Abstract: A substrate coated with a plurality of thick films wherein conductive layers are wholly prepared from conductive paste. The present invention offers the advantages that the drawbacks accompanying the conventional conductor of silver-palladium base are overcome by forming a resistor having a required resistivity and a high reproducibility. A conductive paste and insulative paste are fired at a lower temperature than that at which the resistor paste is fired, without reducing the adhesion strength of the conductive layer to the substrates. A low temperature melting point crystalline composition is used as an insulative layer to ensure that the resistance of the resistor is not adversely affected by repeated firings.

Abstract: A method of preparing ceramic monolithic structures with an internal cavity and passageways is described. A thin sheet of a ceramic material is formed by spreading the material on a glass plate with a doctor blade. Individual sheets of the material are cut or punched to form predetermined holes, channels or various shapes therein. These individual sheets are then stacked to form a layered structure. A supporting media such as paraffin wax is injected into the holes and channels to completely fill them with the media. The layered structure is then pressed by unipressing and/or isostatic pressing followed by a prefiring step to remove the supporting media. Once the supporting media had been completely removed, the layered structure is then sintered to form a monolithic structure containing precise predetermined internal cavity and passageways.

Abstract: A semiconductor die for plastic encapsulation having an adhesion promoter selectively disposed on an outer surface enabling better adhesion between the semiconductor die and a plastic encapsulation. The improved adhesion allows for less relative motion between the semiconductor die and the plastic encapsulation. The reduction of relative motion significantly decreases the delamination progression throughout the semiconductor device and allows for an increased semiconductor device lifetime.

Abstract: An improved dielectric ink for the fabrication of multilayer integrated circuits is disclosed. The subject inks comprise a devitrifying magnesium-barium-aluminum-zirconium-borophosphosilicate glass frit, an organic vehicle and, optionally, a suitable ceramic filler material. Dielectric layers and stand-alone substrates formed from the subject inks are characterized by good mechanical strength, heat resistance and exceptional density. The subject inks are particularly useful in the fabrication of multilayer circuit structures based on copper since their exceptional density renders them resistant to penetration by flux materials from the copper conductor layers.

Abstract: An impermeable encapsulation system for integrated circuit chips utilizes a polyimide-siloxane block copolymer as an undercoat applied to the chip surface and an impermeable outer coat comprised either of a non-reactive metal, such as titanium, tantalum or aluminum, or an amorphous semiconductor material comprising silicon-boron. All of these materials may be effectively applied at temperatures sufficiently low to avoid damaging the chip.

Abstract: The invention relates to an effervescent couple which comprises a mixture of mono-and di-alkali metal citrate as well as to a process for preparing same. The process comprises partially neutralizing citric acid by reacting an alkali metal carbonate or bicarbonate with citric acid and water and controlling the amount of carbon dioxide released during the reaction by stopping the reaction when a certain amount of citric acid has been neutralized. In a preferred embodiment the reaction is stopped when from about 24% to about 54% of the potential amount of carbon dioxide has been released.

Abstract: A multilayer circuit board consisting of multiple circuit layers supported on sheets of PTFE or PTFE containing a fibrous stiffening agent, said circuit-bearing sheets being joined in fixed relative positions by means of separating layers of a adhesive unsintered tetrafluoroethylene resin.

Abstract: This invention relates to chewing gum compositions containing local anesthetics. These compositions readily release the anesthetic such that it is available to anesthetize the throat and mouth areas, thereby providing relief to irritated areas. Increased availability of the anesthetic is possible by the formation of a sweetener/anesthetic premix. The preferred anesthetic is hexylresourcinol.

The glazing contains two sheets of glass separated by a space of dehydrated air and maintained by a cross-braced frame, of which at least the surface in contact with the glass is butyl and/or polyisobutylene rubber-based mastic and is covered with a peripheral injection, which adheres in a cohesive maner to the mastic of the cross-braced frame.

Abstract: A reusable thermocolor ribbon for thermal transfer printing is described comprising a layer of a melt-applied color on one side of a plastic foil as carrier, where the melt-applied color contains a wax or wax-like substance, a pigment and an organic binder. A coating liquid which contains a thermoplastic binding agent in solution and the meltable wax or wax-like substance in finely dispersed solid form, is applied to the carrier of the thermocolor ribbon, where the coating liquid represents as solvent agent a mixture of a solvent and non-solvent for the thermoplastic binding agent at room temperature. The non-solvent/solvent mixture is evaporated while simultaneously its solvent capability for the plastic binding agent is reduced. This thermocolor ribbon can be used more than 20 times without impairment of the print quality. A process for preparing the thermocolor ribbon is also detailed herein.

Abstract: A novel capsule-like medicament, method for producing such medicaments and apparatus are disclosed. The method provides a procedure for coating solid cores, such as caplets, with gelatinous coatings to produce a shiny, capsule-like medicament. Such medicaments are achieved by individually dipping and drying first one end, and then the other end, of each caplet to provide a coating which is smoother and easier to swallow than an uncoated caplet. The production of these capsule-like medicaments is readily facilitated by simple and inexpensive modifications which can be made to existing empty gelatin capsule making equipment.
