摘要:
A pharmaceutical composition for slow release of active ingredient in the gastrointestinal tract, comprising a plurality of active ingredient-containing particles coated with a material insoluble in gastric and intestinal juices, where the particles have as core a homogeneous mixture comprising an active pharmaceutical ingredient and a polymer insoluble in gastric and intestinal juices, with an average internal pore diameter not exceeding 35 μm, makes efficient and pH-independent delaying of release possible even with comparatively small amounts of polymer. It is additionally distinguished by a long shelf life and is particularly suitable also for nonspherical particles.

A system, method, and apparatus for injection molding conductive bonding material into a plurality of cavities in a surface are disclosed. The method comprises aligning a fill head with a surface. The mold includes a plurality of cavities. The method further includes placing the fill head in substantial contact with the surface. At least a first gas is channeled about a first region of the fill head. The at least first gas has a temperature above a melting point of conductive bonding material residing in a reservoir thereby maintaining the conductive bonding material in a molten state. The conductive bonding material is forced out of the fill head toward the surface. The conductive bonding material is provided into at least one cavity of the plurality of cavities contemporaneous with the at least one cavity being in proximity to the fill head.

摘要:
A wafer-scale apparatus and method is described for the automation of forming, aligning and attaching two-dimensional arrays of microoptic elements on semiconductor and other image display devices, backplanes, optoelectronic boards, and integrated optical systems. In an ordered fabrication sequence, a mold plate comprised of optically designed cavities is formed by reactive ion etching or alternative processes, optionally coated with a release material layer and filled with optically specified materials by an automated fluid-injection and defect-inspection subsystem. Optical alignment fiducials guide the disclosed transfer and attachment processes to achieve specified tolerances between the microoptic elements and corresponding optoelectronic devices and circuits. The present invention applies to spectral filters, waveguides, fiber-optic mode-transformers, diffraction gratings, refractive lenses, diffractive lens/Fresnel zone plates, reflectors, and to combinations of elements and devices, including microelectromechanical systems (MEMS) and liquid crystal device (LCD) matrices for adaptive, tunable elements. Preparation of interfacial layer properties and attachment process embodiments are taught.
摘要:
Methods of forming a conductive structure on a substrate prior to packaging, and a test probe structure generated according to the method, are disclosed. The conductive structure includes a high aspect ratio structure formed by injected molded solder. The invention can be applied to form passive elements and interconnects on a conventional semiconductor substrate after the typical BEOL, and prior to packaging. The method may provide better electromigration characteristics, lower resistivity, and higher Q factors for conductive structures. In addition, the method is backwardly compatible and customizable.

摘要:
The invention relates to solid medicinal forms containing at least one active ingredient and at least one pharmaceutically compatible, water soluble drying agent which is selected from the group consisting of trimagnesium dicitrate and/or calcium chloride, the solid medicinal form having a drying loss of at most 6% and a relative equilibrium moisture content of 25% or less. The invention also relates to solid medicinal forms containing a moisture-sensitive active ingredient and trimagnesium dicitrate.
摘要:
A process for producing a solubilized ibuprofen, preferably in the form of a granulate, the process comprising the steps of: providing a mixture comprising solid ibuprofen and a first base selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium glycinate, potassium glycinate and tribasic sodium and potassium phosphates and mixtures thereof, and reacting the ibuprofen and the first base in essentially dry state. The obtainable granulate and the pharmaceutical compositions and dosage forms that may be produced therefrom are distinguished by their high solubility and rapid disintegration and dissolution in aqueous media, by their good flow properties and compressibility, by rapidly achieving onset of analgesic effect.
