Abstract: A fuel pressure regulator valve (10) of the type commonly used in automobile fuel injection systems. The invention relates to improved retention of the valve element within the mount that is carried by the diaphragm assembly (14). The valve element is a truncated sphere (32) and the retention is by means of a circular washer (36) that fits into a circular recess formed in the mount (28) around the cavity that contains the sphere. The truncated circular face of the sphere protrudes through the washer (36) so that it can coact with the valve seat (24). The inside diameter of the washer (36) is closely controlled and this controls the allowable travel of the sphere (32) within the cavity. The washer (36) is retained on the mount (28) by crimping the edge of the circular recess over the outside diameter of the washer.

Abstract: A voltage is provided by a master circuit and received by a plurality of slave circuits over a bus. The master circuit includes a V bb  reference circuit, a temperature compensation and V cse  reference circuit, and a voltage step-up and buffering circuit coupled to the bus. Each of the slave circuits has a pair of transistors coupled to the bus in an emitter-follower configuration to step down the voltage from the master circuit and to provide a voltage reference. The voltage provided to the bus varies as it propagates through the bus. Accordingly, a plurality of unconnected resistors are formed in the portions of the silicon substrate which contain the master and/or slave circuits. When formed in the master circuit, the resistors are located in the V bb  reference circuit. When formed in the slave circuit, the resistors are located in close proximity to the output transistors. One or more of the resistors may be selectively coupled to its respective master or slave circuit for compensating for voltage drops along the bus.

Abstract: An improvement for a method for detecting the presence of an analyte in a sample by the interaction of the analyte with a specific binding compound to form a complex in a reaction medium, in which formation of the complex is detected by measurement of light emitted by a luminescent molecule used as a label on a component of the specific binding system that forms the complex, is provided in which the improvement comprises using as the label a photoprotein bound to a luminescent molecule, wherein the luminescent molecule remains bound to the photoprotein without emitting light in the absence of an external trigger; reducing background light emission in the reaction medium by contacting the reaction medium with the apophotoprotein form of the photoprotein prior to introduction of the photoprotein label to the reaction medium; and adding the trigger to the reaction medium after formation of the complex.

Abstract: Disclosed are an oxide superconductor, and an optimum process for producing the same. The oxide superconductor comprises a base material phase including an oxide superconducting material, the oxide superconducting material including barium (Ba) at least and being free from grain boundaries, and precipitation phases contained in an amount of 1 to 50% by volume in the base material phase and dotted therein in a manner like islands, the precipitation phases being oxides of a metal selected from the group consisting of silicon (Si), aluminum (Al), zirconium (Zr), magnesium (Mg), titanium (Ti), strontium (Sr), tungsten (W), cobalt (Co) and vanadium (V), and being products of decomposition reaction of the base material phase. In the production process, the constituent materials are treated thermally at a partially melting temperature in order to give the above-described novel structure to the oxide superconductor. Thus, the precipitation phases are dotted in a manner like islands in a sea of the base material phase being free from the grain boundaries, and the precipitation phases work as the pinning centers. Therefore, the oxide superconductor exhibits a high "Jc" value.

Abstract: A method of manufacturing a colour filter for a liquid crystal cell comprises forming a plurality of patterns, each of a respective dye intermediate material, on a carrier element. The patterns of dye intermediate materials are then brought into contact with a substrate layer, supported on a glass substrate, under the application of heat and pressure. The substrate layer, such as a polyacrylonitrile layer, contains free acid groups which interact with the dye intermediate materials to form the colours of the colour filter in the substrate layer. 
     The method permits the actual formation of the colours on the substrate to be effected in a single alignment step, minimising wastage of the relatively expensive glass substrates. Furthermore, as the dyes providing the colours of the filter are chemically part of the substrate layer, they are very resistant to leaching by the liquid crystal materials.

Abstract: MRI images are selectively resized or "zoomed" by zero padding the time domain data. Fourier Transformation of the time domain data after zero padding provides spatial domain data which when displayed provide an image that is resized relative to images provided from the time domain data without zero padding. A "zoom" or magnification factor can be selected and the quantity of padded zeros varied in response to the zoom factor to provide different zoom ratios. Restricting zoom factors to certain values permits the fast Fourier Transform to be used in Fourier Transformation.
