A bonded abrasive article includes elongate shaped abrasive particles. The elongate shaped abrasive particles comprise an elongate shaped ceramic body having opposed first and second ends joined to each other by at least two longitudinal sidewalls. At least one of the at least two longitudinal sidewalls is concave along its length. At least one of the first and second ends is a fractured surface.

A sampling apparatus is provided, which includes a pressing-up unit configured to press up a sheet piece that is being conveyed by a conveying unit, from a lower side of a conveyance course of the sheet piece to above the conveyance course; and a holding unit configured to hold the sheet piece pressed up by the pressing-up unit.

In a method for manufacturing ceramic substrates and module components, an unfired mother ceramic substrate is cut at predetermined positions for division into separate unfired ceramic substrates. The cut unfired mother ceramic substrate is pressed such that pressure is applied parallel or substantially parallel to its main surfaces so that the cross-sectional end surfaces created in the cutting step are joined. The unfired mother ceramic substrate including end surface junctions, resulting from joining of the cross-sectional end surfaces, is fired. The fired mother ceramic substrate is broken along the end surface junctions to divide it into separate ceramic substrates.

The present invention relates to a method for producing shaped bodies (5) from a building material, in which a layered structure of a shaped body (5) takes place by successively solidifying layers of the building material by exposure to electromagnetic radiation in a layer area having a contour specified for the respective layer. The method provides that together with the shaped body (5), a sleeve-like frame (6) surrounding the shaped body at a distance is constructed layer by layer from the building material, and that in addition, a plurality of pin-like connections (10) are constructed integral with the frame (6) and the shaped body (5), which are distributed around the shaped body (5) and which connect the shaped body (5) with the frame (6).
