Latest Patents

One of his latest patents is titled "Cermet resistive element for variable resistor." This invention features an improved resistive element that comprises a film-type resistive layer applied to an insulative substrate and then fired. An array of discrete, spaced apart islands of predominantly conductive material is applied to the resistive layer in a repetitive pattern with predetermined inter-island spacing. The islands possess a conductivity that is substantially greater than that of the resistive layer. In one preferred embodiment, the islands are formed of a conductive thick film ink that is screen-printed onto a cermet resistive layer through an appropriate mask and then fired. In another embodiment, the islands are formed of a conductive metal applied to the resistive layer by vapor deposition, sputtering, or ion implantation through a suitable mask. This invention provides a resistive element with lower contact resistance and improved contact resistance stability compared to prior art film-type resistive elements, while maintaining good linearity, setability, and resolution.
