An internal combustion engine ignition coil device has an annular seal rubber at its lower side coil. An annular projection is provided on a part of the seal rubber and is pressed against the inner diameter surface of a plug hole. An air path is formed in part of a coil case by mounting the seal rubber into a groove, enabling inside and outside portions of the plug hole to communicate. A gas-permeable thin film resin member is bonded to an inlet of the air path.

An ignition coil device for an internal combustion engine, which has a superior waterproof property and can be reduced in size and easily produced. An annular seal rubber (2) is mounted to the lower side of an ignition coil device (1). An annular projection (2a) is provided on a part of the seal rubber and is pressed against the inner diameter surface of a plug hole. A substantially L-shaped groove for forming an air path (4) is formed in a part of a coil case (1a). The air path (4) is formed by mounting the seal rubber (2) into the groove, enabling the inside and the outside of the plug hole to communicate with each other. A thin film resin member (3) with a porous structure being permeable to gas but not to liquid is fixedly bonded to an inlet (4a) of the air path (4) to prevent water from entering the plug hole. Those features realize the ignition coil device for the internal combustion engine, which has a superior waterproof property and can be reduced in size and easily produced.

An ohmic electrode for electrically connecting a shielding metal film and a window layer is provided to a semiconductor light-receiving element in which stray light is controlled by the shielding metal film. In this semiconductor light-receiving element, the ohmic electrode is disposed such that it encircles a p+ diffusion region while kept in contact with the window layer on a substrate. Crack propagation from the edgewise region into the ohmic electrode is thereby impeded.

An object of the present invention is to provide an ignition coil for use in an internal combustion engine, offering improved water drainage performance, while achieving high waterproof performance with controlled entry of water in a plug hole. A high-voltage generating section 3 that generates a high voltage is housed inside a coil case 4. A plug hole seal 5 closes an opening in a plug hole 2 in which an ignition plug 21 is mounted. The ignition coil further includes a space portion 6 placed on an outer side portion of the high-voltage generating section 3 and an air path 9 for venting air between the space portion 6 and the plug hole 2. The space portion 9 has an open lower surface (an entirely open surface facilitates demolding).

An auxiliary core portion and a main core portion, including a magnet if the magnet is attached, are covered by a resin film or an elastomer film and fixed as a single assembly. In this state, a coil is attached to the assembly and a side core portion is assembled to the assembly. The auxiliary core portion and the main core portion, including the magnet if it is attached, can be supplied, as the single assembly, to an automated assembly line for ignition coils. It is not necessary to position such components on the assembly line. Thus, the workability of the automated assembly can be enhanced.

A plug driving apparatus comprising an annular rotary receiver stand for receiving containers, the receiver stand having container placing portions disposed at a plurality of locations thereon in circular arrangement, plug driver heads disposed individually above said placing portions, each of the heads having a sucker portion for sucking and retaining thereon plugs, a plurality of plug pick-up means, each having a retractable hooked portion adapted to be extended to and retracted from a point right beneath the plug driver head, fixed plug-feeder means for feeding plugs to the hooked portion, the plug driver head being adapted to be raised and lowered between an intermediate position where the sucker portion thereof sucks and retains thereon a plug held in the hooked portion and a lower position where plug driving operation is carried out and an upper limit of movement of the driver head. According to the invention, it is possible to manufacture such apparatus of compact construction which permits accurate and highly efficient plug-driving operation.
