Abstract: Apparatus for controlling the concentration of silver ions during the precipitating (212) of a silver halide emulsion in a precipitation vessel (80). The introduction of a silver salt and a halide salt is controlled in accordance with a preselected program, which in turn is responsive to the silver ion concentration measured in the vessel (80) by a silver ion sensor (114). Linearization of the output signal from the sensor is accomplished by converting (216) the sensor's output voltage into a concentration voltage through the use of a Nernst equation and by transforming (218) the concentration voltage into a variable value denoted Y representing a constant coefficient differential equation that is linear. The linear equation is then used to control (206) the addition of the silver salt and the halide salt to the precipitation vessel (80).

Abstract: The invention relates to a method and a device for determining the volumetric water content of mineral and/or organic mixtures by means of dielectric measurements. 
<??>The water content is therefore determined without an elaborate mixture-specific calibration. 
<??>For this purpose, an electromagnetic wave is applied to measuring electrodes of a probe and their complex reflection factor is measured. Then the water contained in the mixture is frozen out by suitable means and the measurement is repeated. From the two measured complex reflection factors and the known permittivities of water and ice, the water content of the mixture is then determined using a calibration curve specific to the apparatus.

Abstract: Disclosed is a method and apparatus for locating an abnormality in a gas-insulated electric device, operative to locate the spot of an insulation abnormality, which emerges inside a metallic container (3), from outside of said metallic container. A plurality of detectors (S₀-S n ) disposed at certain positions in the metallic container produce detected signals, from which spectrum strengths (YH) in a high frequency band of 500 MHz or above are evaluated, and a position which renders a maximum spectrum strength is calculated from the relation between the spectrum strengths and the installation positions of the detectors and is determined to be the spot (x) of partial discharge. The apparatus comprises a plurality of detectors (S₀-S n ) disposed at certain positions in the metallic container, means (21) for analyzing the frequency spectrum of detected signals provided by the detectors thereby to evaluate the spectrum strength, and means (22) for calculating a position, which renders the maximum spectrum strength, from the installation positions of detectors and the spectrum strengths and determining the position to be the spot of partial discharge. The detectors detect the propaga­tion of an electromagnetic wave caused by the partial   discharge, and the spectrum strengths are evaluated from the detected signals. Since the electromagnetic wave is attenuated under the influence of the wall resistance, etc. of the metallic container, different spectrum strengths result from detector signals depend­ing on the distance from the spot of partial discharge to each detector. Accordingly, a position which renders the maximum spectrum strength can readily be calculated from the relation between the magnitudes of spectrum strength of detectors and the installation positions of detectors, and the spot (x) of partial discharge can easily and promptly be located.

Abstract: A signal processing circuit for a solid-state imaging apparatus in which an imaging output signal from each solid-­state image sensor of an imaging section making use of spatial offsetting is digitized to form a detail signal for image enhancement by digital signal processing. A first delay circuit (21) having at least one delay unit with a delay time approximately equal to one horizontal scanning period provides the above mentioned delay time to a green color imaging signal of the digital output signal obtained by digitizing image output signals read from the solid-state image sensors. The signal synthesis is then performed in a first synthesis circuit (23) to limit the band of the green color imaging signal in the perpendicular imaging signal. A second delay circuit (22) having at least one digital delay unit having a delay time about equal to one horizontal scanning period provides the above mentioned delay time to one of the red or blue color imaging signals or combined red and blue color imaging signals of the above mentioned digital output signal. Signal synthesis is then performed by a second synthesis unit (24) to limit the band of the red or blue color imaging signal or the combined red and blue color imaging signals in the perpendicular direction. Equal amounts of the first and second synthesis signals are summed together in a summation unit (25) so as to be outputted as the horizontal detail signal via digital filter unit.
