Patent DE-19717837-A1 (DE)
Title: Determining melanin affinity of test substances, e.g. drugs
Inventor: FEUERSTEIN THOMAS DR
IPC: G01N30/02
Filed: 1997-04-26
Abstract: High pressure liquid chromatography (HPLC) column for investigating the affinity of test substances (I) for melanin has a stationary phase (column filler material) consisting of silica gel to which eumelanin (EM) or phaeomelanin (PM) is covalently bonded. The EM is synthesised in vitro from L-dihydroxyphenylalanine (L-DOPA); and the PM is synthesised in vitro from L-DOPA and cysteine. The chemical bonding method also allows the use of melanins of biological origin, e.g. the melanin from the retina. For characterising the binding behaviour (corresponding to the affinity) of (I) with melanin, a defined amount of (I) is applied to the column and the corresponding retention is determined by isocratic elution. This retention depends on the amount applied and characterises the affinity of (I). The specific volume of the column is determined by applying sodium maleate having no affinity for melanin after each run.

Abstract: The memory device includes a substrate, a transfer FET formed on the substrate, a storage capacitor electrically coupled to either the drain or source of the transistor. Provided with the storage capacitor are a trunk-type conductive layer with a bottom electrically coupled to the drain/source region and with an upward extending part from the bottom.  A branch-type like conductive layer, shaped like a hollow pipe, and an end terminal of the branch-type like conductive layer is connected to the upper surface of the conductive layer. The end terminal extends upward with an approximately upward direction, an the trunk and branch conductive layers constitute a storage electrode of the storage capacitor. A dielectric is formed on the trunk conductive layer, and the exposed surface of branch down conductive layer. An upper conductive layer is formed on the dielectric to constitute an opposed electrode of the storage capacitor.
Patent DE-19721139-A1 (DE)
Title: Fuel burner off-gas re-circulation prevention method
Inventor: KOEHNE HEINRICH
IPC: F23C7/00
Filed: 1997-05-21
Abstract: The method involves using an adjustable stream or streams of air as a blocking medium which is used to eliminate or partly suppress off-gas re-circulation out of the combustion chamber. The air stream is restricted to the brief burner start-up period, adjusting the air stream by time or temperature. The air stream has both radial and tangential velocity components and should be imparted spin torque in or against the twist of the fuel and-or combustion air. The stream of air should be based on the geometry of the re-circulation holes to suppress off-gas recirculating from these, using a separate blower to the fuel blower itself to produce the air stream.

Patent DE-19742227-A1 (DE)
Inventor: WOLFRUM JUERGEN PROF DIPL PHYS
IPC: C12Q1/6874
Filed: 1997-09-25
Abstract: An extended fibre point (1) is coated with photobiotin and irradiated with U.V. light, causing the photobiotin to bind with the fibre point. The fibre point is then brought into contact with streptavidin and submerged in a solution containing dyed copies of the DNA molecule to be sequenced. Biotin is also bonded to the 5' end of the dyed DNA molecules (4A). The biotin coupled to individual DNA molecules binds with the streptavidin at the fibre point. Light is coupled into the fibre to detect the thus obtained bonds. The evanescent field of said light excites a dyed DNA molecule to emit fluorescent light as soon as it binds with the fibre point. When a bond is detected, the fibre is immediately removed from the solution, and the fibre point is inserted into a microcapillary (5). The microcapillary is filled with a buffer solution containing exonucleases which decompose the DNA molecule base after base. The outlet (6) of the capillaries is located in the observation zone of individual molecule detection equipment. In order to improve the signal-noise ratio for individual molecule detection, the walls of the microcapillaries have a thickness in the area of their outlet which is distinctly smaller than 1/4 the wavelength of the exciting light.
