Patent EP-0304754-A2 (EP)
Inventor: HONIG HELMUT DR
IPC: C09D5/44
Filed: 1988-08-13
Abstract: The invention relates to a process for catalysing the crosslinking of cathodically depositable surface coating binders based on resins carrying ethylenic double bonds. The process is characterised in that, before the addition of water, 0.01 to 2.0% by weight, preferably 0.1 to 2.0% by weight, calculated relative to metal and based on the nonvolatile binder content, of iron acetylacetonate are added to the resin and mixed in homogeneously. As a result of the use of these catalysts, the use of lead compounds, which would otherwise be necessary, can be dispensed with without the quality of the crosslinked coating films being adversely affected.

Title: Stromregler
Inventor: BINARSCH JURGEN DIPL-ING
IPC: H02M3/158
Filed: 1988-10-11
Abstract: Es wird ein Stromregler für eine induktive Last (M) vorgeschlagen, insbesondere für ein Proportional-­Magnetventil. Dabei ist der Spulenstrom (I) mittels eines Schaltreglers (K₁) auf einen Sollwert (I₀) regelbar. Die induktive Last (M) ist mit einer ersten Freilaufdiode (D₁) beschaltet. Es ist weiter eine zweite Freilaufdiode (D₂) mit höherer Durchlaßspannung als die der ersten Freilaufdiode (D₁) vorgesehen. Diese ist dann einschaltbar, wenn der Sollwert (I₀) des Spulenstroms (I) eine schnelle Absenkung erfährt. Der Stromregler hat den Vorteil, daß die magnetische Energie der Last (M) bei konstantem oder wenig geän­derten Sollwert (I₀) weitgehend erhalten bleibt. Durch die Umschaltung auf die zweite Freilaufdiode (D₂) ist aber auch eine schnelle Absenkung des Spulenstromes (I) möglich.

Patent EP-0280438-A2 (EP)
Inventor: CHEN TU
IPC: G11B5/82
Filed: 1988-02-10
Abstract: A method for manufacturing a disk includes the step of forming a first nickel-phosphorus alloy layer 11 on an aluminum substrate 10, e.g., by electroless plating. A second nickel-phosphorus layer 12 is then sputtered onto the first nickel-phosphorus layer 11, and a magnetic alloy 13 is sputtered onto the second nickel-phosphorus layer. The magnetic alloy is typically sputtered immediately after the second nickel-phosphorus layer is formed without removing the disk from the sputtering apparatus between the time the second nickel-phosphorus layer is formed and the time the magnetic alloy is formed. Because of this, contaminants are not capable of lodging on or affecting the surface of the disk prior to formation of the magnetic alloy 13. The second nickel-phosphorus layer 12 is typically amorphous and therefore masks any nonuniformities in the surface of the first nickel-­phosphorus layer 11. Because of this, the second nickel-phosphorus layer 12 serves as a uniform nucleation surface for forming the magnetic alloy, and thus the magnetic alloy exhibits uniform magnetic characteristics.

Abstract: A distributed feedback semiconductor laser is provided with first and second grooves (15, 16), a mesa stripe (18) which is positioned between the first and second grooves, and a third groove (17) communicating with the first and second grooves (15, 16) and positioned behind a mesa stripe edge (19) at which the mesa stripe (18) is terminated. Each of the first and second grooves (15, 16) and of the third groove (17) is formed beyond an active layer (3) from a cladding layer (5). The width of the mesa stripe (18) is narrowed continuously at the mesa stripe edge (19) in the direction of the third groove (17) and the width of the third groove (17) is less than the sum of widths of the first and second grooves (15, 16) and the mesa stripe (18). The edges of the first and second grooves (15, 16) and of the third groove (17) are defined to be of a continuous shape. As a result, leakage current flowing outside the active layer (3) in the mesa stripe (18) is avoided, so that the oscillation threshold current is lowered even although the distributed feedback semiconductor laser is provided with a window region (21).

Abstract: The disclosure describes a method and system for cancelling noise from sources that are distributed over a region, whereby two sensors are located so that a first sensor will detect both voice signals and noise signals, and a second sensor will detect only the noise signals. The voice signals picked up at the second sensor are negligible, and the noise signals picked up at both sensors are correlated. The signals output from each sensor are connected to means to divide each respective signal into a predetermined number of frequencies, such as 15 for example. Thereafter, both signals are combined to cancel effectively the noise component from the signal output having both voice and noise to leave a voice signal that is substantially noise free.

Abstract: A method for inserting coils (2) in stators of electric motors, using an insertion tool (4) (consisting of insertion strips (6, 7), a supporting arrangement (5) and a shaft (16)) and using a pusher (21) with a tubular shaft (20) is improved. The object of being able to insert the coils (2) more easily and quickly is achieved in that these are inserted, formed in an extremely flat manner, into the forks (17) of a transfer tool and are pushed out of the forks (17) into the insertion strips (6, 7) by means of the pusher (21). The pusher (21) is improved by means of a special coil holder (23, 24) and a covering plate (25). The insertion of the wedges is also significantly accelerated with the aid of a wedge magazine having guides which are filled in advance at a different point. As a result of the use of supporting arrangements (5) of the same type, but stepped in size, for the insertion tool (4), the transfer tool and the wedge magazine, the storage holding is reduced (see drawing).
