Abstract: A constant-voltage circuit includes a transistor (Q3) for output control connected between a source potential and a ground potential and a divider circuit (R1, R2, D2, D3) which are connected in series. The dividing point of the divider circuit connected between the emitter of the transistor (Q3) and the ground potential serves as an output terminal to be supplied with a predetermined voltage by the emitter of the transistor (Q3), so that a constant voltage appears at the output terminal. Connection between the base and the collector of the transistor (Q3) is so improved that the emitter voltage is not changed following a change in the source voltage. More specifically, the transistor (Q3) is connected in such a manner that the collector-to-emitter voltage is continuously clamped by the base-to-emitter voltage of the transistor (Q3), so that the transistor (Q3) is not subjected to a base width modulation effect and thus the emitter potential is not changed following the change in the source voltage.

Abstract: A three dimensional regular polyhedron based logical puzzle having a plurality of exposed faces with design indicia printed thereon includes a plurality of first and second pieces defined by at least four non-orthogonal planes extending through the puzzle. Each of the planes is parallel to at least a different one of the faces and extends through the geometric center of the puzzle to form the first pieces contiguous with an associated group of second pieces to define a cluster formed outwardly from a corresponding bisecting plane. The cluster is capable of rotational movement about non-orthogonal axes extending through the first pieces. Rotation of the clusters causes the second pieces to interchange positions with each other to locate exposed surfaces of the pieces on different faces of the polyhedron to achieve a desired design pattern solution thereon.
