Abstract: Appareil électronique de mise en image comprenant un dispositif opto-électronique (50) qui, après avoir été adressé électriquement avec des informations d'images et après avoir été éclairé par diffusion, produit l'affichage d'une image lumineuse bidimensionnelle statique. Le dispositif de la présente invention comprend un organe électronique (60, 51, 52, 13) permettant de former un motif de charge électrostatique (correspondant à l'image lumineuse à afficher) sur une surface d'un panneau opto-électronique (11). Un agencement d'électrodes (12) reliées à une tension de référence (par exemple la masse) agit de concert avec le motif de charge pour produire des champs électriques de modulation de lumière dans le panneau, ces champs électriques étant utilisés à leur tour pour moduler en fonction de l'image l'intensité de la lumière traversant le panneau. L'image lumineuse produite par le dispositif dure jusqu'à ce que le motif de charge se dissipe (ce qui peut prendre plusieurs heures, en fonction de la constante diélectrique de la surface de support du motif de charge).

Abstract: A mechanically rigid joint is formed between two different metals by completing the joint in a forging operation. A part (14) made of one metal is placed in a die form (20) and is maintained at a temperature below that required for forging. A billet (23) made of the material from which the second part (13) is to be formed is placed in the die (20) so that the billet (23) can be formed into the second part (13), engaging the first part (14) at an interface (16) defining the joint. The joined parts (13, 14) are then machined into their final shape. The joint (16) is stabilized by maintaining appropriate temperatures of the materials to compensate for expansion and contraction after forging, and by providing suitable coatings for the materials, particularly at the interface (16). 
     Advantages include reduction in weight and increased stability of a final assembled component because the two parts are joined without the use of fasteners or other conventional techniques.

Abstract: @ The automatic wafer alignment technique may be used in a step-and-repeat photomicrolithographic exposure system accurately to prealign a wafer before exposure to the B-level and subsequent reticles and automatically to align the wafer at each die site prior to exposure. A search technique optimizes location of the global targets (36') used for wafer prealignment. The search begins at the most likely target position and proceeds through a search area established by the maximum expected rough prealignment error. A wafer alignment target (36') configuration consisting of a cross with one elongated arm (36Y') and a short crossbar (36X') is used to optimize target verification. Such verification is carried out by successively examining the middle, right and left arm parts and area of the wafer beyond the arm to determine whether the expected target features are present or absent. 
     To locate targets, a video image is digitized and the average intensity at each video scan line and column is obtained and stored in a "data buffer" memory. The intensity differences between successive points is measured, and the signs of successive intensity differences are used to determine whether consecutive points belong to a run to points having the characteristics of a feature edge.

IPC: H03K7/06

Abstract: A charge balance voltage-to-frequency converter utilizes CMOS circuitry to provide a digital pulse output proportional to an analog input signal. The converter approaches a desired charge balance by cycling between a charging and a discharging state. A clock signal provided by a stable oscillator (118) is applied to a clock input of a CMOS D-type flip-flop (116). The analog input signal (Vin) effectively is fed to a non-inverting input (103) of an integrating amplifier (104). The output (114) of the integrating amplifier (104) is fed to the D input of the flip-flop (116), which input has a threshold level. The Q output of the flip-flop (116) is connected via a voltage divider (119) to an inverting input (112) of the integrating amplifier (104). This . configuration eliminates the need for a dual polarity power r supply. When the output (114) of the integrating amplifier (104) rises above the threshold level of the D input, on the next rising edge of the clock signal, the flip-flop (116) sends feedback pulses to the inverting input (112), thus beginning the discharge state. Each feedback pulse causes the integrating amplifier (104) to discharge a predetermined amount. When the output of the integrating amplifier (104) falls below the D input threshold level, feedback pulses are inhibited, and the charging state begins again. The output pulses from the flip-flop (116) when accumulated over a period of time, represent the charge required to balance the charge provided by the input signal (Vin). The feedback pulses are summed by an accumulator (130) to provide an indication of the converter input.

Abstract: Der Abgaspartikelfilter (1) weist im Kern (2) eine parabelförmige Aussparung (2a) auf, welche dafür sorgt, dass die Zuströmung der Abgase zum Zentralfilterteil (4) kanalisiert werden. Dieser weist gegenüber dem Aussenfilterteil (3) - bedingt durch grössere Filterporosität und kleinere Masse - einen kleineren Abscheidegrad auf, so dass die Abgase in der Anfangsphase durch den Zentralfilterteil (4) strömen werden. Seine grössere Filterporosität und die kleine Masse bewirken, dass die Temperaturabsenkung der durchströmenden Abgase klein bleibt, so dass ein nachgeschalteter Lader rasch ansprechen wird. Da die Abscheidung der Russpartikeln vorerst primär im Zentralfilterteil (4) stattfindet, wird sich hierin - trotz seines geringeren Abscheidegrades - rasch eine starke Ablagerung ergeben, wodurch der Widerstand in den der Beschleunigungsphase folgenden Betrieb sich demjenigen des umliegenden Aussenfilterteils (3) angleichen wird. Dieser bietet sodann die Kapazität, über eine längere Periode ohne Regeneration Russpartikeln abzuscheiden.
