Disclosed are a protective coating composition for an electronic board and a method for preparing the same. The protective coating composition includes urethane-modified alkyd resins that can prevent poor grounding caused by low molecular weight siloxanes generated in a conventional silicone-type coating compositions and preventing performance degradation caused by tin whisker growth while lowering emissions of volatile organic compounds (VOCs).

A prefabricated tuned top and a launcher for launching the tuned top, manufactured in a small size with five components of a knob, a rim, beads, a body and a spinning spindle. The tuned top can be readily assembled by sequentially inserting and then tightening the components. The tuned top implements a changeable spinning form based on induction of a change in difference between the centripetal force and centrifugal force, generated during spinning, since the center of gravity can be eccentrically disposed freely according to the user's selection. The tuned top is prevented from being reversely loosened so it can be safely, semi-permanently, and easily enjoyable at any location. The tuned top enables accurate and stable mounting when a launcher is used, such that the top is not easily separated therefrom but is quickly launched without a launch failure, thereby providing accurate launching without the loss of spinning power.

The present invention relates to a framed dartboard in which a magnetic rubber pad is combined with a case member of a picture frame that can provide interior decorations for the dartboard. The framed dartboard comprises a case member forming an outer case of the framed dartboard, a printed plate at least partially enclosed within the case member and containing designs related to a dart game, a magnetic rubber pad disposed at a rear side of the printed plate for attaching a magnetic dart, an elastic member disposed at a rear side of the magnetic rubber pad to absorb an impact force by the magnetic dart, a back plate which is disposed at a rear side of the elastic member, and a hanger portion for attaching the framed dartboard to a suitable external structure.

The present invention relates to a dart board assembly which makes a front dart board positioned on a rear board rotate smoothly while preventing separation due to the vibration from rotation of the front dart board. The front dart board includes a flat panel; a central shaft rearwardly protruding at the center of the flat panel, an inner stepped portion stepped at the inner diameter of the central shaft to a predetermined depth, and an engaging recess formed at the center of the central shaft for engaging a screw spike. A connection shaft is formed with a plurality of stepped portions including a proximal stepped portion inserted into the inner stepped portion of the central shaft, an intermediate portion supported by the inner diameter portion of the rear board, a distal stepped portion stepped and coupled to the inner diameter portion of a ball bearing, and a through hole formed at the center so that the screw spike can be passed through.
