Abstract: This invention relates to a pretreatment process for galvanized metal which, unlike existing processes, was specifically developed for galvanized metal. Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation is necessary as is required with existing processes. Also, the invention relates to the galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating. Galvanized metal treated by this pretreatment process prior to coating leads to a uniform coating which is impervious to acid, base and salt solutions, and which will not scratch or flake off on impact.

Granted: 1989-03-01
Abstract: The power consumption and corresponding speed of an integrated circuit is scaled by means of adjusting the channel width for MOS transistors. A transistor (12) is initially fabricated with a channel (24) having a width W1. The channel (24) receives a depletion type implant (30) to make the transistor (12) lightly depleted. An enhancement implant (32) is applied to the channel (24) to cover a selected area (24a). The enhancement implant (32) is made substantially stronger than the depletion implant (30). This results in a first section (24a) of the channel (24) having a large threshold voltage while the second section (24b) of channel (24) has a relatively small pinch-off voltage. The size of the second section (24b) is selectively controlled to scale the source-drain current of transistor (12) and the corresponding power consumption of the transistor (12). The method of applying the first and second implants (30, 32) can be easily incorporated into conventional ROM fabrication without the need for additional manufacturing steps.

Abstract: A process for automatically going into the mode for increased suction extraction of the gases emitted by the tanks of series for the production of aluminium by igneous electrolysis using the Hall-Heroult process, each tank being closed around its periphery by a plurality of removable covers which are disposed in substantially sealed relationship with each other and between each thereof and their support means on the periphery of the tank, the gases being collected over each tank by at least one duct connected to a centralized suction extraction system. The temperature of the gases in the duct is continuously measured. Opening of at least one cover gives rise to an abrupt drop in temperature, which makes it possible to put the system into the increased suction extraction mode, which will be automatically stopped when, all the covers being closed again, the temperature of the gases will substantially resume its initial value. The power required for the suction system is thus substantially reduced.
