Title: Method for encapsulating semiconductor sensors
Inventor: HOFFMANN WERNER DR RER NAT
IPC: G01D11/24
Filed: 1989-06-22
Abstract: The invention relates to an encapsulation method for sensors based on electronic components (semiconductor sensors). The invention can be used whenever it is necessary to cover a sensor surface with the encapsulation material in such a way that one or more sensitive windows should be left free, these being in direct contact with the measurement medium and being used for signal generation (microstructuring of the encapsulation material). According to the invention, this object is achieved in that a structured chemically stable photopolymer produced in a lithographic process directly constitutes the encapsulation material on the sensor surface, which leads to a highly productive encapsulation method.

Title: Method for the spinning of opened fibres of linear textile structure on the principle of discontinuous fibres and apparatus for carrying out the method
Inventor: TRAN VAN QUYEN DIPL ING
IPC: D01H4/06
Filed: 1989-06-24
Abstract: In a method for spinning of opened fibres of linear textile structure, the fibres are conveyed by suction in an air stream into a spinning chamber which is formed between a conical rotor rotating at high speed and a stationary hollow cone. The air stream passes through the rotating cone in the region of the axis of the latter, with the result that the fibres accumulate in the region of the tip of the rotor. The apparatus for carrying out the method consists of a spinning chamber or of a spinning cavity (1) which is limited by a stationary hollow cone (3) and by a conical rotor (2) forming a twisting nozzle and provided with a suction channel (7), of a drawing device (5) and of an outlet nozzle (8). <IMAGE>

Patent DE-4024734-A1 (DE)
Inventor: HUMS ERICH DIPL CHEM DR
IPC: B01J37/00
Filed: 1990-08-03
Abstract: In catalysts for use in hot exhaust gases with a surface-roughened metal bearing structure and a catalytically active coating applied thereto, there is the problem that the catalytically active coating can fall off the metal bearing structure. It is therefore the aim of the invention to improve the adhesion of the catalytically active substance to the bearing structure. To this end, according to the invention, the metal bearing structure is roughened by spark erosion. Then the catalytically active coating can be keyed to the metal bearing structure roughened by spark erosion with the aid of a cross-linking agent. The invention is applicable to catalytically coated plate catalyst systems.
