Patent EP-0546852-A1 (EP)
Inventor: ZAROWIN CHARLES B
IPC: H01L21/302
Filed: 1992-12-11
Abstract: A gas, which is flowed into a plasma chamber  12  positioned "upstream" from a etching reaction site on a substrate  20 , is converted into a plasma and its active species by the application of excitation. The means for excitation may be radio frequency power or microwave power. The excitation is decoupled from the substrate so as to prevent "print through" effects caused by electrical and geometric characteristic of the substrate. The active species are then flowed "downstream" from the plasma chamber  12  to the surface of the substrate  20  through an outlet  16  having an interactive flange  18  attached to the terminal end. The interactive flange  18  provides a surface separate from the substrate to consume the active species. The interactive flange inhibits the etching reaction from occurring outside of the local material removal footprint. The distance between the outlet and surface of the substrate is adjustable to provide a means to control the material removal footprint and removal footprint profile.

Abstract: An unwinding carriage (14) is supplied with a fibre web (4). This unwinding carriage (14) is moved to and fro, thus causing it to deposit the web (4) onto an exit conveyor (8) driven transversely to the movement of the unwinding carriage (14), so as to produce a lap (6) consisting of successive lengths of web inclined alternately relative to the longitudinal direction of the exit conveyor (8), these lengths being connected by means of folds defining the edges of the lap produced (6). The advance of the exit conveyor (8) is maintained at the moments of the changes in direction of the unwinding carriage (14). During these changes in direction, the quantity of web (4) unwound is restricted, so as to exert on the fibres between the exit conveyor (8) and the unwinding carriage (14) a pull which tends to orient the fibres forming the folds of the web in the lap (6) parallel to the longitudinal direction of the exit conveyor (8). The invention is used particularly for making needled products. <IMAGE>

Abstract: A bale of straw (16) is conveyed on a raking table (13) against a raking tool (1) with a movable grate (7). The raking tool is driven through a gear (11) and a crank by a raking motor (12). The raking table is driven through a gear (18) by a constant torque motor (17) provided with a detector (19), by means of which tile speed of the raking table (13) is detected. When a speed below a predetermined value is detected, the power supplied to the drive motor (17) of the raking table is increased to a higher level. If it is detected that the drive motor (17) of the raking table is supplied with power at a higher level and that the raking motor (12) simultaneously uses a small amount of power, the grate (7) is for a short time moved in the direction away from the bale of straw (16), the raking tool (1) getting a bigger penetration depth, after which the grate (7) is brought back to its starting position.

Abstract: A further development of a nail file gives a nail file which has at least one file groove 2 coated with sapphire, the sapphire being held in a nickel layer. Whereas previously in the case of such nail files the entire surface was inevitably nickel-plated, which is expensive and limits the possibilities of providing an attractive surface design, the novel nail file is only subject to nickel plating insofar as the sapphire is to be bound. For this purpose, the file body 1 is provided according to the invention with a slot 4 and the file groove 2 is designed as an insert part made of nickel-plated plastic and adapted to the slot 4. The novel nail file is distinguished by a low expenditure on nickel plating, furthermore by the possibility of being able to freely select the surface design in other respects. The insert part can have a connecting web 3 on its lower side. Moreover, the insert part or the connecting web 3 can be provided with lateral projections or cutouts which interact with corresponding cutouts or projections in the slot 4 of the file body 1. <IMAGE>

Abstract: A corrosion protect film is coated on a steel substrate by the following process of the present invention. A primer paint includes as a pigment a zinc powder and as a vehicle resin an initial condensate obtained by hydrolysis of at least one alkoxysilane which is expressed by the following formula; 
 
 
 
        Si (R₁) x  (OR₂) 4-x   
 
 
 
wherein R₁ stands for a C₁ to C₅ alkyl group or alkenyl group, R₂ stands for a C₁ to C₅ alkyl group, and x is 0 or 1, or a mixture of a colloidal silica and the initial condensate. The primer paint is coated on the steel substrate, and then dried to obtain a primer film with corrosion and heat resistance. A powder paint having a thermal shrinkage stress of 40 kg/cm² or less is coated on the primer film, and then baked thereto at a baking temperature to form a powder paint film thereon. Therefore, the corrosion protect film substantially consists of the primer film and the powder paint film. The process of the present invention is useful for providing the corrosion protect film with good adhesion strength to huge steel structures such as ships, plants, and bridges, etc., which are severely attacked for many years by the environments.
