    • A unique method and structure is provided for testing high voltage equipment with great accuracy of voltage levels to be measured, repeatability of measured levels from one piece of test equipment to the next, no need for recalibration of test equipment, and sufficiently low current during testing that the test equipment can be powered by the same supply that powers the device under test. The device of this invention can be used to measure not only logical one and logical zero voltage levels of the device under test while under specific loads but can also be used to meausre transition time from one logic state to another.The circuit of this invention provides an output signal which can have three states reflecting a high logic level from the device under test, a low logic level from the device under test, and an intermediate level indicating that the device under test is in transition from one logic level to another or has failed the test.

    • A temperature sensitive electrical element and method of making the same comprising the steps of applying to the surface of a substrate and firing a mixture of glass frit and particles of titanium dioxide (TiO.sub.2), and titanium metal. The mixture is fired in a non oxidizing, inert, or reducing atmosphere at a temperature which softens of the glass frit. When cooled, an element is provided with a glass film strongly bonded to the substrate and having dispersed therein conductive particles mainly of titanium oxide (Ti.sub.2 O.sub.3). The element produced can be terminated by the use of electroless plating and provides a substantially linear resistance to temperature characteristic and a relatively high temperature coefficient of resistance.

    • A vitreous enamel resistor, and method of making the same comprising the steps of applying to the surface of a substrate and firing a mixture of glass frit and particles of a precious metal oxide such as iridium oxide, ruthenium oxide, and mixtures thereof. The mixture is fired in a neutral, inert, or reducing atmosphere for a time and at a temperature resulting in a controlled partial dissociation of the oxide and softening of the glass frit. When cooled, a resistor is provided having a glass film with conductive particles therein strongly bonded to the substrate. The resistor produced can be terminated by the use of electroless plating.
