Abstract: An air-tight vat (10) under pressure completely encloses a rotatable drum (12). The vat (10) is constructed so that it may be completely submerged in liquid. The vat has a liquid filled take-off chamber (32). The pulp is fed to the vat through a pulp inlet (14). The pulp is formed and compacted to form a pulp mat. Directly following the forming and compacting of the pulp is a washing zone for washing the pulp mat. After washing the pulp mat is again compacted. The pulp mat is removed from the drum at a removal point located in the liquid filled take-off chamber, thus providing a pulp suspension in the take-off chamber. The suspension is removed from the vat through a pulp outlet (61) extending from the liquid filled take-off chamber (32).

Abstract: A print head for a light emitting diode printer has a row of LEDs (11) on a mother plate (10) and an end mounting plate (16) secured at each end of the mother plate (10). A linear lens array (14) is positioned over the LEDs (11). The optical elements of the print head are adjusted by mounting these components in a fixture having an optical image analyzer (41) for analyzing the quality of image from an individual LED (11) projected onto the face of the analyzer (41). The total conjugate or spacing between the row of LEDs (11) and the image analyzer (41) is adjusted for maximizing image quality. One end of the lens array (14) between the LEDs (11) and analyzer (41) is adjusted for maximizing the quality of an image of an LED (11) on the optical analyzer (41). The spacing of the second end of the lens array (14) is then adjusted for maximizing the quality of an image of an LED (11) near the other end of the row (11). The adjustment steps may be repeated for optimizing the LED images. After adjustment, the position of the lens array (14) is locked in the end mounting plates (16). A bearing reference surface (38,39) on each end plate is locked against a reference surface (48) on the analyzer (41). when the print head is mounted in a printer, the reference surfaces (38,39) on the end mounting plates (16) serve to position the print head with the LED images focused on the photoreceptive surface (36) of the printer.

Abstract: In the coating blade 1 which is bent in an S-shape by means of a pressure strip 9 for the purpose of applying its pressing force, for the purpose of profile correction an additional force of the profile correcting device 2 is exerted by means of magnets 4, 5. This additional force preferably acts counter to the main pressing force F. In this way, a change in the geometry of the coating blade in the contact area, i.e. in the area of its coating edge, is prevented from occurring by the profile correcting device.

Filed: 1991-04-30
Abstract: A method to minimize disturbance of an already programmed antifuse while programming other antifuses in a circuit includes the steps of determining a preferred order in which to program the antifuses and programming them in the preferred order. High initial programming and soak currents are selected such that the disturb current is small with respect thereto. The magnitude of the disturb current is increased to a value that maintains the antifuse resistance or improves it rather than adversely affect it. Where a circuit node containing a first already programmed antifuse is positioned such that parasitic capacitances may discharge through that antifuse during the programming of a second antifuse, the magnitude of the charge stored at parasitic capacitances associated with the programming path is reduced by reducing the programming voltage when this programming situation is detected. After the initial rupturing of the antifuse dielectric is detected, the programming voltage is increased to its normal value for the soaking period.
