Title: MOS transistor technology - employs high dose ion implantation and simultaneous gate and field oxide growth
Inventor: BUSSMANN EGON DIPL PHYS DR
IPC: H01L21/762
Filed: 1979-10-15
Abstract: This technology employs a method of producing MOS transistors whereby the field oxide and gate oxide are produced simultaneously, thus avoiding the problems of nitride separation, tension stresses and the white ribbon effect. This is accomplished by implanting high dose ions in the field oxide regions and then building up the gate-and field oxide in a temperature of between 550 deg.C and 700 deg.C simultaneously. The silicon substrate is masked with a photo-lacquer coating (2). The implanting of the high dose ions in the field oxide region results in the formation of regions (3) in the substrate. During the subsequent oxidation at a temperature of 620 deg.C an oxide growth ratio of 6 to 1 is achieved. Repetition of the process increases oxide growth even further.

Title: Diagnostic procedure by temp. measuring - calculating temp. of acupuncture point by rate at which miniature temp. sensor changes to equalise temps.
Inventor: PITTERLING PETER
IPC: G01K13/00
Filed: 1979-10-24
Abstract: The rapid temp. measuring procedure esp. for acupuncture diagnostics allows a miniature temp. sensor to be used. The place to be measured and the sensor start from different temps. The sensor is brought to the place concerned and during the measuring process their temps. correspond in dependence on time. The measuring place temp. derived from the course of the time dependent temp. change function of the temp. sensor is approachingly calculated as a power of the theoretical final temp. of the sensor corresp. to the temp. at the measuring place. The measuring process is then interrupted. The measuring process can begin at a set time point (E1) after the sensor has been set in position on a acupuncture point or head zone. The process is then broken off after predetermined measuring period (delta t).

Inventor: POLZHOFER KURT DIPL CHEM DR
IPC: G01N33/02
Filed: 1980-04-23
Abstract: Rapid determination of dissolved aflatoxins is effected by chromatography on a mini chromatographic column and comparison of the colour or fluorescence intensity of the resulting aflatoxin zones or bands with those of chromatogram zones or bands of a standard substance in known, graduated concns. in a similarly fitted control column, the colour or fluorescence intensity of the standard substance corresponding substantially to those of the aflatoxins to be determined. The mini chromatographic column is filled, in order (bottom upwards) with a layer of glass wool, granulated sodium sulphate, magnesium silicate gel ("Florisil"(RTM)), silica gel, neutral alumina, granulated sodium sulphate and a sealing layer of glass wool and is activated by heating 2 hrs. at 110 deg. A measured amt. of the solution mixture to be examined for aflatoxins is applied to the column, then the column is developed by descending chromatography using a suitable solvent mixture. Used for determination of aflatoxins, esp, in plant and animal extracts, e.g. to determine aflatoxins B1,B2,G1 and G2 in foodstuffs. Simple and rapid procedure which, because descending chromatography is used, permits the amount of developing solvent to be accurately measured and therefore gives improved reproducibility.
