The method of making borosilicate glass with a surface having reactive SiOH groups on it includes preparing a borosilicate glass melt and dissolving at least 30 mMol per liter of water in the borosilicate glass melt. The borosilicate glass contains from 70 to 87 percent by weight, SiO2; from 7 to 15 percent by weight, B2O3; from 0 to 8 percent by weight, Al2O3; from 0 to 8 percent by weight, Na2O and from 0 to 8 percent by weight of K2O. The borosilicate glass with the easily modified reactive surface can be used as a substrate for chemically covalent immobilization of reactive substances. This substrate can be used to make a biochemical chip, such as a DNA or gene chip, or dirt-proof window glass.

A method is for activating or deactivating at least one part of data stored in a memory arrangement of a microcomputer system, in particular one part of a program stored there. In the event of a manipulation of data stored in the memory arrangement by unauthorized third parties, a method having the following method steps may prevent utilization of the manipulated data reliably and effectively:a microcomputer-individual identifier is stored in a signed or encoded fashion a specifiable memory area of the memory arrangement;when the microcomputer system is started up, the signature of the identifier is checked or the identifier is decoded; andas a function of the result of the identifier, one part of the data is activated or deactivated.

摘要:
Membrane module and process for its manufacture, wherein the membrane module contains at least two groups of hollow-fiber membranes, the groups arranged in layers and capable of being fed independently by fluids. The membrane module has a housing shell comprising a channel-shaped housing middle section, open at the top, and adjoining end pieces, also open at the top and with a number of arms corresponding to the number of groups. The groups of hollow-fiber membranes are inserted as layers over one another such that they are arranged in the direction of the longitudinal extent of the housing middle section and substantially parallel to each other. The ends of hollow-fiber membranes of different groups are arranged in respectively different arms of the end pieces and embedded with a sealing compound such that at least one end of the hollow-fiber membranes is open. The housing middle section and end pieces are closed with a covering device in a fluid-tight manner, thus forming a space enclosing the hollow-fiber membranes that can also accommodate a fluid stream.

An optical parameter oscillator system is proposed for use in a continuous wave pump laser system having a single-frequency pump source. The system comprises a single-resonance resonator having a nonlinear medium to produce a first and second parametrically generated wave in response to the pump wave from the single-frequency pump source. The system includes means for controlling the cavity length of the resonator, means for controlling the pump frequency of the pump source and means for controlling the temperature of the nonlinear medium. The system provides for a reliable singly-resonant optical parametric oscillator capable of emitting laser light with high spectral purity and frequency stability over a wide spectral range and is resistant to mode hopping.

摘要:
A method for producing a hollow filament package by winding at least one hollow filament onto a rotating body in a plurality of layers in the form of coils using a traversing filament guide device, so that the coils form an angle with the longitudinal axis of the body, wherein the speed of rotation of the body and the traverse speed of the filament guide device are adapted to one another in such a way that, per layer, a plurality of first coils are laid down side by side between the end sections of the body and, after each forming of a first hollow filament coil, the speed of rotation of the body and/or the traverse speed of the filament guide device is changed in such a way that second hollow filament coils are formed on the first or the second end section, the second coils forming an angle with the longitudinal axis of the core greater than the angle formed by the first coils.
