Patent DE-2023741-A1 (DE)
IPC: H03K3/84
Filed: 1970-05-14
Abstract: 1291522 Testing digital circuits INTERNATIONAL BUSINESS MACHINES CORP 14 May 1970 [19 May 1969] 23368/70 Heading G1U [Also in Division G4] A logic circuit 20, Fig. 2, is tested by applying successive combinations of input signals to both the circuit 20 to be tested and a reference logic circuit 30 and, for each input signal combination, sensing the amplitude of the voltage at each pin of the circuit under test relative to upper and lower thresholds and comparing the sensed amplitudes with the signals at the corresponding pins of the reference circuit.  Applying the input signals. A pseudo-random number generator 10 produces a random sequence of 48-bit numbers which are applied to gating circuits in a buffer 70. The gating circuits are controlled by a register 60 such that the output of the buffer 70 changes from one number produced by generator 10 to the next in 48 steps, only one bit changing at each step. The 48-bit output of buffer 70 is applied directly to the reference logic circuit 30 and, via a pulse shaper and synchronizer 80, to the logic circuit 20 under test. The buffer 70 also includes, for each bit, provision for over-riding the signal from the random number generator and forcing a '1' or a 'O' to be applied in series with a resistor to the relevant pin, enabling selected input pins to be maintained at a constant level and ensuring that the output pins are correctly loaded. Comparing the output signals, Fig. 4. The signal from each pin of the circuit under test is applied to two threshold circuits 92, 94. If the circuit under test is satisfactory, a '1' output will exceed the upper threshold and a 'O' output will be less than the lower threshold and thus the output should never be between the two. The outputs of the two threshold circuits are compared with the output of the corresponding terminal of the reference logic circuit 30 in a circuit 41-45 which produces an error signal whenever there is a discrepancy between the two logic circuits, or the output of the circuit under test lies between the two thresholds. Such an error signal, unless suppressed by the absence of a 'test on' signal on gate 47, causes an OR gate 49 to provide an error warning which stops further testing. Checking of the input pins ensures that open or short circuits are detected.

Title: Cuprous oxide coatings for copper wire - by direct current heating in borate solution bath
Inventor: BELLINGER KURT
IPC: C23C22/52
Filed: 1973-05-10
Abstract: In the production of copper sheathed wires for fusion into glass, coatings of cuprous oxide can be produced on the surface of copper wire by boratizing. The copper wire or strip is drawn continuously through a bath contg. an aq. soln. with boric acid and/or borates, pref. 0.5-50 g/l alkali borates. Heating is by direct passage of an electric current through the copper strip or wire. The Cu2O coating which is soluble in glass and produces excellent adhesion prevents contact with CuO which would be detrimental for the glass/metal seal. This is a simple and economic means of processing prior to fusion into glass.
