Patent MX-165273-B (MX)
Inventor: LU NICKY CHAU-CHUN
IPC: H01L21/74
Filed: 1987-10-02
Abstract: A fabrication process for providing an epitaxial layer on a silicon substrate and over predefined insulator-capped islands (18) which forms a self-aligned contact window in the epitaxial layer. Application of the method to a three-dimensional dynamic random access memory (DRAM) device structure is shown, with an access transistor (80, 84, 98) formed in monocrystalline silicon (30) stacked on top of a trench capacitor. A fabrication method therefor is shown wherein the contact window (52) for the source-to-trench connection is formed by self-aligned lateral epitaxial growth, followed by a contact-connection formation step using either a second epitaxial growth or a CVD refill and strapping process. The invention can be further applied to other device structures using the described principles, and more specifically to an inverter structure having the driver device stacked over the load-resistor as another example, which can be used as a basic building circuit unit for logic circuits and static-RAM cell.

Abstract: An incinerator system includes: a main chamber (32); double reburn tunnels (41,42); an excitor (134,158) within a reburn tunnel; a grate (234) near the incinerator's inlet (231) to permit the drying and initial combustion of refuse, and an ash scoop (278). The use of dual reburn tunnels (41,42), along with a damper (69,70) that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the main incinerator chamber (32) even with minimal refuse contained there. With less refuse, only one reburn unit (41,42) operates; it will still have sufficient heat and throughput to maintain, with minimal auxiliary fuel, the temperature needed for complete combustion. An excitor (134,158), or solid stationary object placed within the reburn tunnel (41,42), permits the retention and reflection of the heat generated by the burning to assure complete combustion of all hydrocarbons within the reburn unit. Additionally, the air utilized in the reburn unit may enter through the excitor for efficient distribution and concomitant combustion. <IMAGE>

Title: Process for the colorimetric determination of the cyanide concentration of aqueous solutions
IPC: G01N33/18
Filed: 1987-10-15
Abstract: According to the invention, cyanide concentrations of approximately 0.001 to 5 mg cyanide/1 are colorimetrically determined in a continuous manner by means of the known cyanidepicric acid color reaction. The solution containing free cyanide and/or cyanide releasable from cyanocomplexes is converted in a system enclosed in a gas-tight manner in the presence of chelate complexing agents, picric acid and alkaline buffer systems in 1-60 minutes at 50 DEG -120 DEG C. to the color complex and the absorbency is measured spectrophotometrically. The method avoids the extraction step which was previously necessary under 0.2 mg CN/1, avoids errors due to HCN gas evolution losses, is easy to manage, not prone to trouble and suitable for the continuous monitoring of waste-water streams or for controlling cyanide detoxification methods.

Title: Electrolytical process for extracting platinum of high purity from contaminated platinum.
Inventor: HERMANN SIGRID
IPC: C01G55/00
Filed: 1993-12-01
Abstract: The electrolytic process for obtaining platinum of high purity from a concentrated hydrochloric acid solution of contaminated platinum containing base and noble metal impurities includes electrolyzing the hydrochloric acid solution containing the contaminated platinum in an electrolysis cell subdivided by a cation exchanger membrane under potentiostatic or voltage-controlled conditions with a voltage of 2.5 V to 8 V applied across the anode and cathode under a current density of 0.3 to 12.5 A/dm2 so as to form a refined platinum-containing solution and a platinum alloy metal deposit. The concentrated hydrochloric acid solutions used in the process can have a contaminated platinum content of 50 to 700 g/l and total metal impurities of </=5000 ppm. In contrast to the known prior art processes, the process according to the invention operates with minimal requirements in terms of safety technology and equipment, causes a minimal environmental burden and is far less time-consuming and more economical.
