Abstract: A cover for covering an air bag in a motor vehicle has a thin elastic plastic skin, a rigid substrate and an intermediate layer of soft plastic foam. The skin has a tear seam and the substrate includes a door that is impacted by the inflating air bag and presses outward against the foam layer and the skin to tear the foam layer and the tear seam and then swing outward with a torn section of the foam layer and skin to form an opening in the cover for deployment of the air bag into the passenger space in the vehicle. The tear seam in the skin has a score line formed by partial perforations defined by tapered holes that are evenly spaced and formed at a controlled depth on the underside of the skin by a lasing method.

Abstract: A new physical construction for attaching a phosphor bronze terminal to a plastic bobbin assembly permits a lower component height and a reduced footprint size as well as providing improved positive mechanical locking of the bobbin pinouts to the bobbin. This mechanical locking is provided by bending the attached end of the phosphor bronze terminal by 90 degrees and inserting the terminal into the bobbin so that the inserted part of the terminal is inserted horizontally into the support member of the bobbin. In this new configuration the bent end embedded in the bobbin is parallel to the printed circuit board surface on which the bobbin is mounted preventing the phosphor bronze terminal from working loose due to vibration and motion in the vertical axis direction.

Abstract: A transformer (10) for mounting on a printed wire board includes a bobbin (14) held between two ferrite core slabs (12). The bobbin is wound with a primary winding (28) having a secondary winding (32) wound over it. The wire leads (30) of the primary winding lie in slots (26) in one of the flanges (20) of the bobbin which extend to terminals (24) of a terminal base (22) integral with the flange to isolate them from the secondary windings and leads (34).

Abstract: A circuit arrangement for starting a linear metal halide arc discharge lamp while in a transistor switching bridge inverter circuit in the running inverter mode. A high voltage pulse generator is connected to a trigger electrode which is arranged for capacitive coupling to the lamp to supply pulsed high voltage thereto. A synchronizing circuit serves to synchronize application of the high voltage pulse to the trigger electrode with the turn-on of either polarity of the switching inverter. An inhibit circuit prevents high voltage pulsing of the trigger electrode after lamp ionization when the lamp is in a normal operational mode.
