| Number | Title | Issue Date |
| 7167075 | Dual design resistor for high voltage conditioning and transmission lines A dual resistor for eliminating the requirement for two different value resistors. The dual resistor includes a conditioning resistor at a high resistance value and a run resistor at a low resistance value. The run resistor can travel inside the conditioning resisto... | 01/23/2007 |
| 7002447 | Fuel tank resistor card having improved corrosion resistance A resistor card for a fuel level sensor has improved resistance to corrosion and wear. The resistor card has a substrate with a resistive layer and a conductive layer. A nickel layer covers the conductive layer. A nickel-gold alloy layer covers the nickel layer. The... | 02/21/2006 |
| 6747544 | Electric switch An electric switch (1) having digital switch position detection includes a switching device (2) for contacting switch contacts associated with individual code tracks (A, B, C), different switch contacts being contacted by the switching device in differ... | 06/08/2004 |
| 6507270 | Linear operation type electric part The present invention provides a linear operation type electric part in which a spring member for restoring the movement of a movable member and a spring member for preventing the backlash of the movable member are formed of the same kind of coil spring, ... | 01/14/2003 |
| 4978939 | Settable resistor A settable resistor has a resistance path array (4) to which is allocated a contact piece (9) which is guidable in the longitudinal direction (13) over the resistance path array and has an adjusting device for the position of the contact piece. In order n... | 12/18/1990 |
