Abstract: A process is described for infusing an additive into a polymer using a compressed fluid that is normally a gas at room temperature and pressure. The additive must have some degree of solubility in the compressed fluid and the solution of compressed fluid and additive must have some degree of solubility in the polymer. In accordance with the process, the solution of the normally gaseous fluid and additive and the polymer are brought into contact under pressure until a desired quantity of the solution is absorbed into the polymer. The compressed fluid then is diffused from the polymer leaving additive infused within the polymer.

Date Nov. 20, 1986.A concrete-reinforcement bar, especially a tension bar, provided with hot-rolled, helically-arranged ribs, which are located on two mutually-facing sides of the periphery of the bar and form parts of a thread. The ribs of the thread extend over roughly a third of the periphery of the bar and are inclined toward one another with their front faces which merge into the smooth bar surface of the core cross section. In order to improve the fatigue strength, and mechanical strength, and to simplify the production of the threaded bars and reduce the required tolerances, the cross-section of the bar has a regular, smooth undulating profile in an axial plane in the region of each rib (2); the wave-shaped tops of the ribs and the valleys between the ribs thus form cavities in the otherwise circular core cross-section. The cavities penetrate into the core cross-section only at localized points.

Title: Additive technique for multilayer wirings
IPC: H05K3/46
Filed: 1988-02-17
Granted: 1993-06-23
Abstract: According to the invention, an additive technique for multilayer wirings is intended to be designed which has both a high conductivity of the conductor tracks and a large packing density. In addition, despite conductor tracks which are located close together, the cross- talk must be small. According to the invention, a light-sensitive dielectric material with a dielectric constant of  epsilon  < 3 is used for holding the conductor tracks and through-contacts. A carrier plate is coated with this dielectric material, is illuminated with the structure of the through-contacts and conductor tracks and is developed. This process is followed by non-electrical deposition of metal and subsequently by galvanic covering. After that, the depressions are finally filled during a galvanic deposition of the base surface. After removal of the galvanic covering, etching the non- electrically deposited metal coating and levelling, the process sequence can be repeated. The specific field of application is multilayer micro-wirings. <IMAGE>
