    • The present invention is characterized in that in a metal-core multilayer printed wiring board (1) which is obtained by forming one or more of at least inner layers of a laminate having a insulating layer and a conductor layer stacked alternately from a metal plate and has the metal plate as a core, the metal plate (13) is disposed below a site on which a heating element (10) is to be mounted, a surface layer over which the heating element (10) is to be mounted is connected to the metal plate (13) of the inner layer via a BVH (12) and a heat radiation layer (14) is formed over the surface layer. The present invention makes it possible to efficiently radiate heat, which has been released from the heating element, to the outside of the printed wiring board without impairing the packaging density of circuits and at the same time, to mount another element on the side opposite to the side on which the heating element exists.

    • A serial printer comprising a print wheel having numerous type bearing spokes, each of which extends radially and which is provided with a type element on the tip of the spoke, a stepping motor for rotating the print wheel, a print hammer for striking the desired spoke behind the type element during printing operation, a positioning means for guiding a selected type element to a printing point during the striking operation of the print hammer, and a control circuit for regulating the driving of the stepping motor and the print hammer. The control circuit causes the stepping motor to move the selected type element to a position whereat the type element is struck by the print hammer. The control circuit suspends the energize-hold operation of the stepping motor at the moment that the type element is struck by the print hammer. This invention accurately positions the type element for substantially aligned printing operation, and greatly reduces damage to the spokes due to material fatigue.
