Abstract: A circuit for providing an identification signal indicative of whether or not an integrated circuit has been repaired includes a circuit which operates at potentials outside the normal range of the integrated circuit. The circuit includes at least one transistor T1 serially connected between a TTL pin 10 of the integrated circuit and a fuse F1. The fuse F1 is also connected to a potential source VCC. If the integrated circuit is repaired the fuse F1 is opened, and consequently, application of a potential outside the normal range will cause current to flow if fuse F1 has not been opened, and cause no current to flow if fuse F1 has been opened.

Title: Process for feeding a stepping motor
Inventor: MOKDAD MOHAMED
IPC: H02P8/02
Filed: 1984-09-12
Granted: 1988-12-22
Abstract: A method of controlling a stepping motor comprises supplying the motor with a predetermined quantity of energy Eio from whence there will result an automatic adaptation of the width of the motor drive pulse to the voltage Uo at the motor terminals and the resistance Ri of the energy source. At the moment when the internal energy Ei(t) supplied to the motor, as defined by the integral over a time period of the product of Uo-RI and the current It circulating in the motor winding, becomes equal to Eio the drive pulse is cut off (R is the resistance of the motor winding). The circuit for practicing the method according to the invention includes means for measuring the voltage Uo and the energizing current I(t), means for obtaining the difference Uo-RI, a multiplier for forming the product (Uo-RI)I(t) and an integrator the output of which provides a voltage proportional to the internal energy Ei(t).
