Title: Improvements in the manufacture of nickel-iron alloys
IPC: B22F9/22
Filed: 1942-07-16
Abstract: 578,193. Nickel -iron alloys. GENERAL ELECTRIC CO., Ltd., and CHIRNSIDE, R. C. July 16, 1942, Nos. 9906 and 10737. [Class 82 (i)] The manufacture of a nickel-iron alloy comprises forming a mixture of a nickel-containing substance and an iron-containing substance in which the two metals are present in substantially the proportions required in the final alloy. A substantial part, and preferably the whole, of the nickel or iron or both is present in the form of the sulphate or sulphates NiSO4.7H2O and FeSO4.7H2O. If only one sulphate is used, the other metal may be present in the metallic form or as an oxide. The mixture is heated so that any sulphate is converted to oxide and is further heated in a reducing atmosphere to reduce the oxides to metal and if necessary further heated in a neutral or reducing atmosphere to complete the formation of the alloy. The heating in a reducing atmosphere may be performed in two stages, in the first of which the temperature is maintained lower than that employed in the conversion to oxide, and in the second stage a higher temperature, may, be employed. A temperature of 850‹ C. to less than 1000‹ C. is referred to in connection with the reduction. The starting-materials may be used in powder form intimately mixed, the alloy being obtained in powder form or as a slightly sintered aggregate which can be reduced to powder form, for example by ball milling.

Title: Photoimaging processes and compositions
Inventor: CORDES WILLIAM FREDERICK
IPC: G03F9/00
Filed: 1996-06-19
Abstract: The step-on-wafer process, also known as the step-and-repeat alignment process, for the production of very large scale integration (VLSI) microcircuitry with multi-layer interconnects, is greatly facilitated by incorporating, into at least the first layer of photoresist, a dyestuff which meets certain criteria the chief of which is that it be transparent to radiation to which the photoresist system is sensitive and that it absorb radiation of a wavelength to which the photoresist system is not sensitive. The use of photoresist systems in association with such dyestuffs has additional advantages. For example, the thickness of the photoresist layer deposited on a substrate can be checked prior to imaging without activating the photoresist.
