Abstract: An internal combustion engine ignition device comprises an ignition coil, a preliminary assembly, and a casing for accommodating and covering the ignition coil and the preliminary assembly with resin. The preliminary assembly comprises a heat sink, a control unit, and a cushion cover for covering the heat sink and control unit and having at least one first protrusion. The control unit comprises a control circuit for controlling the flow of primary current in the ignition coil, and at least one first recess for engaging with the first protrusion of the cushion cover.
Abstract: An operation mode is first selected in which tunes recorded in a digital audio disk are sequentially reproduced. Reproduction-undesired tunes are selected by operating a manipulator for stopping reproduction of a currently reproduced tune and starting the next tune during every reproduction of the reproduction-undesired tunes so that their numbers are stored in a memory. In subsequent reproductions, the number of each tune going to be reproduced is compared with the numbers of the reproduction-undesired tunes stored in the memory and the tune is skipped if its number is included in the stored numbers.
