The constituents of the tablet are calcium carbonate, fumaric acid and a water soluble third reactant wherein the calcium carbonate and the fumaric acid are present in approximately molar equivalent amounts and the third reactant is present in an amount sufficient to control the effervescence, allowing the tablet to dissolve completely without breaking apart and leaving any appreciable residue. The third reactant is preferably calcium lactate.

Abstract: A multi-layered target is provided in which the shooter's results are permanently recorded and displayed as a work of art. A metallic sheet layer is used in conjunction with a covering layer upon which target dots are imprinted in a desired design or pattern. By successfully shooting the target dots of the covering layer, a shooter records his shot on the underlying metallic sheet layer. A successful round of shooting is reflected in the reproduction on the metallic sheet layer of the artistic design created by the target dots. The metallic sheet layer may be framed and hung as a constant remainder of a shooter's accuracy.

Abstract: A place mat includes a thin, substantially flat rectangular member having opposite surfaces; one of the surfaces serving as an operative surface, and at least one surface of the member being liquid impervious; a tab having indicia thereon, formed on one edge of the member; and a fold line formed in the member to permit folding of the member thereabout into a configuration of a file folder such that the tab extends beyond respective edges of the member. To use the place mat, the member is folded along the fold line to form the place mat into the configuration of the file folder. The folded place mat is then stored in a file cabinet under the indicia, with the tab and indicia thereon being exposed for view in the file cabinet. The place mat is then removed from the file cabinet for use, unfolded along the fold line to provide a substantially flat place mat, and placed on a surface for receiving foodstuffs on the liquid impervious surface.

Abstract: A printed circuit board capable of preventing electromagnetic interference comprises a base plate composed of an insulating material. On the main surface of the base plate, a first electric conductive layer is formed by etching copper foil, which includes a signal electrode portion and a ground electrode portion. On the first electric conductive layer, an insulating layer such as a solder resist film is formed except for a part of the ground electrode portion, and on this layer, a second electric conductive layer is formed by screen-printing a copper ink so as to cover almost all of the first electric conductive layer. A part of the second electric conductive layer is connected to the ground electrode portion of the first electric conductive layer so that the second electric conductive layer acts as an electromagnetic shield. The copper ink is a mixture of copper powder, binder and other materials. A solder layer may be formed on the second electric conductive layer composed of the copper ink.
