摘要:
The touch-operating input device (1) is configured so that when the control circuit turns on the main light source (11) corresponding to each of the translucent operation buttons (23) that can be operated, the control circuit, on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns off the sub-light source (7) corresponding to the translucent operation button that is turned on simultaneously with the main light source. Ease of operation is increased by enabling the operator to distinguish operated translucent operation buttons from translucent operation buttons that have not been operated according to whether or not the main light sources are lit.

In an engine igniting coil device comprising an ignition coil assembly potted integrally in a coil case by injecting melted insulating resin, a secondary coil is formed on a coil bobbin by bank winding an element wire in layers of wire turns one over another at a certain bank angle in an axial direction on the bobbin and by slope-winding of layers on the end portion of the bobbin by tapering the coil (by reducing the number of layers therein) in the winding direction. This allows setting a dielectric strength of interlayer insulation of the secondary coil according to the potential distribution therebetween, which is secured by forming an insulation resin layer of a reduced thickness between the coil case and the secondary coil of the secondary coil bobbin, thus realizing the compact engine-igniting coil device.

In an engine igniting coil device directly attachable to an igniting plug, both primary and secondary coil bobbins have flangeless ends, the secondary coil bobbin has inwardly protruding ribs for coaxially supporting the flangeless end of the primary coil bobbin mounted therein and the secondary coil bobbin also has a protrusion formed at its external wall apart from a high-voltage terminal of the secondary coil wound thereon and is coaxially mounted in a coil case by abutting its protrusion on an inner wall thereof, thus eliminating the possibility of damaging the bobbins by a large thermal stress produced in solidified insulating resin in a coil case by a differential thermal shrinkage in an axial direction and preventing a leakage current from a high-voltage side of the secondary coil bobbin to the coil case through a flange-like connection.

An ignition coil winding method for spirally winding an element wire in banks of wire turns one by one around coil bobbin provides in particular that a nozzle can vertically move toward and away from a coil bobbin according to a changing winding radius and can swing in the direction normal to the longitudinal axis of the bobbin to maintain constant tension of the element wire. This method also uses a nozzle whose opening diameter is 2 to 6 times larger than that of the element wire to eliminate oscillation of the element wire in the nozzle opening.
