IPC: G11C17/00
Filed: 1968-05-30
Granted: 1970-01-09
Abstract: 1,220,843. Integrated circuits. GENERAL ELECTRIC INFORMATION SYSTEMS ITALIA. 28 May, 1968 [30 May, 1967], No. 25487/68. Headings HlK and [Also in Division G4] The matrix of surface barrier diodes 7 shown is made from a silicon body la of low resistivity bearing a relatively resistive epitaxial layer lb The body is thermally oxidized and areas of the oxide over the epitaxial layer are removed to allow deposition of the gold surface barrier 5. Formation of the vertical conductors 4 (which lie on the oxide) is started by the vapour deposition of a pattern of Ni-Cr strips, upon which nickel is deposited without breaking the vacuum. An antioxidant layer of gold is then applied electrolytically and resistive bridges 6 of Ni-Cr are formed by vapour deposition. A thick layer of gold is then electrolytically deposited to complete the vertical conductors 4. Oxide is removed from the lower face of the body and a pattern of gold ohmic contact strips 2 applied-these function as a mask through which the body is etched to separate it into row strips which are held together by the vertical conductors 4. The matrix is converted to a read-only memory device by selectively energizing the conductors at power levels sufficient to burn out the resistive bridges 6 in the energized circuits. Such matrices may also be used in integrated logic circuits. Similar structures may be formed which include bipolar or field-effect transistors.

In a method of dyeing packed or wound textile goods, e.g. hanks, the dye liquor is pumped in a circular course and at a pressure in excess of atmospheric pressure within a closed vessel through the goods and is characterised in that the amount of dye liquor is kept in known manner so small that no noticeable amount thereof remains in the dyeing vessel, i.e. the amount of dye liquor only fills the pump, the conduits and the goods, and the delivery of the pump (m<SP>3</SP>/min.) is such that the quotient of the delivery of the pump (m<SP>3</SP>min.) and the amount of dye liquor (m<SP>3</SP>), i.e. the so called 'return' of the dye liquor per minute is greater than 8. Preferably the dyeing liquor temperature is more than 100‹C. and this is reached in as short a time as possible (2 to 8 minutes) and the 'return' of dye liquor is increased up to 20 while the degree of resistance of the goods to the passage of dye liquor is kept correspondingly small.
