened surface that includes: a surface with continuous irregularities having an arithmetic average roughness (Ra) of 0.01 to 0.1 μm, and an average interval (RSm) of 1 to 20 μm; and depressions dispersed over the surface and each having a circular entrance portion measuring 3 to 20 μm in diameter, and a depth of 0.2 to 1.5 μm from the entrance portion, the roughened surface having 60 to 600 of the depressions in an observed 250 μm ×250 μm region. The article has desirable antiglare properties with reduced sparkling.
