Abstract: A flat panel display device comprises a matrix (10) of X and Y drive lines and a plurality of selecting field effect transistors (12). Each FET (12) is selectively operable by applying a potential across an individual pair of X and Y drive lines for controlling activation of a corresponding optical transducer (14). A high value resistor (15) is interposed in series between the gate electrode (G) of each selecting FET (12) and associated drive line to minimize the effect a short circuit caused by a defective gate electrode establishing an electrical connection between X and Y drive lines. The resistance is preferably provided by a segment of undoped polysilicon in a polysilicon circuit line connecting each gate electrode with the associated X drive line.

Abstract: This invention relates to an optical fluid analyzing apparatus which includes transparent means (12, 13) of known refractive index (n1) providing a cell (14) for receiving a fluid sample of unknown refractive index (n2). A diffraction grating (10) is formed in an inner wall (11) of the cell. A light source (15) is positioned at an incident angle ( theta 0) with a grating to satisfy the Bragg condition. A pair of detectors (16, 17) intercept the 0th order and 1st order diffracted light. Circuit means (18) responds to signals generated by the detectors to provide an output indicative of the refractive index of the sample.

Abstract: A multiple electron beam cathode ray tube has a plurality of cathodes in a plane to form an array. Grids on the same substrate are positioned in spaced relation about the cathodes so that a plurality of individually controlled electron beams are formed when appropriate potentials are applied to the cathodes and grids.
