Patent EP-0031538-A2 (EP)
Inventor: SCHUTZ WILHELM PROF DR-ING
IPC: B29B11/00
Filed: 1980-12-16
Abstract: Zur Aufbereitung von aus Abfallstoffen erhaltenem Polyurethan durch Alkoholyse oder Acidolyse wird das Polyurethan zunächst mechanisch zu einem Ausgangsmaterial zerkleinert und anschliessend bei einer Temperatur von mehr als 120°C mit Lösungsmitteln behandelt. Zumindest zu Beginn der Lösungsmittelbehandlung, die bis zur Verflüssigung des Ausgangsmaterials führt und bei einer Reaktionstemperatur von unter 200°C durchgeführt wird, erfolgt eine Fortsetzung der mechanischen Zerkleinerung des bereits im chemischen Abbau befindlichen Ausgangsmaterials. Durch dieses Verfahren ergibt sich bei niedrigerer Temperatur eine kürzere Behandlungsdauer bis zur vollständigen Lösung des Ausgangsmaterials, ohne daß dabei qualitätsmindernde Verfärbungen auftreten oder ungelöste Rückstände verbleiben. Die Anlage zur Durchführung des Verfahrens hat einen aus Vorratsbehältern (1-3) beschickten Mischer (6), an den austrittsseitig ein Reaktor (14) angeschlossen ist, in dem Scherkräfte ausübende und in beiden Richtungen in Rotation versetzbare Scherelemente (61) auf das Ausgangsmaterials einwirken, die auf einer hohl ausgebildeten, beheizbaren Welle angeordnet und von einem aus hohl ausgebildeten, beheizbaren Sektoren (23) zusammengesetzten Reaktormantel (24) umgeben sind. In diesem Reaktor erfolgt eine Verbesserung des Wärmeübergangs an die Masse, so dass eine einheitliche Temperaturverteilung und damit eine verhältnismäßig kurze Reaktions- und Lösezeit erreichbar ist.

Abstract: Beryllium ions are implanted into a germanium substrate. The carrier concentration profile is shown grapically in Figure4A. 
     The substrate is heat treated at a temperature in the range from 400°C to 700°C to diffuse beryllium into the substrate. 
     A surface concentration of beryllium of 10 17  cm -3  or more can be obtained. 
     The relatively low temperature of heat treatment avoids adverse effects on the substrate. Deep diffusions of beryllium can be obtained. 
     p-type guard rings, p-type channel stoppers and p-type islands can be formed.

Abstract: This disclosure relates to a programmable timing pulse generator which employs a memory in which plurality different sequences of timing signals can be stored, which sequences can be programmably accessed to achieve any set of timing signals as might be required by the system. This readily allows the circuit designer to create a system in which certain timing signals may be required at particular intervals but not at regular intervals, and also allows the designer to create a system in which the rate at which the timing signals are generated can be readily changed by merely accessing a different portion of the memory in which the timing signals are stored.

Abstract: This invention relates to an apparatus and process for writing video information in the form of a frequency modulated signal upon a video disc member and for recovering the video information from the video record is described. The video disc member (10) formed by the writing apparatus is also described. The writing apparatus includes a laser (30) as a source of a laser write beam (29) and a write optical system (40) for directing the stationary laser write beam to a moving video disc member. The video disc member comprises a substrate member carrying a light responsive coating (26) at least one surface. The write optical system focuses the beam to a small spot of light approximately one micron in diameter upon the light responsive layer. The intensity of the focused spot is changeable under the control of a light intensity modulating assembly (44). This light intensity modulator changes the intensity of the write laser beam with respect to a predetermined threshold intensity sufficient to form a first type of indicia (37) in the coating. A read system (165) is employed to retrieve the video signal stored on the video disc member. This read system includes a read laser (150) for generating a read beam, and a motion control assembly for rotating and translating the video disc member relative to the read light beam. A read optical system directs the read beam to impinge upon the successively positioned specular light reflective and non-specular light reflective regions (37, 38) carried by the video disc member. The read optical system also collects the light (150) reflected from these regions. The reflected light beam is intensity modulated by the specular light reflective and non-specular light reflective regions. The read optical system also directed the reflected light beam to a light sensing circuit for changing the intensity modulated reflected light beam to a corresponding frequency modulated electrical signal (165) which is representative of the video signal stored on the video disc member. Circuitry is described for using a triangular frequency modulator (FIGURE 14C) for driving a Pockels Cell (68) and for obtaining a sinusoidal-shaped light modulation output signal from the linear polariser (70). The output from the linear polariser is adjusted such that the half power point from the polariser equals the threshold power level of the material forming the information storage layer. A second harmonic bias circuit (264) is employed for removing the second harmonic intermodulation distortion of the modulated write beam.

Abstract: A magnetic bubble memory device comprises:
     a magnetic layer which has a first region having the easy axis of magnetization extending in a certain direction and a second region surrounding said first region and having the easy axis of magnetization substantially perpendicular to that of the first region, said first region defining at least one major loop pattern (15) for propagation of information bubbles (20, 20', etc.) and a plurality of minor loop patterns (17-1, 17-2, 17-3) for storage of information bubbles; and an electrical conductor pattern (18) deposited on said magnetic layer thereby constructing transfer gates. The major loop pattern is provided, at portions thereof opposite to the ends of the minor loop patterns, with gaps (G-1, G-2, G-3) through which the bubbles (20', 20") are transferred between the major loop pattern and the minor loop patterns. Each transfer gate is driven by means of a convex-shaped pulse of transfer current. Preferably the conductor pattern does not overlap the minor loop patterns, and the ends of the minor loop patterns are flat or concave. Neighbouring minor loop patterns may be connected at their ends, and the minor loops may have gaps along their length, so as to create a full-length bubble propagation path running continuously along the entire periphery of the multi-line minor loop pattern.

Abstract: A semiconductor chip (14) is flip-chip mounted to conductors on a substrate by depositing layers of chromium (24), copper (26), and gold (28) on the chip (or the substrate), forming solder mounds (30) on said layers, and reflowing the mounds before or during the flip-chip mounting. Preferably, the copper layer is about 0.08-0.25 µm and the gold layer no more than 0.25 µm thick. Limiting the thickness of these layers reduces mechanical stress in the connection and these avoids cracking of the parts.

Abstract: A process for the separation of sonds from nquid hydrocarbons in which liquid hydrocarbons compnsmg oils, asphaltenes and pre-asphaitenes containing insoluble solids are contacted with a volatile solvent compatible with the liquid hydrocarbons for solubilizing said oils, aspnaltenes and pre-asphaltenes. The liquid hydrocarbons containing solids are contacted with the volauie solvent in stages to form a carrier solution which preferably is displaced by the volatile solvent, preferably by a countercurrent or crosscurrent contacting mode. to produce a slurry of insoluble solids with volatile solvent substantially free of the said liquid hydrocarbons to permit a separation and removal of said insoluble solids by gravity settling, preferably under centrifugal forces, sucn that a minimum of interstitial liquid containing a minor amount of the liquid hydrocarbons is discharged with the insoluble solids. The interstitial liquid, composed largely of the volatile solvent, is substantially recovered from the solids by evaporation. 
     The liquid hydrocarbons, including substantially all the asphaltenes and pre-asphaltenes, are thus effectively separated from the solids and can be in turn separated from the volatile solvent for conventional processing. High losses of the asphaltenes and pre-asphaltenes mherent in known processes, particularly for low rank coals such as lignite coals, are avoided.
