摘要： A measuring probe for determining the physical stability of emulsions and dispersions, is constructed from a rod comprising a material which is electrically nonconductive at least on the rod surface. The rod carries at least two conductivity-measurement electrodes separated from one another along the rod. These electrodes are separately supplied with electricity via the interior of the rod at one rod end. A method for determining the physical stability of emulsions and suspensions involves placing an emulsion or dispersion a sample container, immersing a measuring probe in the filled sample container, and measuring the conductivity of the emulsion or dispersion continuously or at intervals over a given period of time using the conductivity-measurement electrodes.

摘要： This invention relates to a system and method for economically locating an ESD event with a reasonable degree of accuracy. It performs this function using a binary approach in which one or more binary ESD locator boxes are used. Each of these binary ESD locator boxes incorporates two antennas and performs the function of determining which of these antennas receives the ESD signal first. This determination establishes the ESD event as occurring to one side of a planar surface. By incorporating one or more additional binary ESD locator boxes, the system can determine whether an ESD event occurred within a two dimensional area or within a three dimensional area.

摘要： An automated test system is provided for evaluating characteristics of photoreceptors used in the electrophotographic process. The test system includes a dielectric material support adapted to receive said dielectric material one or more electrodes adapted to apply electrical energy from a source to a two dimensional area adjacent the support for storage by the dielectric material and a sensor for the electrical energy stored in the dielectric material and providing an output representation of the dielectric relaxation of the material in response to the stored energy over the two dimensional area. This test system provides advantages over conventional Electrostatic Charge Decay (ECD) methods by eliminating corona pre-charging and a moving detector when a full-length array is used. Also, this test system utilizes a lower cost current detector in comparison to conventionally used voltage detectors.

摘要： A tracer material is embedded in a component of electrical equipment to detect excessive wear of the component when it is exposed to an electrical arc. As the component wears, the tracer material becomes exposed to the electrical arc and emits electromagnetic radiation, which is monitored continuously. The tracer material is selected so that it emits electromagnetic radiation when it is exposed to an electrical arc that is distinct from electromagnetic radiation emitted by any other parts of the component.

摘要： A test system and data analysis procedure are provided for use in electrophotographic printing with a whole set of characteristics determined to be important for efficiency and high quality images. The test system and data analysis procedure characterize dielectric relaxation processes in materials in terms of charge transport parameters that may include intrinsic charge density, charge mobility, and charge injection from the contact surfaces. The materials may include photoconductive drums or belts, charging rolls, developer rolls, intermediate transfer belts and output media such as paper transparencies or textiles. The apparatus consists of a charging source, a voltage detector and a current detector in an open-circuit mode of measurement. The configuration closely simulates the actual application of the materials in electrophotography and thus, can yield information more relevant for the applications.

摘要： A stressing voltage is applied to a dielectric film (step S23). An A-SILC is monitored with stressing time and is plotted on a log-log scale (step S24). A straight line is applied to the plotting, a stressing time at which the line crosses a predetermined value of the A-SILC (a breakdown threshold) is obtained, and the obtained stressing time is predicted as the lifetime of the dielectric film (step S26).

摘要： An electrostatic force microscope wherein electrostatic force applied to the detector is determined through obtaining the field distribution on several different shaped detectors with the calculation of the voltage distribution near the detector with the Finite Element Method to direct the measurement of the absolute charge amount on surface under test so that one can define the differences between the analysis and the results from the parallel plate model. Of interest is how large the error in the charge detection occurs in conjunction with thickness change of dielectric materials to be tested. There is provided a detector with cantilever which has proper shape for the spatial resolution of 10&mgr; made out of nickel foil for an electrostatic force microscope and the electrostatic force which appeared on it has been calculated.

摘要： A particle detector for detecting particles flowing in a duct has a first triboelectric probe (5) for detecting the particles and a second triboelectric probe (3) for detecting a signal generated by contaminants on the particle detector. The presence of signal-generating contaminants on the particle detector will result in an error signal on the first probe (5) and a signal on the second probe (3). Therefore, the presence of a signal on the second probe (3) will indicate that the signal appearing on the first probe (5) includes an error signal. If the ratio of the magnitude of the signal generated on the second probe (3) to the magnitude of the signal generated on the first probe (5) exceeds a certain pre-defined limit, cleaning of the detector will be required.

摘要： A differential DC/RF bridge-configured flowcell particle detector includes a flowcell and an adjustable circuit model of the flowcell, which are differentially coupled through output amplifier circuits and galvanically isolated from sources of signal degradation. The output of the difference amplifier is coupled to a DC/RF discriminator and associated downstream processing circuitry. Respective amplitude and phase outputs of the DC/RF discriminator are used to control amplitude and phase adjustment circuits of the adjustable circuit model, so as to automatically track amplitude and phase variations in the non-linear behavior of the flowcell, to mirror the characteristic impedance of the flowcell, thereby making the bridge insensitive to variations in the flowcell.
