Abstract: Auf ein Substrat (1) werden nacheinander eine Metallschicht (4) und eine erste Ätzresistschicht aufgebracht, worauf diese erste Ätzresistschicht mittels elektromagnetischer Strahlung, vorzugsweise mittels Laserstrahlung, in den unmittelbar an das spätere Leiterbahnmuster angrenzenden Bereichen entfernt und die dadurch freigelegte Metallschicht (4) weggeätzt wird. Danach wird eine zweite metallische Atzresistschicht (7) aufgebracht, worauf die nicht dem Leiterbahnmuster entsprechenden und damit unerwünschten Bereiche (6) anodisch kontaktiert werden und hier dann die zweite Ätzresistschicht (7) elektrolytisch abgetragen wird. Zur Fertigstellung der Leiterplatte brauchen dann nur noch die unerwünschten Bereiche der Metallschicht (4) abgeätzt werden. Die Strukturierung mittels elektromagnetischer Strahlung kann rasch vorgenommen werden, da die größeren Flächen zwischen den Leiterbahnen zunächst noch stehen bleiben und erst danach durch das anodische Strippen und nachfolgende Ätzen mit geringem Aufwand entfernt werden.

Abstract: The device has a container (10) with two chambers (12, 13) arranged parallel next to one another for receiving two components which react with one another and an opening (14) with two concentric opening regions (15, 18) connected in each case to the chambers (12, 13). A static mixer (11) which has a sheath-like dividing element (24) at its input end can be screwed on to the container opening (14). In the assembled state, the dividing element (24) closely adjoins the cylindrical dividing wall (16) separating the two areas (15, 18) of the container opening (14) from one another. As a result, the point at which the two components are combined is distanced in the axial direction from that point at which the component lines are interrupted when the mixer is taken off, so that clogging of the container as a result of mutual entrainment of the components is prevented.

Abstract: A method for controlling an AMT system (10) is provided including sensing vehicle start from stop operation, determining a target engine speed value based upon the operator setting of the throttle pedal (THL) or of the sensed engine torque and modulating the fuel supplied to the engine to cause the engine speed (N) to rapidly equal and then be maintained at said target engine speed value. The clutch (16) is engaged at a relatively slow first rate, or a relatively rapid second rate depending upon the value of engine speed (N) relative to the target value and upon the value of the amount (FC) and/or the rate of change of the amount of fuel supplied to the engine. The first rate of engagement is a function of, and varies directly with, the value of operator setting of the throttle (THL) or the value of the engine output torque.

Abstract: Infrared proximity fuze, obtained by joining two IR proximity sensors (1), (2), preferably of the open field type, which have a different total field of view so that the target source presence signal is given by the simultaneous presence of an alarm signal coming from the greater field of view (FOV1) sensor and a time gate (5) generated by an alarm signal coming from the lesser F.O.V.(FOV2) sensor. Given the carrier-to-target movement characteristics and the aperture of the two fields of view (FOV1,FOV2) it is possible to electronically generate a time gate which rejects false targets (fires, flares, etc.) placed at considerable distances from the line of sight. The system is moreover intrinsically protected against the effects of solar radiation combined with the nutation and precession movements of the carrier because it requires simultaneous signal presence within both fields of view. The open field fuze signal processor checks for simultaneous a presence of a positive IR signal and of a negative rate of change of the IR signal, both characteristic of an emitter coming out the sensor F.O.V.

Abstract: An improved inverter AC power supply comprises a chopper providing a DC voltage from an AC source voltage and an inverter providing from the DC voltage a high frequency AC voltage to a load. The chopper comprises a pair of first and second switching elements operating to turn on and off for obtaining a periodically interrupted AC voltage which is rectified and smoothed to provide the DC voltage to the inverter. The inverter is arranged to share the first and second switching elements in common to the chopper and operates to drive the same switching elements for switching the DC voltage in order to provide a desired AC voltage to the load. The power supply is provided with an input power sensor monitoring an input power supplied to the chopper and an output power sensor monitoring an output power from the inverter to the load. A power controller is included for controlling to vary at least one of a switching frequency and a duty ratio for the first and second switching elements in accordance with the monitored chopper input power and inverter output power in the direction of equalizing the input and output powers.

Abstract: A matrix addressable flat panel display (100) which can be directly interfaced with a conventional CRT graphics controller and which provides both superior display quality and reduced driver complexity as compared with conventional displays. The pixels in each row of the display are formed in every other column, and the pixels in every other row are laterally shifted in both location and colour with respect to adjacent rows such that the pixels in each column are of the same colour. The colour triads, in turn, are defined by first and second laterally adjacent pixels of one row and a third pixel residing in the column intermediate the first and second pixels and in a vertically adjacent row. Since each column contains pixels of only one colour and each row pair contains complete triads, the colour select circuitry of prior art arrangements is substantially eliminated, and the display/driver is compatible with a standard CRT graphics controller. Moreover, the triad aspect ratio is 1:1, resulting in superior image quality.
