Title: Semiconductor component with silylazide layer among diffusion barriers - improves step coverage characteristic by rendering diffusion barrier layer arrangement more amenable to metallisation
Inventor: LEE SANG-IN
IPC: C23C14/06
Filed: 1993-12-09
Abstract: The semiconductor substrate (11) is overlaid with a diffusion barrier layer (13) of Ti, a second layer (15) of TiN, and a third layer of TiN. Between the second and third layers, a reactively sputtered silylazide layer (23) is inserted from a source of SiH4 under partial pressure of 0.5 to 5 mTorr, to a thickness pref. of 20 nm. After formation of the second layer, the wafer can be transferred to another reactor without disturbance of the vacuum for the application of the silylazide layer. ADVANTAGE - Proper formation of diffusion barrier layer arrangement allows good step coverage of recesses for subsequent wiring layer, which are easily filled completely with metal.

Patent DE-4402734-A1 (DE)
Inventor: BECK ERHARD DIPL ING
IPC: B60T8/48
Filed: 1994-01-29
Abstract: The invention concerns a hydraulic brake system which, during skid control, operates in accordance with the recirculation principle, while a self-priming pump (11) draws in hydraulic fluid for traction control and delivers fluid to the brake (4) of a driven wheel. To ensure that a sufficiently large volume for traction control is available on the intake side of the pump, without high flow resistances occurring caused by the central valves in the master cylinder and by the change-over valve (14) in the intake line (13), the invention proposes that a suction reservoir (10) is fitted on the intake side of the pump (11), the reservoir automatically drawing in hydraulic fluid along the intake line (13) and through the change-over valve (14) and the central valves in the master cylinder (1) when the pump is carrying out its delivery stroke, i.e. displaces hydraulic fluid into the brake line.

Title: AIr-conditioning for switching cubicle
Inventor: NICOLAI WALTER
IPC: H02B1/56
Filed: 1994-03-19
Abstract: In a procedure for air-conditioning a switching cubicle using an air stream directed into the cubicle interior, a heat storage unit (30) is fed by warm air from the air conditioning apparatus (20). The air stream to be conditioned is then warmed or cooled by the warm air from the store. The thermal capacity of the heat store is brought up to a pre-determined level by the air flow through it and after the conditioning apparatus is shut down, the conditioned air is passed to the cubicle. The air is dried before entering the cubicle. In the upper region of the cubicle, air is extracted and directed to the surroundings or back to the heat store.

Title: Method and device for the freely selectable substitution of the uncoloured component in multicolour printing by black printing ink
Inventor: BLEKER SEBASTIAN
IPC: G03F3/08
Filed: 1994-03-25
Abstract: This is a method for the freely selectable substitution of the uncoloured component in multicolour printing by black printing ink on the basis of a spectrophotometrically scanned original, reference points in a colour space being obtained during the spectrophotometric scanning of the original. In accordance with a preselected degree, the uncoloured component or the complementary colour component of the colours of a printing colour space, constructed in a multicolour fashion, is substituted by black printing ink. Reference point data are registered photometrically from a colour scale which is specific to the printing process. The printing colour space is classified in a colour model (HSL model, Fig. 1) which is independent of printing colour and is represented in this model. A two-dimensional, nonlinear darkening field is formed using lightness values (Fig. 2) and a two-dimensional nonlinear desaturation field is formed with saturation values (Fig. 3), both of which are taken from the original, and the substitution of the uncoloured component by black printing ink is undertaken by means of iterative searching within the darkening field and the desaturation field. <IMAGE>

Title: Regenerating pickling soln. contg. hydrofluoric acid
Inventor: WIESENER KLAUS PROF
IPC: C23G1/36
Filed: 1994-10-04
Abstract: Regenerating HF-contg. pickling soln. used in descaling stainless steels, i.e. to remove non-reacted acids, comprises regenerating from the salts and recycling into the pickling electrolyte using electrodialysis, reducing by membrane electrolysis or chemically, and using electrolytic alloy deposition of Fe, Ni and Cr into membrane cells.  The waste stainless steel pickle is subjected to electrodialysis, to introduce H2SO4, membrane electrolysis, to reduce the trivalent Fe-cpds., and a further membrane electrolysis, to deposit metals. The acid regenerated in both membrane electrolysis steps is recycled into the pickling bath.  In the presence of nitric acid as oxidant, the additional electrodialysis step can be removed and recycled, together with the recycled material from membrane electrolysis into the pickling bath. A separate acid circulation is set up using H2SO4 in which the H2SO4 from the acid recycle of the membrane electrolysis is removed by electrodialysis by transferring into the pickling soln.  Metal deposition is carried out at a current density of more than 20 A/dm<2> using a continuously moving cathode, pref. a wire or strip electrode, to continuously remove metal. The deposition is carried out in membrane cells in which the pH of the soln. is 1-3. In place of reduction electrolysis, reduction using H2 with catalytically active elements or cpds., e.g. W-carbide, is used, pref. with metallic Fe.

IPC: G01N33/28
Filed: 1994-11-10
Abstract: Water content in the circuits of refrigeration systems is monitored by an arrangement of a narrow band single colour light source (1), e.g. LED, which illuminates a moisture indicator (2). Light reflected from the indicator illuminates an optoelectronic sensor (3), the output voltage from which depends on the intensity of the reflected light. The signal is compared (6) with a predetermined voltage from a set point generator to control a switching stage (7). A pref. light source has a broad spectrum and the receiver has a broad band response to the compsn. and intensity of the three primary colours. Output value is stored in accordance with the 'teach-in' method and the chromacity value as varied by the change in moisture content is compared corresp. to the setting of the following comparators to initiate a switching procedure.

Title: Method for picking up and representing thermographic images
Inventor: WOLLNIK H
IPC: A61B5/00
Filed: 1981-05-26
Abstract: The method for picking up and representing thermographic images of biological or technical structures, allows the sensing of abnormal temperature repartitions even when they are very low or when the corresponding areas differ very slightly as to their temperature values with respect to adjacent temperature values. According to this method, the temperature values for each image point of a thermogram are digitally picked up and recorded and the pitch of the local temperature variation is calculated, that is to say the temperature gradient for each image point in relation to its temperature and to the temperature value measured for the point adjacent thereto. For a selected image area, the local repartition of temperature gradients is represented. Abnormal temperature repartitions may thus by sensed, from such representation, where important temperature gradients exist.
