Inventor: RUTA JOSEPH W
IPC: H02H3/093
Filed: 1986-09-25
Abstract: control circuit (16) is provided for a circuit interrupter (400,410) that achieves an inverse-time characteristic for overcurrents that include instantaneous current levels higher than the instantaneous interrupting capability of the circuit interrupter by synchronizing the operation of the circuit interrupter to ensure that circuit interruption takes place when the instantaneous current is within the interrupting capability of the circuit interrupter. This interrupting capability is similar to let-through current and is defined by the instantaneous magnitude of the current at the time of interruption or at a particular stage thereof. The control circuit is responsive to a time-current characteristic signal generator (120) that provides a time-current signal (TCS at 126) in response to overcurrent after the passage of a time delay that is inversely related to the overcurrent. The control circuit utilizes the time-current signal to permit asynchronous operation (via 184,180,176,162) of the circuit interrupter when the peak of the overcurrent is expected to be within the interrupting capabilities of the circuit interrupter and to control operation of the circuit interrupter in a manner synchronized with the overcurrent (via 192, 196) when the peak of the overcurrent is expected to exceed the interrupting capabilities of the circuit interrupter; the interruption in the synchronized manner being arranged to occur when the instantaneous current is within the interrupting capabilities of the circuit interrupter. In a preferred arrangement, the rate of change of the current (M at 188) and the instantaneous current level (e.g.l L ) are utilized to decide if the overcurrent may include instantaneous current levels higher than the instantaneous interrupting capabilities of the circuit interrupter. If such overcurrents are predicted, the rate of change of the current and the instantaneous current being within a predetermined current range (l l  - I H ) are utilized to synchronize operation of the circuit interrupter.

Abstract: An apparatus for automatic inspection of printed circuit board assemblies inspects for the correct presence, positioning, and orientation of component parts mounted on a base printed circuit board. In this method for inspection of printed circuit board assemblies, an arithmetic comparison operation is conducted on several color pictures of different colors taken of the base printed circuit board mounted with the component parts; and a distinction is made between parts of the base printed circuit board not occupied by the component parts, and the component parts. Optionally, one of the base printed circuit board and the component parts is tinted in a color of a category selected from the group consisting of the green category, the red category, and the yellow category. The arithmetic comparison operation may be division, or may be subtraction. The base printed circuit board may be coated with a preflux mixed with a fluorescent agent, which may be green; or may be coated with a bonding agent mixed with a fluorescent agent, which again may be green. Illumination may be provided by a light source whose wave length varies from visible blue to ultraviolet. The color pictures may be taken by a color TV camera.

Abstract: The bonding of semiconductor chips to a substrate is described wherein the first step involves the bonding of a tacky, curable and partially cured chip bonding adhesive, which is releasably supported on a support film, to the surface of the chip intended to be bonded to the substrate. The second step involves the further partial heat curing of the adhesive to convert it to a non-tacky state so that the adhesive will not undesirably stick during handling and storage operations. Thereafter, the chip with its adherent adhesive can be mounted to a substrate at elevated temperature to convert the adhesive to a more tacky state. The final step involves the curing of the adhesive after it has been used to bond the chip to the substrate.

Abstract: In recording/reproducing apparatus, pilot signals of different frequencies (f₁ to f₄) are recorded cyclically and in a predetermined sequence on parallel record tracks on a moving record medium (2) together with an information signal organised in a series of fields. The pilot signals are employed to control tracking of a reproducing head (H A ,H B ) of the apparatus during reproduction. During reproduction, the record medium (2) is transported at a predetermined speed and phase relative to the reproducing head (H A ,H B ) in order to generate reproduced pilot signals and a reproduced information signal. The reproduced pilot signals are multiplied in a multiplier (6) with reference pilot signals (REF) switched in accordance with a head switching signal (SWP), thereby generating an output from which a tracking error signal is derived. The tracking error signal is sampled and held (15) at predetermined times in a plurality of fields. A comparator (16) effects a comparison of the sampled-and-held signal with a reference signal (V REF ) and produces a comparator output signal (LOC) having a state that depends on the comparison. A head clogging detector (100) is responsive to the comparator output signal (LOC) for effecting detection of a head-gap clogged condition of the reproducing head (H A ,H B ).

Abstract: The invention refers to a pressurized container, usable within the framework of the classic sprays, in which the content is released by the pressure exerted from outside to inside, for which purpose the container is made of an elastic material, that in recovering its original shape, causes releasing of the contents, when the corresponding valve is opened. This elastic flexible body is in the form of a tube, closed at one end and attached to said outlet valve at the other, which may also be used for filling, or the filling valve may be situated at the closed end of the tube. This tube is accompanied by an outer casing giving the container as a whole a suitable form, as well as the necessary stability, with a mass of spongy material situated between the tube and outer container, which aids in the container tube 'rtself's recovery of shape.

In der Einspritzleitung 7 ist ein elektromagnetisches Abschaltventil 8 angeordnet, mit dem die Kraftstoffzufuhr beim Öffnen des Zündanlaßschalters 10 zwecks sofortigen Stillsetzens der Brennkraftmaschine 1 unterbrochen wird. In der Abgasleitung 4 ist eine Lambda-Magersonde 12 angeordnet, die ein dem Sauerstoffgehalt des Abgases entsprechendes Signal einer Vergleichselektronik 14 zuführt, in wlecher dieses Signal mit einem Lambda-Sollwert verglichen wird. Wenn beispielsweise durch einen Fehler im Einspritzsystem eine Kraftstoffübermenge eingespritzt wurde, unterschreitet der von der Lambdasonde 12 festgestellte Wert den Sollwert, worauf die Vergleichselektronik 14 einen Schalter 15 aktiviert, der in der Steuerleitung 9 des Abschaltventils 8 angeodnet ist. Dadurch wird die Stromzufuhr zu dem Abschaltventil 8 unterbrochen und die Kraftstoffzufuhr zur Brennkraftmaschine 1 abgesperrt. Ein unbeabsichtigtes Hochdrehen der Brennkraftmaschine durch fehlerhaftes Einspritzen einer Kraftstoffübermenge wird hierdurch verhindert.

Abstract: A method and device for measuring clearances between gears of an internal gear having an inner gear and an outer gear. With the inner gear fixed, the outer gear is set around the inner gear and brought into abutment with the inner gear at one side. The outer gear is then moved in the opposite direction to butt the inner gear at the other side. The clearance between the two gears is determined by measuring the distance for which the outer gear moves. This method is much simpler and time-saving than a conventional method using clearance gauges.
