Abstract: L'invention concerne un procédé et un appareil de pulvérisation pour déposer de l'aluminium sur un substrat à semi-conducteur (19) en vue de remplir des interconnexions entre couches d'un micron et moins, utilisant de l'énergie sous la forme d'ultrasons pour assurer un remplissge efficace de ces interconnexions. Le semi-conducteur est supporté par un bloc (16), chauffé et soumis à une énergie sous forme d'ultrasons supérieure à 25 kHz, pendant que l'aluminium est déposé par pulvérisation sur la surface du substrat (19). On fait varier la fréquence des ultrasons entre 35 et 42 kHz lorsque l'aluminium est déposé, pour éviter la formation d'une onde stationnaire ou de noeuds sur la surface du substrat. Ceci permet l'application de l'aluminium et le remplissage efficace et de bonne qualité des interconnexions du substrat à semi-conducteur.

Title: Web monitoring for paper machines
Inventor: PARKER JOHN RUSSELL
IPC: G01N21/892
Filed: 1995-05-26
Abstract: An apparatus for web monitoring in paper making machines comprises a row of two or more lookers (6, 8) which are spaced across the width of the moving paper web. Each looker is stationary, and continuously inspects one or more small areas of the web as the web passes beneath. Optical signals form each individual inspection area are digitised, and spatial filtering is used to remove from the signals the effects of variations in the web which are much larger or much smaller than the variations being studied. A number of power spectra are calculated from the spatially filtered signals, and analysis of these functions is then used to identify significant features. Plots or tables of such features can be used to provide detailed information for the machine operator on the types of variations that are occurring in the paper web, and the possible causes of these variations.

Title: Process for electrochemically dissolving a metal such as zinc or tin
Inventor: MOOIJ JOOP NICOLAAS
IPC: C22B7/00
Filed: 1995-07-19
Abstract: The object of the invention is to provide for an improved electrochemical dissolution process for electrochemically dissolving a first metal by simultaneously creating hydrogen evolution at a second metal, the second metal being a metal that has a larger current exchange density for hydrogen evolution than the first metal, both metals being immersed in an aqueous electrolyte system, wherein the first metal and the second metal are galvanically coupled. By taking measures to reduce inhibition of said hydrogen evolution at said second metal the rate of dissolution of the first metal is enhanced. The measures to reduce said inhibition comprise suitably selecting temperatures and concentrations of the electrolyte, dividing the electrolyte into two fluids coupled by a selectively permeable device and suitably selecting the resistance value of a connecting means electrically connecting the first and the second metal. The invention is particularly useful for removing Zn or Sn from Zn- or Sn- containing steel scrap.

Inventor: CRAWFORD ROBERT D
IPC: G06F13/24
Filed: 1997-02-11
Abstract: A method or protocol for generating an Interrupt Signal for communication between a peripheral device and a host processor having either a level-sensitive or an edge-sensitive interrupt detector. After receiving an active interrupt request, and after confirming that the Chip Select signal is released, the interrupt signal is transitioned to an active level. After receiving an active Chip Select signal and multiple Clock pulses from the host as confirmation of receipt of the Interrupt Signal, the Interrupt Signal is transitioned to its inactive state.  If the interrupt request is still pending, and when the Chip Select signal is released, then the Interrupt Signal is again made active.  Maintaining the active level for the Interrupt Signal until the confirmation is returned from the host will activate level-sensitive detectors, while edge-sensitive detectors in the host will be activated by the multiple transitions ocurring if the host does not service the interrupt request in the peripheral.
