Electroless plating device
permanent magnets on a first yoke plate having a circular border, the magnets of this continuous row all having the same polarity, at least one magnet on a second yoke plate having a circular border, at least one magnet being of a second magnet arrangement having the opposite polarity, such that over the target plate at least one tunnel is formed of magnetic lines of force issuing from the first magnet arrangement and returning to the second magnet arrrangement or vice versa, and with a driving means for the continuous rotation of the second magnet arrangement about the central axis of the target plate.
Electroless Plating Device U.S. Patent5,284,520. Feb. 8, 1994 A. Tanaka,assignorto Mitsubishi Den/d, Tbkyo
An electroless plating device, which comprises an electroless plating tank, a workpiece holder, a draft pipe for blowing air into the plating solution to form bubbles, and a shield plate having perforations provided between the object of plating and the bubbles blown out from the draft pipe, whereby the bubbles cannot pass through the perforations.
Recirculation Ventilation System
tion to determine the difference between the amount of Fe+3 added to the sample and the amount of free Fe+3 found in the sample; and calculating the complexing power of the liquid based on the difference.
U.S.Patent5,284,518.Feb. 8, 1994 M.7:Kahn, assignor fo Be/co Muskies Inc., Be/ding, Mich. A ventilation system for a spray booth wherein the housing has a single opening and conveyor means is adapted to bring workpieces into and out of the space through the single opening.
Sputtering Apparatus U.S. Patent 5,286,3&I. Feb. f5, 1994 J. Szczyrbowski et al, assignorsfo l_eybo/dAG, Hanau,Germany
Analysis Method for A Pickling Liquor
An apparatus for coating a substrate, especially with electrically nonconductive coatings, from an electrically conductive target in a reactive atmosphere, comprising an evacuable coating chamber, a directcurrent source, a magnetron cathode disposed in the evacuable coating chamber and containing a target and a magnet, which cooperate electrically with the target and whose sputtered particles deposit on the substrate.
U.S.Patent5,286,358.Feb. 15, 1994 KS Fletcher and J.K. Burdick, assignors to The FoxboroCo.,Foxboro,Mass. A method of determining the iron complexing power of a liquid including hydrofluoric acid, fluoride ions, nitric acid, and complexed iron, comprising the steps of obtaining a test sample of the liquid; adding a known amount of Fe+3 to the test sample, in stoichiometric excess of the amount necessary to complex with all available fluoride ions, such that the Fe+3 ions complex with essentially all of the available fluoride present in the sample, yielding iron-fluoride complexes and uncomplexed Fe+3; performing a back titra-
