An ultracapacitor having two porous organic membrane electrodes is made from microporous polymer substrates (10). The surface of the polymer substrate and the walls of the micropores (30) are coated with metal oxides. Both sides of the substrate can be coated with the conductive materials. The film can be a carboxylic ion-exchange material dispersed in a microporous copolymer matrix, and the film can be supported on a woven nylon substrate. The two electrodes (82, 84) are situated substantially parallel to each other, with the coated surface of one electrode facing the coated surface of the other electrode. An ionic electrolyte solution (89) fills the gap (86) between the electrodes.

Electrical energy storage device having a porous organic electrode

A rechargeable electrical energy storage device (20). The cell has two electrodes (28, 36) constructed from a similar organometallic compound (30), and the electrodes are electrically connected by an ion carrying electrolyte (32). The electrodes are also physically separated from each other by a barrier (34) that will pass ions but not electrons. In one embodiment of the invention, the electrodes are ferrocene, and the electrolyte is sulfuric acid.

Rechargeable electrical energy storage device having organometallic

An electrode for a rechargeable electrical energy storage device has a substrate and an electrochemically active material deposited on the substrate. The electrochemically active material provides electron transfer between itself and an electrolyte. The electrochemically active material is a mixed-valence complex containing at least two metal atoms and at least one ligand attached to the metal atoms, and has metal-to-metal bonds where the metals exist in multiple oxidation states such that electron transfer between the metal atoms in the complex or between discrete complexes occurs. A rechargeable electrical energy storage device (20) has two electrodes (28, 36) constructed from a mixed-valence complex (30), and the electrodes are electrically connected by an ion carrying electrolyte (32). The electrodes are also physically separated from each other by a barrier (34) that will pass ions but not electrons.

Mixed-valence complex electrodes for a rechargeable electrical energy

A method of photodelineating an adhesive on a substrate. The first step (10) is to coat the substrate with a layer of photopolymeric adhesive, typically spin coated. The adhesive is then briefly `soft baked` at a moderate temperature to set it (20). Portions of the adhesive are then selectively exposed to actinic radiation to partially cure them, while other portions are not exposed (30). A photomask is used to selectively expose the photopolymeric adhesive to ultraviolet light at an intensity and for a time sufficient to partially cure the photopolymeric adhesive. The adhesive is developed (40) to selectively remove those portions that were not exposed to radiation, usually in an appropriate solvent, creating a pattern in the adhesive. The developed adhesive pattern is then heated for a time and temperature sufficient to completely cure it (50).

A shielded, erasable-programmable-read-only-memory (EPROM) package is provided. A circuit carrying substrate (10), contains an area for mounting an EPROM chip (16), having conductive interconnecting patterns (12) adjacent to the chip mounting area. The EPROM chip is mounted on the circuit carrying substrate, and the pad electrodes on the EPROM chip are connected to pads on the conductive patterns of the substrate by wire bonds (17) or other means. An ultraviolet (UV) light transmitting resin (18) is transfer molded onto the circuit carrying substrate, covering the EPROM chip (16) and the wire bonds (17) so as to provide an optical path through the material to the top surface of the EPROM chip, and sealing the EPROM chip from the exterior of the package. An adherent metal coating (19) is sputtered over the transfer molded resin, and the metal coating is coated with a protective organic resin (15). Both the metal coating and the organic resin are at least partially transparent to ultraviolet light.

Shielded EPROM package

A process for manufacturing a substrate (12) used in a device (10) for containing a liquid crystal fluid (30) between two spaced electrodes. A plurality of spacers (35) is distributed on a first surface of a substrate by coating the first surface with an admixture of spacers dispersed in a liquid (36). The admixture is agitated during the applications step in order to maintain a uniform dispersion of the spacers in the liquid. The liquid is then evaporated from the substrate surface, leaving a plurality of spacers distributed on the substrate. Preferably, an ester alcohol dispersant is employed in the admixture in order to facilitate dispersion of the spacers in the liquid. Ultrasonics are preferred as the means of agitating the admixture during application. Ultrasonic energy can also be applied to the substrate during application of the admixture to the substrate. Ultrasonic energy can also be applied to the admixture at the point of application (44) of the admixture onto the substrate.
