Abstract: A mark unit includes a holding section that is disposed at the top of a display section so that a light-emitting section is positioned on a side of a display screen of the display section and a weight section is positioned on a side opposite to the display screen to hold the light-emitting section on the side of the display screen that intersects a horizontal plane.

Abstract: The agent basically consists of Saxolith, a crystalline marble-based filler, and Erkamar, a binder having adhesive properties. The agent preferably also contains dimethylethanolamine to improve the dissolution of resins and to stabilize the pH, as well as isopropanol as the diluent, Sipernat to improve the flow properties, Agitan as defoaming agent and coagulant, as well as Byk to improve the flow properties and as a filler. The agent is produced by adding Erkamar to at least the same quantity of water, mixing it and stirring it for a few hours, cooling the mixture to room temperature, and adding at least the same quantity of Saxolith as that of Erkamar added previously and stirring until a homogeneous mixture is obtained.

Abstract: A game system that uses a swinging launcher to strike and propel a magnetic projectile. The magnetic projectile is propelled toward a primary target. If struck, the magnetic projectile clings to the primary target with magnetic attraction. Optional obstacles may be provided to make the striking of the primary target more difficult and the game more challenging. A tee is provided for placement of the magnetic projectile. The swinging launcher is spring loaded. The swinging launcher has a striking head that contacts the magnetic projectile on the tee when the spring loaded striking head is cocked and released. The striking head hits and separates the magnetic projectile from the tee thereby propelling the magnetic projectile toward the target.

Abstract: A fishing game is played with a rod, a reel, and line. A holder is connected to the end of the line and an engaging fabric marker is removably attached to the holder. The holder and marker are cast at a target having an engaging fabric surface. If the marker lands on the target, it remains engaged to the target and separates from the holder when the line is retrieved.

Abstract: A dart board includes a plurality of target blocks engaged with spaces defined by ridges. Each target block has a plurality of posts extending therefrom. Each post has at least one recess defined in a periphery thereof. A dart hole is defined in the target block and located beside the posts. A receiving member is connected to an underside of the target block. The dart tip is guided by the posts and successfully inserted into the dart hole. The dart tip is then firmly attached to the receiving member.
