IPC: B01J20/32
Filed: 1988-12-21
Abstract: To prepare a polysaccharide matrix to which haptens are covalently bonded, polysaccharide-containing material is made alkaline, dried to a water content of less than 5 % and then reacted in anhydrous medium with hapten containing at least one active functional group. A device suitable for carrying out this process has a winding core (3) in a container for reaction solution (1), which has a tube (11), which is provided in its wall (5) with a plurality of openings (7) and is closed at one end (9), to receive a winding (13) of the material to be treated, and has two axial end discs (15, 17) to seal the axial face of the winding (13), and the device has a circulating pump circuit (19) which conveys the reaction solution from the container (1) to the other end (21) of the tube (11).

Patent EP-0341361-A3 (EP)
IPC: A61M16/04
Filed: 1988-09-19
Abstract: An endotracheal or tracheostomy tube or catheter is 
described which is provided with a loose-fitting cover 
over the mouth of the tube and means to remove the cover 
once the tube has been correctly inserted into for example 
the trachea or nasal passage. The cover prevents mucus 
entering the mouth of the tube. Moreover when the tube is 
provided at the inserted end with an outer sleeve or 
balloon which may be inflated with air or liquid so that 
it acts as a gas seal and cushions the internal tissues of 
the patient, the cover also acts to protect the inflated 
balloon.

Title: Push button switch with touch and locking function
IPC: H01H13/50
Filed: 1989-01-07
Abstract: A slide (2) in the housing (1) can move along a switching path (S) from a quiescent position into a switched position and back. The locking function is achieved by means of the interaction of a pin (6), supported on a moving bearing (8), with a guide curve (5, 13) which on the one hand has a locking step (b) and on the other hand, in the movement direction of the slide (2), has a linear extension (13) in which the pin (6) rests in the quiescent position of the slide (2). In order to simplify a space-saving design and functional movement it is provided that the bearing (8) can move parallel to the slide (2) between a first and a second position. It is further provided that, in the quiescent position of the slide (2), when the bearing (8) is located in the first position (Fig. 2a), the switching path (S) is shorter than the distance (A) of the pin (6) from the locking step (b) and is greater than said distance (A) when the bearing (8) is located in the second position (Fig. 2b).

Filed: 1989-05-29
Abstract: According to the present invention, one surface of a resistor 
plate (7) is arranged to face first electrodes (4) which are 
formed on a first region of one surface of a semiconductor 
element assembly. One surface of a conductor plate (5) is 
arranged to face the other surface of the resistor plate (7). 
Pressure is applied to the other surfaces of the semiconductor 
element assembly and the conductor plate (5), to form junction 
surfaces between the first electrodes (4) and the resistor 
plate (7) as well as between the resistor plate (7) and the 
conductor plate (5) to connect them with pressure. This 
structure is equivalent to inserting resistors between the 
first electrodes (4) and the conductor plate (7). Such 
resistors uniformalize distributed or partial currents flowing 
in respective parts of the semiconductor element assembly, 
whereby any local current concentration can be prevented, to 
thereby improve switching characterizistics and controllable 
gate turn-off current.

Filed: 1989-07-07
Abstract: A monobeam system for determining concentration 
changes of chromophore substance in a sample includes a 
flash lamp for passing a light beam through a sample 
containing the analyte. The values of absorbance by the 
sample at multiple wavelengths are measured and the 
optimum linear combination of absorbance values is 
determined to obtain a measure of chromophore 
concentration. Extinction coefficients for a chromophore 
is measured employing Deming's method and eigenvector 
transformations. A matrix reflecting the noise pattern 
of the system is determined. This matrix and the 
extinction coefficients are used in determining the 
coefficients for the optimum linear combination. An 
electronic module converts analog intensity data into 
digital data for five wavelengths. This is processed 
into absorbance values and concentration determinations.

Abstract: A method of fabricating a semiconductor device in an inte­

(37) is deposited on a substrate (17) in which source, 
drain and gate regions (29,31,19) have been created. A 
titanium nitride layer (39) is applied as a cap over the 
titanium layer (37). A first anneal at a relatively low

which are adjacent the silicon surface to form a titanium-­
silicon compound and causing the remaining titanium and 
titanium nitride to form a nitride coating. This nitride 
coating is etched away and a final high-temperature anneal 
is performed, resulting in thick, smooth titanium silicide 
(TiSi₂) layers on the source and drain regions and gate 
pads.

Abstract: The apparatus has a vacuum chamber (10) with an anode (11). A loading plate (16) for the substrate (18) to be coated is arranged as a first cathode, a distance away from the anode (11). A volatilisation electrode arrangement (40) of the nonvolatile substance to be transported is arranged as a second electrode a distance away from the anode (11) and from the loading plate (16) in the vacuum chamber (10). Furthermore, the discharge voltage source (24) for generating a potential difference between the anode (11) and the first cathode (16) and a volatilisation voltage source (44) for generating a potential difference between the anode (11) and the second cathode (40) are provided. A reactive gas is passed into the vacuum chamber (10) through a reactive gas pipe (32) entering the vacuum chamber (10). A gas mixture of a reaction gas and a carrier gas can be passed into the vacuum chamber (10), through a reaction gas and carrier gas pipe (52), in such a way that the volatilisation electrode arrangement (40) is surrounded by the gas mixture of the reaction gas and the carrier gas. The transport compound, which may be dangerous, can then be synthesised within the receptacle of the vacuum chamber (10). Sufficient coating even of part surfaces of the substrate (18) which point towards the loading plate (16) is ensured by the unoriented distribution of the transport compound in the vacuum chamber (10) and the essentially omnidirectional field distribution of the electric field around the substrate (18). <IMAGE>
