| Number | Title | Issue Date |
| 7880582 | Layered electrically conductive material An electrical resistor has an electrically conductive stack, which includes a plurality of metal first layers and second layers. The stack allows to produce a highly anisotropic resistor, in which the resistance in the direction perpendicular to the layers is much h... | 02/01/2011 |
| 7154374 | Plated terminations Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology... | 12/26/2006 |
| 7062803 | Furniture headboards and footboards Disclosed is a bedstead board having at least one recess near a first or a second side. The at least one recess is configured to removably receive a roller of a patient transport system. In use, two bedstead boards are connected to a bed frame. Each of the two bedst... | 06/20/2006 |
| 6611256 | Touch screen dielectric separators A touch screen assembly for contact input systems, with the touch screen including a base substrate with an electrically resistive coating thereon. An array of reticulated spaced raised projections are formed on the inner surface, with the raised projecti... | 08/26/2003 |
| 6424339 | Touch screen assembly A touch screen assembly for contact input systems, with the touch screen including a base substrate with an electrically resistive coating thereon. An array of reticulated spaced raised projections are formed on the inner surface, with the raised projecti... | 07/23/2002 |
| 5997996 | Sheet-like pressure-sensitive resistance member having electrodes, method of making the same, and sheet-like pressure-sensitive resistance member An electrode-provided sheet-like pressure-sensitive resistance member includes a sheet-like pressure-sensitive resistance member which includes conductive particles arranged such that the conducting direction of the conductive particles intersects a surfa... | 12/07/1999 |
| 5990778 | Current-limiting resistor having PTC behavior The current-limiting resistor has two connection electrodes (1, 2) which are arranged parallel to one another, a resistance body (3) which has PTC behavior and with which large-area contact is made by the connection electrodes (1, 2) and at least one vari... | 11/23/1999 |
| 4677529 | Circuit board A circuit board for use in a keyboard has a lower insulating sheet, an insulating sheet, and an upper insulating sheet stacked on top of each other. Switch circuit patterns are formed on the upper and lower insulating sheets so as to be opposed to each ot... | 06/30/1987 |
| 4495524 | Part for a slide variable resistor A part for a slide variable resistor provided on an insulated support thereof with a film resistive layer adapted for a slide terminal to be slid along the surface thereof, which part is characterized in that said film resistive layer comprises a main res... | 01/22/1985 |
| 4069406 | Closing resistor switch for gas insulated circuit breaker A high voltage gas insulated circuit breaker in which a resistance shunts the main interrupter contacts to control the magnitude of the surge voltage experienced when the interrupter is closing. The resistance includes a resistor switch comprising a plura... | 01/17/1978 |
