    Abstract: A capacitor containing a solid electrolytic capacitor element and a conductive adhesive disposed between the capacitor element and another optional capacitor element, an electrode termination, or both, is provided. The conductive adhesive contains a plurality of spacer particles that are substantially spherical and have a relatively large diameter. The present inventors have discovered that the use of spacer particles having the desired size and shape can provide multiple benefits to the resulting capacitor. For example, the spacer particles can limit the degree to which the adhesive is compressed during manufacture, thereby ensuring that it will have the minimum thickness needed to achieve a reliable mechanical connection to the desired part. Further, when multiple capacitor elements are employed, the spacer particles can also help ensure that proper spacing is achieved between the different elements upon manufacture of the capacitor.

  • Patent number: 4618916
    Abstract: Particular circuit component structures, and methods of using such structures, based upon a lipid bilayer membrane, a first liquid phase that is in contact with one surface of the membrane and a second liquid phase that is in contact with the other surface of the membrane. A substance inducing voltage-dependent conductance in the membrane is present in one of the liquid phases.

  • Patent number: 4517622
    Abstract: Signal conditioning circuitry for a three plate capacitive pressure transducer eliminates the effects of parasitic capacitance in the transducer's output, to provide a true indication of sensed pressure magnitude as an electrical signal equivalent of the instantaneous value of only the pressure responsive capacitance of the transducer.

  • Patent number: 4488203
    Abstract: Disclosed is an electrochemical double-layer capacitor which comprises a capacitor element having a pair of polarization electrodes and a spacer interposed between the electrodes and impregnated with an electrolyte solution, and a film enclosure made of two film sheets which have been thermally bonded by heat sealing along their entire periphery. The film sheets are bonded directly or through a heat-fusible resin plate having an opening in which the capacitor element is received. When using the heat-fusible resin plate, the film sheet is made electrically conductive to allow easy connection to electric appliances or allow easy connection of a plurality of capacitor elements in series.

  • Patent number: 4435742
    Abstract: This specification discloses an electrochemical structure having two separate electrochemical cells using liquid electrolytes separated by a material or region which ca take up the electrochemically active species appropriate to the cells in neutral form. Combined with external circuitry, the structure can be made to exhibit transistor action and further can be made to show ac voltage, current and power gain. For example, transistor action occurs with a structure composed of two liquid electrochemical cells using a sulfuric acid electrolyte separated by an enclosed volume. In normal operation, one cell, acting as an emitter, emits hydrogen from a hydrogen ambient into the enclosed volume, which acts as a base region, where it is collected and returned to the ambient by the opposing cell, acting as a collector.

  • Patent number: 4341989
    Abstract: The invention relates to a device for phase compensation and excitation of a multiphase asynchronous machine, especially one to be driven as a generator and to be operated at low speed. Each winding (1 to 3) in the machine is connected in series or in parallel with a capacitive element consisting of a bank of capacitors (4 to 6) having at least one pair of series connected electrolytic capacitors (7, 8), having in each pair equal terminals interconnected.

  • Patent number: 4332003
    Abstract: This specification discloses an electrochemical structure having two solid electrochemical cells separated by a material or region which can take up the electrochemically active species appropriate to the cells in neutral form. Combined with external circuitry, the structure can be made to exhibit transistor action and further can be made to show ac voltage, current and power gain. For example, transistor action occurs at elevated temperatures, such as at 800.degree. C., with a structure composed of two ceramic zirconium dioxide electrochemical cells separated by an enclosed volume. In normal operation, one cell, acting as an emitter, emits oxygen from an ambient atmosphere into the volume, which acts as a base region, where it is collected and returned to the ambient by the opposing cell, acting as a collector.

  • Patent number: 4187161
    Abstract: An electrical element which comprises at least one circuit component consisting of a solid ionic conductor, and wherein the electron flow through the ionic conductor is supressed without substantially hindering the ion flow therethrough, by at least one pn junction formed across the direction of ion flow. The pn junction is formed by at least one of p-conductive and n-conductive zones in or adjoining the ionic conductor and which is capable of being reversed-biased relative to the electron flow. The p-conductive and n-conductive zones comprise a material conductive of the same ions as the ionic conductor.
