Abstract: ABSTRACT A ceramic insulator and a method for the production thereof are disclosed.  The method comprises the steps of pressing ceramic batch around a contoured arbor having at least two longitudinally extending fins to form an outer piece having a bore with grooves therein corresponding to the fins, removing the arbor from and contouring the piece to a desired external shape, pressing ceramic batch to form an inner piece, and contouring the inner piece to fit within the bore of the outer piece.  The inner piece is then positioned within the bore of the outer piece and both pieces are fired whereby the insulator is produced in which the contoured surface of the inner piece closes the grooves in the bore of the outer piece to form slots extending longitudinally within the ceramic insulator.  Also disclosed is a method which involves firing the inner piece, positioning the fired inner piece within the bore of the unfired outer piece, and then firing both pieces together.  A ceramic insulator according to the invention is useful as a support for an oxygen sensor which can be placed in the exhaust gases from an internal combustion engine and used to measure oxygen content thereof to enable control of the air-fuel ratio at which the engine is operated so that, for example, emissions can be minimized.

Abstract: SYSTEM FOR MONITORING UTILITY USAGE             ABSTRACT OF THE DISCLOSURE         Electronic circuitry monitors the electrical energy consumption of a system and displays the current cost of the energy usage.  The projected monthly billing cost is calculated at the current rate of consumption, and an alarm signal and control output are generated if the projected cost is higher than a budget amount.  Energy consumption is sensed optically at the electric meter and a proportional number of high frequency pulses are added to the household electrical network.  These pulses are remotely sensed at any point within the household electrical network and are fed to a microprocessor for counting and conversion to cost parameters.          Clock pulses are also directed to the microprocessor for calculating the billing period and for displaying time parameters.  A keyboard enables initializing and modifying the cost and time parameters in the microprocessor.

Abstract: HIGH VOLTAGE SEMICONDUCTOR DEVICE HAVING    IMPROVEMENTS TO THE dv/dt CAPABILITY        AND PLASMA SPREADING Abstract of the Disclosure A semiconductor device used for high voltage applications exhibits reduced susceptibility to being inadvertently turned on by capacitive charging currents generated by relatively high voltage transients impressed across an anode and a cathode of the device.  The capacitive charging currents are manifested as gate currents which in a thyristor render the device conductive it they exceed a critical valve, and in a transistor are multiplied by the current gain.  A capacitor integral with the semiconductor device structure is coupled to a gate region of the device to divert a portion of transient-generated capacitive  charging currents, thereby reducing the associated gate currents and improving the dv/dt capability of the device.
