Abstract: 944,764. Circuits employing bi-stable magnetic elements. GENERAL ELECTRIC CO. Ltd. Aug. 8, 1962 [Aug. 11, 1961], No. 29066/61. Heading H3B. A matrix panel comprises two magnetic thin film planes having co-ordinate word read/write conductors and digit write/sense conductors, corresponding digit conductors 8a, 8b, Fig. 2, in the two planes being connected in series with the secondary winding 17 of a transformer 13, with the sense output obtained between a centre tap on the secondary winding and the junction of the two conductors. To write a word, a selected word conductor in one of the planes is pulsed in coincidence with digit pulses applied to the primary windings 14 of respective toroidal transformers 13, the closed circuits provided by the pair of digit conductors connected to each transformer preventing the digit pulses from paralysing the sense amplifiers. The easy axis of each film is parallel with the word conductors, and in accordance with usual thin film techniques the word write pulse is terminated before the digit pulses. Matched terminating resistors 18 may optionally be provided. In a modification, Fig. 4, the digit pulse source is connected to the primary winding 14 of a transformer 13 having a centre tapped secondary winding 17 supplying two transformers 21, 22. Looped conductors 19a, 20a and 19b, 20b are used, each loop forming a single digit conductor arranged in a single plane with transformers 21, 22 coupling the conductors with transformer 13. The looped ends of conductors 19a, 20a and 19b, 20b respectively may be either directly connected or earthed through matching resistors 23-26. The construction of a matrix panel is shown in Fig. 1 in which magnetic thin film 1 is deposited by evaporation to a thickness of about 800 Š on the two outside surfaces of a U-shaped sheet copper substrate 2. Each film is overlaid by an insulating film 5 of polyethylene terephthalate which carries closely spaced pairs of copper foil conducting strips 6 and is secured by cement, each pair of strips being short circuited at one end and forming a single word read/write conductor. The coordinate digit drive conductors 8 are formed as single copper foil strips cemented to plastic. The assembly is covered by a further insulating film 7 and is clamped in position by copper strips 9 and 10 with one end of each group of digit conductors soldered to strips 9. Each transformer 13 is located as shown, and the sense output is taken by way of coaxial conductors 4 which pass through a slot 3 in the substrate. Specification 928,874 is referred to.
